8 TREATMENT PLANT OPERATOR
The other night I had a dream. I dreamed I woke up one morning to find out that our
federal government had adopted a comprehensive energy policy. (OK, I didn’t really have this particular dream, but bear with me.)
This policy was not some hodge- podge of here-today/gone-tomorrow grants, loans and incentives for this or that form of green or sustainable energy. It was an actual policy with defined roles for coal, nuclear, nat-ural gas, diesel gasoline, wind, solar, geothermal and, yes, biogas.
And what a great thing it was. No longer would major energy decisions be based on private com-panies’ short-term economic con-
siderations — like closing and tearing down a perfectly good, newly refurbished and relicensed nuclear plant near my hometown, because right now it’s cheaper to make elec-tricity with natural gas and coal.
Instead, long-range thinking would apply. In the above example, the federal government would subsidize the nuclear plant’s power to keep it open, since in time we’d need that reliable, clean, greenhouse-gas-free energy, and at some point its price would again be market-competitive.
RUDE AWAKENING
But of course I woke up to reality. The nuclear plant was still gone. And as far as the eye could see we’d continue, as a nation, making stupid decisions about energy.
I wonder, if we had an actual energy policy, what that would mean for biogas from the nation’s clean-water plants — those with anaerobic digestion, anyway. This one seems like the ultimate no-brainer. Clean-water plants all over the coun-try have anaerobic digesters that produce methane. Many do not use them to produce energy. What stands in their way? More often than not, it’s the up-front investment in engine-generators or combined heat and power (CHP) systems.
Treatment plants increasingly are recognized as resource recovery facilities. One of their resources clearly is energy. Biogas-to-energy systems, based on what I have seen and
let’s be clear

Hey, a Guy Can DreamWHAT IF THE US HAD A STRATEGIC ENERGY POLICY, DEFINING ROLES FOR EACH ENERGY SOURCE AND BACKED BY MAJOR FUNDING? WHAT MIGHT THAT MEAN FOR CLEAN-WATER PLANTS AND BIOGAS?

read, yield a pretty good return on investment and relatively attractive simple payback times.
WHERE’S THE DOWNSIDE?
It stands to reason that a national energy policy would aggressively encourage biogas-fueled CHP. Digestion of bio-solids alone can produce substantial gas and energy. The gas burns clean and in many or most cases would displace power from more-polluting sources like coal-fueled power plants. And once a facility has digesters, it’s natural to feed them food waste, FOG and other high-BOD waste products, yield-ing even more gas. That brings the extra benefit of keeping those materials out of landfills, with all the cost and envi-ronmental risk they can entail.
How much potential is there for biogas-to-energy? How much biogas do we produce today versus what we could produce if the resource was fully developed? Well, a few years ago, the North East Biosolids and Residuals Associa-tion (NEBRA) collected data on biogas production at clean-water plants across the United States.
The survey found that 1,238 treatment plants use anaer-obic digestion and produce biogas, mostly at larger facilities (flows exceeding 1 mgd). On the other hand, two-thirds of the 3,300 or so plants above that size threshold do not pro-duce biogas. And only a small number of plants with flows below 1 mgd do so.
So only a fairly small percentage of the nation’s 15,000 to 16,000 permanent treatment facilities produce and use bio-gas. To be fair, some of these are small package plants, but the survey did find some small facilities with anaerobic digestion — plants with flows from 1 to 5 mgd, and even some with less than 1 mgd. Some of these use biogas to gen-erate electricity.
WHAT’S THE POTENTIAL?
Another study, the 2014 Biogas Market Snapshot from XPRT Media, said the United States had the world’s greatest untapped biogas potential, and that from all sources — clean-water plants, farms and others — this country could produce nearly 70 million MWh of electricity per year from biogas.
That won’t solve all the country’s energy challenges, but it does compare to the output from several 1,000 MW utility power plants, and that’s a substantial amount of renewable energy.
So if our country had a real energy policy, maybe we’d see incentives put in place to encourage anaerobic digestion and biogas-to-energy. Such incentives could include low-interest loans structured so that the loan repayment would “cash flow” from the energy cost savings (and revenue).
Then perhaps we’d have this valuable resource on the way to being fully developed. That would be a boon to our energy supply, the environment and our economy — not to mention a dream come true.
Clean-water plants all over the country have anaerobic digesters that produce methane. Many
do not use them to produce energy. What stands in their way? More often than not, it’s the up-front investment in engine-generators or combined heat and power (CHP) systems.

BEING SMALL IS NO REASON TO CUT CORNERS. That’s a reason the Mechanic Falls (Maine) Sanitary District has a formal biosolids management plan, even though it serves just 3,100 people and moves just 23 dry tons of material per year.
“It’s about saying what you do and doing what you say,” says Nicholas “Nick” Konstantoulakis, district director. “It’s a booklet that tells exactly
what we do, where we do it and how we do it. When regulators know that you have a program in writing for anybody to see and you have a history of fol-lowing it, you’re fine.”
The plan is built in the model of the National Biosolids Partnership Envi-ronmental Management System (EMS) program. The district land-applies liquid, lime-stabilized biosolids on a farm 6 miles from its 490,000 gpd

(design) clean-water plant. The management plan spells out every detail of procedures. All land application takes place in October. The entire process — lime addition, hauling, spreading, testing, recordkeeping — costs about $15,000 a year.
HOMEGROWN TALENT
Konstantoulakis, a Maine native, has been with the district for 10 years and director for two. He served in the U.S. Air Force for four years after high school, lived in Texas for nine years working and attending Sam Houston State University, then returned to Maine, where he put his industrial tech-nology studies to work in laboratory positions with electronics manufacturers.
His quality assurance experience from those jobs helped him make a
career change. “I was bored with what I was doing,” he recalls. “When you work in a lab, you pretty much do the same thing day in, day out.”
He and 11 others applied for an opening at the Mechanic Falls district. Then-director Tom Schultz chose Konstantoulakis largely because he was familiar with the ISO 9000 international quality standard, similar in char-acter to National Biosolids Partnership’s EMS: “Tom wanted to do the EMS, and I was a perfect fit.”
EFFICIENT TREATMENT
Mechanic Falls, in southern Maine, has a 33-year-old activated sludge treatment facility using a racetrack-style oxidation ditch. The community is all residential and light commercial, which means flows rates and influent quality are consistent year-round.

Wastewater (250,000 gpd average flow) passes through a Worthington comminutor for preliminary treatment and then directly into the 288,000-gal-lon oxidation ditch (Lakeside Equipment). A set of grooved, motor-driven, rotating paddles beat air into the mixed liquor. Konstantoulakis and assis-tant Brian Ahlquist achieve optimum removal of volatile solids by holding dissolved oxygen in the ditch at 0.8 mg/L, with help from oxygen sensors (ABB Automation).
“We can control it manually, but generally we use our SCADA system,” Konstantoulakis says. “If it starts raining heavily or if the DO starts drop-ping for any reason, the paddles kick in automatically. Our SCADA pretty much takes care of it all.”
Water from the aeration process passes to two final clarifiers (Lakeside Equipment). After chlorine disinfection, final effluent averaging about 8 mg/L BOD and TSS is discharged to the Little Androscoggin River. “If you put a glass of drinking water beside a glass of our effluent, you couldn’t tell the difference,” Konstantoulakis says.
TO THE FIELDS
On the solids side, waste activated sludge is pumped to a pair of 150,000-gal-lon storage tanks, where it accumulates until land application season in Octo-ber. Two Sutorbilt blowers (Gardner Denver) mix the material; there is no digestion. Material enters the tanks at about 3 percent solids, and periodic decanting raises the solids content to 4 percent.
Just before land application the tank contents are lime stabilized. After an initial pH reading on the material, lime slurry is delivered to the tanks by a trash pump until the pH reaches 12, a process that takes about 30 min-utes. The pH is held at that level for two hours and rechecked the next day. A year’s biosolids production is typically about 140,000 gallons.
HOSTING THE YOUNG ONESAs director of the Mechanic Falls Sanitary District, Nicholas
“Nick” Konstantoulakis has emphasized public outreach.“I’m trying to get the community more involved,” he says.
“When I started here 10 years ago, this district was the best-kept secret in town. You could drive by and you weren’t even sure what it was. When I bring people here, they can’t believe how beautiful it is. There’s no odor. My predecessor, Tom Schultz, ran the opera-tion like a military base in terms of being neat and clean. I’ve kept that up. We plant flowers. I planted 111 tulips, and 88 came up. For a plant that’s 33 years old, this place is looking pretty good.”
Konstantoulakis loves to bring in local fifth graders once a year: “They’re so much fun because they’re interested. I start by opening the manhole at the headworks and letting them look down there. They think that’s so cool. I have a safety barrier around it, and I say, ‘If you ever see a manhole open, make sure you call somebody.’
“I take them to the aeration basin and tell them, ‘This is as much a living thing as all of us here. It needs air, it needs oxygen, it needs food.’ Then I tell them that every time they flush the toilet, this is where it goes. I say, ‘Does anybody want to guess what’s out there?’ Always, some little girl will say, ‘Poop?’ And I’ll say, ‘That’s right — 288,000 gallons. And that’s good, because it’s in here and not in the river. We’re a wastewater treatment plant and proud of it.’”
As for adults around his own age, Konstantoulakis reminds them of days of the first Clean Water Act. “I’ll jokingly say, ‘Remember when you were a hippie in the 1970s and you wanted clean water? That’s what you’re paying for.’”
The Mechanic Falls plant uses an oxidation ditch secondary treatment process (Lakeside Equipment). The aerators are controlled automatically to sustain optimum dissolved oxygen.

A contractor delivers biosolids to the farm in a 4,000-gallon tank truck and surface-applies it to the field as directed by the landowner. The farm has 109 acres of corn and hay land permitted by the state Department of Envi-ronmental Protection. The lime-stabilized material, applied in cool autumn conditions, presents no odor issues.
“We don’t use all 109 acres,” Konstantoulakis says. “We apply about 600 pounds per acre. We do a chemical analysis on the material we spread, and about a month to six weeks later we take a soil sample and send it to the Uni-versity of Maine for laboratory analysis.”
The biosolids are tested for 25 parameters, including pH and nutrients, as well as heavy metals, which are nearly nonexistent. The contractor, at the district staff’s direction, observes required setbacks from roads (100 feet) and the farmer’s well (300 feet). No other homes are nearby.
“Our farmer loves the material,” Konstantoulakis says. “A brick cheese that was made from milk he supplied recently won an award. The cheese-makers were so impressed with the product that they put a picture of his farm on one of the packages.”
ACCORDING TO PLAN
The district’s process is fully documented in the biosolids management plan. The district joined the National Biosolids Partnership EMS program in 2007 and is also a member of the North East Biosolids and Residuals Association.
An EMS is a management framework that helps treatment facilities con-stantly improve in key areas, such as quality management, regulatory com-
pliance, environmental performance and relations with interested parties. “Our plan tells who the director is and who the helper is,” Konstantou-
lakis says. “It has sections on roles and responsibilities for each one of us. It describes our public participation plan, our process controls, our internal audits. There’s a section on management review and a section on chemical

To Konstantoulakis, the plan is helpful on various levels: “Because we have our procedures in writing, if I get hit by a bus tomorrow, the person I work with could easily take over. When we’re inspected by the DEP, they can look at our plan and see putting it into practice.”
The plan also helps the district run a consistent, clean operation and avoid alarming the public:
“It’s a win-win program that benefits us all. It helps us continue to ensure that our biosolids are of the highest quality and that our recycling program remains cost-efficient. There are a handful of people who are against land application, but they tend to be the same people who will go to a hardware store and buy fertilizer from another country, not even knowing where it comes from. We don’t look over our shoulder when we do this, but we do understand that members of the public who don’t understand it or have been misinformed might raise concerns.”

plant mechanic, and Ray Paczosa, plant electrician, pinpointed the cause. Rags had clogged a static mixer on the feed line in the CHP building, cre-ating back-pressure on the line. Once they removed the mixer, solids flowed to the digester. They also retrofitted the plunger pumps, rerouted piping and installed new timers.
“Bob came to the plant every weekend to check on the digester,” says Schick. “Without his commitment, I doubt we would have been as success-ful. While others lost faith, Bob always rose to the challenge.”
SEVERE INDIGESTION
More challenges were in store. A miscalculation placed the sludge level too close to the top of the digester tanks, causing violent agitation. The burp-ing, foaming material infiltrated and then blocked the output lines. Seeking an escape route, the material entered the gas piping, forcing operators to open pressure release valves instead of flaring the gas.
“After we reduced the sludge level by 10 to 15 per-cent, Joe Frates installed drainlines on the gas pip-ing, enabling operators to flush the system,” says Schick. “Assistant superintendent Rene Robillard was the lead on purging the entire gas system, begin-ning at the top of the digester and working back to
the CHP generator.” The fire department stood by to assist in case of an emergency.
The struggle to meet the startup deadline height-ened the operators’ stress. After learning new tech-niques, they had to relearn them as components and processes were re-engineered from within. Schick’s team spent two years modifying piping, adding chem-ical feed sites and reformulating how the facility wasted sludge.
While the adjustments benefited the digester, they often were not conducive to the main plant’s treatment train. Wastewater usually entered the pri-mary settling tanks at about 50 degrees F, but mix-ing it with hot solids from the digester’s return sidestream adversely affected the process.
“We’re trying to balance how we optimize the digester to get the profit we were hoping for, but also minimize the effect it has on the other side of the plant,” says Vincent Furtado, Board of Public Works superintendent. The successful marriage of new with old was hard-won. “The town had budgeted $500,000 for startup adjustments, but they cost an additional $1.5 million,” says Schick.
EVALUATING PERFORMANCEBecause the system is still in its infancy, projected savings are moving
targets. The process generates only enough biogas to heat the digester tanks and power pumps in the digester building. To increase methane production and reduce purchased gas from a third to less than a quarter, the town is con-sidering adding restaurant grease to supercharge the system.
Electric rates doubling in March also moved the number. “My normal electricity budget is $300,000,” says Schick. “I’m probably realizing a 20 per-cent savings from the CHP system and solar panels on three buildings after deducting maintenance and other costs.”
One solid benefit is the 50 percent reduction in biosolids sent for incin-eration. “We had 10 to 12 trucks hauling it away every week,” says Schick. “That’s down to four or five, reducing hauling costs by $130,000 last year.”

Hundreds of pounds of solids slipped downstream through worn equipment at the Fairhaven (Massachusetts) Water Pollution Con-trol Facility. The volume made it difficult for the plant to meet its
discharge permit.Looking for solutions, the town took part in a pilot study on anaerobic
digestion and combined heat and power (CHP) systems. “It concluded that although we are a small plant, the process could be cost-effective if we used glass-fused-to-steel tanks instead of concrete structures,” says Linda Schick, sewer and wastewater superintendent.
The $8 million project was financed by a principal-forgiveness loan through the American Recovery and Reinvestment Act (federal stimulus) and the State Revolving Fund Green Infrastructure. “We had two years to deploy the system or face repaying the money with 2 percent interest,” says Schick.
Challenges accompanied the integration of new technology with 28-year-old equipment, requiring operators to be constantly on call at first. “We almost didn’t make it,” says Schick. “Besides the generation gap, small-scale digestion is most successful on farms, where there are no other processes to integrate or sidestreams to absorb.” The team’s two-year effort made Fairhaven the second wastewater facility in the state to generate its own heat and energy.
SETTING THE TABLE
Built in 1969 and upgraded in 1989, the 5 mgd (design) activated sludge facility averages 3 mgd. Three 1987 plunger pumps on timers (Komline-Sanderson) feed pri-mary sludge to two fixed-cover Aquastore digestion tanks (CST Industries). Two chopper pumps (Vaughan Co.) circulate solids through mixing nozzles in the tanks. Two other pumps move material through the heat exchang-ers to maintain a constant 98 degrees F in the digester.
A gas conditioner removes water from the gas before it enters the MAN 100 kW CHP generator (Kraft Power Corporation), which runs on natural gas, biogas or a mix. Excess biogas is stored in a dual-membrane DuoSphere containment (WesTech Engineering) or flared through a burner stack (Varec Biogas, a division of Westech Industrial).
Digested biosolids are treated with ferric chloride, then dewatered in two 1-meter gravity belt thickeners (Komline-Sanderson). The resulting cake is incinerated by a vendor.
INTO THE FRAY
Plant designers were present during the CHP system’s startup in Sep-tember 2012, but Tom Bienkiewicz, director of the Massachusetts State Board of Certification of Operators of Wastewater Treatment Facilities, was pivotal in providing technical and moral support.
“He spent a lot of time and energy explaining to state Department of Environmental Protection officials why it was taking so long to get the pro-cess going,” she says. “Tom was our moral support. We even had his personal number, and he’d talk us through problems no matter when we called.”
Most repairs involved shutting down the digester, then starting up again from square one — a time-consuming process. It began the first day of startup when solids in the feed system never reached the digester. Increasing pressure burst an underground pipe, sending the material bubbling to the surface.

plant mechanic, and Ray Paczosa, plant electrician, pinpointed the cause. Rags had clogged a static mixer on the feed line in the CHP building, cre-ating back-pressure on the line. Once they removed the mixer, solids flowed to the digester. They also retrofitted the plunger pumps, rerouted piping and installed new timers.
“Bob came to the plant every weekend to check on the digester,” says Schick. “Without his commitment, I doubt we would have been as success-ful. While others lost faith, Bob always rose to the challenge.”
SEVERE INDIGESTION
More challenges were in store. A miscalculation placed the sludge level too close to the top of the digester tanks, causing violent agitation. The burp-ing, foaming material infiltrated and then blocked the output lines. Seeking an escape route, the material entered the gas piping, forcing operators to open pressure release valves instead of flaring the gas.
“After we reduced the sludge level by 10 to 15 per-cent, Joe Frates installed drainlines on the gas pip-ing, enabling operators to flush the system,” says Schick. “Assistant superintendent Rene Robillard was the lead on purging the entire gas system, begin-ning at the top of the digester and working back to

22 TREATMENT PLANT OPERATOR
LIKE A MASTER MUSICIAN, A WASTEWATER TREATMENT PLANT superintendent must make sure everything works in harmony — from equipment to oper-ators. That’s what Frank D’Ambrosia has been doing successfully for 11 years as superintendent at the Village of Archbold (Ohio) Wastewater Treatment Plant.
Since March 1, 2004, this easygoing former music teacher and traveling musician has over-seen a major expansion at the plant, 40 miles southwest of Toledo. He has also ensured that the 2.5 mgd facility meets all federal and state envi-ronmental regulations, kept the collections sys-tem functioning, and made sure his operators get the training they need to keep their certifica-tions. Such diligence has earned D’Ambrosia a rewarding career and an industry lifetime achievement award.
Last year D’Ambrosia received the William D. Hatfield Award from the Northwest Ohio Water Environment Association (NWOWEA). The award recognizes outstanding performance and professionalism over a career.
The awards program said, “Frank D’Ambrosia truly embodies what it means to be a consum-mate wastewater professional.” Citing how he organized and taught the NWOWEA’s semiannual Operator Education Day, which prepares opera-tors to take state wastewater certification tests, the writeup mentioned that D’Ambrosia has opened the plant to host many hands-on workshops for area operators and “routinely provides training to employees in many areas, including digester operations, secondary system DO control and proper
procedures for taking readings on sludge blan-kets, grit removal procedures and lab analysis.”
As for D’Ambrosia’s reaction, “I was very surprised,” he says in an accent that gives away his New Yorker background. “It’s quite an honor and one that reaffirms my belief that wastewater has been a great career that I’ve had the good fortune to pursue for the last 35 years.”
EXPANSION EXPERIENCE
D’Ambrosia started work life as a music teacher. Later, while touring with a five-piece band (see sidebar), he met his wife, Susan, who had family in Defiance, a city of 16,500 in north-western Ohio. In 1979, D’Ambrosia found a job at the city wastewater treatment plant, which “went from work-and-a-paycheck to a career.”
“A year later, we went down to south Florida, where I worked for about a year and a half,” says D’Ambrosia. “I first worked at a 2 mgd wastewa-ter facility for a private utility and got my Class A wastewater license. Then I moved to the Bro-ward County Wastewater Treatment Plant just north of Miami. When I started there the facility was under construction to expand from 20 mgd to 60 mgd. While in Florida, I gained a lot of
valuable knowledge that I brought back to Defiance.”D’Ambrosia worked his way up from operator to assistant superinten-
dent and experienced a plant expansion from 4 mgd to 6 mgd. He then moved to Archbold, a village of 4,300. Along the way, he got his Class III certification in wastewater.
The Archbold plant underwent a $6 million upgrade in 2006-07. The

24 TREATMENT PLANT OPERATOR
THE RIGHT TOUCH Orchestrating these projects, while maintaining 40 miles of sewer lines,
nine lift stations and an industrial pretreatment program, requires a deft touch and strong management skills. D’Ambrosia displays those qualities in abundance, says Dennis Howell, village administrator.
“Frank is an interesting guy,” says Howell. “He has a lot of interests and talents, including being a fine musician, and he’s very knowledgeable and astute in the wastewater field. Everybody has a lot of respect for Frank. If you can’t get along with him, it’s your problem. Frank fits in with our vision of being proactive in keeping our wastewater operators trained and their skills sharp.”
Of the plant’s seven operators (one a nearly full-time lab technician), five have Class III certifications and one has a Class I certification. Three know how to operate the plant’s combination cleaning truck to vacuum the sewer lines. D’Ambrosia sees that they get the continuing education they need to keep their certifications, learn new technol-ogies and maintain plant equipment.
“I do my own training,” says D’Ambrosia. “Through NWOWEA, I set up a half-day of training that we invite people in the community to come to. Plus, I do training with the operators, such as bringing in chlorine people to talk about chlorine application. Also, through the Ohio WEA, I set up a review ses-sion twice a year for young operators planning to take the wastewater certification exam. We have three sessions that day. I teach the basic wastewater course and have experts who teach advanced waste-water and do a review of the collections system.”
PRAISE FOR TRAINING
The operators are grateful for the education D’Ambrosia provides and for his collaborative man-agement style, which encourages them to take responsibility and run with good ideas. They credit him with keeping morale high and fostering a team environment.
“He’s a real good boss who lets us do what we need to do to get the job done,” observes Mike Short, assistant superintendent and maintenance chief. “Frank gives us free rein and doesn’t microman-age,” says Short, a Class III operator and 28-year plant veteran. “Frank is excellent when it comes to getting us training. If we get an email message about a program, say a motor or pump class, he’ll let us go, juggling the schedule so we’ll have people here to run the plant. We can go pretty much any-where in Ohio. It’s an asset to everybody.”
Randy Volkman, a Class III operator who has been at the plant for 19 years, adds, “Frank is an easy guy to work for. When we have bigger projects, we tell him and he gives us the green light to pro-ceed. He’s very supportive and gives us every chance to get the training we need to do our jobs better.”
For D’Ambrosia, it’s all part of being a good leader, as is a strong work ethic. That means getting in at 6:30 in the morning, checking the SCADA sys-tem, overseeing lab tests and addressing issues, from balky equipment to a homeowner with a backed-up sewer.
“Communication up and down is very impor-tant,” he says. “So is delegating — letting people take ownership of their work and become part of what’s being done, rather than wait to be told what to do. It’s what makes the job rewarding.”

renovation increased capacity from 1.75 mgd to 2.5 mgd with 5 mgd peak flow. It also added a grease removal system, new final clarifiers, a new fer-rous chloride storage tank, new chlorination and dechlorination systems, a new process monitoring and control system, and a new operations building. The project also included modifications to a tertiary lagoon to create an overflow basin that retains diverted influent over 5 mgd.
Today, the plant’s activated sludge process treats an average daily flow of 1.6 mgd and removes 96.8 percent of TSS, 99.1 percent of CBOD, 92.4
percent of ammonia and 90.5 percent of phosphorus. Effluent discharges to Brush Creek, which flows into the Tiffin River, a 55-mile-long tributary of the Maumee River. Class B biosolids are applied to farm fields.
During the renovation, D’Ambrosia worked closely with the city’s engi-neering team and with Jones & Henry Engineers of Toledo. Five years ago, D’Ambrosia and his team added two biosolids lagoons, bringing the total to five and providing a year’s storage. In 2013, the facility added an air diffu-sion system to its wet-weather retention lagoon, keeping solids suspended until the water is treated. Last spring, the plant added a larger and more efficient grit removal, washing and dewatering system.
A TALE OF TWO CAREERS
Frank D’Ambrosia’s career in clean water had the most unlikely of starts. Growing up in New York City, D’Ambrosia wanted to be a music teacher. He went to a Catholic high school in Brooklyn, earned a bachelor’s degree in music education from Queens College and got some credits toward a master’s.
“I taught music in the New York school system in the mid-1970s, but after only a year, the city had to lay off 5,000 teachers,” he says. “If you were teaching less than eight years, you got laid off.” Always resourceful, D’Ambrosia formed a five-piece band with some other unemployed teachers. Called Frequency, and later Touch, they played Top 40 songs and covered groups like Steely Dan, Pablo Cruise and Foreigner. D’Ambrosia played the keyboard.
After successful gigs at various New York resorts, the band moved to hotels and lounges along the East Coast, from Boston to Miami. One night, while playing at a bar in Jacksonville, Florida, D’Ambrosia’s future wife, Susan, came in and liked what she heard. Soon the couple started dating. Shortly thereafter, they moved to Defiance, Ohio, her hometown, and D’Ambrosia’s three-year music career ended. He began putting down roots and working at the wastewater treatment plant.
Does he have regrets? “Wastewater certainly has been a good career for me,” D’Ambrosia says. “The more I got into it, the more I saw that there was advancement and that I could make a good career for myself. Plus, you’re doing something that’s good not only for the environment but also for people in the community. Every day you have a chance to learn something new. There’s always something different going on, so yes, I definitely think it’s a good career choice for young people.”
While running the Archbold plant, D’Ambrosia still keeps his musical chops, playing clarinet and saxophone as well as piano. He performs on weekends with community groups, at churches and with the Defiance College Jazz Band.
Frank D’Ambrosia, a former music teacher and traveling musician, has enjoyed a rewarding career and earned an industry lifetime achieve-ment award as superinten-dent at the Village of Archbold Wastewater Treatment Plant.

The project also included modifications to a tertiary lagoon to create an overflow basin that retains diverted influent over 5 mgd.
Today, the plant’s activated sludge process treats an average daily flow of 1.6 mgd and removes 96.8 percent of TSS, 99.1 percent of CBOD, 92.4
percent of ammonia and 90.5 percent of phosphorus. Effluent discharges to Brush Creek, which flows into the Tiffin River, a 55-mile-long tributary of the Maumee River. Class B biosolids are applied to farm fields.
During the renovation, D’Ambrosia worked closely with the city’s engi-neering team and with Jones & Henry Engineers of Toledo. Five years ago, D’Ambrosia and his team added two biosolids lagoons, bringing the total to five and providing a year’s storage. In 2013, the facility added an air diffu-sion system to its wet-weather retention lagoon, keeping solids suspended until the water is treated. Last spring, the plant added a larger and more efficient grit removal, washing and dewatering system.
A TALE OF TWO CAREERS
Frank D’Ambrosia’s career in clean water had the most unlikely of starts. Growing up in New York City, D’Ambrosia wanted to be a music teacher. He went to a Catholic high school in Brooklyn, earned a bachelor’s degree in music education from Queens College and got some credits toward a master’s.
“I taught music in the New York school system in the mid-1970s, but after only a year, the city had to lay off 5,000 teachers,” he says. “If you were teaching less than eight years, you got laid off.” Always resourceful, D’Ambrosia formed a five-piece band with some other unemployed teachers. Called Frequency, and later Touch, they played Top 40 songs and covered groups like Steely Dan, Pablo Cruise and Foreigner. D’Ambrosia played the keyboard.
After successful gigs at various New York resorts, the band moved to hotels and lounges along the East Coast, from Boston to Miami. One night, while playing at a bar in Jacksonville, Florida, D’Ambrosia’s future wife, Susan, came in and liked what she heard. Soon the couple started dating. Shortly thereafter, they moved to Defiance, Ohio, her hometown, and D’Ambrosia’s three-year music career ended. He began putting down roots and working at the wastewater treatment plant.
Does he have regrets? “Wastewater certainly has been a good career for me,” D’Ambrosia says. “The more I got into it, the more I saw that there was advancement and that I could make a good career for myself. Plus, you’re doing something that’s good not only for the environment but also for people in the community. Every day you have a chance to learn something new. There’s always something different going on, so yes, I definitely think it’s a good career choice for young people.”
While running the Archbold plant, D’Ambrosia still keeps his musical chops, playing clarinet and saxophone as well as piano. He performs on weekends with community groups, at churches and with the Defiance College Jazz Band.
Frank D’Ambrosia, a former music teacher and traveling musician, has enjoyed a rewarding career and earned an industry lifetime achieve-ment award as superinten-dent at the Village of Archbold Wastewater Treatment Plant.
‘‘Everybody has a lot of respect for Frank.
If you can’t get along with him, it’s your
problem. Frank fits in with our vision of being
proactive in keeping our wastewater operators
trained and their skills sharp.”DENNIS HOWELL
Pure RecognitionSAN DIEGO PUBLIC UTILITIES PICKS UP HONORS FOR EFFECTIVE COMMUNICATION ABOUT ITS WATER PURIFICATION DEMONSTRATION PROJECT FOR INDIRECT POTABLE REUSE
By Craig Mandli
HEARTSAND MINDS
You could say the San Diego Public Utilities Department started in a deep hole. “Toilet to Tap” was the original negative idea the department was saddled with selling to the public for adding purified wastewater
to the drinking water supply.But a program facelift and innovative community education programs,
all while dealing with severe drought, helped convince residents that waste-water reclamation can be a solution for the area’s water shortage.
In late 2014, the Public Relations Society of America San Diego/Imperial Counties Chapter presented the department with the Edward L. Bernays Silver Award of Merit for Public Affairs for its Water Purification Demon-stration Project public outreach program.
CREATING DIALOGUE
The demonstration project’s goal was to confirm the feasibility of puri-fying recycled water to supplement drinking water supplies. The outreach program for the demonstration project included presentations, booths at community events, facility tours, informational materials, advertisements and social media.
After an outpouring of support, the San Diego City Council unani-mously adopted the project’s findings in April 2013 and set forth directives for implementing the Pure Water San Diego program, which when complete
will divert some 100 mgd from the Point Loma Wastewater Plant to three future water purification facilities. Those plants will treat the water with membrane filtra-tion, reverse osmosis and UV disin-fection/advanced oxidation before delivery to existing reservoirs.
“It was really a comprehensive communication plan and out-reach strategy that encouraged public involvement and fostered active com-munity dialogue,” says Alma Rife, senior public information officer. “The result was an increase in understanding and a general approval rating of water purification that went from 26 percent in 2004 to 73 percent in 2012.”
THE BEGINNING
After several years of study, the council in October 2007 chose indirect potable reuse as the best way to maximize use of recycled water. The coun-cil commissioned the Water Purification Demonstration Project to deter-mine the feasibility of turning recycled water into purified water.
For a year beginning in 2012, the Advanced Water Purification Facility reclaimed 1 million gallons of effluent daily and treated it to a level clean enough to drink. The project included extensive testing at each step of the process, along with a multipronged education program inviting people to take virtual and actual tours of the facility.

‘‘The result was an increase in understanding
and a general approval rating of water
purification that went from 26 percent in 2004
to 73 percent in 2012.”ALMA RIFE
Outreach tools include infographics and handouts on the safety of recycled water and the final report of the Water Purification Demonstration Project.
“City staff participated in a variety of community events, including community street fairs, health fairs and expos, events on college campuses, and events with a focus on the environment and science, such as the annual San Diego Festival of Science & Engineering EXPO Day at Petco Park and Earth Fair at Balboa Park,” says Rife.
“The city also reached out to the multicultural communities at events such as Linda Vista Multicultural Festival, Juneteenth Celebration, Asian Cultural Festival and Fiesta del Sol.”
The yearlong demonstration project included more than 9,000 water-quality tests that determined no contaminants were present in the purified water. The California Department of Public Health and the San Diego Water Board approved the city’s water purification concept.
According to Rife, the city received a positive response from the public at events. “Most people did not have much previous knowledge of purify-ing water, but once the water purification process was explained to them in detail, they are generally supportive of potable reuse,” says Rife. “The public realizes that the city needs a reliable and drought-proof local water supply.”
YOUTH COMPONENT Rife says the city considers educating children at least as important as
informing adults. In her mind, the next generation will make decisions about future water supply solutions and needs information about the long-term benefits of water reuse.
“The city offers free tours of our North City Water Reclamation Treat-ment Plant to Boy Scout and Girl Scout troops, elementary schools and vari-ous youth organizations,” says Rife. “Additionally, the staff participates in events at schools and with youth organizations such as the YMCA. We focus on creating content that involves lots of engagement. This includes hands-on activities, easy-to-understand visuals that are eye-catching, and asking questions to keep their attention.”
That includes answering questions that are not always positive. While people have embraced the idea of drinking recycled wastewater as they receive more information, some adults and children remain skeptical.
Rife says city employees answer the tough questions with transparency and honesty: “If one of our staff members does not know the answer to a question, they take down the person’s contact information and get back to them in a timely manner with an accurate response.”
THE NEXT STEP
In November 2014, backed by the findings of the outreach program, the City Council unanimously voted to advance the Pure Water San Diego pro-gram. The program has support from several environmental groups, city officials and community leaders, many of whom recently served as members of the Pure Water Working Group behind the Water Purification Demon-stration Project.
The immediate goal is the construction of a full-scale purification facil-ity that will process 15 mgd by 2023. By 2035, if all goes as planned, nearly 30 percent of San Diego’s water (83 mgd) will come from local sources or treated wastewater.
Public outreach campaigns will play a large part and include infograph-ics and handouts on the safety of recycled water. “This is a very diverse area, and we can reach a broader multicultural audience by translating materials into additional languages,” Rife says.
“In addition, we plan to increase our audience on all social media plat-forms, seek more partnerships with youth-based organizations, and partner with colleges and universities to offer tours and presentations.” Youth-ori-ented materials will include fact sheets, presentations, activity pages and trading cards. Virtual events such as video contests and social media polls will help educate the tech-savvy crowd.
The city’s outreach program has served as a model to other agencies seeking to implement water purification. Water agencies from as far away as
Japan and Australia have visited to learn more.“We’ve come a very long way from the idea of drink-
ing water from the toilet,” says Rife. “We’ve been proac-tive from the start, and it has paid off. The people here now know that recycled wastewater is a viable and needed remedy for California’s water issues.”

28 TREATMENT PLANT OPERATOR
A California clean-water plant has moved closer to a vision of being off the grid by 2020 through a partnership that now fulfills about 50 percent of its power needs.
Regional Water Recycling Plant No. 1 (RP-1), located in the City of Ontario and operated by Inland Empire Utilities Agency (IEUA), delivers biogas to run a privately owned fuel cell installation, then buys the power at rates below utility grid prices.
The 44 mgd (design) tertiary plant treats an average of 28 mgd. Its efflu-ent, along with that of IEUA’s other three wastewater treatment plants, goes into the utility’s reclaimed water system, where it is used for in-house pro-cesses; for irrigation of parks, golf courses and farms; for industrial purposes; and for groundwater recharge.
Its biosolids system uses three-phase digestion, which provides some 700,000 cubic feet of biogas every day for the fuel cells. The biosolids are trucked to an IEUA composting facility in Rancho Cucamonga that produces more than 230,000 cubic yards of SoilPro Premium Compost per year.
CLEANER ELECTRICITY
IEUA needed a new plan when air-quality regulations required a reduc-tion in output of RP-1’s two 1.4 MW cogeneration engines. While their total
output capacity was the same as the new 2.8 MW fuel cell installation, the agency was limited by emissions standards to operating just one of engines.
The agency decided on a partnership with a private firm, which owns and operates the fuel cell plant and handled its design, financing and con-struction. The system uses a DFC3000 Direct FuelCell power plant from FuelCell Energy, which calls the project the largest digester gas fuel cell installation operating in the United States. It went online in January 2013.
In exchange, IEUA signed a 20-year power purchase agreement (PPA) to buy all the electricity the fuel cells generate. “Most of the biogas is used by the fuel cells,” says Pietro Cambiaso, IEUA senior engineer for environ-mental compliance. “Excess gas is used in boilers to heat the digesters.” Heat from the fuel cells is also recovered.
Switching to fuel cells, which don’t require combustion, greatly reduced emissions:
• Carbon monoxide (CO) by 92 percent• Nitrogen oxides (NOx) by 6 percent• Volatile organic compounds (VOCs) by 91 percent• Sulfur oxides (SOx) by 72 percent• Particulate matter by 86 percent A small amount of gas from the acid phase of digestion is flared because
it is low in heating value and would require substantially more cleanup of hydrogen sulfide and siloxanes than the rest of the digester gas.
NO CAPITAL INVESTMENT
The PPA gives IEUA a set cost for electricity into the future without having to fund the project from its capital bud-get. “There was no capital outlay,” says Cambiaso. “We’re only purchasing the power at an established rate. We didn’t want to assume the risk, so the PPA was a good solution.”
Jesse Pompa, senior associate engineer in environmental compliance, adds that the PPA addresses some issues the agency
had heard of with other projects. “With other agencies, we had seen that the gas conditioning skid and the fuel cells would be from separate manufactur-ers, and there would be a lot of finger-pointing if there was any downtime.
The fuel cells can also be powered with natural gas, in which case RP-1 still pays the guaranteed starting rate for the power: 12.6 cents per kWh with a 2.5 percent annual escalation. That is comparable to the price now paid to Southern California Edison. “The assumption is that Edison’s rates will

increase between 4 and 6 percent based on historical data,” says Cambiaso. “Over time, we’re going to see the savings.”
SUPPLY AND DEMANDRP-1’s electrical demand ranges from 3.5 MW in winter to just above 4
MW in summer. “There is some parasitic load for the 2.8 MW fuel cell plant, so we see a maximum of around 2.4 MW,” says Pompa.
The fuel cells are supplemented by a 4-acre, 800 kW solar array, installed in 2008, that uses both fixed and tracking solar panels. IEUA installed similar
systems at all its locations through a PPA with SunPower, for a total of 3.5 MW solar generating capacity. The solar installations provide 8 percent of the utility’s electrical needs, replacing power previously purchased off the grid.
“We’re still working on implementing some efficiency projects at RP-1 to conserve energy,” says Cambiaso. “Ultimately, the goal is to be self-suffi-cient. We have higher demand in summer, so we need to work on that. In winter, we make some excess power and are working with the local utility to export that power back to the grid.”
At present, biogas generation matches up well with the need for gas on site, but the agency is considering adding gas storage. “The demand may change or the production may change,” says Cambiaso. “So we’re looking to see if it would be cost-effective to add gas storage.”
The gas conditioning system is covered by Inland Empire Utilities Agency’s power purchase agreement.

30 TREATMENT PLANT OPERATOR
Operators and staff of the 1.8 mgd Perryville (Missouri) Wastewater Treatment Facility planted more than 1,400 trees last spring to halt erosion along the banks of the Cinque Hommes Creek, which passes
in front of the plant and is its receiving water.In the bargain, they’re beautifying the landscape. “We sure hope it
works and the trees take hold before a gully washer rain comes along,” says Jeremy Meyer, water and wastewater superintendent at the two-stage trick-ling filter facility. A portion of creek bank near the plant has eroded away at least 10 to 12 feet in the last decade.
AN INSIDE JOB
Using a planting machine pulled by a 108 hp John Deere model 6415 tractor, operators Robert Brown and Dave Myer planted 14- to 16-inch-tall cottonwood, bald cypress and sandbar willow cuttings, spaced 10 feet apart and in rows with 10 feet of separation. Operator Wendell Valleroy drove the tractor.
In eight hours over two days, the men covered nearly 11 acres of field and the embankment near the creek, assisted by Neil Bert, plant operations foreman, and Mike Compte, operator. Meyer used a dibble bar to hand-plant 100 willow stakes on the eroded portion of the stream bank. He plans to plant 300 more next spring. “We are counting on the root structure of the trees to stop the erosion,” says Meyer.
The operators also used a dibble bar to hand-plant 3-foot-tall saplings of pin oak, red oak, shumard oak, white oak, bur oak and black walnut in the
area farther from the creek. “The idea is to have the slower-growing trees mature to provide shade in an area where a planting attempt several years ago partially failed,” says Meyer.
CONTROLLING AN INVASIVE
The idea of planting the trees grew out of a request from the Missouri Department of Conservation (MDC). Staff members spotted the severe ero-sion while surveying the creek for Japanese hops, an invasive species that can quickly choke off a waterway. “I asked them if the hops could be used to make beer,” Meyer recalls jokingly.
The creek empties into the Mississippi River, where the Japanese hop vine is most commonly found. In recent years it has been increasing its range into streams and tributaries. The MDC worked with the city and Meyer to negotiate a cost-sharing agreement that provided 90 percent fund-ing for the nearly $7,000 project. A portion of the funding was to revisit and

Operators and staff of the 1.8 mgd Perryville (Missouri) Wastewater Treatment Facility planted more than 1,400 trees last spring to halt erosion along the banks of the Cinque Hommes Creek, which passes
in front of the plant and is its receiving water.In the bargain, they’re beautifying the landscape. “We sure hope it
works and the trees take hold before a gully washer rain comes along,” says Jeremy Meyer, water and wastewater superintendent at the two-stage trick-ling filter facility. A portion of creek bank near the plant has eroded away at least 10 to 12 feet in the last decade.
AN INSIDE JOB
Using a planting machine pulled by a 108 hp John Deere model 6415 tractor, operators Robert Brown and Dave Myer planted 14- to 16-inch-tall cottonwood, bald cypress and sandbar willow cuttings, spaced 10 feet apart and in rows with 10 feet of separation. Operator Wendell Valleroy drove the tractor.
In eight hours over two days, the men covered nearly 11 acres of field and the embankment near the creek, assisted by Neil Bert, plant operations foreman, and Mike Compte, operator. Meyer used a dibble bar to hand-plant 100 willow stakes on the eroded portion of the stream bank. He plans to plant 300 more next spring. “We are counting on the root structure of the trees to stop the erosion,” says Meyer.
The operators also used a dibble bar to hand-plant 3-foot-tall saplings of pin oak, red oak, shumard oak, white oak, bur oak and black walnut in the
area farther from the creek. “The idea is to have the slower-growing trees mature to provide shade in an area where a planting attempt several years ago partially failed,” says Meyer.
CONTROLLING AN INVASIVE
The idea of planting the trees grew out of a request from the Missouri Department of Conservation (MDC). Staff members spotted the severe ero-sion while surveying the creek for Japanese hops, an invasive species that can quickly choke off a waterway. “I asked them if the hops could be used to make beer,” Meyer recalls jokingly.
The creek empties into the Mississippi River, where the Japanese hop vine is most commonly found. In recent years it has been increasing its range into streams and tributaries. The MDC worked with the city and Meyer to negotiate a cost-sharing agreement that provided 90 percent fund-ing for the nearly $7,000 project. A portion of the funding was to revisit and

AN ILLINOIS WATER TREATMENT PLANT IMPROVES WATER QUALITY AND OPERATIONS WITH A MAJOR UPGRADE AND A TEAM THAT THRIVES ON CHALLENGES
STORY: Trude Witham PHOTOGRAPHY: Stephen Haas
water: PLANTtop performer
OPERATORS AT THE OTTER LAKE WATER TREATMENT Plant have a lot to be happy about — improved water quality and operations after an $8.5 million upgrade, a supportive water commission and general manager Dennis Ross.
Ross brought his operations team through an 18-month improvement project at the plant, in Girard, Illinois. Completed in 2010, it included add-ing solids contact clarifiers, two new multimedia filters, a new control room and laboratory, and a million-gallon clearwell.
In 2013, a UV/advanced oxidation process disinfection system was added to take care of seasonal taste and odor issues. The operators’ learning curve is ongoing. “I’m happy with the length of time these projects took, as it gave the operators time to focus on each new system and provide input,” says Ross. “Throughout construction, the team faced a different daily challenge. They had to keep up with constant changes, but they took it on, and I think they actually enjoyed the challenge.”
The new system is more efficient. “The clarifiers operate without mov-ing parts,” says Ross. “The old system had paddles, chains, gears, shear pins and so on. Our maintenance went from a daily disaster to near zero. The old plant had a small chlorine room that was converted to a lab, but that was also the main plant entrance. So, we upgraded to a new lab with enough room for all the proper equipment we need to perform routine lab work.”
Today, the 3.5 mgd (1.8 mgd aver-age) conventional treatment plant produces finished water with 0.03 to 0.10 NTU and 184 mg/L hardness for 17,000 customers.
MAKING IMPROVEMENTS
The Otter Lake treatment plant and the 765-acre Otter Lake were built in 1969 in response to water short-ages from the City of Springfield, the area’s previous water supplier. The plant is operated by the Otter Lake Water Commission, which serves the communities of Auburn, Divernon, Girard, Pawnee, Thayer, Virden, Nilwood and Tovey, the South Palmyra Rural Water District and Henderson Water.
“None of these towns or districts could afford to have a water plant of their own, so the towns got together in the early 1960s and designed this plant,” says Ross. The commission is run by an eight-member board of direc-tors, one appointed by the leadership of each member community.

The board decided in 2007 to upgrade the water plant to replace aging equipment and accommodate growth. The existing flocculation/sedimenta-tion basins were not automated and were wearing out.
“It was a good system back then, but new regulations required lower tur-bidity, which we had a difficult time meeting,” says Ross. The board hired Hurst-Rosche Engineering to look at equipment options. The commission
chose ClariCone solids contact clarifiers from CB&I for ease of operation and low maintenance. “We visited other plants that were using those and talked to the operators,” says Ross. “We spent a lot of time doing our homework.”
Water from Otter Lake is pumped to the plant where it is fed powdered activated carbon and a preoxidant before entering the head tank for mixing. From there, it enters the ClariCone units (two, for redundancy). Treated water overflows into a weir and is piped to multimedia filters (Leopold - a Xylem Brand). Peroxide is added for advanced oxidation to eliminate taste and odor issues.
The water is sent to the UV system (TrojanUV) and then disinfected with sodium hypochlorite gas before entering the clearwell. “The new clearwell is baffled to meet Illinois EPA contact time requirements before the water is sent to our second clearwell,” says Ross. A MOSCAD SCADA system (Motor-ola Solutions) ties the plant together.
SMOOTH STARTUP
The ClariCone clarifiers provide mixing, tapered flocculation and sedi-mentation in one hydraulically driven vessel. There are no mixers, scrapers, recycle pumps or other continuous moving parts. The system maintains a dense, suspended, rotating slurry blanket that provides solids contact, accel-erated floc formation and solids capture. The conical concentrator maximizes slurry discharge concentration and enables operators to visually monitor the slurry discharge.

top, basically an upside-down cone,” says Ross. “Water comes in the bot-tom, where it is mixed with caustic and polymer, turning at a pretty high rate. As the water makes its way up the cone, the surface is larger, so the water turns at a much slower rate. A blanket is formed in the lower por-tion of the cone, and clean water comes off the top.”
The operators’ learning curve was smooth. “Our lead operator, Jeff Stanley, received hands-on training at another plant, then returned after a week and trained the others,” says Ross.
Bob Dill, operations supervisor, helped ensure a successful startup. “He did his homework, and we tested new chemical feeds in the old plant so we knew what rates we would need to feed,” recalls Ross.
Since the clarifiers need to have a sludge blanket to perform, the opera-tors pumped lime sludge from the old plant into the new clarifiers with a 3-inch trash pump. “When we started up the new plant, the sludge blanket we needed was already in the cones, so we were able to make water that met our permit the first day. This would not have happened without Bob’s up-front work.”
BETTER TASTE
The $2.3 million upgrade to UV/AOP technology allows the plant to com-ply with the Cryptosporidium rule and produces better-tasting water. “We had just gone through about eight months of algae in the lake and were getting calls about taste and odor,” recalls Ross. “We looked at other plants’ UV/AOP systems and talked to operators to find out what they liked and didn’t like.”
Although the new system uses significant electricity, Ross feels it is a better way to reduce taste and odor. “The system looks simple, but there is a whole set of automated controls, separate from the SCADA,” Ross says. “Operators must calibrate the in-line meters and check the sensors as part of the state-required verification process.

WATER BUFFALODennis Ross, Otter Lake Water Commission general manager,
has dedicated his adult life to the water industry. At 17, he began working for Missouri Cities Water Company in St. Charles. After getting his certification, he moved into management and worked for several water systems.
He reached a high point in 2014 when he received the AWWA George Warren Fuller Award from the Illinois Section of AWWA. “I didn’t feel that I was in the same class as others I know who had received this award,” he says. “It was very emotional. Besides my family, the chairman of my board, Jake Rettberg, was there.”
Ross credits his mentors for his success: “My main mentor was the late Max Wells, who was the division manager for the St. Charles division of Missouri Cities Water. I was working as a draftsman, and Max asked if I would like to move to meter reading, which is where everyone starts. Max taught me how to deal with customers and mentored me while on that job.”
Another mentor was Lynn Bultman, vice president of Missouri Cities, who promoted Ross to division manager in Warrensburg, Missouri. “He was willing to put a 29-year-old kid in a manage-ment position, even though everyone else in that operation was older than I was,” Ross says. “I don’t think either of these gentle-men knew they were my mentors, but they enjoyed sharing their knowledge with the next generation, and I was lucky enough to be there to soak it up.”
Today, Ross mentors others: “When I came to the Otter Lake plant, I missed having peers to talk to in a larger water system, so I got involved with ISAWWA.” He ended up chairing the Education Committee and met people from other water plants, helping them with treatment issues. Ross also serves on the Diversity Commit-tee, chairs the Water for People Committee and serves on the Water Utility Council.
His hobby is riding his 2009 Harley Davidson Ultra Classic motorcycle as part of the Water Buffaloes (www.ridewithpurpose.org). He does the annual Ride with Purpose to the AWWA ACE conference to raise money for Water for People. He has ridden to Dallas, Denver and Boston.

Sensors in the reactor tell the system how much power is needed for the correct dose of light. Operators check the sensors monthly by comparing them to three reference sensors kept in storage. Each unit has two reference sensors, which TrojanUV verifies and calibrates yearly.

define the plant operations team. “I believe they’re happy here because they are encouraged to make sugges-tions and to come up with things that are beyond the normal job,” says Ross.
The operators use their talents to everyone’s advantage; they even remodeled the plant’s bathroom. “Moving the lab allowed us to con-vert the old lab into a break area for the microwave, coffee maker and refrigerator,” says Ross. “All of these were in the filter room before. The operators welcomed that change.”
The job offers substantial vari-ety: lab work, maintenance, meter reading, grounds maintenance. Oper-ators also help protect the Otter Lake watershed by planting trees and lay-ing riprap along the shoreline. Otter Lake is the only lake in the state with its own mechanical barge, according to Ross. It can haul 17 tons of riprap and place it along the shoreline at a rate of about 100 feet per day with a crew of three.
The operators support each other, helping new hires understand a treat-ment process or prepare for the next exam. “One thing that really stands out is when someone offers to work a holiday for an operator with young kids,” says Ross. “That shows how much we are like a family here.”
Ross, a commission team member since 1997 and general manager since 1998, holds a Class A water treatment license. Besides Dill (Class A, 16 years) and Stanley (Class A, 17 years), the team includes Rudy Rodriguez, crew foreman (Class D, 18 years); Class A operators Stan Crawford, Otis Foster, Joe Hogan and Tim Walter; Class C operator Eric Walsh; and Brian Durbin.
Customer service representatives Laura Sommerfeld and Andrea Hanney handle tasks that include billing, human resources, public relations, IT, recordkeeping and bookkeeping.
LOOKING AHEADFuture challenges for the Otter Lake team include keeping up with EPA
regulations, fixing line breaks in the aging distribution system and prepar-ing for weather events. An ice storm in the early 1980s knocked out power for three days; the plant now has standby generators. “We also have cots and sleeping bags tucked away, and in the winter we stock canned goods just in case,” says Ross.
More plant improvements are in the works. New high service pumps and two new backwash pumps should be in place by summer 2016. Variable-fre-quency drives will save about $40,000 a year on electricity.
The team will continue its watershed preservation work and community outreach. “We’re very involved with the ISAWWA, and we hosted a plant tour for them in September 2014,” says Ross. The plant also offers tours to local schools: “Even if those students don’t go on to become operators, they may be our customers some day, so it’s important for them to know who we are and what we do.”

Besides Dill (Class A, 16 years) and Stanley (Class A, 17 years), the team includes Rudy Rodriguez, crew foreman (Class D, 18 years); Class A operators Stan Crawford, Otis Foster, Joe Hogan and Tim Walter; Class C operator Eric Walsh; and Brian Durbin.
Customer service representatives Laura Sommerfeld and Andrea Hanney handle tasks that include billing, human resources, public relations, IT, recordkeeping and bookkeeping.
LOOKING AHEADFuture challenges for the Otter Lake team include keeping up with EPA
regulations, fixing line breaks in the aging distribution system and prepar-ing for weather events. An ice storm in the early 1980s knocked out power for three days; the plant now has standby generators. “We also have cots and sleeping bags tucked away, and in the winter we stock canned goods just in case,” says Ross.
More plant improvements are in the works. New high service pumps and two new backwash pumps should be in place by summer 2016. Variable-fre-quency drives will save about $40,000 a year on electricity.
The team will continue its watershed preservation work and community outreach. “We’re very involved with the ISAWWA, and we hosted a plant tour for them in September 2014,” says Ross. The plant also offers tours to local schools: “Even if those students don’t go on to become operators, they may be our customers some day, so it’s important for them to know who we are and what we do.”

40 TREATMENT PLANT OPERATOR
“People like stability and staying at one facility or municipality,” says Drake. “They don’t always want to uproot their lives and their families’ lives for a job.” That makes it all the more critical to hire peo-ple who fit into a succession plan for the long term.
“As we recruit and bring in candidates, we focus on people who want advancement and want to learn more and move up,” says Drake. “That’s important for us to build our succession planning. That’s the best way for this kind of facility.”
Aside from traditional recruitment, the commis-sion looks to local programs to generate awareness of the industry and its facilities. Tompkins Cortland Community College offered a New York State Health Department Water Operator IIA license course in which the Bolton Point system water staff helped teach a section. The students toured the water plant facility and interacted with staff in the laboratory.
A professor from Cornell University brings in students from his environmental engineering course. Earlier this year, he produced a video of the treat-ment plant. Extending and promoting the facility’s activities in the community helps make prospective employees aware of the career opportunities.
PROMOTING INTERNALLY
While Rueckheim stepped in as general manager, the Southern Cayuga commission found a suitable production manager from an internal source. While a leadperson, Joan Foote had been performing some work normally done by the production manager; she was able to transition into that role.
Drake acknowledges challenges in enticing employ-ees to advance through the ranks: “Some people understand that by moving up to a manager level, there is more responsibility to undertake. Sometimes it means being on call and making quick decisions at two in the morning. Some people just don’t want to step up to that level.”
To help promote from within, the Southern Cayuga commission launched extensive supervisory and man-agement training to employees who show interest and potential to become managers or supervisors. In addi-tion, employees receive operational training beyond what is required to maintain their licenses.
“The training and tests taken by our staff is a strong point of the commission,” says Rueckheim. “Employees receive cross-training in other depart-
ments as time allows. We want to develop our staff into leaders.”Since Rueckheim’s appointment as general manager, he and his team
have worked diligently to update facility procedures so that information does more than sit on a shelf. “We took the information out of our heads and put it on paper,” he says. “When someone asks a question, we pull out the man-ual and find the answers. That makes the team stronger and smarter.”
Leaders hope that by creating a plan and cultivating internal candidates, the commission will be able to create a dependable pipeline of leadership pros-pects. Drake observes, “In developing our succession program and manag-ing open recruitment, Bolton Point focuses on people who want to move up. This means making our entire staff the strongest it can be on all levels.”
The succession plan includes methods for identifying talented people who are interested in increasing responsibility.
In 2011, the Southern Cayuga Lake Intermunicipal Water Commission suddenly found itself with open positions for general manager and pro-duction manager.Besides filling those two roles, the commission had to fill the newly cre-
ated positions of assistant distribution manager and assistant production manager at the Bolton Point Municipal Water System. That meant four key leadership positions open.
The commission responded not by rushing to fill the slots but by taking the long view and developing training and succession plans to help ensure a full pipeline of leadership candidates for the future.
ON THE CAREER PATH
The Southern Cayuga commission, based in Ithaca, New York, operates the Bolton Point system, which serves just under 7,000 metered connections in the towns of Ithaca, Dryden and Lansing and the villages of Cayuga Heights and Lansing.
Without a succession plan in place, it was difficult to move existing per-sonnel into the open leadership slots. The Bolton Point system has a staff of 17, including four distribution operators, four water treatment plant opera-tors, instrument and control mechanic operators, water maintenance spe-cialists and a GIS/IT specialist.
The most likely internal candi-date for general manager was Jack Rueckheim, then distribution man-ager and a 33-year employee of the Southern Cayuga commission. However, he felt ill equipped for that role and was focusing on retirement. Still, in 2011, he agreed to step in as general manager for up to five years or until a replacement could be named.
Rueckheim took charge, immediately identifying opportunities to col-lect and standardize information and align training for all staff. “I kind of stumbled into this as a career years ago,” he says. “I never thought, ‘Oh, I want to work in a water treatment facility,’ but it has proven to be solid, dependable work.”
Judith Drake, human resources manager for the Town of Ithaca and the Southern Cayuga commission, agrees that people do not always consider work in water facilities as a career option: “It’s not always a calling one thinks about in high school, but once they are introduced to the occupation, most tend to stay for the long haul.”
RECRUITING CHALLENGES
Drake finds recruiting for the water facility to be a challenge in that many professionals don’t want to jump from one water plant to another. The Bolton Point system advertised nationally for its open positions and received only eight responses.

42 TREATMENT PLANT OPERATOR
AT THE CONTENTNEA METROPOLITAN SEWERAGE District, tailgating doesn’t mean getting together for beer and burgers before a football game. It refers to the informal morning gatherings of the eight-member operations staff before they head out for their daily tasks. Ideas are broached. Solutions discussed. Experiences shared.
“We’re a team,” says Chuck Smithwick, manager of the district, based in Grifton, North Carolina. “Everybody works together. We don’t let any good ideas go to waste.”
Adds Renee Smith, operator in responsible charge, “We’re small. Each day we might be doing something different. You put on whatever hat you need to wear that day.”
The daily exchange of ideas and observations helps because the district is operating a brand-new wastewater treatment plant, the culmination of more than $33 million in improvements and upgrades over the last 10 years, driven by new requirements from state and federal environmental agencies. The result? The district meets all discharge parameters, including nutrient reductions.
STEP UP TO BNR
The Contentnea district serves the communities of Winterville (popula-tion 10,000), Ayden (5,000) and Grifton (2,800). Average daily flow to the 4 mgd (design) treatment plant is 2.14 mgd. Effluent flows into Contentnea Creek, a part of the Neuse River watershed.
In the old days before the improvement project, the district operated a
2 mgd multi-stage aeration-clar i f icat ion facility designed to reduce BOD and TSS and convert ammonia to nitrite in a partial nitrogen removal pro-cess. “Our operators did a fantastic job of making the old plant work, but the flow had gone beyond what the old plant could handle, and it couldn’t meet the new nutrient limits,” Smith says. “It wasn’t designed to do what we needed it to do.”
To meet the tighter nutrient requirements, the new treatment works is anchored by a five-stage biological nutrient removal (BNR) Bardenpho oxi-dation ditch process (Ovivo). The new headworks includes a screen and cyclone grit removal system (Parkson Corp.). The flow then passes through a Parshall flume where flow is monitored.
The headworks is designed for a maximum wet-weather flow of 8 mgd. Smithwick says infiltration and inflow is a problem in the collections sys-

tem. Each community is responsible for the integrity of its own system. “We’re working with our communities on reducing I&I,” Smithwick says.

In the Bardenpho system, the first phase of the oxidation ditch operates in the anaerobic mode for luxury uptake of phosphorus. It is followed by an anoxic zone for nitrogen removal, an aerobic aeration stage for nitrification, a second anoxic stage for further denitrification, and a post-aeration stage to promote settling in the clarifier. Return activated sludge is directed back to both anoxic zones.
Two 90-foot-diameter, 16-foot-deep clarifiers settle solids and produce a clear overflow that passes to a tandem of deep bed sand denitrification filters.
Methanol is the carbon source. The filters are “bumped” periodically to release nitrogen in its gaseous form.
The filter also polishes the wastewater.Filter backwash water is returned to the head of the plant. TSS is not an
issue, as the plant easily meets its requirement of less than 30 mg/L. Total nitro-gen isn’t an issue anymore: In 2014, the plant effluent averaged just 1.69 mg/L total nitrogen. Final effluent is UV disinfected (WEDECO) before discharge.
Biosolids are aerobically digested, gravity thickened to 2 percent solids and dewatered on two new 800 Series incline screw presses (Huber Technol-ogy) rated at 90 gpm. Cake averaging 18 to 20 percent solids is hauled to a compost facility about 90 miles away. The district owns 70 acres surround-ing the treatment plant where liquid biosolids can be applied.

44 TREATMENT PLANT OPERATOR
“We started operating the screw presses in March 2014, with the goal of reducing land application of biosolids to our property by 50 percent,” says Smithwick. “We typically apply about 2.2 million gallons to our fields annu-ally.” In 2014, the property received 800,000 gallons, fertilizing Bermuda grass and coastal hay for livestock feed. Material is applied from mid-March through October. About 1.5 million gallons was dewatered in the presses in 2014.
KEEPING CONTROL
The control system (Ovivo) ramps the aerators up and down to control dissolved oxygen in the BNR process and optimize chemical and energy use.
PLCs on the individual pieces of equipment provide further process control, and the plant uses a telemetry system to oversee all processes and alert oper-ators to an issue if necessary. “The ditch is very operator-friendly,” Smith says. “We essentially turn it on and let it run.”
The new plant capped a 10-year outlay in capital improvements to the treatment system and the wastewater collections system, including intercep-tor and pump station work. Much of the funding came from outside sources and zero- or low-interest loans. About 30 percent came as grants from the U.S. Department of Agriculture and Rural Development and the North Car-olina Rural Center. Other money came from the state’s Clean Water Man-agement Trust Fund. “Without their help, none of this would have been possible,” Smithwick says.
The district bills the communities it serves, and they in turn bill cus-tomers. Smithwick says individual sewer bills have increased slightly, and the communities are implementing flow-based billing over the next two years.
USING THE OLD PLANT
While the former treatment plant is gone, it is not forgotten. In fact, it serves a purpose. The district uses space in the old plant for solids process-ing and storage. “Four of the old circular clarifiers have been converted to aerobic digesters for processing solids,” he says. These small tanks (150,000-gal-lon capacity) have been retrofitted with diffused air blowers. They are used in rotation, week by week.

The CMSD staff includes, front row, from left, Harriett Pridgen, Windy Sammond and Renee Smith; back row, Jimmy Edwards, Stephen Berry, James Woodard and Chuck Smithwick. Not shown: Ricky Barrow. “We pump biosolids into one of the digesters for a week, then switch to
a second digester and pump into that one for a week,” Smithwick says. It’s a batch operation: Each digester holds solids for about a month to condition the material before it is transferred to the dewatering facility or spread on land.
“By using the old plant, we’ve been able to increase our storage from 1 mil-lion gallons to 2.4 million gallons,” Smith-wick says. “From an operations standpoint, we can’t have enough storage space.” The increased capacity enables the plant to remove, stabilize and properly recycle its biosolids.
OPERATING INNOVATIONS
The Contentnea team’s ingenuity has helped the plant perform effectively.
Besides Smithwick and Smith, the team includes James Woodard, Ricky Bar-row and Stephen Berry, operators; Jimmy Edwards, mechanic; Windy Sam-mond, lab assistant; and Harriett Pridgen, administrative officer.
As is typical with new treatment processes, the staff received training from the equipment manufacturers, but Smith and her staff have made their own adjustments to meet their specific needs. “Each facility is different,” Smith says. “We learned the new processes together and we brainstormed with all our operators on how to optimize operations.”
One of the most important lessons learned was that the BNR oxidation ditch system can be most effectively controlled by monitoring dissolved
oxygen entering the second anoxic zone. “The manufacturer gave us the idea, and we’ve learned how to operate with the DO a bit lower and get better denitrification in the ditch,” says Smith. “That means less meth-anol needed in the denitrification filters and less cost. We’ve been able to optimize the efficiency of the deni-trification process.”
Plant operators have made another adjustment that improved phospho-rus removal. “Weather and mixed liquor suspended solids play a big part in phosphorus removal,” Smith says. During summer, the staff main-tains the MLSS at 3,000 mg/L or less and increases the DO content of the basin. In winter, the MLSS increases to about 4,000 mg/L.
“We’ve found the lower MLSS in summer results in better phos-

Besides Smithwick and Smith, the team includes James Woodard, Ricky Bar-row and Stephen Berry, operators; Jimmy Edwards, mechanic; Windy Sam-mond, lab assistant; and Harriett Pridgen, administrative officer.
As is typical with new treatment processes, the staff received training from the equipment manufacturers, but Smith and her staff have made their own adjustments to meet their specific needs. “Each facility is different,” Smith says. “We learned the new processes together and we brainstormed with all our operators on how to optimize operations.”
One of the most important lessons learned was that the BNR oxidation ditch system can be most effectively controlled by monitoring dissolved
oxygen entering the second anoxic zone. “The manufacturer gave us the idea, and we’ve learned how to operate with the DO a bit lower and get better denitrification in the ditch,” says Smith. “That means less meth-anol needed in the denitrification filters and less cost. We’ve been able to optimize the efficiency of the deni-trification process.”
Plant operators have made another adjustment that improved phospho-rus removal. “Weather and mixed liquor suspended solids play a big part in phosphorus removal,” Smith says. During summer, the staff main-tains the MLSS at 3,000 mg/L or less and increases the DO content of the basin. In winter, the MLSS increases to about 4,000 mg/L.
“We’ve found the lower MLSS in summer results in better phos-

ditch is very
operator-friendly. We
essentially turn it on
and let it run.”RENEE SMITH

phorus removal,” Smith says. In hot weather, increased DO reduces the ten-dency of phosphorus to release back into the water. The plant also adds alum during summer to increase phosphorus removal.
PEAK PERFORMANCE
The tweaks make a difference. The district produces outstanding efflu-ent, averaging well under permitted levels for BOD, TSS, phosphorus and total nitrogen. Effluent phosphorus averaged 0.66 mg/L for all of 2014; total nitrogen averaged 1.69 mg/L.
The plant’s nitrogen permit limit is stated in pounds released per year. “Our permit limits us to no more than 37,100 pounds of nitrogen on an annual basis,” Smithwick says. “In 2014, our actual was 10,492 pounds.”
The district has gone from near the bottom of the list to first in nitrogen removal among the mem-bers of the Neuse River Compliance Association, a regional nutrient trading group formed to reduce nitrogen into the sensitive Pamlico Sound estuary.
Before installation of the new treatment processes, the district dis-charged more than 6 mg/L of total nitrogen at the midyear points of 2008 and 2009, and more than 8 mg/L in 2010. In 2014, the midyear number was 1.52 mg/L, lowest in the compliance association. “It’s much easier now,” says Smithwick. “It’s better for our operators and for the environment.”

56 TREATMENT PLANT OPERATOR
IN MY WORDS
Lise LeBlanc started a consulting career 18 years ago, helping farmers in Canada’s Atlantic provinces develop crop management programs.
Along the way, she saw a critical need to manage nutrients on land, “to ensure that we don’t have excessive nutrients leading to environmental issues, or not enough nutrients so that farmers don’t get good crop yields and quality.”
It was then her business, LP Consulting in Mount Uniacke, Nova Scotia, took an additional direction. Today, she helps businesses and municipalities turn organic waste materials into resources and market them, usually as farm fertilizers and soil amendments. She sees big potential for residuals of many kinds, including municipal biosolids, as commercial fertilizers grow more expensive and as the farm community looks to more sustainable practices.
She believes the biggest key to successful farm-based waste-to-resource programs is understanding the market: To be viable, a product must deliver provable economic value and fit in with farmers’ existing practices. LeBlanc shared a broad picture of Canada’s residuals market in an interview with TPO. Many of her insights translate well to biosolids recycling projects.
: What triggered your interest in residuals as a viable product for
farmers?LeBlanc: I’m really interested in the economics of growing crops: How
much money are we putting in, and what are we getting out? It became clear that straight inorganic commercial fertilizers were becoming more expen-sive. Farmers were cutting back. Soil pH and nutrient levels decreased. So I started asking what was out there that could improve my farm clients’ crop production.
: What was your first venture into the residuals area?
LeBlanc: We started with the Brooklyn Power utility here in in Nova Scotia. They were taking wood ash to a landfill and paying a tipping fee. That was very expensive. They were interested in reducing expenses but also in whether this material could be a resource. We did tests on the mate-rial, secured environmental permits and conducted research on 26 farm fields to look at the soil health over time. We found we were increasing yield, improving soil pH and increasing nutrients. I encouraged my farm clients to use the wood ash in their crop production programs. As they saw improve-ments in their fields, neighbors noticed, and it grew from there.
: How exactly is the wood ash beneficial?
LeBlanc: It has a lot of nutrients, in particular potash, phosphorus, sul-fur and calcium. It also acts like lime by increasing soil pH. It was like a huge multivitamin. All of a sudden, farmers were greatly increasing produc-tion at a fraction of the cost of commercial lime and fertilizer. On really poor soils, we more than doubled yield and quality.
: What is the scope of your company’s services on projects like this one?
LeBlanc: We work for the com-pany on testing, permits and regu-latory compliance. We handle marketing, with demonstration sites, booths and farm meetings to make farmers aware. Then we work with the farmers. How much do you need? What’s the best way to use it? Put in front of corn? Apply it in fall or spring? We determine the tonnage to send to each farm and work with truck-ing companies to make sure they deliver on a timely basis. If issues with the public arise, we put on pub-lic meetings and talk to the media.
: Have you been involved
with municipal biosolids projects?LeBlanc: Halifax Regional
Municipality had been putting waste-water sludge into the harbor, which was not acceptable. They looked at alternatives in what they called the Clean Harbor Solution. They decided on an alkaline-stabilization program through N-Viro Systems Canada, which is now owned by Walker Industries.
They approached me for help in working with farmers. I looked at the product analysis and thought it was great. We had nitrogen and phosphorus in the biosolids, high potash from the cement kiln dust, and lime to increase soil pH. We did have pushback from environmental groups and went through our painful years, but now we have a waiting list of farmers. We secured a CFIA (Canadian Food Inspection Agency) label for the product. Because it’s sold as fertilizer, it doesn’t have to follow provincial biosolids guidelines.
: What are some keys to a successful waste-to-resource program?
LeBlanc: It’s important to understand the market. It’s not enough to say your product has N, P and K in it and farmers should take it. The agri-culture community will only embrace a product if there is a good return on their dollar. Take the Halifax product, for example. To buy lime and com-
Lise LeBlanc, with a soil amendment made from alkaline-stabilized bio-solids from the Halifax (Nova Scotia) Regional Municipality.
Residuals as Resources: Knowing the MarketLISE LEBLANC HELPS ORGANIC RESIDUALS SUPPLIERS CONNECT WITH THEIR CUSTOMERS. HER SUCCESS WITH MUNICIPAL AND PRIVATE-SECTOR CLIENTS HOLDS LESSONS FOR BIOSOLIDS RECYCLING PROGRAMS.
By Ted J. Rulseh
mercial fertilizer to replace a tonne of N-Viro product, farmers would have to spend $125 to $150. So if they’re paying $40 to $50 a tonne for the prod-uct, that’s a significant return. It takes somebody to show them that — a lot of presentations and penciling out the economics at the table.
: Apart from pure economics, what factors influence success?
LeBlanc: What’s the soil type in your locality? If farms already have a high soil pH, then an alkaline-stabilized biosolids will not have a market. If the soil already has good organic matter, then organic matter in a compost is not a selling feature. You need to understand the growing season farmers are working with. During peak times when the farmers need the product, you need to have a lot of trucks lined up. Some residuals companies will have just a couple of trucks going. Farmers can’t wait and will just cancel. They’ll apply commercial fertilizer because it’s faster. It’s important to have a good relationship with the farm community. If you don’t have one, work with some-body who does. I recommend finding a local agrologist who is highly respected among farmers — someone who knows what will sell and what won’t.
: How do you recommend approaching community relations?
LeBlanc: The way farmers manage the product is important. You want to reduce neighbor conflicts as much as possible. Make sure you don’t apply it on weekends. Make sure you don’t apply it in the heat of summer when you could generate odors, because odors will shut you down. Instead of hav-ing farmers store material on the fields, ship it when they’re ready to use it. In our programs, once we adopted these practices, essentially 99 percent of calls and concerns stopped. If something does go wrong, deal with it up front. Don’t hide it, because it will come out, and then it’s difficult to get trust back.
One thing most people don’t think about is: Your first face to the public is your truckers. They don’t need to be your PR people, and they shouldn’t be; that’s not their training. But spend some time with them to at least let them know what the product is that they’re hauling. Give them brochures so if someone stops and asks a question, they can say, “This is a biosolids com-post (or whatever it is); here’s some information, and you can call the person listed on the back.”
The key to communication is being honest. I’ve conducted public meet-ings. I prefer one-on-ones because public meetings can be hijacked. Meet one on one with people who have concerns. Provide information. Listen to them. You’ll have those who’ve heard bad things about residuals and aren’t
sure. With information, you can bring them around. You also have those who, whatever you give them or tell them, will never change their minds.
: Besides the products you’ve already mentioned, what other pro-
grams has your company been involved with?LeBlanc: We run a wood ash program for the J.D. Irving forest prod-
ucts company out of New Brunswick. Our wood ash programs are booked now about two years in advance, before the product is even made. We’re look-ing at moving chicken manure and livestock manure that farmers can’t use on their own land. We’re also looking at soil blending and composting.
: What are some other residual products that you see as having
potential?LeBlanc: One is pulp and paper sludge. Some companies try to burn
it, but it has high water content, so that’s very inefficient. Some years ago, a company tried a land application program, but it wasn’t well managed, and odors shut it down. But I’ve seen it on agricultural land, and it works fantas-tic. I think it has big potential.
Fish waste is an excellent source of nitrogen and other nutrients for farms, but again, there’s a need to address odor. You could co-compost it. Biofuel is another potential market for using residuals. To the general public, if they’re uncomfortable with biosolids, if there is an “ick factor,” well, you’re not using it to grow food. You’re using it to grow energy. There’s probably residual material out there that we don’t even know about yet that could be excellent for waste-to-resource programs.
: What’s the benefit of co-composting?
LeBlanc: Co-composting can increase the value of a compost and make it easier to move. Suppose you have a material that has a nutrient value of $5 or $10 per tonne. That’s not going to be very attractive to the farm community. But what if there’s another residuals company nearby that has a different prod-uct, so that if you blended those two together, it’s worth $50 a tonne? Now you certainly can go back to the table and talk about moving that product.
: What are some examples of residuals that could be profitably mixed?
LeBlanc: Adding biosolids to compost can greatly increase the nutri-ent value, but then you have to deal with public concern about biosolids. That’s not difficult in the agricultural sector, but then farmers have to deal with their neighbors. Another material that can be composted is digestate from food waste, or food waste mixed with animal manure.
: How would you characterize the future potential for residuals?
LeBlanc: I think there is huge potential for residuals. The price of fer-tilizer continues to go up. The ability to easily extract phosphorus from the earth is decreasing. In the next 30 years, that phosphorus will be extremely expensive. Phosphorus is key to plant growth, so it’s important that govern-ments support residuals for land application. If we’re to be sustainable in the future, we can’t keep putting these residual nutrients into landfills.
: Can regulatory agencies play a role in advancing residuals
programs?LeBlanc: Departments of environment need to improve their approaches
if we’re to move ahead on these sustainable programs. Many departments say they support sustainable programs, but in reality they make it very dif-ficult. Many don’t like to look at research conducted in other areas. They say, “We’re different here.” But in reality they’re not so different.
Why do we set programs back by decades because their first response is to say no, regardless if there are similar successful programs elsewhere? That’s not supportive of sustainability. I understand they need to ensure that a product is safe, but when they have all the data to show that it’s safe, they shouldn’t put up roadblocks to making programs successful. That’s frustrat-ing for companies that want to provide sustainable programs. It all comes back to sustainability: reducing waste, changing waste to resources and using those resources.

IN MY WORDS
Lise LeBlanc started a consulting career 18 years ago, helping farmers in Canada’s Atlantic provinces develop crop management programs.
Along the way, she saw a critical need to manage nutrients on land, “to ensure that we don’t have excessive nutrients leading to environmental issues, or not enough nutrients so that farmers don’t get good crop yields and quality.”
It was then her business, LP Consulting in Mount Uniacke, Nova Scotia, took an additional direction. Today, she helps businesses and municipalities turn organic waste materials into resources and market them, usually as farm fertilizers and soil amendments. She sees big potential for residuals of many kinds, including municipal biosolids, as commercial fertilizers grow more expensive and as the farm community looks to more sustainable practices.
She believes the biggest key to successful farm-based waste-to-resource programs is understanding the market: To be viable, a product must deliver provable economic value and fit in with farmers’ existing practices. LeBlanc shared a broad picture of Canada’s residuals market in an interview with TPO. Many of her insights translate well to biosolids recycling projects.
: What triggered your interest in residuals as a viable product for
farmers?LeBlanc: I’m really interested in the economics of growing crops: How
much money are we putting in, and what are we getting out? It became clear that straight inorganic commercial fertilizers were becoming more expen-sive. Farmers were cutting back. Soil pH and nutrient levels decreased. So I started asking what was out there that could improve my farm clients’ crop production.
: What was your first venture into the residuals area?
LeBlanc: We started with the Brooklyn Power utility here in in Nova Scotia. They were taking wood ash to a landfill and paying a tipping fee. That was very expensive. They were interested in reducing expenses but also in whether this material could be a resource. We did tests on the mate-rial, secured environmental permits and conducted research on 26 farm fields to look at the soil health over time. We found we were increasing yield, improving soil pH and increasing nutrients. I encouraged my farm clients to use the wood ash in their crop production programs. As they saw improve-ments in their fields, neighbors noticed, and it grew from there.
: How exactly is the wood ash beneficial?
LeBlanc: It has a lot of nutrients, in particular potash, phosphorus, sul-fur and calcium. It also acts like lime by increasing soil pH. It was like a huge multivitamin. All of a sudden, farmers were greatly increasing produc-tion at a fraction of the cost of commercial lime and fertilizer. On really poor soils, we more than doubled yield and quality.
: What is the scope of your company’s services on projects like this one?
LeBlanc: We work for the com-pany on testing, permits and regu-latory compliance. We handle marketing, with demonstration sites, booths and farm meetings to make farmers aware. Then we work with the farmers. How much do you need? What’s the best way to use it? Put in front of corn? Apply it in fall or spring? We determine the tonnage to send to each farm and work with truck-ing companies to make sure they deliver on a timely basis. If issues with the public arise, we put on pub-lic meetings and talk to the media.
: Have you been involved
with municipal biosolids projects?LeBlanc: Halifax Regional
Municipality had been putting waste-water sludge into the harbor, which was not acceptable. They looked at alternatives in what they called the Clean Harbor Solution. They decided on an alkaline-stabilization program through N-Viro Systems Canada, which is now owned by Walker Industries.
They approached me for help in working with farmers. I looked at the product analysis and thought it was great. We had nitrogen and phosphorus in the biosolids, high potash from the cement kiln dust, and lime to increase soil pH. We did have pushback from environmental groups and went through our painful years, but now we have a waiting list of farmers. We secured a CFIA (Canadian Food Inspection Agency) label for the product. Because it’s sold as fertilizer, it doesn’t have to follow provincial biosolids guidelines.
: What are some keys to a successful waste-to-resource program?
LeBlanc: It’s important to understand the market. It’s not enough to say your product has N, P and K in it and farmers should take it. The agri-culture community will only embrace a product if there is a good return on their dollar. Take the Halifax product, for example. To buy lime and com-
Lise LeBlanc, with a soil amendment made from alkaline-stabilized bio-solids from the Halifax (Nova Scotia) Regional Municipality.

mercial fertilizer to replace a tonne of N-Viro product, farmers would have to spend $125 to $150. So if they’re paying $40 to $50 a tonne for the prod-uct, that’s a significant return. It takes somebody to show them that — a lot of presentations and penciling out the economics at the table.
: Apart from pure economics, what factors influence success?
LeBlanc: What’s the soil type in your locality? If farms already have a high soil pH, then an alkaline-stabilized biosolids will not have a market. If the soil already has good organic matter, then organic matter in a compost is not a selling feature. You need to understand the growing season farmers are working with. During peak times when the farmers need the product, you need to have a lot of trucks lined up. Some residuals companies will have just a couple of trucks going. Farmers can’t wait and will just cancel. They’ll apply commercial fertilizer because it’s faster. It’s important to have a good relationship with the farm community. If you don’t have one, work with some-body who does. I recommend finding a local agrologist who is highly respected among farmers — someone who knows what will sell and what won’t.
: How do you recommend approaching community relations?
LeBlanc: The way farmers manage the product is important. You want to reduce neighbor conflicts as much as possible. Make sure you don’t apply it on weekends. Make sure you don’t apply it in the heat of summer when you could generate odors, because odors will shut you down. Instead of hav-ing farmers store material on the fields, ship it when they’re ready to use it. In our programs, once we adopted these practices, essentially 99 percent of calls and concerns stopped. If something does go wrong, deal with it up front. Don’t hide it, because it will come out, and then it’s difficult to get trust back.
One thing most people don’t think about is: Your first face to the public is your truckers. They don’t need to be your PR people, and they shouldn’t be; that’s not their training. But spend some time with them to at least let them know what the product is that they’re hauling. Give them brochures so if someone stops and asks a question, they can say, “This is a biosolids com-post (or whatever it is); here’s some information, and you can call the person listed on the back.”
The key to communication is being honest. I’ve conducted public meet-ings. I prefer one-on-ones because public meetings can be hijacked. Meet one on one with people who have concerns. Provide information. Listen to them. You’ll have those who’ve heard bad things about residuals and aren’t
sure. With information, you can bring them around. You also have those who, whatever you give them or tell them, will never change their minds.
: Besides the products you’ve already mentioned, what other pro-
grams has your company been involved with?LeBlanc: We run a wood ash program for the J.D. Irving forest prod-
ucts company out of New Brunswick. Our wood ash programs are booked now about two years in advance, before the product is even made. We’re look-ing at moving chicken manure and livestock manure that farmers can’t use on their own land. We’re also looking at soil blending and composting.

58 TREATMENT PLANT OPERATOR
Phosphorus can be a challenge not only in clean-water plant effluent but in biosolids. For facilities looking to land-apply biosolids in areas with naturally phosphorus-rich soils, high P in the material can be an obstacle.
Now, Renewable Nutrients, based in Pinehurst, North Carolina, offers a process that can remove phosphorus from the solids and capture it down-stream. The results are crop- and soil-friendly biosolids and a granular cal-cium phosphate product that can be used as fertilizer.
The Quick Wash process chemically separates phosphorus from the bio-solids in one tank, then chemically precipitates it in another tank. The com-pany offers a mobile, trailer-mounted pilot treatment unit that can be installed at clean-water plants to test how the process could be configured to operate at a commercial scale on the site.
Jeff Dawson, CEO, and Larry Sandeen, chief engineer, talked about the process in an interview with Treatment Plant Operator.
: What need in the marketplace drove development of this
technology?Dawson: Around the country and the world, there is an issue with the
amount of phosphorus being land-applied with biosolids. Excess phosphorus can run off into waterways and cause algae blooms. On the other side, the world
has reached its peak in extraction of phosphorus, a nonrenewable resource that is also essential to growing food. Our technology creates biosolids with a more desirable nitrogen-to-phosphorus ratio while capturing the extracted phosphorus in a product that can be directed to other beneficial uses.
: How is the phosphorus extracted from the biosolids stream?
Sandeen: We acidify the solids to a pH of roughly 2.5 to lyse some of the cells, dissolve the phosphorus and make it available to be carried for-ward in a liquid stream through a separation process. There we capture the low-phosphorus solids, which can be land-applied without affecting surface waters. The low-pH, high-phosphorus liquid moves to another tank.
: How is the phosphorus recovered from that liquid stream?
Sandeen: We add lime to that liquid to a pH of about 10.5, causing cal-cium phosphate solids to precipitate out. After another separation process, the high-pH, relatively clean liquid stream can be returned to the treatment plant headworks or to a point in the process that requires alkalinity. The precipitated solids can then be processed further — concentrated, dewatered or dried, depending on the intended use and the specific market we would be delivering the product to.

By Ted J. Rulseh
TECHNOLOGYDEEP DIVE
1) Biosolids are pumped into Tank 1 and acidified to lower the pH, thus solubilizing the phosphorus.
2) Low-pH material is pumped through a ceramic membrane, allowing only liquid and solubilized materials to pass.
3) Low- or no-phosphorus material is pumped to dewatering.
4) Solubilized phosphorus solution passes through mem-brane and is pumped to Tank 2.
5) Lime is added to the phosphorus-rich solution in Tank 2 to raise the pH and precipitate the phosphorus.
6) A second ceramic membrane separates the precipitated phosphorus from the liquid stream, allowing phosphorus-free liquid to pass, and leaving behind extracted phosphorus.
: Where in a wastewater treatment plant process would this pro-cess be deployed?
Sandeen: Most commonly, it would be installed before sludge dewa-tering. Our system could function as the thickening process. It could also be implemented on a phosphorus-rich sidestream. There are ample opportuni-ties to customize it to the specific needs of a facility.
: What is the typical solids content of the biosolids created from
this process?Sandeen: We typically target about 4 percent, but it depends on how
we apply the technology. That’s one reason we have our pilot plant — so we can look at different plants, different scenarios, different points in the pro-cess to pull the sludge from. You can work this process with digested biosol-ids, waste activated sludge or almost any solids stream.
: How would you describe your pilot unit?Sandeen: It’s a trailer-mounted unit that we can move from location
to location to demonstrate the technology. It receives flows on the order of 3 to 5 gpm. The point is to model the extraction process on site and collect data that will inform full-scale implementation. We can also collect samples of the two solids streams and send them to dewatering vendors to see how their equipment would handle the materials. For an existing facility consid-ering a retrofit of our process, we can send samples to the manufacturers of the dewatering equipment they currently use to get an assessment of how operations would be affected by our process.
: What degree of phosphorus removal can your process achieve?
Dawson: We can customize the amount of extraction depending on what the customer wants the solids to look like on the back end. So if you need a 2-to-1, 3-to-1 or 4-to-1 nitrogen-to-phosphorus ratio in your biosolids because in your region that’s what you need for land application, we can do that. We have a technology that extracts more than 80 percent of phospho-rus, but that can be dialed down if the customer so desires.
: What does this technology look like in terms of the equipment
deployed on a site?Dawson: We’re agnostic in terms of the equipment that’s needed. Cus-
tomers don’t buy a “black box” from us. They buy the technology, and all the parts along the chain are off-the-shelf, proven technologies that have been around the waste treatment business for quite some time. We’re agnostic in how we put a process together to meet the needs of a facility.
: What are prospective customers saying about this technology?
Dawson: As we have conversations with consulting engineering firms and end users, there are dynamic discussions about changing how the indus-try deals with nutrient issues and nutrient extraction and how this could be a game-changing technology. There’s a need for it because states are getting much more restrictive in the land application of phosphorus in biosolids. And the reality is that as a society we have to start reusing phosphorus as that resource becomes scarcer and prices continue to go up.

60 TREATMENT PLANT OPERATOR
Scott Meyer was stuck. An increase in material volume at his Idaho septage dewatering plant, along with tighter regulations on the clean-liness of land-applied biosolids, left him struggling to keep up. That’s
when he took matters into his own hands.“Our screening system was constantly plugging with hair and rags, and
having to stop periodically to clean it meant I couldn’t filter septage at the volume I needed to,” says Meyer. “I started tinkering with my own design, and that’s how Screenco Systems was born.”
Meyer’s high-capacity Dual Screen System, which made its commercial debut at the 2015 Water & Wastewater Equipment, Treatment & Transport (WWETT) Show, is constructed of aluminum with stainless steel screens, with a collection sump and a high-capacity 6-inch drain. The system has two 3/8-inch gapped stainless steel bar screens at opposing angles; the front screen is virtually self-cleaning. It is a non-mechanical, simple way to remove large pieces of trash, rocks and other debris from the flow stream.
“It’s really a simple design with no moving parts,” says Meyer. “When the septage is pumped in, trash and debris hits the deflector and ends up on the bottom of the screen. Once it starts draining slower, the operator manually rakes it clean.”
This unit has a 4-inch telescoping inlet hose that moves laterally and can be connected to a vacuum truck or other flow stream. The system is porta-ble; and the 19.5 square feet of screening area allows for continued use and is easy to rake clean to the garbage drain tray. It can treat over 500 gpm. Var-ious screen gap sizes are available.
The unit can be mounted above an open-pit settling pond or as a stand-alone application that can be stationed almost anywhere. The station is eas-ily cleaned with water; catwalk access enables easy cleaning and raking. The
filtered garbage that collects atop the screens can be raked into a wheel-barrow or other collection device. The unit comes with a stainless steel rake.
“We built and tested multiple designs, and have been beta testing this current version in commercial applications for the past 18 months,” says Meyer. “We use it every day at our dewatering plant, and we’ve seen cleaner biosolids, faster off-load times and improved productivity. We’ve run 35,000 gpd through our screen, and the biosolids are virtually garbage-free.”
While he’s been to several past WWETT Shows, the 2015 show was Mey-er’s first as an exhibitor. He says his goal was simply to introduce the indus-
try to his product. “We aimed this system at people like me — private contractors who do their own dewa-tering and small municipalities that dewater as part of their pretreat-
ment,” he says. “I’m hoping to show them that there is a product out there that is simple and affordable. Judging by the positive reaction, a lot of guys have been dealing with the same issues I was.”
Meyer was excited by the response and sold several units while on the floor. He’s already thinking about WWETT 2016 and promises to be back with a “bigger and even better” dual-screen design.
“I have a couple upgrade ideas, including adding forklift skids to make the station more portable,” he says. “The guys I talked with at WWETT told me it was a great design at a good price. Hearing that kind of feedback is exciting!” 208/790-8770; www.screencosystems.com.

Scott Meyer was stuck. An increase in material volume at his Idaho septage dewatering plant, along with tighter regulations on the clean-liness of land-applied biosolids, left him struggling to keep up. That’s
when he took matters into his own hands.“Our screening system was constantly plugging with hair and rags, and
having to stop periodically to clean it meant I couldn’t filter septage at the volume I needed to,” says Meyer. “I started tinkering with my own design, and that’s how Screenco Systems was born.”
Meyer’s high-capacity Dual Screen System, which made its commercial debut at the 2015 Water & Wastewater Equipment, Treatment & Transport (WWETT) Show, is constructed of aluminum with stainless steel screens, with a collection sump and a high-capacity 6-inch drain. The system has two 3/8-inch gapped stainless steel bar screens at opposing angles; the front screen is virtually self-cleaning. It is a non-mechanical, simple way to remove large pieces of trash, rocks and other debris from the flow stream.
“It’s really a simple design with no moving parts,” says Meyer. “When the septage is pumped in, trash and debris hits the deflector and ends up on the bottom of the screen. Once it starts draining slower, the operator manually rakes it clean.”
This unit has a 4-inch telescoping inlet hose that moves laterally and can be connected to a vacuum truck or other flow stream. The system is porta-ble; and the 19.5 square feet of screening area allows for continued use and is easy to rake clean to the garbage drain tray. It can treat over 500 gpm. Var-ious screen gap sizes are available.
The unit can be mounted above an open-pit settling pond or as a stand-alone application that can be stationed almost anywhere. The station is eas-ily cleaned with water; catwalk access enables easy cleaning and raking. The
filtered garbage that collects atop the screens can be raked into a wheel-barrow or other collection device. The unit comes with a stainless steel rake.
“We built and tested multiple designs, and have been beta testing this current version in commercial applications for the past 18 months,” says Meyer. “We use it every day at our dewatering plant, and we’ve seen cleaner biosolids, faster off-load times and improved productivity. We’ve run 35,000 gpd through our screen, and the biosolids are virtually garbage-free.”
While he’s been to several past WWETT Shows, the 2015 show was Mey-er’s first as an exhibitor. He says his goal was simply to introduce the indus-
try to his product. “We aimed this system at people like me — private contractors who do their own dewa-tering and small municipalities that dewater as part of their pretreat-
ment,” he says. “I’m hoping to show them that there is a product out there that is simple and affordable. Judging by the positive reaction, a lot of guys have been dealing with the same issues I was.”
Meyer was excited by the response and sold several units while on the floor. He’s already thinking about WWETT 2016 and promises to be back with a “bigger and even better” dual-screen design.
“I have a couple upgrade ideas, including adding forklift skids to make the station more portable,” he says. “The guys I talked with at WWETT told me it was a great design at a good price. Hearing that kind of feedback is exciting!” 208/790-8770; www.screencosystems.com.

Scrapers clean solids from intake system
ProblemBackwash strainers at a wastewater treatment plant in Toronto, Ontario,
Canada, were consistently clogging with oversized solids that made it past the intake bar screens. Downstream pumping equipment experienced high failure rates, and subsequent treatment stages were overwhelmed.
SolutionThe plant installed two 16-inch Automatic Scraper Strainers from
Acme Engineering Products, rated for 6,000 gpm each. The scrapers use aggressive brushes that clean out the slots of the wedge-wire screen. They operate automati-cally, using line pressure to inter-mittently purge accumulated solids. Maintenance is infrequent and requires simple replacement of the scraper blade and brush.
RESULTThe plant has more uptime
as the strainers effectively remove large solids, and downstream treatment equipment operates within normal parameters. Maintenance is reduced on related equipment in the pumping system. 518/236-5659; www.acmeprod.com.
Biosolids treatment system saves significant costs at naval station
ProblemThe U.S. Naval Air Station (NAS) Jacksonville in Florida needed to
meet the U.S. Navy’s aggressive energy reform targets.
SolutionNuTerra’s detailed financial analysis compared the base’s aerobic diges-
tion operating data to BCR Environmental’s CleanB system. NuTerra installed a unit to treat waste activated sludge from the clarifier to Class B standards before dewatering; the final product is suitable for land application.
RESULTThe project delivered
$75,000 in energy savings, a 95 percent reduction in energy for biosolids treat-ment, and a total operating cost savings of $105,000. Payback on equipment is projected at five years (six and a half years including installation). Pro-jections indicate a reduction in greenhouse gas emissions of 480 tons annually. Improved dewatering reduced the total biosolids volume by 12 truckloads annually, saving more than $10,000 per year in hauling costs. Polymer consumption was reduced by 71 percent. 904/819-9170; www.bcrenv.com.
Thickening centrifuge operates more efficientlyand in a smaller footprint
ProblemThe Kenosha (Wisconsin) Water Utility Wastewater Treatment Facility
faced a decision to repair an aging dissolved air flotation treatment (DAFT) system or move forward with emerging sludge thickening technology.
SolutionKenosha installed the
Centrisys THK 200 Thick-ening Centrifuge. The unit uses a smaller footprint and can be easily installed in a 1,000-square-foot building. Its enclosed process nearly elimi-nates odors. It produces mate-rial at 5 percent solids and has the capability to produce 7 per-cent solids. The thicker sludge improves digester operation and produces more biogas. It requires minimal operator oversight and less maintenance.
RESULTThe system, in place for three years, uses no polymer and saved
$80,000 to $100,000 in pump and equipment upgrades. Electricity con-sumption is low, as it incorporates a 10 hp feed pump, a 50 hp main drive and a 20 hp scroll drive, all tied into variable-frequency drives. The city installed a second THK 200 for primary sludge thickening to improve digester performance. 262/654-6006; www.centrisys.com.

Fine bar screen removes high amount of solids from headworks
ProblemThe Andover (Kansas) Wastewater Treatment Plant serves a commu-
nity of 12,000 next to Wichita. The original plant was built in 1977 and upgraded four times. In 1993, a coarse bar screen with 3/4-inch bar spacing was installed at the headworks. By 2012, the plant began investigating fine bar screens for greater solids removal.
Solution“The best kind of process improvement is one that pays for itself,” says
Brian Walls, wastewater superintendent. “In this case, the ongoing cost of cleaning the aeration basin, removing rags from diffuser tubes, unclogging return activated sludge pumps and improving the overall performance of the process had an obvious payback cal-culation.” The city selected the Enviro-Care Flo-MultiRake Fine bar screen with 1/4-inch bar spacing.
RESULTThe plant staff estimates the new
screen is removing two and a half times more solids than the old coarse screen. “We had specified the bar screen to be a turnkey, plug-and-go setup,” says Walls. “When we got it, it was. We did the install ourselves and had an electrician run the conduit and wiring to code. The control panel was preprogrammed and only needed minor adjustments. The bar screen fit perfectly in the pre-existing channel.” 815/636-8306; www.enviro-care.com.
Dewatering press produces drier cake solids, runs more efficientlyProblem
The Chestnut Ridge Area Joint Municipal Authority in New Paris, Pennsylvania, required an upgrade from an aging belt press. High opera-tion and maintenance requirements had to be as low as possible to keep life cycle costs down, and dry cake solids were critical to reducing disposal expenses even as plant throughput rose.
SolutionDoug Vitovitch, chief facility operator, personally sourced and super-
vised the installation of a Volute ES302 following the results of a free pilot study. PWTech and local representatives from EnviRep included all necessary pumps and poly-mer preparation equipment, and provided both remote and on-site installation assis-tance to enable Vitovitch to complete the entire munici-pal project from project inception to installation and successful startup in just over six months.
RESULTChestnut Ridge began realizing immediate operational cost sav-
ings as the Volute press can run unattended while producing drier cake than the old belt press. The 2 hp unit uses significantly less power and wash water. The first two-hour maintenance is scheduled for February 2020, if needed. 443/648-3300; www.pwtech.us.

70 TREATMENT PLANT OPERATOR
Screw press helps plant add efficiency to dewatering process
ProblemFor years, the Williamson (New York) Wastewater Treatment Plant had
placed anaerobically digested biosolids from a contact stabilization treat-ment process into two drying beds or four reed bed lagoons. Typically, every five to seven years the town would allow the reed beds to dry and remove the deposited solids via shovels into trucks. The material was unloaded and bulldozed into the nearby property the plant owned. This was time-con-suming and labor-intensive, and rain made matters worse. There was also concern about damaging the liners during the operation. Plant leaders decided on a permanent dewatering operation and in the short term hauled the dewatered material to a composting facility in nearby Ontario, New York.
SolutionBDP Industries con-
ducted on-site demonstrations with its belt press and a screw press. For financial and opera-tional reasons, town leaders chose the screw press. To save on installation costs, the unit was skid-mounted with all accessories and piped and wired at the BDP factory. The press offers a small footprint, low operation labor and expected lower maintenance costs due to few moving components.
RESULTThe 12-inch-diameter screw press has met performance expectations.
Throughput averages 25 gpm at an average of 2.15 percent influent solids concentration, representing 260 pounds per hour of dry solids. It produces a cake averaging 17.3 percent solids. Williamson is now exploring its own composting operation. 518/527-5417; www.bdpindustries.com.
Screw press helps dewater biosolids quickly
ProblemThe wastewater treatment plant in the Town of Middlebury, Indiana,
treats an average daily flow of 0.99 mgd. The plant had been using beds of pea gravel to dry biosolids. This process yielded biosolids at 5 to 8 percent solids but was proving labor-intensive, costly and time consuming with the increasing plant flows.
SolutionThe plant installed a Schwing Bioset Screw Press, selected by
the town and a consulting engi-neer after it outperformed other equipment pilot trials. The feed pump draws material from the aerobic digesters and feeds it to the screw press under low pres-sure. A simple control system allows unattended operation, and the resulting cake exceeds 19 percent dry solids.
RESULTThe press has improved operations and accommodates increasing
plant flows by allowing the plant to quickly dewater the material with less labor, reduced odors and lower hauling costs, all within a smaller footprint. 715/247-3433; www.schwingbioset.com.
Dewatering system decreases energy demand
ProblemA septage dewatering facility in California wanted to become more
energy-efficient. Facility leaders decided to replace an aging vacuum filter, which had a high energy demand and required significant time and expense to keep operating.
SolutionThey chose a 20-foot dewatering drum
from In The Round Dewatering. A cement pad was poured outside the building under a roof overhang, which allows dewatering to take place outside. The process is similar to a gravity dewatering box, as with the box the material must be mixed with a polymer to achieve the waste stream floc. The inside of the drum is lined with interlocking PVC tiles. The difference is that once the drum is full, it rotates one turn every two hours, allowing all free liquids to filter out over-night. The drum is mounted on a roll-off frame and can be loaded on a roll-off truck for transport to the landfill. Once unloaded, it can be washed out quickly with a garden hose and is ready to be filled again.
RESULTThe facility can dewater 20,000 to 24,000 gpd with virtually no
maintenance. The 1/4 hp motor creates large energy savings and elimi-nates the diatomaceous earth used in the old process. 317/539-7304; www.itrdewatering.com.

Reverse aeration evens out temperature differentials
ProblemThe City of Arlington, Washington, population 18,000, shifted its bio-
solids process to composting from land application to produce compost for city road improvements, ball fields, parks, a cemetery and a community gar-den. The challenge was to keep target temperatures within best manage-ment practice (BMP) range in the face of variable moisture content in the dewatered cake arriving at the facility, and variable moisture content in wood waste used as an amendment.
SolutionArlington installed an Aeration Static Pile System (ASP) from
Engineered Compost Systems (ECS). The system has automatically reversing aeration for primary and secondary composting and a biofilter to control odors. The facility produces eight batches of compost mix each weekday, or 40 batches a week, for a total of 2,100 cubic yards per year. Roughly 70 percent of the bio-solids (800 cubic yards) are processed into Class A Excep-tional Quality compost. The process takes five to six weeks.
RESULTThe reversing aeration
system allows the operator to better control temperature and odor. Operator Kevin Bleeck says his ideal mix is 2 yards of biosol-ids cake, 3 yards wood waste and 2.5 to 3 yards of compost overs (larger wood particles that remain after product screening, providing porosity and a source of carbon). 206/634-2625; www.compostsystems.com.

The AS950 sampler controller from Hach Company features a full-color, 2 1/2- by 3-inch display for intuit ive, single-screen programming, USB drive compatibil-ity, error alert and sta-tus screen to simplify troubleshooting in waste-water treatment.
Single-screen program-ming eliminates the need for scrolling through the menu, says Jamie English, product manager, Hach Company.
“The other benefit is the status screen,” she says. “If you want to know what’s going on with the sampler — has it missed any samples, when’s the next program going to start — all you have to do is hit the status button and all that information comes up.”
Logged data such as sample history, cabinet temperature and sen-sor measurements can be downloaded directly from multiple samplers onto a USB drive, eliminating the need for special cables or having to carry a laptop to sampling locations in inclement weather.
The USB port also enables users with multiple samplers to program one sampler, download the settings to a flash drive and upload it to the next controller, eliminating the need to reprogram each sampler.
“It saves a lot of time when you have the same program on multi-ple samplers,” she says.
The AS950 works with existing Hach sampler bases and bottle con-figurations. It includes connections for several digital Hach sensors, enabling pH samples to be taken at the discharge site or when levels reach designated setpoints. Digital sensors can also measure rate of flow.
The high-speed, dual-roller sample pump has a 3/8-inch I.D. by 5/8-inch O.D. pump tube and flow rate of 1.25 gpm at 3 feet vertical lift. Sample intervals can be set in single increments from 1 to 9,999 flow pulses or 1 to 9,999 mins in one-minute increments.
The memory stores up to 4,000 history entries for sample time stamp, bottle number and sample status, up to 325,000 entries for selected measurement channels and 2,000 events.
Optional IO9000 input/output modules can be used to set up relays and alarms that can be set for system diagnostics and logging, such as program end, sample complete, missed sample and full bottle.
The compact, portable sampler, designed for use in 18-inch man-holes, can also be used to measure stormwater runoff and pretreatment by industrial users to ensure permit requirements are being met. 800/227-4224; www.hach.com.

The mROY series of metering pumps from Milton Roy is the little pump that can. Featuring a design life of 20 years, the low-maintenance pumps are available in PVC, PVDF, 316 stainless steel and alloy 20 with flow rates from 0.017 to 170 gph.
“While improvements have been made over the years with various mate-rials, advanced casting technologies, coating systems and control inter-faces, the pump has at its core the dependable design that the industry relies on,” says Jim Carling, global product line manager for Milton Roy.
Applications include the injection of coagulants, flocculants, filter aids, pH control chemicals, chemicals for taste and odor control, dechlo-rination and disinfectants such as sodium hypochlorite in the municipal water treatment process.
Weighing about 65 pounds, the pump is 8 inches wide, 12 inches deep and 18 inches high (including motor).
Key features include a hydraulically balanced diaphragm with a 96,000-hour design and turndown ratios up to 100-to-1 for a full range of adjust-ments based on plant treatment requirements.
“Most diaphragm pumps used in water treatment, or even peristaltic pumps, are pressurized on one side, or in the case of a tube, on the inside,” he says. “On the outside or backside of the diaphragm it’s atmospheric. So the diaphragm or tube is containing all of the pressure. With the hydraulically balanced diaphragm you have the process fluid on one side and hydraulic fluid on the other. So the diaphragm is balanced between two pressurized fluids. It’s under very low stress. You’re not stretching anything. You’re not compressing anything. All you’re doing is flexing a piece of Teflon.”
Other features include powder-coated housing for corrosion resistance, plus/minus 1 percent accuracy regardless of pipeline pressure fluctuations, separate or com-bined capacity adjustment for maximum turndown and fine-tuned control from SCADA sys-tems or other process signals.
Depending how the pump is used, Carling recommends annual mainte-nance of the wetted parts, primarily the check valves and diaphragm.
“Many people can go years without main-tenance, it really depends on the service,” he says. “Is it operating 24/7? Are there a lot of particulates in the pump that are being pumped where it might cause wear? Annual maintenance is always recommended as a preventive, but the diaphragm will last about 10 years.”
Pump options include motors and variable-speed drives based on system requirements and installation condition, electronic capacity adjustment for remote control and advanced technology diaphragm leak detection system.
“It’s really a unique item in the world of industrial products,” Carling says of the pump. “Its fundamental design has been around for many years, and yet, the mROY continues to evolve and is still an innovative technology.” 215/441-0800; www.miltonroy.com.

In Decatur, TX, Wastewater SuperintendentJoe Guinn and his team are dedicated to the efficient operation of the city’swastewater treatment plant. He’s proud of his crew, and the hard work they put in every day at their 700,000-gpd facility.“I have the best operators in the state ofTexas,” said Joe.
According to Joe, one of their facility’s greatest sources of pride is thecondition of their filter belt press. “It takes a good operator to keep abelt press as clean as ours,” he praised. While proper maintenance iscritical, so is timely replacement of filter belts due to their inevitablewear and tear. “When we needed a new belt for our filter press, youguys [at USABlueBook] were right on top of it. You got us exactly what we needed, in no time at all.”
