Power Plant: Proceed With Care

I read with interest your editorial on renewable energy (“You Operate a Power Plant,” TPO, February 2013). We have undertaken many initiatives at the Western Monmouth Utilities Authority’s Pine Brook Treatment Plant to address energy conservation.

We have done the obvious such as lighting retrofits, motion detectors to shut off lights in vacant buildings, installing energy-efficient electric motors and variable-speed drives where feasible, and fine-tuning process controls. In addition, we contracted with a third party to install a 0.8 MW solar field on the plant site.

They own the system for 15 years, and we purchase the generated power at a reduced rate from what our local power supplier charges. After that, we own the system. Since we are a government agency and were not eligible for credits, the contractor received them, enhancing the economic viability from their perspective. We also entered into a power purchase agreement with another third party, again buying electricity at a reduced rate.

The authority has also extensively explored using digester gas to operate a combined heat and power (CHP) system. This has not yet proven to be a positive from an economic standpoint, as the payback period appears to be too long.

While there is an obvious advantage to generating your own power in this manner, there can also be negatives besides the economic aspect. If you decide to enhance gas production in your digestion system, you may have to construct, operate and maintain a receiving station for grease or whatever else you decide to add to the digesters.

You also may have to truck material to your facility, which in our case means through residential neighborhoods. Odors and spills are a real possi-bility leading to potential complaints from the public.

As stated in the editorial, methane gas must be conditioned before it is burned in an engine or fuel cell, and this leaves a waste for disposal in some manner. Maintenance and downtime also should be factored into the analysis.

We took all of this into consideration and decided not to move forward on a CHP project at this time. Yes, a third party can be used to construct and operate a CHP system, but it has to be economically viable for them, as well. I am aware of a couple of wastewater facilities in New Jersey that have installed and are operating CHP systems, but my take is that they may have been more interested in being “green” than in having a reliable, economical operation.

With regard to wind power, again it may not be a viable option for everybody. A neighboring authority may spend as much in the end on legal fees fighting the neighboring town’s objections to installing a large wind turbine on the plant site as the actual installation was projected to cost. My point is that whatever you decide to do, make sure you do your home-work thoroughly and get the buy-in of all the affected parties before making a commitment.

14 TREATMENT PLANT OPERATOR

STEPPING UPThe plant is successful largely because of the staff’s caliber. “None of

them came from a wastewater treatment background,” says Pendleton. “One came from a large retailer, two others from a maintenance background, and the other three from factories. We look for responsibility and a good work ethic. We can teach wastewater operation or lab technique, but we can’t teach character. Each person brings that with them the first day.”

Williams came from a manufacturing background, and received his Grade III certification after joining the plant in 2007. “He’s developed into a real asset, capable of performing practically every task we have here,” says Pendleton. “When Albert suggested training someone to help with the NPDES laboratory analyses, Ryan was the natural choice.”

Operator trainee Victory joined the plant as a maintenance employee and handled all the plant maintenance for 10 years, adding biosolids and farming. When maintenance and land application became too much for one person, Tatum took on maintenance.

“Nick was already a journeyman pipefitter and had some mechanical aptitude, and more important, he displayed the ability to take on responsibility and was self-motivated,” says Pendleton. Tatum handles as much maintenance as he can and coordinates the rest with utility machinists, electricians, SCADA and PLC experts, and the vehicle mechanic.

“A lot of mentoring is going on at the plant,” says Pendleton. “When we hired Ronnie Edmondson in early August 2012, we asked Ryan to take responsibility for training Ronnie to do lab work, plant operation and land application. Ryan has done the job very well, and it allowed him the opportunity to be a mentor.”

MUTUAL SUPPORT

Pendleton is modest about why he won the Oper-ator of the Year and Hatfield awards: “I am fortunate to be surrounded by good people. I am supported by my supervisors and the plant’s staff. I think I won because the people here do such a great job.”

He credits Solberg with much of his success: “Albert and I share the load of directing day-to-day operations, and developing strategy for the future. That includes workload scheduling and deciding when and where to apply biosolids. Our mutual sup-port provides stability to the operation that carries over to the team.”

Teamwork and the ability to meet a challenge head-on are other reasons for the plant’s success. In summer 2011, seven scrapers in the plant’s two clari-fiers became badly worn and needed replacing. “As a team, we discussed whether to contract the work out or tackle it ourselves,” says Pendleton. “We opted for the latter.”

They planned the installation for July and August when low flows and minimal rainfall allowed one clarifier to be offline. “We had to coordinate how quickly to drain the clarifier, as doing it too fast would have over-whelmed the return activated sludge pumping system,” says Pendleton.

They drained it over a day and a half, overlapping all shifts. The staff also made sure replacement scrapers were on hand. They emptied and washed the clarifier, inspected it for defects, and made sure a crane and operator were available. The utility’s machine shop inspected the work before the clarifier was placed back in service.

MOVING FORWARD

Beyond operating the plant and the farm, the team has helped enhance the local environment. “We’re one of the last undeveloped properties in Nashville, and we have all kinds of wildlife: deer, wild turkeys, bald eagles and a variety of waterfowl,” says Pendleton. “The fact that we operate a suc-

“We look for responsibility

and a good work ethic. We can

teach wastewater operation or

lab technique, but we can’t teach

character. Each person brings

that with them the first day.”JAMES PENDLETON

DOING IT ALL “We have specialists on staff, but all operators can perform every job,”

says Pendleton. “An operator may perform plant operations today, and tomorrow be land-applying, working in the lab, or doing groundswork and painting.”

Everyone is cross-trained, according to lead operator and laboratory manager Albert Solberg. “They all have to learn how to run digester samples in the lab. After a little training, they pick it right up.”

Pendleton, who has been with the utility for 26 years, 12 at the treatment plant, holds a Grade IV wastewater license and Grade II wastewater collec-tion and water distribution licenses. Solberg has been with the plant for 10 years and holds a Grade IV wastewater license. His duties include overseeing

NPDES permit tests, and he developed the plant’s labo-ratory quality assurance/quality control program from the ground up. Other staff members are:

• Operators Ryan Williams (5 years, Grade III) and Chris Maheu (7 years, Grade IV)

• Operator/maintenance worker Nicholas Tatum (2 years, Grade III)• Operator trainees Jimmy Victory (12 years), Cody Raley (one year) and

Ronnie EdmondsonWilliams assists with NPDES laboratory analyses. Maheu serves as the

wastewater treatment plant safety coordinator, maintaining Material Safety Data Sheet (MSDS) fi les for the entire facility, including the lab. He also con-ducts monthly safety meetings. Operator trainees are involved in land appli-cation. The staff members are encouraged to attend biosolids conferences and learn as much as possible about the subject. They also take seminars and courses, such as activated sludge and basic math.

: Can you give an example of what servant leadership looks like?Hardeman: Last summer, one of our team members, John Baze, had

been out mowing and came to me unhappy. I asked why. He said, “It’s this mower. You say you like this place looking like a campus, nice and mani-cured, but with this mower, I can’t do it. One blade is scalping and the other is raised too high. As much as I try, I can’t adjust it.” We had some money left over from a project, so I asked Ken Komiske, our utilities director, for $7,000 to buy a new mower. He said, “No problem.” So I told John and Mike Bates, our chief operator, to go to the John Deere dealer and pick out the mower they wanted. John is happy now, riding his new mower.

: How do you avoid the common manager’s tendency to lose touch

with the staff members’ day-to-day challenges?Hardeman: I spend most of my Fridays out in the field, talking and

working with my staff. I still come in and operate a shift about once a quarter so I can keep myself informed on what’s going on, instead of just sitting in my office and not being a part of what they’re doing. It’s easy to become com-placent. I try to get involved and stay involved, so when they tell me about situations, I can relate.

One of the biggest lessons I’ve learned is about bridge building — building relationships and keep-ing them open. That includes relationships with supervisors in other departments in the city. It doesn’t matter what department you work for — if you need help, you should be able to call another department. I tell the team here: Never burn a bridge with anybody in the city because you never know when you’re going to have to cross that bridge.

: How would you describe the culture you’ve

helped create at your facility?Hardeman: Our culture comes down to five val-

ues: Humble, teachable, available, flexible and adapt-able. One thing I have learned is that if you have people with good values, you can teach them any-thing. Now when we hire, we look for those values in people. When we sit down for an interview, we bring a piece of paper with the values printed on it. We see if we can see those values in the people applying for the job. If someone has experience in the field, we look at that, but we’re more interested in values. Our last three hires were based on those values, and the people we got are awesome.

: How did you get involved in leadership

development at the association level?Hardeman: At an Oklahoma Water and Pollu-

tion Control Association Short School, a few of us who came up through the operator ranks to become supervisors were talking about our challenges as managers. We discovered that none of us had received any formal management training.

So we decided that for the Short School last October, we would set aside one whole morning for leadership training. We invited Fred Kreiss, a leader-ship training instructor from Severn Trent Services, to share his expertise. He did an excellent job. I did a short presentation on some things I had learned as a leader. The attendees really enjoyed the program. From now on, we’re going to offer leadership train-ing on the last morning of every Short School.

: Where do you look for advice and inspira-

tion as you look to improve as a leader?Hardeman: My inspiration started with my family and my faith. Years

ago, my mom inspired me to become the man I am today. My wife Antoinette believes I can accomplish anything I put my mind to. I draw inspiration from the men and women I work with.

I read a lot of articles about leadership on Yahoo Small Business — arti-cles like “Eight Traits of an Extraordinary Boss,” or “Ten Signs You’re a Hor-rible Boss.” My favorite movie when it comes to leadership is Mel Gibson’s “We Were Soldiers.” You look at the main character’s leadership style and see how his men follow him through battle — it’s incredible. He knew them per-sonally and prayed with each one of them, and he knew what was going on with their families. When it came time to make decisions in the middle of battle, he stepped forward, assessed the situation, and made the call. I’ve watched that movie probably 15 times.

IN MY WORDS

It’s tough making the move from clean-water plant operations to manage-ment. Many who take that step have to learn leadership skills on their own, by trial and error. That was the case for Steven Hardeman, plant superintendent in Nor-

man, Okla. He went to work in waterline maintenance for the city in 1984, moved to the wastewater treatment plant three years later, and worked up the ranks to lead operator, supervisor, and ultimately his current position, which he assumed in 2010. On the way, he struggled with the transition from team member to team leader.

He now wants to do his part to make life easier for his eventual succes-sors and for operators across Oklahoma who aspire to more responsibility. He earned a Master of Business Administration (MBA) degree from the Uni-versity of Phoenix and reads widely about leadership. He has also worked with the Oklahoma Water and Pollution Control Association, and plans to work with the Oklahoma Water Environment Association, to build the begin-nings of leadership training programs.

In addition, Hardeman led the development of the City of Norman Lead-ership Council, with a mission “to provide managers with the skills to lead their teams to higher productivity and personal development.” Hardeman talked about his experiences growing into leadership, and about the leadership principles he puts to work, in an interview with Treatment Plant Operator.

: For you, what was it like making the transition to leadership?

Hardeman: Essentially I was told, “We’re going to make you the super-visor — there’s your office.” Now what? I knew I had to make the plant oper-ate, but on the management side, what was I going to do? I knew I needed to make the work schedule and approve staff members’ vacations and sick leave. Other than that, I had no real clue what I was supposed to be doing. I even-tually called my former boss at his new job and asked him.

: What was the hardest part about becoming a leader?Hardeman: Leading people I had worked with for many years. I had

been their buddy and friend, and now I was their boss. I had to figure out how to maintain good relationships with people who once were my peers — in fact, two of them used to be my boss. I love a quote from Vince Lombardi: “A leader can never close the gap between himself and the group. If he does, he is no longer what he must be. He must walk a tightrope between the con-sent that he must win, and the control that he must exert.” That is so true.

A leader also has to play multiple roles in talking to people. I have to

change in and out of talking to them as a boss, as a friend and sidekick, as a coach, counselor, teacher and visionary. As a confidant and listener, as a soldier working in the trenches with them. As a shield — taking the brunt of things coming at them from every direction. Once I sat and wrote them all down, and I came up with 29 roles a supervisor has to fulfill.

: How did you deal with having to lead people with whom you used to work as equals?

Hardeman: Number one is constant prayer and my faith. Number two was to figure out how to make us one uniform team. When I first became a supervisor, I asked our plant superintendent at the time, “What is our mis-

sion here?” I thought that if I could use our mission state-ment to direct what we did, maybe that would give us a foundation.

It turns out we have a twofold mission: Provide the safest, highest-quality effluent, and do so at the lowest cost to our citizens. I thought maybe I could take that and build a program around it — this is what we do, and here’s what everybody’s role is. I began to talk about our

mission, taking the focus off of me and putting it on what we were doing. When I asked someone to do something, I made sure they understood it as part of our mission — not something they had to do because Steve said so.

: That issue aside, how did you approach leadership?

Hardeman: I had to figure out how to lead people — how to deal with their situations, how to talk to different people. How do you deal with some-one who has a problem at home and has brought that to work and can’t per-form on the job? Or what about a guy who’s coming in late all the time? How do you correct that behavior and make him a productive team member with-out breaking his spirit? It’s a matter of being in the business of restoration, not waiting to fire them. I am in the business of helping people understand what their roles are and what is required of them to make us successful. As far as I’m concerned, writing people up for discipline should be the last resort.

: What is your core philosophy about leadership?

Hardeman: I believe Biblical principles, such as servant leadership, can work in the workplace: I’m a servant leader to my staff. I had to determine what the team members’ skills sets were and what I needed to give them to make them successful. Jackie Crumrine, our human resources development coordinator, said that “as supervisors, we need to give our people the time, the tools and the training to do their jobs.” If I don’t do that, then I have failed them as a supervisor.

Building Better LeadersSTEVEN HARDEMAN BELIEVES NEWLY APPOINTED SUPERVISORS SHOULDN’T HAVE TO LEARN LEADERSHIP SKILLS THROUGH THE SCHOOL OF HARD KNOCKS — HE CONSIDERS TRAINING ESSENTIAL.

“Our culture comes down to five values: Humble, teachable,

available, flexible and adaptable. One thing I have learned is that if

you have people with good values, you can teach them anything.”STEVEN HARDEMAN


Three years ago, an energy audit of the Freeport (Maine) Waste-water Treatment Plant found many ways to save energy by upgrading old equipment, changing processes and insulating

the building. Now the Freeport Sewer District is saving more than $90,000 in electricity and $25,000 in heating oil annually.

To serve a population of 8,300, the district operates a secondary treatment facility and maintains 18 miles of gravity pipes, 11 miles of force main and 11 lift stations. The treatment plant has three inde-pendent trains, and operators can divert water to as many trains as necessary. The 0.75 mgd plant treats 0.350 mgd on average. Effluent discharges to the Harraseeket River, home to one of the richest clam beds in New England. Biosolids are co tourists,” says Leland Arris, general manager. “No one wants to fish, swim or boat in a bad river. There are 24 lobster families and 60 clamming families who work on the river. We affect a lot of people if we have a negative effect on the river.”

Over the last few years, the district has renewed its emphasis on out-performing state requirements. The outfall is in the river estuary, and with clam digging in that area, the district maintains a close relation-ship with the state Department of Marine Resources, which regulates the distance from the outfall at which clammers are allowed to dig.

ASSESSING ENERGY

In 2010, the Woodard & Curran engineering firm conducted a plant energy audit and power assessment. Brian Cataldo, project engineer, proposed several efficiency upgrades to Arris, who was chairman of the wastewater board at the time. They included an aer-ation upgrade that would cut electrical costs in half.

“When I saw that the project would save us more than $80,000 annually, it caught my eye,” Arris says. “That’s like two years of sav-ings in user rate increases of 4 percent. We didn’t have to raise rates

for two years because of that savings, even with significant improve-ments in staffing and operations.”

The plant was built in 1974 with coarse-bubble diffusers. The upgrade separated sludge pumping from aeration and retrofitted fine-bubble diffusers to improve efficiency and save energy. The proj-ect also added hybrid positive displacement blowers (Aerzen) with premium efficiency motors (WEG) and variable-frequency drives (Allen-Bradley/Rockwell Automation). The updates, completed in January 2012, saved an average of 70,000 kWh per month, or about $100,000 per year. Full payback is expected in eight years.

About one third of the $950,000 project cost was funded by a grant from Efficiency Maine, an independent trust that promotes energy efficiency. The district borrowed the remainder from bonds through the Clean Water State Revolving Fund (SRF).

The new aeration system required a learning curve for plant superintendent Dan Bicknell and the operating team. “With the old system, there was no technology — we just turned the blowers on full speed,” Bicknell says. “It was easy to operate, but we didn’t get great results. Now we can measure and balance our units for opti-mum operating conditions. We have data trending and more testing available to us.”

Console effluent thermal heaters allow employees to adjust temperature and humidity in their offices.

The upgrade separated sludge pumping from aeration. The elec-tric sludge pump retrofit has led to significant electricity savings.

The upgrades included hybrid positive displacement blowers (Aerzen).

HEATING WITH EFFLUENTAnother upgrade was an effluent thermal system. Effluent moves

through two heat pumps. Then heated or cooled water is diverted through piping to the district office buildings. Consoles in the offices allow employees to adjust temperature and humidity. “Originally we didn’t agree to the project because it was a high capital investment,” Arris says. “But then we saw it would save an incredible amount of money on heating oil. We have eliminated a $25,000 heating oil bill every year. Plus, we are reducing our carbon footprint significantly.”

The new heating system, which went online December 2011, cost $170,000 and was funded by SRF bonds. Full payback is expected in about seven years.

Woodard & Curran’s analysis also looked at insulation and other upgrades to the process building envelope. Spray foam insulation was added to the roof and other areas. A new room for the biosolids dewatering centrifuge was built with a heat recovery ventilator so that when odors and air are blown out, the heat is captured before it is exhausted.

The insulation and heat recovery projects cost $80,000, funded partially by a grant from the American Recovery and Reinvestment Act of 2009 and SRF bonds. The improvements save $6,000 per year in electricity.

The savings from the aeration upgrade gave the district board confidence to approve the additional proj-ects in a short time frame, says Arris: “We were able to move quickly on other proj-ects that continue to save us energy.”

Joe, the chief plant operator at the city’s wastewater treatment plant, was perplexed. After numerous adjustments to the aer-ation system and batch times, the facility continued to strug-gle with nitrifying.

Since the nitrification process was inhibited, the facility was not meeting its state effluent total nitrogen permit limit of 3.0 mg/L. Joe decided to ask other surrounding operators for their opin-ion and advice. One of these operators recommended Joe contact the Lab Detective.

PLACE TO START

The detective’s first communication with Joe was in a short phone conversation about the plant and its location. It seemed the facility was not far from where the detective was at the time, and he could pay a visit. During the drive, he thought of possible issues that cause poor nitrification:

• Low dissolved oxygen (DO) levels• Low alkalinity and pH levels• Too short of an oxic retention time• Too low MLSS amounts and short sludge age• Liquid temperatures too high or too low

• Rapid liquid temperature change (temperature shock)• High influent ammonia/ammonium concentration• Toxic material in the influent Remembering that nitrification is the conversion (or oxidation)

of influent ammonia/ammonium to nitrite, then to nitrate by nitrify-ing bacteria with sufficient dissolved oxygen and alkalinity, this list seemed like a pretty good place to start once he arrived.

To remove the oxidized nitrate nitrogen from the wastewater, facultative anaerobic bacteria are used to convert the nitrate to nitro-

gen gas in a reduction process where no free dissolved oxygen is present, normally in an anoxic basin or anoxic time cycle during a sequencing batch reactor (SBR) treatment batch. The facility seemed to be having trouble in the oxidizing part of nitrogen removal. The detective also went over the plant information Joe had given him:

• A two-tank SBR, design flow 1.1 mgd• Three positive-displacement blowers (Figure 1)• Influent ammonia concentration of 30 mg/L as N• Influent alkalinity of 270 mg/L as CaCO3

• Influent pH of 7.5• Mostly domestic wastewater from residential users

SURPRISE ON THE WAY All this information seemed pretty normal for wastewater —

nothing seemed out of the ordinary. However, the Lab Detective should have expected the unexpected.

Once the detective arrived at the plant site, Joe gave a brief tour. The SBR plant was about 15 years old — an above-ground system made of porcelain-coated metal plates bolted together. Each SBR tank could hold 550,000 gallons and operated on a timed batch cycle, each cycle being 6.0 hours long. Out of the total batch time, more than 2.0 hours were being devoted to aeration (oxic time). Since the plant had strict total nitrogen permit requirements, complete biological nitri-

fication and denitrification were essential. Joe and the Lab Detective looked over the last year’s lab data,

process control testing results and design drawings. Joe described the operational difficulties during the past year to year and a half. It seemed that as time went on, he couldn’t get enough air as dissolved oxygen (DO) into the basins. Trending data confirmed that over time, the total standard cubic feet per minute (SCFM) output from the blowers had increased, yet the actual DO seemed to be staying constant. Joe estimated that he had tripled the react fill time over the

It seemed that as time went on, he couldn’t get enough air as dissolved oxygen (DO) into the basins. Trending data confirmed that over time, the total standard cubic feet per minute (SCFM) output from the blowers had increased, yet the actual DO seemed to be staying constant. Joe estimated that he had tripled the react fill time over the

Joe, Bill and the detective began digging in one of the brown patches,

noticing that the soil was warm to the touch in the cool spring air.

After digging about 3 feet down, as they neared the 10-inch ductile

iron pipe, the hissing sound of escaping air was apparent.

last few months, and only then would he see the DO increasing near the end of the 180 minutes of total aeration.

CHECKING THE AIR

So, the emphasis of the troubleshooting was placed on the aera-tion system. Joe and the detective went over the aeration system thoroughly, checking blower maintenance records, SCFM gauge accuracy, actual blower RPM (using a tachometer), and bearing heat signature (using infrared thermography). Joe’s maintenance of the facility was exceptional, and that included the aeration system. Noth-ing seemed to be amiss. Even the DO meters used for process con-trol testing were examined as a possible cause for under-aerating.

Attention next pointed to the influent wastewater stream and its oxygen-demanding components. Joe’s regulatory permit required 24-hour composite sampling of the influent and effluent every week. The automatic composite samplers (Figure 2) normally initiated the sampling events at midnight of each Tuesday, ending that Tuesday evening at 11:59 p.m.

Several times, the sampling event would be disrupted, and Joe would collect the samples on a Wednesday or Thursday. These addi-tional sampling days provided useful data, since the Lab Detective could see what the influent characteristics were like on days other than every Tuesday. Again, he struck out — there was nothing unusual in the incoming waste stream:

• Average BOD5: 120 mg/L• Average TSS: 135 mg/L• Average ammonia (NH3) as nitrogen: 30 mg/L• Average nitrite/nitrate nitrogen: 0-2 mg/L

ANSWERS IN THE EARTH

Joe and the Lab Detective took a break and chatted about the long winter they had just come through and how springtime was progressing. The trees were full of budding leaves, flowers were blooming, the grass was sprouting and giving the plant grounds a nice green color.

Joe mentioned that it takes a lot of work to keep the plant grounds looking good, and that an aesthetically pleasing plant is a sign of a well-run plant, at least in the eyes of the state inspectors. One of the shift operators, Bill, had joined the conversation. As he poured himself a cup of hot coffee, Bill remarked that the grass always grows well around the plant, except for the patches behind the SBR tanks. Joe and Bill spoke for a moment about getting some sod to fill in the dead spots.

The imaginary light bulb that appeared over the Lab Detective’s head was enough to light the whole room! “What exactly are you talking about?” he asked. Joe explained that for the last several years, they’d had trouble with what he thought were nematodes or some other soil organism eating the roots of the grass in places around the SBR tanks.

“Darndest thing,” Joe said. “They appear about every 20 feet or so around the back side of the plant. Can’t get the grass to grow there anymore.” Joe and the detective took a walk to get some fresh air and check out the bare spots in the yard. The detective stepped away for a moment to get a better look from above, climbing the plant stairs and accessing the catwalk that circled the round SBR tanks.

From above, he could plainly see the brown patches of dirt that Joe said would not support grass. He quickly rejoined Joe on the ground and asked, “Have you ever experienced problems with the aeration header piping?”

Joe thought for a moment, then recalled about one to two years ago he had to replace a few gaskets in the piping joints that dry-rot-ted and were leaking air near the blowers. At once, he understood why the detective asked the question: “Well I’ll be! Let me get a shovel!”

MAKING THE FIX

Joe, Bill and the detective began digging in one of the brown patches, noticing that the soil was warm to the touch in the cool spring air. After digging about 3 feet down, as they neared the 10-inch ductile iron pipe, the hissing sound of escaping air was apparent.

Joe was relieved and excited to finally locate the source of the missing cubic feet of air. Joe and Bill used the infrared thermography tool to get some temperature readings of the soil along the route of the underground aeration header pipe. Sure enough, there was a marked increase in the soil temperature every 20 feet.

Joe immediately initiated repairs to the piping by excavating the places where the joints were located, replacing the joints’ dried-out rubber-gasket mechanical joints with pipe repair clamps. Joe knew this was a temporary fix, but due to the depth of the pipe, the man-power and available parts, he chose the repair clamp method. He also made long-term plans to replace the clamps or to modify the entire piping system in the future. There were four excavations to be made, two for each SBR tank. After several days, the repairs were complete.

Once the repairs were made to the aeration piping, the plant’s nitrogen removal ability was restored. Joe was able to reduce the aer-ation times of each SBR batch while still maintaining regulatory com-pliance for biological nitrogen removal — and, in the bargain, save a few dollars on the energy bill at the end of the month!

observe and weigh it. The challenge was fi nding a way to do that safely.In discussions with the plastic modular block manufacturer, the plant

team found that 12 pounds of active biomass per cubic foot was the recom-mended limit if the blocks were to deliver 20 years of service. Since each block measures 4 feet long, 2 feet wide and 1 foot high (8 cubic feet), the rec-ommended weight limit was 96 pounds.

The manufacturer’s representative knew of no block hoisting and obser-vation devices, but the Corning team decided to go forward and see if they could open the “black box” for more effi cient process control.

The Corning trickling fi lter consists of a 90-foot-diameter concrete tank with an 8-foot, 6-inch sidewall depth, buried with 2 feet exposed above grade. With the media block joints staggered in six 1-foot layers and the whole resting on 8-inch-high supports that create an underdrain, the 6 feet of media stacks roughly to grade level.

In October 2001, operators pushed a 1 1/4-inch PVC pipe through the center of one of the top blocks and then weaved through it, to the four cor-ners, a 3/16-inch stainless steel cable. They brought the ends together to wrap the block’s rectangular shape, creating a four-point connection for a balanced lifting point.

A small self-standing davit crane with hand winch, mounted at ground level just outside the trickling fi lter tank wall, hoists the test block. The vari-able-frequency-driven motor that rotates the distributor arm is turned off or slowed down to allow plenty of time to remove the block from its position safely and without interfering with the arm.

When the media block is hoisted, the exposed undersides look nothing like the barren top surface of the trickling fi lter, which is exposed to sun, weather and hydraulic pounding from the distributor arm’s discharge.

The active biomass reveals its color, texture and density, and the porosity of the block’s passages is observable. Scrapings of the zoogleal fi lm for micro

LOOKING SHARPThe team members at the City of Corning treatment plant take

pride in their facility, keeping the lawn mowed and windows washed outside and equipment clean and well-maintained inside.

The plant serves a rural community whose biggest employer is Corning Inc., a company chief operator Alan Bontorno calls “a great neighbor.” The company’s headquarters and the Corning Museum of Glass are located in the city.

At the treatment plant, infl uent arrives through three main trunk sewers and feeds into two channels. Water passes through auto-matic 1/2-inch bar screens (E&I Corp.) and then through aerated grit chambers with grit elevators (Siemens Water Technologies/Envirex).

The fl ow then enters a common well from which three Yeomans Chicago Corp. centrifugal pumps (Grundfos) lift it 27 feet to two rectangular primary clarifi ers. From that point, the fl ow is by gravity.

Primary clarifi er effl uent fl ows to a trickling fi lter with plastic media and a motor-actuated rotary distributor arm (Siemens) that provides BOD and TSS removal and nitrifi cation. The next step consists of 10 submerged rotating biological contactors (SRBCs) from Siemens/Envirex.

From the SRBCs, the fl ow proceeds to a fi nal clarifi er (Polychem Systems) and then is discharged to the Chemung River. No disinfec-tion is required; the river travels 20 miles before reaching the City of Elmira, which draws drinking water from the stream.

On the solids side, slough off of fi xed-media bacteria is piped to the primary clarifi ers, and from there, solids are drawn off and fed to an anaerobic digester. Digested material is dewatered to 20 percent solids on a belt press (BDP Industries).

“We run the belt press twice a week and load up 6.5 tons of wet solids per load, or about 13 tons per week,” says Bontorno. “We move more than 100 dry tons of biosolids out of the plant per year.”

Bontorno and his team are preparing for future permits from the state Department of Environmental Conservation with tougher nutrient limits, since the Corning plant lies at the headwaters of the Susquehanna River system, which empties into Chesapeake Bay.

“If we’re required to denitrify, we’ll have to put in an additional process, probably some sort of fi ltration, and they’ll probably also require UV disinfection,” Bontorno says. Phosphorus limits are also in the offi ng.

Meanwhile, operators keep the plant looking sharp. “The belt press is a good example,” says Bontorno. “An engineer who visited here looked at it and said, ‘Do you use that thing?’ I said, ‘Yes we do.’ We hose it down and clean up after every session.” Team members keep track of maintenance tasks on a simple wall chart and use fi le cabinets for maintenance histories. With a bit of diligence, the system works well.

scopic examination are available from the lifted block, the sides of neighbor-ing blocks, and the tops of the layer of blocks below. Observations made in this way result in standard operational responses:

Heavy white gel-like streaks with a black underlayer located mostly in the media crevices indicate Beggiotoa on a septic anaerobic layer, and the response is to increase fl ushing.

Clumps of lint-like masses on otherwise nearly clean media walls indicate fi lter fl y larvae grazing on biofi lm, and the response is to fl ood the fi lter.

Smooth, consistent biofi lm indicates a healthy condition, and the response is to continue monitoring.

MANAGING BY WEIGHT

A spring scale is used between the hoist and the test block to reveal the weight of this fi rst-stage (top layer) trickling fi lter biomass. A new block (dry) weighs 25 pounds. With active biomass growth, the Corning team has seen the test block reach close to 140 pounds, and the growth weight likely would have continued higher. After experimenting with various fl ushing proce-dures, they established a fl ushing program that maintains the block regularly at under 100 pounds.

The fi rst graph bar (Chart A, Week 1) represents the new block with har-ness, wet with wastewater but no biofi lm. It registered under 30 pounds. Allowed to grow without interference, the test block climbed past 130 pounds by Week 15.

To release the weight of the excessive biomass, and to test the adherence of the biomass to the plastic media, the staff took a fi re hose to the test block as

it rested in the trickling fi lter bed (Chart A, Week 16). With repeated weighings, they found that only a forceful stream would dislodge the fi lm growth.

Though this process reduced the weight, it caused signifi cant wear and tear on the plastic modu-lar skin, including some broken seams and folded edges. Again left undisturbed, the test block biofi lm grew back at almost double the startup rate, reaching 110 pounds in fi ve weeks (Chart A, Week 22).

Since the trickling fi lter was not designed with recycling, the team experimented with options for increasing the fl ow to the fi lter. Only a heavy fl ow, along with slowing the distributor arm, effectively sloughed down the biomass. The team proved this by capital-izing on wet-weather events as the source for increased fl ow.

The heavy zoogleal mass that sloughed off during wet-weather events followed the standard path from trickling fi lter effl uent through the SRBC tanks and settling out in the fi nal clarifi ers, after which it was pumped to the primary tanks to resettle.

In trying to short-circuit the solids settling process, they found that open-ing the two 8-inch tank drain valves at the head of the SRBCs captured a good portion of the settleable solids coming out the trickling fi lter (allowing them to settle directly in the primary tanks) while the recycled fl ow increased the stream at the head of the plant enough to effectively fl ush the trickling fi lter. By August 2002 (Chart B, Week 13), the team had a system that worked well.

The temperature of the wastewater was also tracked, as fi xed-fi lm pro-cesses typically bulk up and slim down as the biological entities’ metabolisms shift with the seasons. But as operators took control of the feed and fl ush set-tings and events, temperature infl uence became insignifi cant.

Once a week, the motorized trickling fi lter arm is turned down to its min-imum speed (5 Hz), and the SRBC drain valves are opened for one hour of fl ushing. Bacteria and advanced organisms (such as fl y larvae) slough down in the fi rst few minutes of fl ushing, and the Imhoff cone settleable solids readings jump from typical 2 to 5 mL/L to 175 to 200 mL/L.

Today, trickling fi lter BOD reduction remains constant, and occasional odor problems have been eliminated with operator control and response based on routine media observation and weighing.

CONSISTENT RESULTS

Corning operators now realize highly consistent treatment conditions in the trickling fi lter and expect the plastic media to reach or exceed their 20-year life expectancy. The more operators understand how fi xed biofi lms grow and respond to stimuli, the better they can maintain treatment effi ciency.

The principle espoused by the Corning team is that fi xed-fi lm sys-tems can and should be biologically operated — not just “run.”

When Clean Water Services wanted to expand wastewater treatment capacity in the West Basin portion of its service area in Oregon, offi cials estimated the cost at $30 million.

However, with the vision and collaborative planning of professionals in several departments, the agency met the capacity goal, saved $18 million, and improved the community appeal of the treatment facility in Forest Grove.

“By building a natural system to do our fi nal treatment, we saved millions of dollars and enhanced a prized community asset at the same time,” says Bill Gulacy, plant manager of the Forest Grove Facility. The 90 acres of con-structed natural wetland is part of the existing 748-acre Fernhill Wetlands, owned by Clean Water Services. Already a world-renowned destination for birdwatchers and nature lovers, it is designed to cool and remove nutrients from up to 18 mgd of effl uent before discharge into the Tualatin River.

AESTHETIC AMENITIES

Gulacy says that more than 1,000 tons of carefully selected and strategi-cally placed boulders create re-aeration waterfalls in channels that direct effl uent through the 2-acre Lower Treatment Wetlands. Two 40- by 8-foot arched bridges made of Douglas fi r complement the placement of many 30-year old contorted pines and more than 500 other trees and shrubs, planted to create a water garden at the direction of Hoichi Kurisu, president and principal designer of Portland’s Kurisu International.

More than 25,000 native plants, chosen for their ability to provide the target 80 percent cover for cooling, have been planted in the Lower Treatment Wet-land. After the plants are established, effl uent from the Forest Grove Facility will be introduced into the new wetland. “It is a unique opportunity for us to plant native species to match the habitat and enhance the way it fi ts into the landscape,” says project manager John Dummer. “We are fi tting treatment into the context of the watershed and making it an amenity for the public.”

To make way for the new wetland, more than 2 acres of asphalt were removed.

Future plans call for reshaping and enhancement of one 50-acre and two 20-acre sewage lagoons to improve habitat and provide additional treatment. The existing lagoons were decommissioned when the plant was built in the 1980s and have become a natural draw to birds and wildlife.

METALS FILTRATION

Another innovative approach to treatment is the planned development of about 2 acres of underground fi lters using peat or compost. As water passes over the media, positively charged metal ions in the water will attach to the media. “The entire project involving the wetlands is a work-in-prog-ress,” says Gulacy.

Until the natural treatment wetlands are complete, the Forest Grove plant operates only about half of the time. During the dry season, it is not permitted to discharge to the Tualatin River. Instead, effl uent is pumped 17 miles to the Clean Water Services Rock Creek Facility for fi nal treatment and discharge.
