DESIGN DETAILS FOR THE PROPOSED SEWAGE TREATMENT PLANT AND DESIGN ASSUMPTIONS (100 KLD STP FOR RESIDENTIAL DEVELOPMENT) BASED ON SEQUENTIAL BATCH REACTOR TECHNOLOGY:

TREATMENT METHODOLOGY ADOPTED:

The Sequencing batch reactor (SBR) process is a sequential suspended growth (activated sludge)

process in which all major steps occur in the same tank in sequential order (Figure 1). There are two

major classifications of SBRs: the intermittent flow (IF) or “true batch reactor”, which employees all

the steps in figure 1, and the continuous flow (CF) system, which does not follow these steps.

Both have been used successfully worldwide installations. SBRs can be designed and operated to

enhance removal of nitrogen, phosphorus, and ammonia, in addition to removing TSS and BOD. The

Sl. No.

Parameter Quality Of Raw Sewage

Quality Of Treated Sewage as per KSPCB Circular.

1 pH 6 – 8 6 – 9

2 BOD5, mg/L 250 ≤10

3 Turbidity, NTU 100 ≤ 2

4 E.coli --- Nil

5 Residual Cl2, mg/l --- ≥ 1



40

intermittent flow SBR accepts influent only at specified intervals and, in general, follows the five-step

sequence. There are usually two IF units in parallel. Because this system is closed to influent flow

during the treatment cycle, two units may be operated in parallel, with one unit open for intake while

the other runs through the remainder of the cycles. In the continuous inflow SBR, influent flows

continuously during all phases of the treatment cycle. To reduce short circuiting, a partition is

normally added to the tank to separate the turbulent aeration zone from the quiescent area.

Total quantity of raw effluent = 100 m3/day = 6.25 m3/hr

(Assuming 16 working hrs/day)

BOD3 @ 270 C = 250 mg / L

Expected BOD reduction:

1. Influent BOD = 250 mg/L

2. BOD reduction in SBR = 95 %

Therefore BOD at the outlet of secondary

treatment = 12.5 mg/L

3. BOD reduction with tertiary treatment like

coagulation, filtration and disinfection = < 10 mg/L



41

1. BAR SCREEN:

* Size of the unit : 0.4 m x 0.6 m x 1.2 m long

* Function: To separate coarse matter from the raw effluent.

2. EQUILIZATION CUM NEUTRALIZATION TANK:

* Average BOD of effluent at the inlet of the pre-aeration tank = 250 mg/L

* Total organic load with 20% BOD reduction considered = 50 mg/L

* Total organic load to be removed = 5 kg/day

* Total oxygen required assuming 2 kg of O2/kg of BOD removed = 10 kg/day

* Let us assume

Alpha = 0.6

Beta = 0.7

Oxygen transfer at 0.25 m depth = 25%

Density of air = 1.2 kg/m3

Percentage of oxygen in atmosphere = 21% * Therefore air required for aeration = 10.0

---------------------------------- 0.6 X 0.7 X 0.25 X 1.2 X 0.21

= 377.93 m3/day * Air requirement per hour = 23.63 m3/hr

(duration of air supply = 16hrs)

* Type of aeration: coarse bubble diffused aeration system

* Detention time = 4 Hrs

* Volume of the unit = 25 m3

* Depth of the unit = 2 m

* Area of the unit = 12.5 m2

* Size of the unit = 3.6 m x 3.6 m x 2 m

42

ASSUMPTIONS FOR SBR PROCESS KINETICS

* F/M ratio = 0.15

* MLSS = 4000 mg/L

* Net sludge yield = 0.76 kg MLSS/kg BOD5

* Min. solids retention time = 8 days

* Reactor volume decanted each day = 60%

* Dissolved O2 liquor concentration = 2 mg/L

* Oxygen co-efficients

kg of O2/kg of BOD5 = 1.28

kg of O2/kg of NH3N = 4.6

* Oxygen transfer factors

ά (typical for coarse bubble diffusers) = 0.85

ß (typical for domestic wastewater) = 0.95

* Typical O2 transfer rate for coarse bubble diffusers = 1.25 kg O2/KWH

* No. of cycles/day = 4

ii) SBR design calculations

a) Reactor volume

* BOD5 removed (kg/day) = [(BOD influent - BOD effluent) (mg/L)] x flow (L/day)]

BOD5 = (240 - 20) X 50 X 1,600 = 18 kg/day 106

* Required aerobic mass = BOD removed F/M Ratio

= 18/0.15 = 120 kg MLSS

* Reactor volume (low water volume) = MLSS mass (kg) / MLSS concentration

= (120/4,000) x 1000

Therefore reactor volume = 30 m3

* Since the decant volume represents 60% of the total volume

TSS, mg/L 200 30

(NH3 – Ammonia), mg/L 25 1

Total Phosphorous, mg/L 10 2

TKN, mg/L 40 5



43

Total reactor volume = [10.5/{(100% - 60%)}/100] = 75 m3

b) Decant volume

* Total decant volume = total reactor volume - reactor volume

(Low water level)

Total decant volume = 75 – 30 = 45 m3

c) Detention time

* Maximum detention time = (total reactor volume/flow) x 16 hr/day

* No. of working hrs/day = 16 hrs

* Max. detention time = (26.25/35) x 16 = 12 hrs

* Max. retention time = (15.75/35) x 16 = 7.2 hrs

d) SBR dimensions

* Basin area = basin volume/basin depth

* Depth of the basin = 2.75 m

* Therefore basin area = 75/2.75 = 27.27 m2

* Providing 2 SBR tanks

* Basin area = 27.27 m2

* Basin width = 5.23 m

* Basin length = 5.23 m

* Size of the unit = 5.23 m x 5.23 m x 2.75 m

Aeration:

* Nitrogenous O2 demand (kg of O2/day) = NH3 - N oxidized (kg/day) x kg O2/kg of NH3N

* Carbonaceous O2 demand (kg of O2/day) = BOD5 mass (kg/day) x kg O2/BOD5

* NH3 - N oxidized (kg/day) = TKN removed (kg/day) - synthesis N (kg/day) * TKN removed = (40 – 5) 100 / 1000

= 3.5 kg/day

* Synthesis N = 5% waste activated sludge of total daily sludge production

* Sludge production (kg/day) = net sludge yield (kg MLSS/kg BOD5) x BOD5 removed (kg/day)

Therefore sludge production = 13.68 (kg of MLSS/kg of BOD5)

= 1.68 kg/day

* Synthesis N = 5/100 x 13.68 = 0.684 kg/day

* NH3 - N oxidized = 3.5 – 0.684 = 2.816 kg/day



44

* Nitrogenous O2 demand = 2.816 x 4.5 = 12.9536 kg of O2/day

* Carbonaceous O2 demand = 0.684 x 1.28 = 0.87552 kg/day

* AOR (kg/day) = nitrogenous O2 demand + carbonaceous O2 demand (kg/day)

where AOR = Actual Oxygen Requirements (kg O2/day)

* AOR = 12.9536 + 0.87552

= 13.82912 kg/day SAOR(kg O2/hr) = [AOR x Cs x teta (T-20)] / [ae x (beta x Csw - C0) x blower usage(hr/day) where SAOR = standard actual O2 requirement (kg O2/day)

teta = temperature correction factor = 1.024

Cs = O2 saturation concentration at standard temperature and pressure

= 9.02 mg/L

Csw = concentration correction for elevation 1000 ft.

= 9.02 - 0.0003 x elevation

= 8.72 mg/L

(NOTE: 0.0003 may be used as a rule of thumb describing a 0.0003 mg/L rise/drop in DO saturation concentration per every foot of elevation increase /decrease.) C0 = 2 mg/L

ae = 0.85

beta = 0.95

T = 30 0C (67 0F)

Blower usage= 16 hrs/day

(based on 4 cycles per day (6 hr/cycle), 1.0 hr fill time, 3.5 hr react time ,0.75 hr settle time, 0.5 hr

decant time, and 0.25 hr idle time)

SAOR = 13.829125.531648 x 9.02 x 1.024 (30 – 20)

0.85 x (0.95 x 8.72 – 2 ) x 16

SAOR = 1.850229 kg of O2/hr

Sludge and decant flows * Sludge flow rate (L/day) = sludge mass flow (kg/day) / sludge density (kg/L)

* Typical sludge density = 1.02 kg/L

* Therefore sludge flow rate = 13.68/1.02 = 13.42 L/day



45

* Size of the aerobic digester required = 1.95 m dia X 2 m depth

* Size of the filter press required = 3 m2

* Let the size of each plate = 0.47 m × 0.47 m

DESIGN DETAILS FOR THE PROPOSED SEWAGE TREATMENT PLANT AND DESIGN ASSUMPTIONS (50 KLD STP FOR COMMERCIAL DEVELOPMENT) BASED ON ACTIVATED SLUDGE PROCESS TECHNOLOGY:



50

TREATMENT METHODOLOGY ADOPTED:

The design is made keeping in mind the total quantity of generation of 50,000 Lts. The modular

technology is adopted in the design, i.e., when the flow increases drastically, the present units itself

can be used with the additional units attaching to it in modules, which would be economical and

saves on the area required too.

The units proposed for the proposed STP with activated sludge process are:

SL. No. Name of the Unit Purpose

1 Bar Screen Chamber For removing all floating matters

2 Equalization Tank To even out the flow variations, and providing uniform mixture of sewage by providing Coarse bubble aeration

3 Aeration Tank Activated Sludge Process For oxidization of Biological waste

4 Settling Tank To separate out the solids from the treated sewage, And to separate clear supernatant liquid.

5 Alum Doser Accelerate rate of settlement

6 Mechanical Filter Press To de-water the sludge taken out of secondary clarifier and to convert the same into manure.

7 Pressure Sand Filter To filter out suspended solids if any in the treated water.

8 Activated Carbon Filter To remove color and Odor if any in the filtered water.

9 UV Sterilizer To disinfect the treated water to make it safe to come in contact with humans so that the treated water can be used for flushing/gardening / allied uses.

The Sewage Treatment Plant design calculations as given below for plant of Capacity 50KLD

Design of the individual units:



51

1. Bar Screen Chamber:

Provide a chamber of size 1.0 m x 0.60 m to suit sewer gradient to accommodate an inclined

bar screen with opening less than 10 mm. Provide a bar screen of 20 X 6 mm flats with 10mm

spacing in between.

Design Criteria:

Velocity through screen : 0.8 m/Sec.

Discharge : Discharge / day x 8 / 24

= 50 x 8/24 x (1/ (24x60x60))

= 2.0X10-4Cum. /sec

Peak Load = 2.0X10-4 X3.0

= 6.0X10-4 m3 /sec

Adopting screens with bars of 6 mm width and 10 mm clear opening considering 1.2 times the net

area of opening,

Net Area = 7.2X10-4 /0.80

= 9.0X10-4 m2

Gross area = 1.2 times of the net area of opening

= 1.2 X 9.0 X 10-4

= 10.8X 10-4 m2

Gross area of screen needed would be 1.0X0.6mt for ease of maintenance.

2 Equalization tank:

The flow from the bar screen chamber is let into the equalization tank of minimum 8 hours capacity. This tank is provided to even out the flow variation, and to provide a continuous feed into the secondary biological treatment units.

Design flow = 50, 000 Lt/day

Provide min 8 hours holding capacity.

Hence required volume of the tank = 16.67 m3

Provide a tank of 20,000 Lt Capacity.

The tank size would be 6.0X1.5X2.3 m



52

3 Aeration tank with extended aeration (Activated Sludge Process)

Flow = 50 KLD.

Assumption:

Retention period = 16hrs

Vol. of the aeration tank = 50X16 = 33.33 m3 24

Hence provide aeration tank of capacity 35,000 liters capacity.

The aeration tank size required will be of dimension

3.2 X 3.7X3.0m (effective volume) since the oxygen transfer

rate using diffused aeration system will be more with increase in depth of the tank.

"BOD5 after treatment <10 mg/lit

"BOD5 Loading = 250 mg/lit

"Total BOD5 load = 50x1000x250 kg/day

1000000

"Total BOD5 load = 12.50 kg/day

BOD5 load in Kg/day in the aeration tank = 12.5 Kg

Oxygen required in Kg/day = 25.0kg/day

(2 kgs of Oxygen is required for every Kg of BOD5 to be removed)

% Of Oxygen in air = 0.21 Density of air = 1.2

Oxygen Requirement = 100 m3 / kg 02 / day

Therefore air requirement in Cum. / Day

= 25 x 100 =2500 cum / Day.

Consider 20% excess assuming air requirement in the equalization tank.

Total air required = 3000cum /day = 59.0 cfm

Hence provide 2 blowers each of each of 30Cfm.

With an operating pressure of 0.5 KSC.

Transfer rate of oxygen in 1 mt. Long membrane diffusers = 10 cfm /hr.

Therefore Total no. of membranes required = 60/ 10

= 6 Nos.

minimum 16 hours holding capacity. This tank is provided to hold the treated effluent and give an

even flow to the pressure sand filter.

Design flow = 50,000Lt/day

Provide min 16 hours holding capacity.

Hence required 35 m3 Capacity.

The above tank is divided into 2 compartments of 20 m3 for final effluent and 15 m3 clarified water

respectively.

The dimension of Clarified water tank will be 2.3X2.9X 2.40 m liquid depth

The dimension of final water tank will be 2.3X2.9X3.0 m liquid depth

OCCUPANCY PHASE: The wastes that are generated from the day to day activities which are in solid form are categorized

as solid wastes. Solid Wastes include dry refuse of house and street sweepings, crockery, Kitchen

Wastes etc., collection, disposal and management of Solid Wastes are very important to avoid the

nuisance and unhygienic conditions. The quantity of solid waste generated from the project is

calculated as below.

SOLID WASTE GENERATION:

Quantity of solid waste generated for EC obtained configuration: 164 Kg/day

Quantity of solid waste generated for project after expansion and modification:

Residential apartment

Commercial Block: a) Hotel b) Commercial Activity

660 Persons 305 Persons 342 Persons

Assuming solid waste generation rate as 0.4 kg/person/day for Residential Activity, 1.2 Kg/person/day for Hotel and 0.2 Kg/person/day for commercial activity.

Quantity of solid waste generated from

Residential apartment

Commercial Block: a) Hotel b) Commercial Activity

264 Kg/day ----- A 366 Kg/day ----- B 69 Kg/day ----- C

Therefore total quantity of solid waste generated: (A + B + C) 699 Kgs/day

Organic solid waste: 60 % of the total waste 420 kgs/day

Inorganic solid waste: 40 % of the total waste 279 kgs/day



62

The solid wastes generated are segregated at point of generation, collected and stored at a common

designated place and Organic solid waste will be treated in an organic converter, the product will

used as manure for Landscape. The inorganic waste is sent for recycling. The details of Operational

procedure and Flow chart of Organic Converter is as below



63

The compost formed by this method will have a pH value of 6.5 – 7.5 C:N ratio of 15:1 and organic

matter of 40 – 50%. There will not be any pathogens and the pellets manufactured will have a

calorific value of 3500 to 4000 Kcal/Kg.

ENVIRONMENTAL MANAGEMENT PLAN

1. INTRODUCTION:

The Environmental Management Plan (EMP) is aimed at mitigating the possible adverse impact of a

project and ensuring the existing environmental quality. The EMP covers all aspects of planning,

construction and operation of the project relevant to environment. It is essential to implement the

EMP right from the planning stage continuing throughout the construction and operation stage.

Therefore the main purpose of Environmental Management Plan (EMP) is to identify the project

specific activities that would have to be considered for the significant adverse impacts and the

mitigation measures required.

The construction phase impacts are short term, restricted to the plot area and not envisaged on the

larger scale. In the operational phase the environmental impacts are due to continuous operation of

the project, hence, the emphasis in the Environment Management Plan (EMP) is to minimize such

impacts. The following mitigation measures are recommended in order to synchronize the economic

development of the project area with the environmental protection of the region.

The emphasis on the EMP development is on the following;

Mitigation measures for each of the activities causing the environmental Impact.

Monitoring plans for checking activities and environmental parameters and monitoring

responsibilities.

Role responsibilities and resource allocation for monitoring; and

Implementation of the Scheduled plan.

Environmental management plan has been discussed in the following sections separately for

Construction phase and Operational phase:

3.4 SOLID WASTE MANAGEMENT:

The solid wastes generated during operation phase are categorized under

Three types: Domestic/Residential Waste

Wet Garbage: Food waste, Lawn mowing wastes etc.,



72

Dry Garbage: Paper, Plastic, Bottles, etc.,

Sludge from Sewage Treatment Plant (STP)

The solid waste generated and its management is detailed in Annexure – F.

The various mitigation measures to be adopted during collection and disposal of wastes are as

follows:

It is preferable that the container and bins used for collection of waste are of closed type so

that the waste is not exposed and thus the possibility of spreading of disease through flies

and mosquitoes is minimized.

Collection system is properly supervised so that quick and regular removal of waste from the

dustbin is practiced.

Door to door collection will be done to collect the solid wastes. The wastes will be treated in

organic converter and the inorganic wastes such as plastic materials, glass & metal wastes

are handed over to the waste recyclers.

3.5 STORM WATER MANAGEMENT:

As the project location is blessed with fairly good rainfall, it is planned to collect the storm water at

different gradients of the location. There will be rainfall runoff from building roof-tops, roads and

pavements and greenbelt area. Necessary provision will be made to collect the quantity of rainfall

runoff during the most rainy day of season. Necessary rain harvesting pit/recharge pit at every 15 m

centre to centre have been envisaged. A storm water drain with 600mm wide with RCC precast

perforated cover and 1,800 mm dia RCC precast Ring soak pit will be provided around the periphery

of property and designed as per building by-law (schedule 12). The details of the rain water

harvesting facilities can be interpreted in the layout plan.

1) Health camp for laborer’s family:

Periodical health camps are organized to monitor and facilitate the occupants of the labor camps.



74

HEALTH RISK AND DISASTER MANAGEMENT:

Public health and safety:

Since all the construction related activities are confined to the project site, minimal health related

impacts are envisaged within the project influenced area during the construction stage.

At the project site on an average of 75 persons are engaged, who face direct exposure to dust and

noise generated from the construction activity. This is likely to cause health related affects such as

asthma, bronchitis etc. and hearing impairments.

To minimize these anticipated impacts, following approaches are made

Use of water sprinklers to prevent dust from being air borne.

Providing suitable personal protective equipments (PPE) like mouth mask with filters, noise

mask, helmets etc.

Periodic health check up camp for the laborers are arranged.

Provision of safety belts.

In case of injury Ion site medical treatment and transport are organized.

Safety engineer is employed.

Regular visit of resident medical officer to take care of the first aid and primary medication in

case of emergency.

RAIN WATER MANAGEMENT SCHEME

RAIN WATER HARVESTING AND GROUNDWATER RECHARGING:

VOLUME OF RAIN WATER HARVESTED:

The total amount/quantity of water i.e., received in the form of rainfall over an area is called the rain

water endowment of that area, out of which the amount of water that can be effectively harvested is

called the rain water harvesting potential.

Rain Water harvesting potential = Intensity of Rainfall (m) x Roof Area x

Impermeability Factor

The collection efficiency accounts for the fact that all the rain water falling over an area cannot be

effectively harvested due to losses on account of evaporation, spillage or run off etc.,

According to the data available from the Indian Meteorological Department, the Average annual

rainfall around month of September = 194.80mm

Assuming that about 90% Rainfall can be effectively harvested.

Number of Rainy Days = 9.3

Therefore the I.R = 194.80/9.3= 20.94 mm/day or 0.02094 m/day

or 0.021 m/day

Quantity of roof top rain water harvested from the project:

The top floor area of the project (Apartment and Commercial block) is about 3,046 sq m.

For rain water harvesting consider 75 % of this total area = 2,284.5 sq m.

Total Quantity of Rain Water that can be harvested from the building is as follows.

Rain water (Q) from Roof top = 0.021 x 2284.5 x 0.9

= 43.17 cum/day or say 44 cum/day

Rain water storage sump of 60 cum capacity is proposed to collect the rain water and will be reused

for domestic purposes.

RAIN WATER FROM PAVED & UNPAVED AREAS:

The amount of storm water that the landscaped area will produce can be determined by considering

the impermeability factor to be 0.3.



78

Q = 0.021 x 2,157.60sq m x 0.3


The amount of storm water that the paved area will produce can be determined by considering the

impermeability factor to be 0.9.

Q = 0.021 x 2,246.19 sq m x 0.9


The Total amount of storm water = landscaped area + paved area

= 16 + 43 cum/day

= 59 cum/day

Ground water recharging pits along the inner periphery of the boundary wall with recharging pit of

size 1.2 m dia x 7.0 m deep spaced with 10 nos recharge pits. Recharge pits are filled with graded

media comprising of Boulder at the bottom and with coarse aggregates to facilitate percolation of

harvested rain water to Recharge Ground Water table. The Pits are interconnected in such a way

that the rain led to the first recharge pit is also led to the next pit. The excess rain water shall be

drained off to the storm water drain.
