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

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

* 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

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.

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.

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 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.

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:

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.
3.6 LANDSCAPE DEVELOPMENT:

wind protection, and a low-maintenance landscape that is adapted to the local environment.
Landscape development is proposed in the project, following trees / vegetation is proposed to be
