3.5.1 SEWAGE TREATMENT PLANT (DESIGN & SPECIFICATIONS)

3.5.1.1 METHOD ADOPTED FOR THE DESIGN (SEQUENCING BATCH REACTOR)

It is proposed to setup a treatment plant for treating the domestic waste, kitchen waste

adopting Sequencing Batch reactor using diffused aeration, the STP has been designed to cater

to the needs of Industrial Park considering future expansion to an area of 128.245 Hectare (1.2

MLD). The other modes of treatment considered before arriving at SBR process are FAB

(Fluidized Aerobic Bio Reactor), ASP (Activated Sludge Process) etc. The advantages and

disadvantages of the each scheme, initial investment and maintenance cost etc. were compared

and finally arrived at providing a STP using SBR – Sequencing Batch Reactor.

S No. Name of the

Unit Purpose

1. Coarse and fine screen chamber

For removing unwanted floating materials.

2. Grit chamber To remove the grits

3. Sequencing Batch Reactor

Activated Sludge Process for developing the bacterial culture, which stabilizes the waste using submerged aerators. The SBR will also act as Secondary clarifier during the settle process and as a pre-filtration tank during the decant phase.

3a) selector zone Biological Selector Zone prevents sludge foaming and sludge bulking

3b) DO Meter DO Meter helps in measuring DO concentration available in the basin and also Oxygen Uptake Rate (OUR) based control of the process. This ensures 30 – 40% power saving

3c) Diffusers

Fine bubble polyurethane membrane diffusers are provided for efficient transfer of oxygen from air to meet the process demand.

Air grid with adjustable supports are provided for installing all diffusers at same level and hence ensuring uniform air distribution across plan area

3d)

Sludge Recycle (RAS) and Sludge Wasting (SAS)

RAS pump recirculates part of biomass into selector compartment during fill/aerate mode. SAS pump pumps out excess sludge from SBR basins during decanting period for further disposal.

3e) Automation For complete automatic Cycle control and operation with facility to hook the complete operation to a central Control Desk.

4. Decant Tank To collect and store the supernatant from the SBR reactor and store it prior to filtration.

5. Ultraviolet Disinfection

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


6. Filter Press / Centrifuge

To de-water the sludge taken out of settling tank and to convert the same into manure.

7. Treated Water Tank

To collect the final treated water from the outlet of Activated carbon filter for reuse.

8. Sludge Holding Tank

Sludge holding tank are proposed for sludge dewatering.

Figure 3.3 Treatment flow chart


Figure 3.4 Sewage Treatment Plant Layout


3.5.1.2 Sequencing Batch Reactor (SBR)

Sequencing batch reactor is a modification of activated sludge process which has been

successfully used to treat municipal and industrial wastewater. The difference between

Sequencing Batch Reactor and Activated Sludge Process is that SBR performs equalization,

biological treatment and secondary clarification in a single tank using a timed control

sequence.

SBR is a fill and draw type reactor system involving a single complete mix reactor in which all

steps of the ASP occur. An SBR goes through a number of cycles per day; a typical cycle may

consist of 3-h fill, 2-h aeration, 0.5-h settle and 0.5-h for withdrawal of supernatant. The

detention time for SBRs generally ranges from 18-30h, based on influent flow rate and tank

volume used.

Sequential batch reactor process is selected by considering the following factors,

• Reliability.

• Vector Nuisance.

• Area availability.

• Power requirement.

• Capital cost.

• Operation & Maintenance cost.

Technologies considered for selection

• Activated sludge process.

• Fluidized Aerobic Bio reactor.

• Membrane Bio reactor.

Advantages of SBR Technology

• Variable Design – Treats fluctuating loads.

• Excellent Performance including N, P Removal.

• Minimum Power requirement.

• Minimum Land Requirements.

• Fully Automatic computer controlled.

• Stainless Steel Components.

• Easy future augmentation.

3.6.1 BARC TECHNOLOGY

Bhabha Atomic Research Centre (BARC), Mumbai Bhabha Atomic Research Centre

(BARC) provides a broad spectrum of scientific and technological activities extending from

basic laboratory bench scale research to scale up plant level operations. Its functional domain

covers all walks of science and technology – stretching from classical school of thoughts to the

emerging novel fields of interest. The core mandate of this institution is to provide Research

and Development support required to sustain one of the major peaceful applications of

nuclear energy viz. power generation.

Functionality

The system is based on a floating dome design, a proven technology for manure digestion in

India and China. It is a two stage continuous wet system. The waste gets hydrolyzed in a first

stage and in a second stage methane is produced. The reactor is constructed underground,

reducing the building costs and the reactor contents flow under gravity by volume

displacement. Every time the digester is fed the equal amount for reactor content will leave

the digester. The biogas plant runs on kitchen waste that is pretreated (mixed with hot water

that is heated up by solar heating and pulped) and discontinuously fed (Batch-System) to the

thermophilic aerobic pre-digester.

The effluent from the pre-digester is fed to the methane reactor where biogas is produced.

The effluent from the methane reactor is collected in open pits that are provided with sand

filters. When the pit is filled up, the manure is taken out and spread under shade for drying.

The excess water filters out in an underground tank and is reused in the system.

Schematic description of the Nisargruna biogas plant is shown below. The plant operates in

two-phases with a thermophilic and a mesophilic digester


Figure 3.6 Process flow of BARC Technology

Benefits of BARC Technology

Efficient waste management technology.

Biogas to be used as energy source in tractors, buses and gen sets.

It is renewable energy resource.

Carbon neutral fuel and helps in climate mitigation program.

Project has all the elements of sustainability.

Solid waste after decomposition to be used as manure by farmers in nearby regions.

4.6 DEVELOPMENT OF GREENBELT

To provide a dense tree cover and to provide good sound and dust barriers, the

planting of tree species in open areas will be done. The recommended plant species are

listed in Table 4.5. As per guidelines of TNPCB, the three main criteria for selection of

plants may be as follows,

Trees, shrubs will have dense foliage with a large surface area, because leaves absorb

pollutants.

The species chosen must be resistant to pollutants, particularly in the early stages of

their growth.

The species chosen may be native species and drought tolerant.
