Conceptual Plan Mahindra Industrial Park Chennai Limited
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

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.
