2.3 BRIEF PROCESS DESCRIPTION

2.3.1 Pumping

The inlet sewage coming to pumped manholes is pumped to bar screen

chamber using cutter pumps separately for Soil, grey water and kitchen

waste water.

2.3.2 Screening

The Sewage is led into a Bar Screen Chamber provided with MS Bar

Screen. Bar screen shall be provided at inlet point in the bar screen

chamber. Screen with openings generally of uniform size to remove

suspended or floating matters in sewage to be provided. The primary

screen has to have size of 10 - 15 mm and secondary screen has to have

size of 4-5 mm. The velocity shall be maintained so as to avoid settling

of grit or organic matter. Bar screen shall be so designed that it can be

cleaned manually from outside of tank.

2.3.3 Oil & Grease Chamber

The raw sewage after passing through Bar Screen shall be taken into an

oil & grease trap for removal of oil and grease from the effluent.

2.3.4 Raw Sewage Sump (Collecting Tank)/ Equalization tank

This sump is provided to dampen the flow fluctuations and, in order to

keep the solids in suspension, pre-aeration is provided with coarse

bubble tubular diffusers.

The sewage collection tank has to have a storage size of 50% of daily

sewage generation/sewage treatment. The raw sewage from oil & grease

trap is collected in a raw sewage collecting sump. The raw sewage is

pumped using submersible non-clog SS pumps of suitable capacity.

Facility has to be made to purge air in the collection tank to keep its

content homogenous and avoid high anaerobic condition in the tank

2.3.5 Aeration tank with submerged membrane bioreactor

The Sewage will be pumped to aeration tank which comprises fine pore

diffusers and PVDF hollow fiber submerged membrane. The efficiency of

BOD removal is considered as between 90 – 97% in this bioreactor.

The MBR tank contains highly concentrated biomass, so called activated

sludge, which transforms the organic matter of the wastewater into

carbon dioxide, water and biomass. The activated sludge is kept in

aerobic conditions at all times by continuous aeration.

Sludge will be retained in the Aeration tank and excess sludge will be

pumped/ passed to sludge holding tank and then pumped to Filter press

whenever MLSS measured is higher than designed.

2.3.6 PARAMETERS OF DESIGN OF MBR TANK

Process type – Aeration

Flow regime – Completely mixed

MLSS – 6000 - 10000 mg/lit

MLVSS/MLSS – 0.8

F/M Ratio – 0.1 – 0.12

drain valve and sent to sludge dewatering press. Leachate from the

press can be sent back to collection tank or final treated water tank.

Sludge cake should be stored in proper place as per the norms and

guidelines.

2.3.11 Solids Handling (Filter Press)

The Sludge from the sludge drying bed shall be pumped for solid- liquid

separation on to Filter Press. The filtrate from the Filter press will be

collected and can be used for horticulture or dispose in solid form.
