Overview
Plant Capacity :
1000 M3 / Day
Process
Involved : Activated Sludge Process Type : Extended Aeration System
Steps
Involved in Treatment Process,
-
Bar
Screen: To remove floating objects which are harmful to the pumps &
other machineries
-
Grit chamber cum oil & grease trap:
To remove grit floating
matter oil & grease which gets coated its carrying capacity &also it
prevents transfer of oxygen in the STP. Detention time is 15
minutes.
-
Pump House :
2 nos. of Raw effluent pumps (each of capacity 44
M3 /hr @ 10m head) 2 nos. return storage pumps (each of capacity 44
M3 /hr @ 10m head)
-
Aeration tanks:
Biological process takes place in aeration tank
which are used to convert the finely divided and dissolved organic
matter in wastewater into flocculant settleable solids.
The
biological process selected to remove organic matter is called
Activated Sludge Process. The aeration tank is equipped with
aerators to transfer atmospheric oxygen to sewage. The sewage is
aerated in the aeration tanks with the help of surface aerators
round the clock to build up necessary biological system.
-
Secondary Clarifier: To achieve remove of biological solid and its return to
aeration tank the settled sludge will be collected in a hopper of
the clarifier and pumped back to aeration tank with the help of
return sludge pumps. When the concentration of solids in the
aeration tank exceeds 4000 mg/lit, part of this sludge is sent to
sludge drying beds for dewatering.
-
Treated
sewage chlorination: The clear overflow form the clarifier is
collected in a sump and either used for gardening or disposed off in
the strom drain after proper chlorination which disinfects treated
sewage
-
Sludge
Drying Beds : For dewatering the excess sludge, sludge-drying beds
are provided. While water passes through' it, which is collected
through drains and taken back to aeration tank.
-
Effluent Disposable Pumps: Treated sewage after chlorination shall
be pumped for gardening in Hospital Complex .covering 6 acres and in
J. N. Medical College covering 15 acres.
