Primary Clarification : STRAINER
Macro particles Such as
Polyethylene,Conc. Fat/Sludge,And other WasteProducts areSeparated.

2. AGITATION CHAMBER: Sewerage is agitated through Pump Unit to break
down all Macro molecules of Sludge

In the Third section, after being passed out from the “Agitation Chamber”, The sewerage enters into
“DECOMPOSITION CHAMBER”.
Here, In the Decomposition Chamber, the waste products were allowed for Anaerobic
Decomposition, resulting in the Production of Methane Gas.
Methane gas is used for Electricity Generation, for
partial compensation of the Power Consumption by the plant
