Aims at Treatment & Utilisation of Waste Products in order to avoid Environment Pollution

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

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

Urea, Grommer & Cow dung are added with agitation for Aeration of the Slurry

4. AERATION CHAMBER

5. CLARIFICATION CHAMBER

From “Clarification Chamber”, Liquid effluents gets collected in “TREATED EFFLUENT SUMP”. This water can be used for gardening purposes.
