Effluent Treatment Plant

The effluent treatment plant is designed to treat the effluent coming from different areas of the plant. The treatment of different effluents varies with the type of effluent.

Oily Water Effluent Treatment

Oily water effluent treatment plant is designed to treat effluent mainly containing oily effluent. The oily water from the Transformer Area, Turbine building, Workshop etc is collected in common collection sump from where water is pumped through the Plate Interceptor. Oil separated from Plate Interceptor is collected in drums & clear water is lead to central monitoring basin through gravity. Sludge generated from the Plate Interceptor is led to the Sludge Pit for further treatment.

Service Water Effluent Treatment

The system is envisaged for treatment of effluent mainly containing turbidity and suspended solids. Service water washing effluent from different areas is collected in common collection pit and then pumped to the flash mixer where chemical mixing takes place. The effluent is dosed with Alum, Lime and Polyelectrolyte to coagulate and flocculate the suspended / colloidal matter. Water then flows through the flocculation tank for flocculation and is finally carried over to tube/lamella settler through gravity where clarification of water takes place. Clarified water is then led to common monitoring basin through gravity. Sludge generated in the process shall be collected and pumped for further treatment.

Coal Handling Plant & Coal Storage Effluent Treatment

Effluent from the Coal handling plant and Coal storage Area is collected and is led through the inlet channel to break the turbulence. The Effluent then flow to the Coal Slurry Settling pond where the discrete particles settle down and the clear water flows to the coal decanted water sump. Decanted water is then pumped to the central monitoring basin.

Sludge Handling System

Sludge collected from different clarifiers is pumped through the Sludge Thickener. Thickened sludge is the further pumped to centrifuge. Sludge cakes generated from centrifuge are disposed off. Supernatant is recycled back to the main clarifier.
