03.1 TREATMENT SCHEME DESCRIPTION:
Water available from Vizag Municipality STP plant is having higher Dissolved
solids and Chlorides. Hence, following scheme is proposed for treatment of
STP water.
Treated Sewage water from the Vizag Municipality shall be stored in the
storage tank. The capacity of the storage tank shall be capable to store at
least 8 hrs of the total intake (2500 M3).
Further the water from the storage tank shall be pumped through Multi-Grade
Filters (MGF) where mostly suspended solids present in the sewage water
shall be removed.
The outlet of the MGF shall be passed through Activated Carbon Filters where
odor and colour of the water shall be removed.
The outlet of the ACF is further distributed in Pellet Plant and Power Plant
based on the requirement of these units after necessary Chlorine dosing.
