Listing ID #3696962

The municipal sewage is mostly treated by conventional activated sludge process. The treated water meets the standards of municipal and state pollution control board and can be used for agriculture or horticulture purpose. The general flow diagram and details are described below.
The raw sewage is pumped to the inlet chamber of treatment plant, from there it flows to screen chamber where physical separation of floating and suspended organic and inorganic materials takes place.
The sewage water from screen chamber flows to grit chamber, where coarse particles of sand, ash and clinkers, egg shells, bone clips and inert materials are removed.
The sewage water from grit chamber flows to primary clarifier where sedimentation of settleable solids takes place. Primary clarifier also reduces the organics load on secondary treatment units.
