Given that the sewage flows by way of them slowly and gradually, the solids gradually sink to the bottom.
The sludge is pumped out from the hopper at the bottom from the tank. About thirty p.c in the sludge is recirculated again into your aeration tank, in which it is actually mixed with the primary effluent.
