Grit Chamber in Wastewater Treatment

The grit particles in the compartment gather down at its base, the grit chamber has different divides, such as the incoming sector, the outgoing sector. The incoming sector spreads the water flow to the grit compartment; the outgoing sector gathers the sewage water after the elimination of the gravels.

A grit chamber is usually installed before primary sedimentation tanks and it is sensible to say that it should be placed well before wastewater pumps. There are basically three different types of grit chambers. One is called the horizontal flow type, another is the aerated grit chamber and the last one is the vortex type. The design of a horizontal flow type is such that as wastewater flows
