WasteWater System: Grit Chambers (Horizontal, …

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.

Suspended solids that pass through screens and grit chambers are removed from the sewage in sedimentation tanks. These tanks, also called primary clarifiers, provide about two hours of detention time for gravity settling to take place. As the sewage flows through them slowly, the solids gradually sink to the bottom.
