This is usually obtained utilizing a grit channel meant to produce an the best possible flow rate that permits grit to settle and various fewer-dense solids to be carried ahead to another treatment phase. Gravity separation of solids is the principal treatment of sewage, exactly where the device process is known as "Most important settling tanks" or "Principal sedimentation tanks".
