Solids such as stones, grit, and sand can be removed from wastewater by gravity when density discrepancies are sufficient to beat dispersion by turbulence. This is typically attained employing a grit channel meant to generate an the best possible movement price that allows grit to settle along with other significantly less-dense solids to become carried ahead to the next treatment method phase. Gravity separation of solids is the main remedy of sewage, in which the unit system is known as "Key settling tanks" or "Main sedimentation tanks".
