Solids such as stones, grit, and sand can be faraway from wastewater by gravity when density distinctions are adequate to beat dispersion by turbulence. This is typically obtained employing a grit channel designed to create an ideal circulation fee that permits grit to settle along with other a lot less-dense solids being carried forward to the subsequent treatment stage. Gravity separation of solids is the main treatment of sewage, where the unit system is termed "primary settling tanks" or "Key sedimentation tanks".
