Grit separation is a physical pretreatment that removes all substances of specific weight higher than water (stones, sand/grit, leaves, etc.) running off from covered and uncovered surfaces (roads, car parks, warehouse hardstandings, etc.) and wash areas. The grit separator is a settling tank in which the velocity of the fluid is reduced, allowing suspended solids to settle and accumulate at the bottom of the tank.

USE: Primary treatment of runoff and rainwater from exposed surfaces, hardstandings, car parks, industrial areas, service stations, etc.
