Grit separators

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 stilling tank in which the velocity of the fluid is reduced, allowing sedimentation of the suspended solids which settle and accumulate at the bottom of the tank

Use and specifications
1. STILLING AREA: zone through which the separated and treated effluent flows

2. SEDIMENTS: area in which temporary accumulation of the solids (food waste, etc…) takes place
