User: what is sedimentation?

Weegy: Application of sedimentation processes: In water treatment, sedimentation is commonly used to remove impurities that have been rendered settleable by coagulation and flocculation, as when removing turbidity and color. [ Precipitates formed in processes such as water softening by chemical precipitation are also removed by sedimentation. In municipal wastewater treatment, sedimentation is the main process in primary treatment, where it is responsible for removing 50 to 70% of the suspended solids (containing 25-40 per cent of the BOD) from the wastewater. After biological treatment, sedimentation is used to remove the biological floc produced by microorganisms in these processes, so that effluent quality will approach a standard suitable for discharge into inland waterways. The removal of grit in the preliminary stage of treatment is commonly carried out by means of a differential sedimentation process in which heavy grit is permitted to settle while lighter organic matter is retained in suspension. Further sedimentation after coagulation may be used in tertiary treatment. ]

Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained, and come to rest against a barrier.
