Sedimentation (water treatment)

The physical process of sedimentation (the act of depositing sediment) has applications in water treatment, whereby gravity acts to remove suspended solids from water.^[1] Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation.^[2] Clarifiers are tanks built with mechanical means for continuous removal of solids being deposited by sedimentation;^[3] however, clarification does not remove dissolved solids.^[4]
