    2020-1-8 · Sedimentation is a physical water treatment process using gravity to remove suspended solids from water. 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.

  • Sedimendation Water Treatment Waste Water Treatment

    Sedimentation is a unit operation to settle out the suspended particles and flocs in water. Sedimentation water treatment is achieved by lowering the velocity of the water below the suspension velocity to settle out suspended particles by gravity. The process is also known as settling or clarification.

    2013-6-5 · When water temperature decreases the rate of settling becomes slower. The result is that as the water cools detention time in the sedimentation tank must increase and the operator must make changes to the coagulant dosage to compensate for the decreased settling rate. In most cases temperature does not have a significant effect on treatment.
