Sedimentation (water treatment) - Wikipedia

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.

What is Coagulation? - Definition from Petropedia

Coagulation is a process used in water treatment. The water produced by the oil and gas industry is majorly wastewater stream that consists of dissolved and dispersed oil with high salinity levels. Coagulation is important in treating this water. The precipitation of colloids and ions are held in the solution by electrical charges.
