Answer 2

Sedimentation

• 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.

You can use loading process to faster the process.

• The process of adding alum to water to hasten sedimentation is called 'loading'. Why has this name been given to the process? When alum is added to water, it dissolves in water and makes the suspended impurities heavier making them settle down quickly. Therefore, the addition of alum is known as loading.
