Water Treatment Process: Plain Sedimentation

Plain sedimentation is a part of water treatment process. It is done to remove suspended particle like clay,silt,sand,etc. Main principle If the specific gravity of suspended particle is greater than the specific gravity of water then those particle with settle down. Higher the difference in specific gravity between particle and water, faster will the particle settle down.
