Clarification

Water clarification helps to remove suspended solids (SS) and particulate matter from wastewater - usually with the help of flocculants and coagulants, which improve settling of wastes. Water clarification systems are either rectangular or circular, where water flows from end to end, or where flow occurs from the centre outward, respectively.

Water clarification is used in the treatment of sewage, drinking and industrial effluent water as pre-treatment to further purification processes for commercial and industrial purposes. It is also used as a particular application for grease and oil removal in industrial effluents.
