Thermax provides cost effective Raw Water Clarification, for reduction of suspended solids in surface water. They have been developed after studying the settling and rise rates of suspended impurities under fluctuating conditions.Raw water is first treated to remove the suspended colloidal matter. Small suspended particles in the raw water are coagulated by using poly-electrolyte and coagulant at higher pH. This is then passed through a tube settler where coagulated suspended matter settles down and clearer water flows up. Coagulated suspended matter is taken out from the hopper bottom of tube settler in the form of a thick sludge.
