Abstract
A water soluble copper salt, preferably cupric sulfate pentahydrate, is mixed with water. A small quantity of an acidic flocculant is added to the copper sulfate solution to acidify the water and promote dissolving of the copper sulfate in the water. A 25-50% water solution of an acidic flocculant, with or without a cationic polymeric flocculant aid, is prepared and pumped into a processing vessel or tank. The acidified copper sulfate solution is added to the tank and mixed with the acidic flocculant. The algicide-flocculant solution is transported to a municipal water plant and added to raw water in the clarifier to drop out particulates in the incoming water and control algae in the clarifier.
