Proper coagulation is one of the most critical processes used in water treatment. The efficiency of the entire treatment process is determined within the first few seconds after the coagulant is added. The article discusses how coagulation works and how it affects filters, then goes on to describe a case study of the Marinette Water Utility. The case study explains the problems the utility experienced with coagulation and how the utility solved its problems by installing a streaming current monitor to control coagulant feed and a sludge pump system to empty sludge basins. A technical drawing of the sludge pumping system, which saves the utility $20,000 per year, is included. A sidebar explains how streaming current monitors work.
