Eleven polyelectrolytes were tried separately to treat the wastewater from a paint manufacturing industry. Among these, Zetag 66, a cationic polyelectrolyte was found to be most effective. A dosage of 5 mg/L of this polyelectrolyte was found to be adequate to achieve 65% COD removal, 97% suspended solids removal, and 90% heavy metals removal. The use of this polyelectrolyte assumes significant importance as it eliminates the use of alum completely. This elimination of alum consumption results in considerable reduction of effluent treatment plant (ETP) sludge, which is a hazardous waste. The savings that results in the primary treatment is an added advantage.
