It is used in sludge precipitation and sludge dewatering in the treatment of municipal sewage and wastewater from meat, poultry and food processing industries.
As a flocculant, cationic polyacrylamide is mainly used in industrial solid-liquid separation processes, including sedimentation, clarification, concentration and sludge dewatering. The main using industries are: municipal sewage treatment, paper industry, food processing industry, petrochemical industry, metallurgical industry, mineral processing industry, dyeing industry and sugar industry. Wastewater treatment in various industries. It is used in sludge precipitation and sludge dewatering in the treatment of municipal sewage and wastewater from meat, poultry and food processing industries. Through the neutralization of negative charged organic colloids in sludge by positive charged groups and excellent bridging and coagulation function of macromolecule, colloidal particles can be aggregated into large flocs from their suspensions. It is separated from each other. The effect is obvious and the dosage is small.
