Anionic polyacrylamide (APAM) is a water-soluble polymer mainly used in various industrial wastewater treatment processes such as flocculation, sedimentation, clarification, and sludge dewatering. Its molecular chain contains negatively charged groups that can form complexes with cations in solution, thereby exerting precipitation and adsorption effects. APAM has the characteristics of high water solubility, high molecular weight, high ionicity, excellent settling performance, and good stability
