Anionic Polyacrylamide (APAM)
CAS Number: 25085-02-3
Anionic polyacrylamide is a high-molecular-weight water-soluble polymer widely used as a flocculant and coagulant aid in water and wastewater treatment. It carries negative charges along its backbone, making it highly effective for flocculating positively charged suspended solids. This product accelerates sedimentation and improves clarity in industrial effluent, municipal sewage, and mineral processing applications.
