Anionic Polyacrylamide (Anionic PAM) is a water-soluble, high-molecular-weight polymer synthesized by copolymerizing acrylamide with anionic monomers, typically acrylate salts (e.g., sodium acrylate). Its polymer backbone contains negatively charged functional groups (carboxylate groups, -COO\u207b), giving it its characteristic anionic nature.<\/p>\n
Flocculation & Clarification:\u00a0Highly effective for treating inorganic suspended solids, such as those found in industrial wastewater from mining, steel, metallurgy, and coal washing. It excels at aggregating clays, metal hydroxides, and other negatively charged or neutral inorganic particles.<\/p>\n
Drinking Water Treatment:\u00a0Used as a flocculant to remove turbidity and color in raw water purification processes.<\/p>\n
Tailings Dewatering:\u00a0Essential for the solid-liquid separation and dewatering of mineral processing tailings (e.g., iron ore, gold, copper, phosphate, bauxite residue\/red mud).<\/p>\n
Beneficiation Processes:\u00a0Aids in concentrate thickening and filtration.<\/p>\n
Particularly effective for dewatering\u00a0inorganic sludge\u00a0or sludge with a low organic content, often in combination with cationic coagulants.<\/p>\n
Retention & Drainage Aid:\u00a0Improves fines and filler retention, enhances drainage rates on the paper machine wire, and can improve sheet formation.<\/p>\n
Dispersant:\u00a0Used in paper coating processes to ensure uniform pigment distribution.<\/p>\n
Applied in drilling fluid additives, profile modification, and as a friction reducer in some fracturing fluids.<\/p>\n
Soil erosion control (forming a protective crust), sugar juice clarification, and textile sizing.<\/p>","protected":false},"excerpt":{"rendered":"
