Products Description
Polyacrylamide (PAM), CAS 9003-05-8, is a water-soluble linear polymer formed by acrylamide polymerization. It is supplied in two main types: anionic and cationic. The anionic grade appears as white fine powder or granule, with negative charge and adjustable molecular weight. Cationic PAM carries positive charge with controllable charge density. Both dissolve in water but not in most organic solvents. It is non-hazardous goods for transportation. We provide customized specifications for different wastewater systems. It is normally packed in 25kg woven bags, widely exported to sewage treatment plants, mining and paper-making enterprises.

Product Application
Anionic polyacrylamide is mainly used for industrial wastewater sedimentation, coal washing, mineral processing, sand washing and papermaking wastewater clarification. Cationic polyacrylamide is widely applied for sludge dewatering in municipal sewage, food wastewater and printing & dyeing wastewater. It can also serve as retention and drainage aid in paper industry, thickener and lubricant for oilfield flooding, and settling agent for ceramic wastewater. Different ion types and molecular weights are selected according to water characteristics to achieve clear effluent and drier sludge cakes.
