Flocculant CAS#: Mixture (Main active: Polyacrylamide, CAS 9003-05-8)
Excellent Flocculation Performance: Flocculant can adsorb suspended particles, colloids and organic pollutants in water rapidly, bridge fine particles together to form large and dense flocs. The flocs settle quickly and separate from the aqueous phase at low dosage, greatly improving water clarification efficiency.
Wide Adaptability & Selectivity: Different ionic types including anionic, cationic and nonionic grades are available for diverse raw water and wastewater conditions. It adapts to pH 4–10 and shows good compatibility with PAC, PFS and other inorganic coagulants.
Versatile Uses: It is widely applied in municipal sewage treatment, industrial wastewater clarification, mining tailings dewatering, sludge dewatering, papermaking wastewater, textile wastewater, drinking water pretreatment and oil-water separation.
Powder & Emulsion Form: It is supplied as white fine powder or oil-in-water emulsion. Powder type features high effective content and convenient transportation; emulsion type dissolves fast without lump formation. It has low corrosion and will not introduce excessive impurities when properly dosed.
Flocculant commonly refers to polyacrylamide series products, which are linear water-soluble high-molecular polymers. It relies on charge neutralization and adsorption bridging mechanism to aggregate tiny colloidal impurities. Cationic flocculant is mainly used for sludge dewatering; anionic flocculant is suitable for mineral processing and high turbidity wastewater; nonionic flocculant fits acidic water systems. It is often used together with inorganic coagulants to optimize treatment effect.
