Anionic Polyacrylamide (APAM) is a highly effective water-soluble polymer widely used as a flocculant for wastewater treatment, industrial applications, and sludge dewatering. It has a negative charge that enhances its ability to bind with suspended particles, helping to separate solids from liquids efficiently. APAM is commonly used in municipal sewage treatment, industrial effluent clarification, paper production, and more.

APAM is a versatile, water-soluble polymer engineered for industrial and municipal wastewater treatment, specializing in solid–liquid separation, sludge dewatering, and process water clarification. Available in a range of molecular weights and charge densities, APAM ensures reliable performance across diverse industries.
Application & Dosing Guidance
Stock Solution: Prepare a 0.1–0.5% (w/v) solution using clean water; apply low-shear mixing to prevent polymer chain breakage.
Typical Screening Dose: 1–10 mg/L for clarification; higher dosages may be required for heavy sludge conditioning.
Dosing Point: Add APAM after the primary coagulant (e.g., PAC) to reinforce floc formation and strength.
Jar Test Procedure: Conduct jar tests with rapid mixing → slow flocculation → settling, and evaluate turbidity, floc strength, and sludge volume.
