High molecular weight anionic polyacrylamide optimized for efficient suspended solids removal in challenging water matrices.
Excellent bridging and flocculation performance in low-to-medium turbidity applications with high shear resistance.
Consistent solution stability and rapid dissolution without gel formation or undissolved residues.
Low residual monomer content (<0.05% acrylamide), meeting stringent regulatory requirements for industrial water treatment.
Compatible with common inorganic coagulants (e.g., ferric chloride, aluminum sulfate) for synergistic dosing strategies.
Municipal wastewater clarification in secondary and tertiary treatment stages.
Industrial process water recovery in pulp & paper mill effluent treatment.
Sludge dewatering enhancement in belt filter presses and centrifuges.
Mineral processing tailings settling and water reuse in mining operations.
Landfill leachate polishing prior to discharge or infiltration.
