High molecular weight anionic polyacrylamide optimized for superior flocculation in neutral to alkaline aqueous systems.
Excellent shear stability and rapid dissolution characteristics, minimizing gel formation during preparation.
Low residual monomer content (< 200 ppm), meeting stringent regulatory requirements for industrial water treatment applications.
Consistent performance across variable water chemistries, including high turbidity and varying ionic strength conditions.
Compatible with common inorganic coagulants (e.g., ferric chloride, aluminum sulfate) for synergistic solid-liquid separation.
Municipal wastewater treatment — primary and secondary clarifier sludge dewatering.
Industrial effluent treatment — mining tailings clarification and coal washery water recovery.
Pulp and paper process water clarification and fiber retention enhancement.
Mineral processing — flotation tailings thickening and concentrate dewatering.
Landfill leachate treatment — suspended solids removal and biological sludge conditioning.
