Water Treatment: Effective coagulant for drinking water and wastewater treatment.
Paper Industry: Used for sizing, retention, and pitch control.
Textile Industry: Removes dye and improves water reuse in textile effluent.
Oil & Mining: Aids in solid-liquid separation, tailing water clarification.
Cosmetics & Food Industry: (White PAC) Used where high-purity coagulants are required.
Rapid coagulation and floc formation
Lower sludge generation compared to traditional alum
Effective over a wide pH range
Strong decolorization and turbidity removal capability
Reduces chemical consumption in multi-stage treatment systems
Store in a dry, well-ventilated warehouse away from moisture and direct sunlight. Keep tightly sealed to avoid contact with water or humidity. Avoid stacking with incompatible chemicals.
