Features Of Kemira Superfloc SF4818 Cationic High Molecular Weight Flocculant Surfactant

  1. High cationic charge density for rapid neutralization of negatively charged colloids and suspended solids.

  2. Exceptional molecular weight enabling superior bridging flocculation and formation of dense, shear-resistant flocs.

  3. Optimized for low-dose performance—delivers effective solid–liquid separation with reduced chemical consumption.

  4. Excellent solubility and dissolution kinetics in cold water, minimizing preparation time and operational downtime.

  5. Stable performance across a broad pH range (pH 4–9), supporting flexibility in diverse process conditions.

Typical Applications Of Kemira Superfloc SF4818 Cationic High Molecular Weight Flocculant Surfactant

  1. Municipal wastewater treatment: primary and secondary clarifier sludge dewatering.

  2. Industrial effluent treatment: pulp and paper mill white water clarification and fiber recovery.

  3. Mineral processing: tailings dewatering and thickener feed conditioning in iron ore and coal operations.

  4. Sludge conditioning prior to centrifuge or belt press dewatering in biogas and anaerobic digestion facilities.

  5. Drinking water treatment: coagulant aid for turbidity removal and enhanced sedimentation efficiency.
