Polyelectrolyte – cationic

Cationic polyelectrolytes are used in ETPs to remove suspended solids, clarify water, and dewater sludge.

  • Mechanism:

    They carry a positive charge that attracts and binds to negatively charged particles (like colloids and other suspended solids) in the wastewater.

  • Flocculation:

    This neutralization process leads to the formation of larger, heavier clumps called flocs, which settle out more easily.

  • Sludge Dewatering:

    Cationic polyelectrolytes can also improve sludge dewatering by helping to bind the sludge particles together, making them easier to separate from the water.

  • Other Applications:

    Besides ETPs, cationic polyelectrolytes are also used in other industrial wastewater treatment, paper making, and mineral processing
