What is Polyelectrolyte?
A high molecular weight polymer with ionisable groups used as a flocculant to aggregate suspended particles in water treatment.

Polyelectrolytes are anionic, cationic or non-ionic with molecular weights of 1-30 million g/mol. They work by charge neutralisation and polymer bridging. Dry powder must be dissolved and matured for 30-60 minutes before use.
Common Applications
- Drinking water clarification
- Effluent treatment flocculation
- Sludge dewatering
- DAF flotation
Selection Factors
Correct selection depends on the process objective and site conditions. For Polyelectrolyte, Premix usually reviews these points before recommending equipment:
- Charge type anionic or cationic or non-ionic
- Molecular weight
- Charge density
- Dose by jar test
Why It Matters In Plant Operation
Polyelectrolyte affects process stability, chemical usage, equipment life and final output quality. A correctly selected solution helps reduce trial-and-error at site and supports more predictable daily operation.
