Polyelectrolytes are charged polymers are bi-functional in nature that can be used as flocculants and de-flocculants , thickeners, clarifiers, dispersant agents relying on their atomic weights. Solid-liquid separation targets the flocculating nature of the polyelectrolyte whereas deflocculant fill in as as a scattering or dispersing agent.It can be categorized into cationic polyelectrolyte and anionic polyelectrolyte.
Polyelectrolytes enhance the performance of the process thereby meeting the needs in many industrial applications. These applications may include water purification, oil recovery, metallurgy & metal smelting, BOD /COD reduction, paper & board production, mineral processing, , super-plasticizers, implant coating, ,discoloration ,drug release system etc.
Polyelectrolytes are primarily utilized in floating processes, thickening and organic sludge dewatering, effluent treatments plants or in waste water plants.
FEATURES OF POLYELECTROLYTES :
- Suitable for any solid-liquid seperation.
- Potent and efficacious even at low dosages.
- Excellent over a wide pH range.
- Maximum flocculation.
