Polyelectrolyte for turbidity removal and clarification
How Sunfloc helps clarifiers clear turbid raw water and effluent, from clean river water to monsoon peaks.
Sunfloc Anionic HQ for regular plant use, or Anionic MQ for smaller plants and trials. Confirm on your own sample with a free jar test.
What turbidity is
Fine clay, silt and organic particles too small to settle on their own. They carry a surface charge that keeps them apart, which is why the water stays cloudy.
Coagulant, then polymer
A coagulant neutralises that charge so particles start to clump. A small dose of Anionic HQ or Anionic MQ then bridges the clumps into heavy flocs that settle in the clarifier.
How dose follows turbidity
Clean water below 20 NTU may need only 0.1–0.3 mg/L of an anionic grade; water above 100 NTU can need 0.5–1.5 mg/L. The dosing guide has the full table.
Monsoon peaks
Raw water turbidity can jump overnight in the rains. Re-run the jar test when it changes, and raise the dose in steps rather than all at once.
Signs it is working
Large flocs within a minute or two of slow mixing, a clear layer forming above them, and lower turbidity at the clarifier outlet.
