coagulation and flocculation in water and wastewater

Coagulation and Flocculation in Water and Wastewater

In modern water treatment, coagulation and flocculation are still essential components of the overall suite of treatment processes – understandably, because since 1989 the regulatory limit in the US for treated water turbidity has progressively reduced from 1.0 NTU in 1989 to 0.3 NTU today.

Coagulation: These two layers around the particle cause it to be stable in the water. When the conditions within the water are changed e.g. by a change in pH or conductivity the amount of ions in the water changes well. This change in ions in the water will affect the amounts of ions in the two layers and thereby affect the stability of the
