Separation indexes following coagulation and flocculation.

Coagulation and flocculation followed by removal of floccules by flotation aided by dissolved air

Where coagulation and flocculation treatment is required the preferred form of conditioning method is with the use of a limestone contactor.

Sludge containing colloidal substances should be previously destabilized by coagulation and flocculation, according to already described techniques.

Coagulate, Flocculate For water purification or effluent treatment, fine solids suspended in water can be agglomerated and removed by coagulation and flocculation with agents such as lime, FeCl3 and polymers.
