floc characteristics in water and wastewater treatment

FLOC CHARACTERISTICS IN WATER AND WASTEWATER TREATMENT

The behavior of an aggregate of colloidal particles, or floc, in a water treatment process is dependent upon its physical characteristics, including size, strength, density, and permeability. It is no exaggeration to say that the success of a water treatment operation can be gauged by the properties of the aggregates produced.

Characterization of ballasted flocs in water treatment

Ballasted flocculation is widely used in the water industry for drinking water, municipal wastewater, storm water and industrial water treatment. This gravity-based physicochemical separation process involves the injection of a ballasting agent, typically microsand, to increase the floc density and size.
