coagulation (water treatment)

Coagulation (water treatment)

Coagulation-flocculation process in a water treatment system. In water treatment, coagulation flocculation involves the addition of compounds that promote the clumping of fines into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge.

Inorganic coagulants are particularly effective on raw water with low turbidity and will often treat this type of water when organic coagulants cannot. Once added to water, the inorganic coagulants form aluminium or iron precipitates. These absorb impurities in the water as they fall, serving to clean the water.
