COAGULATION AND FLOCCULATION

Wastewater flows into a reactor (flocculator) where it is mixed with chemical reagents to make the small suspended particles capable of sticking together (coagulation) and to aggregate thus producing larger, visible flocs (flocculation). The common reagents are: mineral and/or organic coagulants, flocculation additives (activates silica, talcum, activated carbon), anionic or cationic flocculants and pH control reagents such as acids or bases.

Wastewater contains particles of different sizes which can be classified as dissolved (<0.08-1um), supra-colloidal (>100-100mm) and settleable (>100um). The goal of wastewater coagulation and flocculation is to create a system which can successfully separate dissolved and suspended particles of different source, size, shape, charge, and density from water.

Technology of wastewater coagulation and flocculation include combination of a tank- or pipe-shaped reactor (flocculator) and pumps/valves to ensure very precise dosage of chemical reagents.
