Addition of treatment chemicals forms precipitates and allows neutralization of surface charge on colloidal particles (coagulation). The small particles thus formed settle slowly Flocculation is the gentle agitation which allows small particles to...

Flocculation is a process where a solute comes out of solution in the form of floc or "flakes." The term is also used in colloid chemistry to refer to the process by which fine particulates are caused to clump together into floc. The floc may then float...
