Flocculation   Wikipedia

Flocculation Wikipedia

Flocculation, in the field of chemistry, is a process in which colloids come out of suspension in the form of floc or flake, either spontaneously or due to the addition of a clarifying agentThe action differs from precipitation in that, prior to flocculation, colloids are merely suspended in a liquid and not actually dissolved in a solutionIn the flocculated system, there is no formation of
