    • 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 agent. The action differs from precipitation in that, prior to flocculation, colloids are merely suspended in a liquid and not actually dissolved in a solution .

It can be described as a physical or a mechanical process in which the coagulated clumps are made to join
