FlocculationWikipedia
Flocculation in the field of chemistry is a process by which colloidal particles come out of suspension to sediment under 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 under the form of a stable dispersion in a liquid and are not truly dissolved
