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 … See more According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters". Flocculation is synonymous with agglomeration and … See more Surface chemistry In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float … See more • Algaculture – Aquaculture involving the farming of algae • Clay–water interaction – Various progressive interactions between clay minerals and … See more Deflocculation is the exact opposite of flocculation, also sometimes known as peptization.
