Flocculation is a process in chemistry wherein colloids are extracted from suspensions which then take the form of flake or floc. They consume a major part of the organic matter of the effluent. The floc typically is held together by a matrix of extracellular polymeric substance (EPS), which may contain variable amounts of polysaccharide, protein, and other biopolymers. n.

Definition of flocs in the Definitions.net dictionary. [1] [2]Applications Surface chemistry. Flocs appear as cloudy suspensions of cells floating in water, rather than attached to and growing on a surface like most biofilms. Floc formation may benefit the constituent microorganisms in a number of ways, including protection from pH stress,[2] resistance to predation, manipulation of microenvironments, and facilitation of mutualistic relationships in mixed microbial communities. flocculation The tendency of yeast to clump together and settle out as fermentation draws to a close.

Flocculation is synonymous with agglomeration, aggregation, and coagulation / coalescence. Flocs are formed from a combination of suspended materials in the raw water together with adsorbed and precipitated solids … ‘This broadens the definition, because many of the self-buoyant microbes and plankton are collected in flocs as well.’ ‘The flocs dispersed immediately when cells were resuspended in a glucose-citrate buffer.’ Term definition.

Flocculation can occur naturally but is also formed from a dispersed colloidal system … Add your answer and earn points. Floc is a flocculent mass formed in a fluid through precipitation or aggregation of suspended particles. What is meant by flocculation? [1] Flocs appear as cloudy suspensions of cells floating in water, rather than attached to and growing on a surface like most biofilms. A colloquial term for the product of a flocculation, that is, the separation of the disperse phase of a colloidal suspension into discrete, usually visible particles, as in certain serologic precipitin tests. Flocculation enhances the agglomeration of destabilized particles and colloids toward settleable (or filterable) particles (flocs). It is characteristic of stationary-phase or late experimental-phase cells of some strains of yeast (Mill, 1964).
