Flocculation meaning is a process that helps in forming large aggregates of particles. For this to occur, a chemical coagulant gets added to the liquid. This coagulant facilitates the bonding of the particles in the liquid. According to IUPAC, the flocculation definition states that it is a process of contact and adhesion ...

WebIn brewing, flocculation involves aggregation of dispersed cells into flocs, and occurs towards the end of fermentation. It is characteristic of stationary-phase or late experimental-phase cells of some strains of yeast ( Mill, 1964 ). Both the genotype of cells and fermentation conditions affect flocculation.

WebJul 28, 2011 · Flocculation refers to the accumulation of high molecular weight flocculants on the surface of particles. The destabilization is achieved by reactive cationic or anionic groups and can be controlled by the pH of the suspension. Flocculants are roughly divided into natural organic flocculants (eg starch, glucose) or synthetic polymeric flocculants. WebSpecifically, flocculation, as it applies to brewer's yeast, is “the phenomenon wherein yeast cells adhere in clumps and either sediment from the medium in which they are suspended or rise to the medium's surface.” This definition excludes other forms of aggregation, particularly that of ‘clumpy-growth’ and ‘chain formation’.

WebFlocculation is then used to mean aggregation caused by bridging between particles, usually with long-chain polymers. In this sense, flocculation produces stronger and hence larger aggregates (flocs) than coagulation.
