What is flocculation?
Flocculation refers to the clumping of yeast cells at the end of fermentation. Strains are separated into three main degrees of flocculation- High, Medium, and Low. An example of a highly flocculent strain would be our English Ale yeast, which will settle at the bottom of the fermentation tank. An example of a low flocculent strain would be our Hefeweizen yeast.
Flocculants by definition means a process in which individual particles of a suspension form aggregates. In the water treatment industry, the terms coagulation and flocculation imply different mechanisms. Flocculants consist of various molecular weight anionic, nonionic and cationic polymers. They are used to increase the efficiency of settling, clarification, filtration and centrifugation operations.
FLOCCULATION is used to describe the action of polymeric materials which form bridges between individual particles. Bridging occurs when segments of a polymer chain adsorb on different particles and help particles aggregate. Flocculants carry active groups with a charge which will counterbalance the charge of the particles. Flocculants adsorb on particles and cause destabilization either by bridging or charge neutralization.
It is the process of gently mixing the water and coagulant, allowing the formation of larger particles of floc. In a treatment plant, flocculation is achieved through a slow and gentle mixing of the coagulated water, generally in paddle flocculators.

Flocculation refers to the separation of a solution. Most commonly, flocculation is used to describe the removal of a sediment from a fluid. In addition to occurring naturally, flocculation can also be forced through agitation or the addition of flocculating agents. Numerous manufacturing industries use flocculation as part of their processing techniques, and it is also extensively employed in water treatment. The technique is also widely used in the medical world to analyze various fluids. The term is derived from floc, another word for flakes of material. When a solution is flocculated, the sediment in the material is formed into clumps of aggregate which are easier to see. When flocculation is initiated intentionally, the floc is usually removed with filters or screens. When a solution was flocculated by accident, attempts may be made to turn it back into a solution so that it will be usable again. The technique of flocculation can be used to separate out visible sediments and mater
