Destabilisation of colloid particles by addition of a reactive chemical, called a coagulant This happens through neutralization of the charges
the clumping of particles in order to settle out impurities; often induced by chemicals such as lime or alum
Clotting; the process of changing from a liquid to a solid, said especially of blood (i e , blood coagulation)
Clumping of particles in wastewater to settle out impurities, often induced by chemicals such as lime, alum, and iron salts
The process through which individual particles, such as in water, come together to form larger clusters
The process of adding chemicals to water to destabilize charges on naturally occurring particles to facilitate their subsequent aggregation and removal by flocculation or filtration
The sticking together of tiny particles suspended in the water to form bigger particles ('floc') which sink more easily
The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat
Using chemicals (coagulants) to neutralize the electrical charge on fine particles in water, causing them to clump together When clumped, the solids can be separated from the water by settling, skimming, draining or filtering
In water and wastewater treatment, the agglomeration of suspended colloidal particles and/or bacterial cells by the addition of a floc-forming chemical or by biological processes Coagulation is performed to enhance settling of fine suspended particles (Also see flocculation)
Coagulation is generally the change of an albuminous body into an insoluble modification
A pretreatment process used in some desalination plants A substance (e g , ferric chloride) is added to a solution to cause certain elements to thicken into a coherent mass, so that they may be removed
