Flocculants an overview ScienceDirect Topics
Most commercial flocculants are synthetic water soluble polymers with average molecular weights in the region 1000 to 30 × 10 6.They are generally supplied as powders that have a limited storage life, particularly when made up into solution. While there is an understandable reluctance for manufacturers to divulge their exact chemical nature, it is known that the majority of polymer
FlocculationOverviewApplicationsTerm definitionDeflocculationSee alsoFurther reading
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 to the top of the liquid (creaming), settle to the bottom of the liquid (sedimentation), or be readily filtered from the liquid. Flocculation behavior of soil colloids is closely related to freshwater quality. High dispersibility of soil colloids not only directly causes turbidity of the surrounding water but it also induces eutrophicationdue to the adsorption of nutritional substances in riv
