The efficacy of flocculation for any given process depends on the nature and concen …
WebMar 27, 2009 · Fine silt soils are not flocculated by calcium hydroxide on account of the inefficiency of the relatively small amount of “emulsoid” clay to protect the large “suspensoid” surface exposed by the fine silt. Type. Research Article. Information. The Journal of Agricultural Science , Volume 10 , Issue 4 , October 1920 , pp. 425 - 436. 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 eutrophication due to the ads…
