Coagulation and flocculation in water and wastewater treatment, 2d ed.9781843391067 Coagulation coagulation (kōăg'y  lā`shən), the collecting into a mass of minute particles of a solid dispersed throughout a liquid (a sol), usually followed by the precipitation or and flocculation flocculation /floc·cu·la·tion/ (flok?u-la´shun) a colloid phenomenon in which the disperse phase separates in discrete, usually visible, particles rather than congealing into a continuous mass, as in coagulation. in water and wastewater treatment, 2d

A flocculent mass formed in a fluid through precipitation or aggregation of suspended particles. [Short for flocculus.] Noun 1. " or "flake" formation from destabilized particles, thus governing their final number concentration) are and have been extremely important processes in water and wastewater treatment. This text brings together theoretical and practical aspects of coagulation and flocculation in a single volume, moving sequentially from principles to applications. In turn, chapters discuss properties of materials present in waters and wastewater; characteristics and types of coagulants commonly in use; mechanisms and practical implications of destabilization of waterborne material using metal coagulants and polyelectrolytes; considerations related to coagulant coagulant /co·ag·u·lant/ (ko-ag´u-lint) promoting or accelerating coagulation of blood; an agent that so acts. co·ag·u·lant n. addition at the rapid mixing stage; theoretical and practical considerations of flocculation; and experimental procedures for assessing primary coagulants, flocculant aids, sludge conditioners, and flocculation parameters. In updating the original 1980 edition, the authors have moved the discussion of the treatment and disposal of sludges resulting from coagulation-flocculation related operations to the appendix.
