Coagulation and Flocculation Process Fundamentals 1 Coagulation and Flocculation . Groundwater and surface water contain both dissolved and suspended particles. Coagulation and flocculation are used to separate the suspended solids portion from the water. Suspended particles vary in source, charge, particle size, shape, and density. Correct ...

Flocculation process is the opposite of dispersion that means colloidal particles tend to attract each other and coagulate like a bigger particle caused by a decrease in zeta potential (ζ) and hydration. The condition of flocculation is generally beneficial in the formation of good soil structure.

May 01, 1973· Flocculation with cationic polyelectrolytes requires tess rigorous control of pH for efficient opera tion than flocculation with alum. SUMMARY Light absorption and electrophoretic mobility measurements were used in the study of the effect of temperature on flocculation of kaolinite and bentonite clay dispersions in water.

Electrolytes enhanced the adsorption of anionic polyacrylamide chains on negative bentonite surface, while hindering adsorption of cationic polyacrylamides. Electric double layer compression and mediated flocculation by metal cations were the principle mechanisms involved in the improvement of flocculation behavior.
