Coagulation And Flocculation in Water Treatment Explained

WebAn equation is derived in which the particle concentration is expressed as a function of both the rate of flocculation and the rate of coalescence, and the time of coagulation. The rate of coagulation appears to depend upon the particle concentration, in such a way that the rate of increase of 1/n increases with decreasing initial particle concentration. WebThe flocculation mechanism was determined via particle size distribution and zeta potential analysis. The optimum conditions for the improved bioflocculant production were as …
