"WebFlocculation is a two-step particle aggregation process in which a large number of small particles form a small number large flocs. Step 1: Coagulation Small particles usually carry negative surface charges that hinder aggregation and settling (1a). Coagulant chemicals can adsorb to the particles and balance the charges.

WebFeb 1, 2001 · Since flocculation is a process of aggregation, its performance should be directly measured in term of aggregate (floc) size distribution. The objectives of the study described in this paper were to describe the evolution of floc size distributions under different conditions and to evaluate flocculation mechanisms using the size distributions ... WebFlocculation is then used to mean aggregation caused by bridging between particles, usually with long-chain polymers. In this sense, flocculation produces stronger and hence larger aggregates (flocs) than coagulation. Since aggregates have fractal character, and their density decreases with increasing size, those produced by polymers tend to ...
