WebJul 28, 2011 · Flocculation refers to the accumulation of high molecular weight flocculants on the surface of particles. The destabilization is achieved by reactive cationic or anionic groups and can be controlled by the pH of the suspension. Flocculants are roughly divided into natural organic flocculants (eg starch, glucose) or synthetic polymeric flocculants.
