WebApr 5, 2024 · Hundreds of commercial flocculating reagents have been tested singly or in combination with others, in an effort to select a flocculant that will result in the formation of stable flocs that will not reslurry readily … Particles finer than 0.1 µm (10 m) in water remain continuously in motion due to electrostatic charge (often negative) which causes them to repel each other. Once their electrostatic charge is neutralized by the use of a coagulant chemical, the finer particles start to collide and agglomerate (collect together) under the influence of Van der Waals forces. These larger and heavier particles are called flocs.
