Flocculation Making clean water (video) Khan Academy

Flocculation is the process in which colloids aggregate, or come together, to form larger particles called flocs by the addition of a chemical called a flocculant. Typical flocculants units include alum and ferrix, because they work well with high turbidity fluid mixtures. Now, let's demonstrate how flocculation works.
