• flocculation

    Flocculation

    Flocculation, in the field of chemistry, is a process in which colloids come out of suspension in the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from precipitation in that, prior to flocculation, colloids are merely suspended in a liquid and not actually dissolved in a solution .

Aluminum sulfate is a white, solid (powder) with a chemical formula of Al2(SO4)3. It is an ideal choice to use as a flocculant because when it dissociates in water, it forms a high amount of charged compounds, as shown in Figure 4. Another common flocculant is polyacrylamide. Polyacrylamide is a polymer, meaning it is made of many (poly) parts (mer). The name
