Flocculants are polymers with a long polymer chain of carbon atoms along with active groups. The mechanism of action of flocculants is that flocculant active groups can be absorbed on the surface of particles, and in this way, the flocculant chain keeps a large number of particles together in a clot, and a collection of particles is created.
A collection of particles will settle faster than individual particles due to their weight. Flocculants are ionized as soon as they are dissolved in water and according to the functional groups attached to them, they are divided into 3 categories: anionic, cationic and neutral.
Flocculants and coagulants are substances that are widely used to separate solid particles in water.
Flocculants such as polyacrylamide are mainly produced by inverse emulsion or precipitation polymerization.
In the inverse emulsion method, the aqueous solution of acrylamide is dispersed in an oily phase by a suitable emulsifier, and polymerization begins with a water-soluble or oil-soluble initiator.
