Decription:
Flocculants are charged polymers used in industry for clarifying suspensions. They cause suspended colloi
dal matter to aggregate, forming particles that are large enough to settle out under gravity.

Both cationic polymers (
containing positive charges) and anionic polymers (containing negative charges) are used for different applications.

A
typical anionic flocculant is a copolymer of acrylamide and acrylic acid, made by inverse emulsion polymerization.

Th
e essential mechanisms by which flocculants work are charge neutralisation and bridging.

Charge neutralisation allows
particles to get closer to each other by reducing the electrostatic interactions between them - when they can approach more closely, they can join together coagulate).

Bridging flocculation involves polymer chains sticking to multiple particles,
making an aggregate large enough to settle out.
