The Function of Flocculants

Posted on October 14, 2023October 14, 2023 By admin No Comments on The Function of Flocculants

Flocculant is a chemical substance that can form a polymer with a network like structure in water, causing small particles, colloids, organic matter, etc. suspended in water to aggregate into larger clusters, ultimately forming solid matter that can be precipitated or filtered. The following are several different types of flocculants and their effects:

Inorganic flocculants: such as iron chloride, aluminum chloride, etc., can quickly react with load substances in water and generate precipitates, causing them to settle or filter out.

Organic flocculants, such as polyacrylamide and polyaluminosilicate, can aggregate small particles in water through intermolecular forces to form larger particles, ultimately achieving sedimentation or filtration.

Bioflocculants: such as microorganisms, proteins, polysaccharides, etc., can adsorb organic matter and colloidal particles in water and aggregate into larger substances, ultimately forming colloids that are easy to precipitate or filter.

The use of flocculants can effectively remove pollutants such as suspended solids, turbidity, chromaticity, and microorganisms from water, in order to improve the purification effect of water quality. It is widely used in various water treatment equipment and processes, such as water supply and drainage treatment, pure water preparation, drinking water purification, and other fields.
