Pumps for coagulating agents (from lat. coagulo - cause coagulation, thickening), substances whose introduction into a liquid medium containing small particles of a body causes coagulation, i.e., sticking together of these particles. Under the influence of K., large accumulations of stuck together particles are formed, which precipitate in the form of flakes or lumps (coagulate).
Salts of polyvalent metals (aluminum, iron, etc.) are effective crystals for systems with an aqueous dispersion medium. Water-soluble organic macromolecular compounds (polymers), especially polyelectrolytes, are also used as electrolytes. Unlike inorganic crystals, they are sometimes called flocculants and are used to isolate valuable industrial products from production waste in various technological processes, as well as in the purification of water from natural and household contaminants.
