Flocculation in gases and liquids

Flocculation of fine particles in gases or liquids plays an important role in industrial environmental control systems. Solid particulate contaminants are often so small that their removal from liquid or gaseous effluents is not economically possible. The agglomeration of these solids into sometimes rather loose larger floes , conglomerates, or strings of particles facilitates removal with conventional, economic environmental control devices. [Pg.413]

For technical applications, electrocoagulators are used to charge the solids in contaminated liquid effluents. Metal hydroxides are produced by a system of soluble electrodes (anodes) which, in suitable electrolytes, cause coagulation of particles into larger floes. [Pg.416]
