Abstract

The technological parameters of galvano-coagulation treatment of waste water, containing Cr(VI) and organic colorants, which occur due to the internal electrolysis, are studied. The specifics of iron anodic dissolving, taking place due to the difference of the potentials of galvanic pairs' elements is discussed, as well as the coagulation, sorption, destructive reduction-oxidation processes. These transformations ensure the formation of spinel crystalline sediments with the ferromagnetic properties, which can be utilized in several ways. The advantages of these treatment processes, which can be realized in one and the same reactor, are highlighted. Кeywords: galvanocoagulation, internal electrolysis, catalysis, phase-disperse transformations, ferritization.
