REMOVING THE MIXTURE OF DYES AND DISPERSANTS BY APPLYING THE METHODS OF COAGULATION-ELECTROFLOATATION, AND ADSORBTION

Laboratory researches have been realizing on model systems containing textile dyes as basic components, and as auxiliary compounds were used dispersing agents, and polyalcohol. As a result of scientific researches has found that the effect of removal depends on both, the dyes size and the particle charges, as well as the nature, concentration of dyes, dispersants and polyalcohol. Also, wastewaters depend on the time of electro-floatation and the concentration of aluminum ions. Keywords: coagulation-electrofloatation, reactive dyes, direct dyes, dispersing agents, wastwaters.
