Abstract

Сoagulant was obtained from waste alumina production ("red mud"). The analysis of samples of "red mud" and activated with sulfuric acid forms, set their phase and elemental compositions. On the basis of analysis identified physical and chemical laws of acid activation of "red mud"; established the conditions for obtaining reagents from the "red mud", which are expressed coagulation properties. The high efficiency of the application of the modified "red mud" as a coagulant for wastewater from dye "active bright blue" with the concentration of 10 mg/dm3. The degree of purification is 95 %.
