This work is dedicated to development of scientific technologies of wastewater purification of different industrial enterprises from chrome ion by the way of adsorption with the help of bentonite from Cherkasy field in dynamic conditions. Perspective and efficacy of bentonite clays application for wastewater purification are confirmed by their advantages over other sorbents, that is: they win in accessibility, cost, and possibility of regeneration and multiple usages. The level of wastewater purification during adsorption with a stationary sorbent layer under static conditions and under conditions of perfect mixing at different concentrations of chromium ions (III) and quantities of the dosed sorbent was determined. The significant difference in the purification level ranges from 70÷87 % and is more dependent on the stock concentration of chromium ions. It has been found that the purification time of the same volumes of solutions for low concentrations is almost two times shorter under constant stirring, and of the same level at the stock concentrations of 1500mg/dm3. The technological schemes of wastewater purification from heavy metal ions contamination were developed.
