ABSTRACT This work is dedicated to development of scientific technologies of sewage water clarification of different industrial enterprises from chrome and nickel ions by the way of adsorption by bentonite from Cherkasy field in dynamic conditions. Perspective and efficiency of application of bentonite clays for clarification of sewage water are confirmed by their advantages before other sorbents, that is: they win in accessibility, cost, and possibility of regeneration and multiple usages. The researches proved expediency of usage the bentonite clays for clarification of sewage water from chrome (III), zink (ІІ) and nickel(II) ions. The static activities have been determined and isotherms of adsorption of nikel, zink and chrome ions have been built. As the most optimal method reset of spend sorbent, deposition by gravity is chosen. Dosage of flocculants allows accelerating the process and increasing the degree of deposition. The basic parameters of the precipitation process of the used sorbent are established. The technological schemes of drain water purification from heavy metal ions contamination were developed; as well as the following sedimentation and regeneration of sorbents.
