“…Clay minerals form a group of layered and layered belt silicates, the particles of which have a clearly expressed crystalline structure and sizes no larger than 0.5-5 microns. The dispersibility of crystals of clay minerals is the criterion that determines their basic physical and chemical properties: sorption ability, ion exchange, catalytic action, thixotropic coagulation structure, i.e., the properties associated with the effective surface of crystals (Petrushka et al 2014).…”

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