The article presents a technique of the granulated sorption material production based on the chemical water treatment slurry. The sorption has been studied in statical and dynamic conditions. The sorption effectiveness by copper ions was 90.5 %. The isotherm of adsorption and a curve of adsorption in dynamic conditions of cations of copper has been plotted by the granulated material. During the experiment the dynamic exchange capacity, full exchange capacity of the granulated material has been determined. The filtrate quality indicators in water passage through sorption material loads in accordance with MPC of domestic drinking and recreational purposes water bodies. The granulated sorption material extract was tested for acute lethal toxicity for Poecilia Reticulate Peters fish and Daphnia Magna Crustacea. The obtained results affirmed that the granulated sorption material was not practically hazardous and did not bring secondary pollution to wastewaters. The authors have presented a technological scheme of electroplating wastewaters ion-exchange treatment.
