Drinking water samples taken in houses and apartments in the territory of Kazan showed polymetallic contamination. In the article the possibility of using zeolite-containing rock of the Tatarsko-Shatrashansky deposit for additional treatment of drinking water from metals coming in the course of passing through water pipelines and branch lines is investigated. A series of experiments on development of methods of modification of zeolite-containing rock of Tatarsko-Shatrashansky deposit was carried out. The most effective ways of modification were proposed. Three samples of filter material were developed: natural prepared zeolite, zeolite modified with acid and zeolite treated with salt. The effectiveness of the filter materials was evaluated by comparing the concentrations of metals before and after contact with the developed filter material samples. Metal concentrations before and after treatment with the filter material samples were analyzed by atomic absorption spectrometry. Sorption efficiency of separate samples of zeolite-containing rock in relation to aqueous solutions of zinc, lead, copper, and chromium was evaluated. The calculation of sorption efficiency showed the efficiency of purification by filter material based on natural zeolite, prepared mechanically from lead ions - up to 98% and copper - up to 93%, but the use of this filter material gives a large amount of suspended solids. Zeolite modified with HCl also showed high efficiency of purification from copper ions - 96% and lead ions - 94%. The filter material based on zeolite modified by NaCl solution showed high efficiency of purification from zinc ions - up to 81%, copper - up to 94% and lead - up to 86%.
