At acting the various kinds of nonequilibrum electrical discharges on ceolits there is increase them adsorption ability. It allowed to use them for purification the waste industrial waters of Mingechaur “Azerelectroizolit” plant containing sulphates, chlorides, nytrates, nytrides, oil products and also phenol being strongly harmful substance and most danger at ingressing into flotation. The plant waste water were purified in laboratory conditions. Before purification ceolit was subjected to activation effect by the barrier kind of electrical discharge during 30 minutes. The chemical analysis of purified water has shown significant reduction of harmful impurities content on-comparison with initial water. According to results of laboratory researches the purification works project for “Azerelectroizolit” plant was offered and developed.
