“…Using the results of our research, we can propose a technological scheme of sewage treatment on the basis of a natural sorbent -bentonite -in full cycle (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Such a principle scheme for purifying the liquid waste of the galvanic line, or sewage after the tanning of leather production is given in Fig.…”

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.

“…For example, due to full goaf stowing, methane flow into the breakage face from the mined-out space is sharply reduced and the probability of endogenous fires is completely eliminated, the intensity of the inrush formation process is reduced, and the state of the water resources of coal mining regions is improved [14,40]. However, this experience was not continued due to increased labour intensity of work, reduced load on long face and the lack of incentives to improve the quality of extracted coal.…”

The ecological consequences of long-term development of coal deposits for the components of the environment, buildings, communications and infrastructure facilities have been analysed. The stress-deformed state of the rock massif around the preparatory working in the development of multiple coal layers is determined. The parameters of the development of the contiguous layers in the conditions of the mines of the Lviv-Volyn Coal Basin are substantiated. The complex of nature protection measures allowing to reduce the negative consequences of disturbance of the earth’s surface in the development of multiple coal layers is substantiated.

“…Therefore, the creation of effective sorbents (involving agro-industrial wastes) and their practical application for adsorption purification technologies is one of the priority directions of the technical support of environmental safety 1 Kremenchuk Mykhailo Ostrohradskiy National University, 20, Pershotravneva St., 39600 Kremenchuk, Ukraine * sefira@mail.ru 2 Lviv Polytechnic National University, 12, S.Bandery St., 79013 Lviv, Ukraine ã Shmandiy V., Kharlamova O., Malovanyy M., Bezdeneznych L., Rigas T., 2020 [11,12]. The urgency of the research is stipulated by the necessity to find new ways to improve the quality of adsorbents, reduce the anthropogenic load on the water basin and follow the quality standards of hydro ecosystems [13].…”

A multi-stage method for producing an absorbent with increased absorption capacity based on agro-industrial wastes has been proposed. The method includes treatment of raw materials with sulfuric acid, mechanochemical modification, electrostatic separation, and cavitation stage. The expediency of the proposed adsorbent usage in the process of purification of contaminated water from fats, phenols, petroleum products, and heavy metal ions has been proved. The complex application of adsorbents (absorption of gaseous pollutants and wastewater purification) has been tested. Adsorption properties relative to pollutants extraction were found to be better for obtained adsorbents compared with natural absorbents and activated carbon.
