摘要
Abstract: Literature data of domestic and foreign research works concerning the use of aluminum-containing sludge obtained in the course of drinking-water treatment as a sorption material for the removal of pollutants (ions of various metals, dyes, oil and the products of its processing) from aqueous media are systematized. Literature information on the composition of water-treatment wastes is given. Information is briefly presented concerning the studies on aluminum-containing water-treatment wastes as a sorption material for As(III) and As(V), Cd2+, Cr(VI), Co2+, Cu2+, Hg2+, Mo(VI), Pb2+, Sb(V), Se (IV), Se(VI), and Zn2+. It is shown that the water-treatment sludge containing aluminum compounds therein is an efficient sorption material for phosphorus compounds, including phosphate ions, which can be used to reduce the eutrophication of natural aquatic reservoirs. Information is also presented concerning the potentialities of petroleum products from water-treatment sludge taken from aquatic environments. It is shown that it is quite possible to provide an increase in the sorption characteristics for different pollutants through the treatment with the use of various chemical reagents. © 2023, Pleiades Publishing, Ltd.
