Development of Innovative Filtration System for Natural Water Treatment in the Chechen Republic

Abstract

There is a pressing need for high-quality water supply to the population of Grozny. This is due to a specific mixture of salts of heavy metals and lithium, and microbial contamination in the surface water reservoirs. To ensure effective purification of severely polluted surface water, it is necessary to improve filtration systems with a disinfecting effect. The paper describes a method for producing bentonite-and brucite-based sorbent with improved adsorption properties to provide effective water treatment in the Chechen Republic. The authors propose some solutions for combined multilayer filtration systems. The paper presents a method for adsorption water treatment, which implies adsorbing chemical contaminants on mineral granules of high absorption capacity, with a disinfectant to provide an antimicrobial effect. The treatment effectiveness of water from the surface water reservoirs in the city of Grozny, particularly Chernorechensky, Goyta and Sunzha, is assessed in the laboratory with the developed filtration systems. The paper justifies a decrease in color by 96%, turbidity by 99% and 100% iron absorption as well as microbial pollutant extraction using the developed filtration system with improved adsorption properties.
