Wastewater treatment of industrial enterprises via adsorption method

Abstract

Abstract The publication justifies the feasibility of adsorption method of industrial wastewater treatment from aromatic compounds. Objects and methods of research are described. Studies of adsorption mechanisms of aromatic compounds on bentonites of various modifications made it possible to establish the most effective sorption rock clay-based materials, as well as filter compositions. Bentonite modified with carbon nanotubes after heat treatment 550 ° C proved to be the most effective with respect to the studied aromatic compounds. The principle of combining sorbents in a single filtering system, based on the sorbent selection for various groups of organic pollutants according to their ability to be ionized in an aqueous medium, has been proposed and investigated. Three most effective multicomponent adsorption filter compositions for sewage treatment from nitro and amino compounds were established. The proposed approach is aimed at designing local water treatment stations for industrial enterprises to deal with aromatic compounds via use of multicomponent adsorption filter compositions.
