Abstract: The composition of wastewater from galvanic production and the technological scheme of their purification have been studied. The technological characteristics of dried plant waste and ash obtained after their combustion in a boiler with energy production are determined. The characteristics of the boiler during the combustion of plant waste are calculated. A technology for the production of granular sorbent from the ash of plant waste has been developed. The cleaning system has been supplemented by adding a post-treatment unit with the resulting sorption material. The filter has been calculated. The results of the study make it possible to obtain a new material for sorption purification from copper cations, up to the level of maximum permissible concentration of harmful substances discharged into fisheries reservoirs. After examining the mechanism of adsorption, it was found that physical adsorption occurs. To determine the nature of adsorption, the Gibbs energy was calculated, the rate constants of the adsorption equilibrium were calculated, and the activation energy of the process was calculated.
