Treatment of Industrial Wastewater from Copper Ions by Sorbent on the Basis of Vegetable Wastes

The composition of galvanic production wastewater and the technological scheme of its purification are studied. It is shown that the concentration of copper cations after treatment exceeds the level of maximum permissible concentration (MPC) for fishery water bodies. The process characteristics of dried vegetable wastes and ash generated as a result of their combustion in the boiler are obtained, as well as the parameters of the boiler itself are calculated. The adsorption process of copper ions from model solutions by two types of sorbents under static and dynamic conditions was analyzed. The process scheme of wastewater treatment from copper ions at the production of the company “ELTONS” was improved by adding a block of additional treatment with sorption material based on vegetable waste ash. The possibilities of utilization of the spent sorption material are noted.
