Efficient treatment of wastewater from galvanic plants

Abstract

Abstract The article discusses a promising method for the purification of chromium-containing wastewater from galvanic plants. A review and comparative analysis of existing methods and technologies for treatment of industrial waste from various organochromium compounds, such as reagent-based, biological, ion-exchange and others, are presented. The advantages of using the combined method of chromium-containing wastewater treatment based on electroflotation with preliminary electrocoagulation are shown. The effectiveness of the proposed combined method is evaluated and the design of electroflotocoagulator is developed.
