Electrodialysis for the removal of copper ions from wastewater

Abstract

In this work,the feasibility of the removal of Cu2+ ions in a model solution and a sample of rinse water have been studied using a recirculating electrodialysis system. Full removal of Cu2+ has been achieved from its dilute solutions and the sample of rinsewater provided from a local plating plant depending on duration of electrodialysis,applied voltage and flow rate while recovering of copper by forming concentrated copper solution in the cathode compartment. Thus, another aspect of this process is to be able to concentrate rinsewater up to the bath strength.
