Electrodialysis Treament of Low Concentrations of Wastewater Containing Cu2+

The wastewater contained Cu2+which the concentration ranged from 10 to 50 mg/L are used as the target, to investigated the influences of experiment conditions on the treatment efficiency by electrodialysis enrichment experiments, the authors designed the electrodialysis device, and copper sulfate solutions are used as the objectives. The experiments were investigated when the membrane adsorbed bubbles and removing bubbles, the results show that removing bubbles can improve the efficiency of the concentration and desalination. During the electrodialysis process, the intensity of light chamber has effects on the current intensity, the study in this paper proposed a optimization program for the existing electrodialysis devices.
