An Insight into Electro-dialysis for Water Treatment (original) (raw)

Electro-dialysis is used for treatment of industrial wastewater. In this method ion selective membranes separates compartments of the electro-dialysis tank and two ends of the tanks are equipped with positive and negative electrodes. The ions to be separated move towards opposite electrodes. The factors such as initial concentration, applied voltage and temperature affect the performance. Desalination of water for reuse and recycle is purpose of treating water by electro-dialysis. Investigations are reported on electro-dialysis for exploring possibilities of different electrodes, membranes and optimizing operating parameters. Current review summarizes research and studies on electro-dialysis.
