제목 Characterization of Membrane Fouling during Electrodialysis on Pulse Electric Fields
초록 One of the major problems during the electrodialysis (ED) processes is the fouling of ion exchange membranes. In this study, membrane fouling and metal removal in the ED process for electroplating wastewater treatment were evaluated and the effect of electric pulses on fouling mitigation was investigated. Both calcium and magnesium were found to be the major foulants for the cation exchange membranes (CXM). When pulsed electric fields were applied for ED operations, reversible fouling phenomena were reduced. This was because the electric field was able to reverse the movement of potential foulants that may deposit on the membrane surface.
