Electrodialysis technology has been widely used in the concentration of high-salt wastewater, and the ion exchange membrane is the core of electrodialysis.In this paper，the basic properties of five concentrated ion exchange membranes was investigated.Intermittent electrodialysis experiments were carried out to investigate the effect of different operating conditions on concentration.The order of Na+ migration rate of different ion exchange membranes was AGC≈FUMATECH>ASTOM>FUJIFILM>YICHEN,obtained by continuous electrodialysis experiments.While the order of energy consumption is AGC≈ASTOM<FUMATECH <FUJIFILM <YICHEN.It is indicated that the AGC membrane has better mass transfer performance and lower energy consumption, which is more advantageous for the pure concentration process.
