Recently, electrodialysis technology has received widespread attention in the fields of water resource utilization. The core of the electrodialysis technology is the structure and performance of the ion exchange membrane. This study uses the single variable method to investigate the effects of energy consumption, current efficiency, and other parameters of homogeneous and heterogeneous membranes, then by chemical analysis method and scientific numerical analysis to determine the best operating parameters for the electrodialysis process of different ion exchange membranes. The experimental results show that the current efficiencies of heterogeneous and homogeneous membrane can reach 0.9295 and 0.9577 respectively. The highest concentration in the concentration chamber by using heterogeneous and homogeneous membrane can reach 149.30 g/L, 191.24 g/L, respectively. Meanwhile, the structural stability of the two ion exchange membranes was compared by concentration experiment and system stability analysis. These experimental results indicated the direction of homogeneous and heterogeneous membrane in electrodialysis engineering.
