Abstract：

Sulfonated poly(phthalazinone ether ketone) membrane was used as cation exchange membrane for electrodialysis. The effects of volume ratio, flow rate and operation current on desalination of low concentration solution and concentration of high concentration solution were investigated. The results showed there were no significant influence on desalination of low concentration solution and energy consumption, when the volume ratio of the concentrate cell to the dilute cell increased from 1:1 to 3:1. However, the final concentration rate for high concentration solution increased from 94% to 201%, when the volume ratio of the concentrate cell to the dilute cell changed from 1:1 to 1:3. As the flow rate increased from 20 to 60 mL/min, the desalination rate of low concentration solution decreased from 76% to 71% at 105 min, while the final concentration of high concentrated solution increased from 191% to 223%. The desalination rate of low concentration solution and concentration rate of high concentration solution increased with an increase in operating current (0.1-0.18 A), but energy consumption would be increased.
