ABSTRACT:
The method and apparatus for rinsing an electrodialysis electrode provides isolation from the fluid being electrodialyzed. The method utilizes the natural circulation of the liquid and provides an exchange between the anode and cathode liquids while maintaining electrical isolation to thereby improve the efficiency of the electrodialysis cell and reducing the power requirements. The method of rinsing makes use of the gas generated at the electrodes to provide a motivating fluid for circulating the electrode rinse liquid. Circulation of the fluid is carried out in the slug flow region to provide electrical isolation. In the multi chamber apparatus the chamber adjacent to both of the electrode chambers contains the dilute liquid and is positioned between the electrode chamber and the chamber containing the concentrated solution to prevent migration of ions from the concentrated solution into the electrode chamber to contaminate the electrode.
