Abstract: A process for electrodialyzing ultrafiltrate and an electrodialysis cell for use in the process are disclosed. The ultrafiltrate contains ionic materials which form a deposit on at least one of the electrodes of the electrodialysis cell impairing the electrical efficiency of the cell. This problem is overcome by removing the deposited electrode from the cell while simultaneously replacing it with electrode relatively free of deposit, thereby restoring the electrical efficiency of the cell. The invention is particularly useful for treatment of the ultrafiltrate of an electrodeposition bath.
