Abstract
An electrode reversal system for an electrodialysis cell is disclosed in which acidic anolyte produced in the anode chamber is collected and simultaneously recirculated through both the anode and cathode chambers. The cathode effluent is removed from the cell and on reversal of electrical polarity, the hydraulic flow paths to and from the chambers are reversed.
