Abstract: The present disclosure provides an electrodialysis stack that may be used for the treatment of an electrically conductive solution. The stack includes two electrodes (at least one is a recessed electrode), a plurality of ion-transport membranes and stack spacers. The membranes and spacers are arranged between the electrodes to define electrodialysis cell pairs. The stack includes an electrically insulated zone that extends substantially from a distribution manifold past the recessed edge of the electrode and substantially from the recessed electrode to the opposite electrode for a distance that is about 8% to 100% of the total distance between the electrodes. The overlap distance that the electrically insulated zone extends past the recessed edge of the electrode is calculated as: distance in cm=(0.062 cm−1)*(exp(−60/total cp)*(area in cm2 of the manifold ducts of the concentrated stream at the recessed edge)+/−10%.
