Publication number: 20240139684Abstract: 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%.Type: ApplicationFiled: January 9, 2024Publication date: May 2, 2024Inventors: John H. BARBER, Wojciech GUTOWSKI, Yongchang ZHENG, Russell James MACDONALD

Patent number: 9790109Abstract: The present invention has the technical effect of disinfecting an EDI device of a water purification system. The present invention may be applied to an EDI device having an internal chamber comprising ion exchange components. The internal chamber may also comprise a plurality of ion selective membranes positioned between the anode and the cathode compartments. As illustrated and described herein, embodiments of the present invention seek to sanitize the EDI device without sanitization chemicals or a water supply. Embodiments of the present invention disinfect the EDI device by applying electrical power. Here an electrical supply device heats the EDI device, through resistive heating of the internal chambers, to a sanitization temperature. The resistive heating is a result of ionic movement through the internal chamber. The friction that is created through the ionic movement increases the temperature within the internal chamber.Type: GrantFiled: April 30, 2010Date of Patent: October 17, 2017Assignee: General Electric CompanyInventors: John Harold Barber, Wojciech Gutowski
