Overlimiting current
WebThe effect of successive limiting current density (LCD) determination procedures on electrodialysis with ultrafiltration membrane (EDUF) system was studied in order to evaluate their impact on ion-exchange (IEM) and ultrafiltration membranes (UFM) integrity by measuring in situ the membrane potential difference. In the first protocol, two successive … Weboverlimiting currents are applied solely in electrodeionization, and not in conventional ED devices. In literature (H. Strathmann [1]), overlimiting current density operation ED is …
