A desalting system making use of electro-osmosis is similar to conventional electrodialysis arrangements in that the input solution is passed between a pair of membranes one of which is anion permeable and the other cation permeable, an applied electric field causing the anions and cations to leave the solution by migrating through the respective membranes. However, unlike conventional electrodialysis membranes, the membranes are also relatively permeable to water. The resulting flow of water toward and through the membranes materially increases the rate at which ions are transported to the membranes and correspondingly increases the rate at which ions are removed from the input solution.
