The electrodialysis process is explained and different ways of moving ions by electrodialysis are presented. ... As shown before, the electrodialysis process takes place inside the cell (stack). The solutions are circulated through the cells from a storage vessel. Each circuit needs a pump, a storage vessel and piping.

Electrodialysis is an electromembrane process in which ions are transported through ion permeable membranes from one solution to another under the influence of a potential gradient. The electrical charges on the ions allow them to be driven through the membranes fabricated from ion exchange polymers.
