Electrodialysis (ED) is used to remove ionized substance from hquids through selective ion-permeable membranes. ED is the most widely commercialized electromembrane technology. Desalination of brackish water is the area of electrodialysis application with the largest number of installations. This chemical-free technology competes with reverse osmosis. Electrodialysis shows better resistance to fouling and scaling. It also has an economical advantage in desalination of low-salinity solutions [13]. Also, it should be kept in mind that because of small material consumption ED is the most environmental friendly process for solution desalination [14]. 

Of special note is the electrodialysis application for solution desalination in organic synthesis. For example, electrodialysis with ion-exchange membranes based on polystyrene and polyethylene for HCl removal from solution in chlor-hydrin synthesis is reported [2]. It is possible to get 1 N HCl from 1-3.5 g/1 so-... 

Ion-exchange membranes were first developed for electrodialysis applications such as desalination of seawater or brackish water, where an impure stream is elecbolyzed in a dialyzer consisting of an anode and cathode assembly, between which a stack of anion and cation-exchange membranes is placed. During electrolysis, the field across the membranes allows the transfer of anions and cations, thereby producing dilute and concentrated brine streams.
