The basic principles of electrodialysis are reviewed with special emphasis on the efficiency of energy utilization. Methods suggested in the literature for minimizing the polarization and its adverse effects are described. This includes the use of polarity reversal, ion-conducting spacers, ion-exchange resins between membranes and heterogeneous membranes. Effect of raising the temperature in decreasing power consumption leading to the development of HTED is discussed.Attempts to desalinate sea water by ED are also mentioned. Turning to solar application it is found that when DC power is being produced by PV generators the use of ED is most appropriate while when both DC and AC are available from solar sources a combination of RO and ED becomes an obvious suggestion.
