ELECTRODIALYSIS OF DILUTE ELECTROLYTE-SOLUTIONS - SOME THEORETICAL AND APPLIED ASPECTS

Conventional techniques for enhancing electrodialysis efficiency of di lute solutions are considered. The techniques in question involve inse rting separators of different designs in the membrane channels and red ucing the intermembrane distance. The possibilities for utilizing conj ugated ''side'' effects, which accompany electrodiffusive transport of salt ions in membrane systems at currents exceeding the overlimiting values, are discussed. Examples of practical electrodialysis applicati on for producing deionized water are reported.
