✦ Synopsis

Electrodialysis is used here for concentrating dilute solutions of zinc sulfate. Product concentration is Limited by salt flux and water transport, i.e. hydration water, and osmotic. electroosmotic fluxes. Then, the variation in concentration of the concentrate solution can be expressed by a relation of the form: where the variable x is either the surface, or the number of elementary compartments. It can also be the time, or the current density. Optimization with respect to time shows that hi concentration factors are obtained with an apparatus for which the product of the exchange area to the inverse of the channel width is high. Experimental results agree with this analysis in the case of ZnSO~ aqueous solutions.
