Three types of electrodialysis (ED) and electrodeionization (EDI) stacks are studied when treating NaCl solutions in the range of concentrations from 10−5 to 3 × 10−2 M: (1) with a non-conducting network spacer, (2) with a mixed ion-exchange monolayer bed, (3) with profiled membranes. The Sherwood n

The developed model gives a good agreement of calculated and experimental data. The role of membrane control keeps important even under currents close to the limiting current that gives reasons for improving membrane selectivity properties.

Transport phenomena in Nafion-117 perfluorosulphonic membranes have been studied by different techniques. Membrane electric conductivity has been measured under alternative current as a function of the equilibrating concentrations of MCl (M = Li, Na, K) and HCl solutions. Conductivities were found t

Transport competition between the protons and the alkyl metal cations Li+, Na+, K+ and Cs+ across a cationexchange membrane (CEM), called CMH, was studied in terms of an electrodialysis process with three different configurations: water/water (W/W), solvent/water (S/W) and solvent/solvent (S/S). Und

A review of works resulting in development of a hierarchic system of mathematical models is presented. Different scales of ion transport are considered: 1) in the membrane, where two approaches are used, the irreversible thermodynamics and modelling of the membrane material, the last permits to link
