Abstract
Electrodialyzer equipped with a segmented electrode was used for a desalination of a model sodium chloride solution in the diluate linear flow velocity range of 2.11-3.37cm/s, concentrate linear flow velocity range of 0.38-0.70cm/s and current density of up to 722A/m2. The observed current density distribution, concentration and velocity changes allowed for the establishment of the concentration and linear flow velocity distributions along the concentrate and diluate compartments, taking into account the solute diffusion and electromigration, the solvent osmotic and electroosmotic flux and the solvent-solute interactions. The influence of concentration distribution and concentration polarization on the gypsum scaling risk was discussed.
