Abstract

Under this condition of direct current (DC), according to the property that ion electromigration happens on the external electric field, mathematical modeling for desalination by electrodialysis (ED) was established on the basis of NaCl separation experimental data. The mathematical modeling started from a differential equation of steady-state mass balance, derived the equation and was validated by experiments. The model parameter was determined by the experiment data. The model gives concentration of dilute compartment for various voltages, flow rates and feed concentrations. According to comparing predicted data with experimental data, it was found that there is a good consistency between the experimental and calculated data and the mathematical modeling could be used to well predict the process.
