Abstract: This paper presents experimental data and predict the cell behavior. The assumption was given to
mathematical model for a laboratory scale electrodialysis (ED) establish the mathematical modeling: (1) quasi-steady state; (2)
cell. Mathematical model for desalination by electrodialysis (ED) negligible electro-osmosis transfer; (3) pressible fluid;
was established on the basis of NaCl separation experimental (4) this ion exchange membrane was ideal film and had ideal
data. The mathematical model started from a differential selectivity for the ion transport; (5) this solution only
equation of steady-state mass balance, derived the equation and contained salt of sodium chloride.
was validated by experiments. The model parameter was In reference [4], we made a series of experiments
determined by the experiment data. The model gives based on the same assumption above mentioned. The
concentration of partment for various voltages, flow
rates and feed concentrations. Comparing predicted data with mathematical model of literature was further verified using
