Study of Mathematical Model in Electrodialysis of Desalination

Abstract

This paper presents experimental data and mathematical model for a laboratory scale electrodialysis (ED) cell. Mathematical model for desalination by electrodialysis (ED) was established on the basis of NaCl separation experimental data. The mathematical model 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. Comparing predicted data with experimental data, excellent agreement between the experimental data and the model results indicates the capability of mathematical model to predict the desalination process.
