Abstract

 Capacitive ionization is one of the membrane methods available for water desalination that works based on ion exchange. In capacitive ionization systems, saline water passes through a cell that has electrodes with a high contact surface. By applying a voltage, the ions are absorbed under an electric field on the surface of the porous electrodes, as a result of which the salinity of the water is reduced and freshwater is removed from the other side of the system. Recently, researchers have proposed various models for predicting the behavior of desalination plants by capacitive deionization. The model used for the simulation is a one-dimensional transfer equation based on the transfer theory of porous and ball-Chapman-Stern electrodes to predict the output water concentration and identify the parameters affecting the performance of the capacitive ionization system. This study aimed to investigate the water desalination efficiency using changes in the operating parameters of capacitive ionization systems. The parameters studied in this study included fluid flow, applied electric current, input concentration, porosity, electrode cross-section, and electrode length. The results showed that the most effective parameter in improving the performance of the device is applied electric current so that with a fifty percent increase in applied electric current, the percentage of water desalination increased by about 72%, and the time required to achieve maximum water desalination decreased by about 76%.
