Abstract

The limiting current density is of an important parameter in an electrodialysis system, which is the maximum available current density in electro-dialysis procedures. Therefore, it is certainly beneficial to estimate the value of the limiting current density. In this study, the numerical method for estimating the limiting current density is proposed in an electrodialysis with a spacer, which has an important role to mix the ionic solution in term of mass transfer. Moreover, a set of exhaustive experiments for measuring the limiting current density were conducted in order to examine validation of the proposed method. It was found that the present numerical method agrees well with experimental data.
