Abstract

A computer simulation program of ion-exchange membrane electrodialysis is developed for saline water desalination. Inputting the specifications of an electrodialyzer and operating conditions into the program, the following performance of the electrodialyzer is computed. Ion flux and solution flux across a membrane pair; Energy consumption; Salt concentration at the outlets of desalting and concentrating cells; Desalting ratio; Water recovery; Current efficiency; Limiting current density; Current density distribution; Electric resistance of desalting and concentrating solutions and a membrane pair; Electric current leakage; Pressure drop. Constant voltage mode single-pass electrodialysis program is written in the Excel spread sheet and it is integrated in the website. The program in the website can be operated easily with trial-and-error calculation.
