Introduction

Desalination is considered as a common solution for the regions with shortage of fresh water resources. There are various methods for brackish and sea water desalination. PNF Company has developed modified electro dialysis technology as an appropriate and efficient for desalination.

The developed process is an electrochemical technique in which the ionic contaminants are removed from the aqueous solution. In this method, separation of salt from water is conducted in the presence of anionic and cationic membranes under the influence of an electric field.
