摘要：In Saudi Arabia, availability of safe drinking water is a burning issue due to high salinity of groundwater used for various purposes. The main objective of this study was to study saline water desalination by a batch containing 3-compartment electrodialysis cell under local conditions. The experimental treatments were the initial concentration of sodium chloride (NaCl) solution in the system and the position of anode electrode and cathode electrode in the compartment with respect to the ion exchange membranes. The relationship between the I and V was very poor with a value of around 3 V and became almost linear when the V increased from 3 and above in the electrodialysis cell used for desalination. It was found that only limited current (amperes) reached to anode and cathode compartments especially when the saline solution was highly concentrated in the middle compartment of the batch containing 3-compartment electrodialysis cell. It was suggested to redesign the electrodialysis cell with 4-compartments instead of 3-compartments with a reduced size of the cell, to avoid its adverse effect on the path of desalination process. The study findings suggested more elaborated investigations using waters of different salt concentrations for system efficiency.
