Effect of temperature on the desalination process by electrodialysis
Original language description
Electrodialysis (ED) is a significant method in saline water desalination and industrial wastewater treatment. Ion exchange membranes (IEMs) are an important part of the electrodialysis process. An ion-exchange membrane is a semipermeable membrane that transports ions through an oppositely charged membrane and blocks the passage of a co-ion under an electric field. Temperature changes in ED systems may increase ion transport selectivity and charge separation efficiency. The rate of ions transport depends on the number of ions diffusion toward the membrane. This works describes the effects of feed and its operating temperature on different IEMs in an electrodialysis system. It is concluded that the increase in temperature and voltage are parameters that positively affect the salt removal efficiency of the EDR process. It was found that voltage 1 V per pair and feed temperature 60 °C are the best combination of operating parameters to achieve the highest salt removal of 90.5 % and 95 % for salinities of 5,000 and 2,000 mg/L, respectively.
