Abstract
Desalination of seawater is a promising response to solve the lack of drinkable water. The separation of cations and anions is carried out by inserting a desalination cell in the middle of a novel design of Photo Electro Catalytic Desalination Cell (PEDC). Different parameters were evaluated and optimized for increasing the capability of system to desalt hyper saline water. Ultraviolet illumination (UV) is used as the driving force, exciting coated titanium nanotubes on the anode electrode, producing electron/hole pairs that degrade organic matters. Methylene blue degradation by UV irradiation is undertaken, owning a high salt concentration level, and desalinated to produce electrical current. Performance of PEDCs are investigated by salt content, pH, and ion exchange resin. The results indicates that higher Total Disolved Solid (TDS) removal occurs in acidic environments in anode chamber while the maximum produced electrical current occurs in alkaline environments in cathode chamber. Also, the higher amount of salt content in the middle chamber results in the high TDS removal until the amount of Electrical Conductivity in the middle chamber is 190 mS/cm. The TDS removal rate with and without using resins in the middle of the desalination cell after 10 days is 70.69% and 51.37%, respectively.
