Abstract

Electrodialysis (ED) is an efficient process that desalinates brackish and saline water under the influence of the electrical field. The ions that present inside a solution moves through ion exchange membranes to the adjacent compartments called concentrate compartment. The main purpose of the ED process is to desalinate brackish water; besides this, a valuable energy carrier gas, hydrogen is generated at the cathode side of the ED cell in this study. However, due to the internal recirculation of the electrolyte solution from anode to cathode compartment, hydrogen gas reacts with oxygen gas and reforms water. In this study, the potential of hydrogen gas generation in an ED system while treating saline/brackish water, is experimentally investigated. The ion removal efficiencies are 68% and 67% for combined and separated processes, respectively. The hydrogen production rates of the ED system are 2.42 and 3.28 mL/h.cm2 for combined and separated processes, respectively.
