Capacitive deionization (CDI) is one of attractive environmentally-friendly desalination processes. Since the applied potential is limited to a low region where electrolysis does not occur, the energy consumption during the operation of the process is also markedly reduced compared with the conventional desalination processes. However, CDI has the disadvantages of low ion selectivity and removal efficiency. In order to overcome the limitation of CDI, recently, membrane capacitive deionization (MCDI) process employing ion-exchange membranes (IEMs) has been proposed. In this work, we have developed a pore-filled IEMs (PFIEMs) for the applications to cost and energy efficient CDI processes. The membrane properties have been systematically investigated and also optimized for the successful application to MCDI process.
