Capacitive deionization (CDI) is one of the most interesting technologies for water treatment industry. Using the electrical potential differences between two electrodes, salt ions in brackish water can be removed with relatively low energy.

In membrane-CDI (MCDI) system, a salt solution, which passes between cation and anion exchange membrane (IEM), can be more easily desalinated as well as spending lower energy. In this field, membrane materials have been intensively investigated as an important issue for process efficiency. A number of materials have been considered for industrial application so far. The main issue of ionic transport membrane for CDI is anti-fouling on the electrode and high ionic conductivity as well as keeping low cost.

Recently, we has been developed flow electrode-CDI (FCDI) for energy saving and easy-applying technology. [1] Flow electrode can present continuous system during adsorption/desorption mechanism for fluidic carbon electrode, resulting in practical technology for industrial application. Membranes for FCDI will be developed and modified for flow-electrode. Analytical study for electrical double layer between flow-electrode and IEM will also be studied.

The position will be open for the one who majored in ionic-exchange membrane for water desalination, and is interested in membranes for flow-electrode capacitive deionization (FCDI) technology.
