Ion-Exchange Membranes
Description
Ion-exchange membranes have the function of desalination and concentration of saline water. Further the membranes separate ionic species dissolved in a solution. Based on the fundamental studies, application of ion-exchange membranes is extending widely in many fields. The largest application is the demineralization of salt solutions. The other applications are desalination and reuse of sewage or industrial waste, refining of amino acid solutions, desalination of milk and sugar liquor, recovery of the useful components from industrial waste, production of inorganic chemicals, and so forth. Electrodialysis is fundamental technology based on the ion-exchange membrane. However, ion-exchange membranes are now applied to other fields such as electrodialysis reversal, bipolar membrane electrodialysis, electrodeionization, electrolysis, diffusion dialysis, fuel cell, redox flow battery, Donnan dialysis, reverse electrodialysis, and membrane capacitive deionization. Applications of ion-exchange membranes in the above fields are expected to be discussed from fundamental and practical view points in this special issue. Potential topics include, but are not limited to:
- Membrane preparation
- Membrane characteristics measurement
- Membrane applications
- Mass transfer and energy consumption in the process
- Trouble prevention
- Environmental problem
- Process design and operation
- Cost evaluation
