Inorganic membranes are promising to be used in separation in organic solvents due to their inherent stability under various types of organic solvents and the mechanical strength. In this article, organic solvent nanofiltration (OSN) and organic solvent reverse osmosis (OSRO) are reviewed from the viewpoints of membrane materials and their applications. The trend to develop high performance OSN and OSRO membranes are described. At present, very few OSRO membranes have been reported, while a variety of OSN ceramic membranes were reported and some of them are commercially available. In addition, the principle of energy–saving by OSN and OSRO is also discussed.
