A Review on Preparation and Performance of Resistant Membranes for Application in Organic Solvent Nanofiltration

Over the past two decades, organic solvent nanofiltration (OSN) has been considered by a lot of researchers. This kind of membrane process can be a good candidate to replace thermal separation processes due to its advantages including; low energy consumption and reduction of solvent waste. Despite of these advantages, in the field of organic solvent separation, researches are limited to the laboratory and pilot scales and at industrial scale have not been developed except for few cases. Indeed, reluctance of industries to implement new technologies, hardness of large scale module construction for ceramic membranes and low stability of polymeric membranes are the most important parameters which prevent expansion of this process. This work review all kind of prepared polymeric, inorganic and mixed matrix membranes and their modification procedure for organic solvent nanofiltration. Additionally, the performance and chemical stability of prepared membranes has been investigated through solvent separation process.
