| Outline of Final Research Achievements |
In this study, innovative forward osmosis membranes (FO membranes) were developed for the purpose of concentration with low energy consumption of wastewater and radioactive water pollution. FO enables spontaneous transport of water molecules through a selective membrane from a lower concentration solution to a higher concentration solution by an osmotic pressure gradient. Thus, FO membrane process is regarded as a low energy consumption process promising an emerging technology. Both water channel membrane with biomimetic property and hydrogel membrane with micro-phase separation were prepared as FO membrane and their performances were evaluated. In addition, FO membrane fouling was also investigated because this fouling reduction is crucial to commercialize the FO membrane process.
