Membrane symposium is one of the most important events of Japanese Membrane Society. It was held in Kyoto for a long time. Since I lived in Kyoto, I have a deep attachment to this Membrane symposium. My first attendance in this symposium is in 1994. After that, I attended in this symposium every year except for my 1 year staying in USA. Here, I overview my research activities based on the topics presented in Membrane symposium. The research topics that I did are Gas separation membrane, Porous membrane preparation by phase separation, Membrane fouling reduction, Membrane with channel material, Forward osmosis (FO) process and Organic solvent reverse osmosis (OSRO).
