✦ Synopsis

Several projects concerning membrane developments and applications supported by various Japanese Ministries will be explained. Interesting membranes, which have been developed in these projects are, pervaporation membranes for alcohol separation, gas separation membranes for hydrogen separation and ultrafiltration membranes for high temperature sterilization.

Membranes applied to various biotechnologies are also explained. One example is in the alcohol fermentation process, where UF is used for recovery of enzymes, RO for concentration of sugar and pervaporation process for recovery of alcohol from fermentation broth. The other example is in the biological effluent treatment process, where UF membranes will be used instead of sedimentation.

Other interesting applications of UF, and new membranes made of porous ceramics and glass will be explained. Finally recent results of our works, including natures of dynamically formed membranes, those of charged ultrafiltration membranes and membrane distillation process, will be reported.
