MF/UF技術の現状と今後の展望

抄録

In this paper, I mention that how wide MF/UF technologies are used in many industries all over the world, the rea-son why MF/UF technologies are used in various industrial field, and future vision of MF/UF technologies in orderto contribute more strongly to the human life and the earth environment. The main reasons why MF/UF technolo-gies are expanding in many applications are follows; (1) MF/UF process is energy–saving process compared withother separation process such as distillation process, (2) by using MF/UF process, proteins does not denature withheating because MF/UF process does not require phase conversion, (3) in several cases, MF/UF technology is actu-ally the only one way at this moment to remove impurities such as micro–particles in ultra–pure water in semiconduc-tor field, and (4) MF/UF process can keep better water quality than conventional sand filtration process in the drink-ing water production. As mentioned above, I believe MF/UF technologies are useful and necessary for the earth in21stcentury. In order to reply the expectations, we must develop MF/UF technologies from the viewpoint as follows;(1) progress of economical efficiency, (2) thinking about not only membrane element but also total separation sys-tem.
