Current status and prospects of water treatment membrane technologies for solving water problems

Abstract

Water is essential to our lives and is an extremely familiar presence to us. However, it has recently attracted significant attention worldwide. This is because the rise in population and economic development at a worldwide level have led to the growing demand for water and increase water pollution. In this paper, we report water treatment membrane technologies that contribute to solving global water problems, and most importantly the current state of water recycling technologies and the development of Japanese businesses and technologies in the world. We also report projects that appear to be particularly important,“the Mega-ton Water System” and “Water Plaza”, and their technical development issues.
