Welcome to the website of the Water Treatment (Prof. Takahiro Fujioka's) Lab in the Water & Environmental Science Program, Graduate School of Engineering, Nagasaki University, Japan. The Water Treatment Lab focuses on the development of membrane-based water treatment technologies and analytical techniques to produce high-quality and reliable recycled water for Potable Water Reuse. In addition, we are also developing low-capital/operating cost water treatment technologies for developing countries (Our Water Environment Research Activities).
