Research Topics, Overview of the research
Research Topics
Development of a method for selective determination of oxidising agents in the presence of a wide variety of coexisting substances such as sewage.
Development of ozone treatment control methods that follow fluctuations in influent water quality.Overview of the research
My research focuses on chemical water quality engineering, in particular on water purification with ozone, for all types of water, including drinking water, sewage and seawater. Ozone can purify water more powerfully than chlorine, which is widely used, while producing fewer undesirable substances (by-products), and is a treatment method that is expected to spread further in Japan. I am conducting both basic research, such as the development of water quality analysis methods, and applied research, such as the development of control methods in actual treatment plants.
