01 Description of Research

My research target is on safe, stable and sustainable water systems including treatment and supply, and water-related health issues such as microbial contamination of water and feasible disinfection technologies are of particular interest. UV disinfection has been the top priority field of study in my research career. Besides large-scale municipal water supplies, I am also interested in small-scale decentralized water treatment systems to be owned, operated and maintained by a community or each household, and several field-testing projects of such small systems have been conducted in remote areas with limited/no access to public water supplies. Moreover, water treatment systems for industrial and medical applications have been challenged in my research scope.

– Water supply systems
– Water treatment technologies
– Ultraviolet (UV) disinfection
– Application of UV-LED to water treatment
– Small-scale decentralized water treatment and supply systems
– Health-related microorganisms in water
