| Outline of Final Research Achievements |
The purpose of this project is to understand the disinfection effect of Norovirus using UV as the reclamation treatment technique. From the obtained study results, the infection risk of Norovirus by UV disinfection was examined in the various application of reclaimed water such as agricultural water use, recreational enhancement, and landscape water use.
When the UV disinfection to the treated sewage effluent of different water quality conducted, it was clarified that the disinfection effect of Norovirus differed by the water quality. From the result of the risk assessment in the reclaimed water which created UV disinfection, it turned out that the infection risk of Norovirus decreased from about 1/10 to 1/30, as compared with the case of using the treated sewage effluent directly.
