Outline of Final Research Achievements |
We were able to successfully evaluate norovirus removal performance as particles during membrane filtration processes by using recombinant norovirus virus-like particles and the immuno-PCR method developed in the present study. In addition, a novel aluminum-based coagulant for effective virus removal was also successfully developed in the present study. A combination of coagulation pretreatment with the novel coagulant and microfiltration can provide effective removal of waterborne viruses including adenovirus and norovirus (more than 4 log) over a broader pH range than is possible with commercially available aluminum-based coagulant.
