| Outline of Final Research Achievements |
Recombinant norovirus VLP and some waterborne pathogenic viruses (poliovirus and adenovirus) were artificially added to a wide variety of raw water for drinking water that were obtained from actual drinking water treatment plants in Japan, and virus removal during conventional coagulation-sedimentation treatment was investigated. The removals of the waterborne pathogenic viruses were found to be 0-2.5 logs, which were lower than that of bacteriophage MS2 but higher than that of bacteriophage phiX174. The observations suggest that not MS2 but phiX174 could be a conservative surrogate of the waterborne pathogenic viruses. However, further study is still required for the suggestion by using a wide variety of treatment conditions.
