| Outline of Final Research Achievements |
Virus removal in real water treatment plants was studied from the indigenous viruses present in the water. In Bankok, Thailand, 11 raw water samples, 11 water samples after coagulation/sedimentation, 10 water samples after rapid sand filtration were collected. In Hiroshima prefecture, at 2 water purification plnats 32 samples in total were collected. The virus concentration was measured, among which PMMoVs were most frequently found. As a result, rapid sand filtration with coagulant showed higher removal capacity than slow sand filtration.
