| Outline of Final Research Achievements |
In the present study, removal of waterborne human-infective viruses (WHIVs) during drinking water treatment processes were estimated by a combination of lab-scale batch experiments and field-survey in an actual drinking water treatment plant. The lab-scale experiments revealed that pepper mild mottle virus (PMMoV) could be an indicator of 4 WHIVs (adenovirus, coxsackievirus, hepatitas hepatitis A virus, and murine norovirus) during coagulation-sedimentation-sand filtration (CSF) processes. The field-survey showed that 1.6-removal of PMMoV, on average, was achieved during the CSF in the actual treatment plant. Therefore, we concluded that 1.6-log removal could be also expected for the WHIVs in the CSF in the actual treatment plant.
