Report 047


Reuse of treated wastewater is very important issue for both developed and developing countries. Increasing demand for alternative water resources and increasingly stringent water quality discharge requirements are the two primary driving forces for using treated wastewater, to meet some of society's water demands. When an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established. Several problems relevant to pathogen in water reuse are faced by developing countries. The improvement of conventional technologies and application of new technologies will be, therefore, critical for sustainable operation even though no health issues have been reported from reuse of treated wastewater. The purpose of this symposium is to discuss and share current experimental results on pathogen, and new findings and ideas on the control of pathogens in water.


In the symposium, Ilho Kim, GCOE researcher of Kyoto University introduced the objective of the symposium on the health-related microorganisms in water. In addition, Hiroaki Tanaka, the leader of GCOE Health Risk Management group gave a presentation on the introduction of GCOE program and the activities in overseas bases. About 50 participants including faculties and students of Kyoto University and local government official attended the symposium, and actively discussed the current issues related to pathogen in water. Including the presentation on the disinfection technology of pathogen by UV given by Professor Naoyuki Kamiko of Ritsumeikan University, recent studies on the contamination of water quality with antibiotics- resistant microorganism, disinfection effectiveness of ozone for virus and the removal of E.coli by advanced oxidation processes such as UV/H2O2 process were introduced, resulting in enhanced comprehension about current problems of pathogen occurrence, regulation and control method.
A banquet closed the symposium offering Kyoto University professors and students a chance to strengthen the ties with master and Ph.D students from Ritsumeikan and Ryukoku University. Poster presentation was also done during the banquet to have a chance to introduce recent studies which have been performed at each University. More friendship among the participants and better understandings of each study were promoted through the banquet and poster presentation.
