The International symposium on water and wastewater treatment technologies was held at Room 191, C Cluster, Kyodai-Katsura Campus on February 21st, 2012. Three prominent professors were invited form Japan, China and Korea. The purposes of the symposium are to introduce to the water and wastewater treatment technologies applied in each country and to the current situation of water environment of each country. We aimed at promoting cooperative research activities and at acquiring new research projects among three countries by sharing the information.


In the symposium, Dr. Hiroaki TANAKA, Professor of Kyoto University, talked about “Current situation of PPCPs pollution of Yodo river and countermeasures” as the first speaker. Pharmaceuticals, and Personal Care Products (PPCPs) are attracting more and more attention because of their properties, that is, their effects on human beings and aquatic environment are specific at the low concentration. The presentation included the pollution situation of water environment by PPCPs, the occurrence and fate of PPCPs in wastewater treatment plants, which is one of the point sources to the water environment, and treatment technologies for PPCPs decomposition by oxidation processes.
Dr. Hongying HU, Professor of Tsinghua University, talked about “Water safety evaluation and control for wastewater reclamation and reuse”. The main subject of the presentation was the wastewater reuse, and the topics included the wastewater reclamation and reuse in China, the challenges for risk management of reclaimed water, the control of microorganism-related risks, the control of dissolved organic matters and the future works. In the conclusion, some issues on wastewater reclamation and reuse were pointed out.
Dr. Hang-Sik SHIN, Professor of Korean Advanced Institute of Science and Technology, talked about “Advanced wastewater treatment in Korea”. He introduced to the environmental problems in Korea and four major water projects including Saemangeum reclamation project, restoration of covered streams in urban area, eco-industrial park and four major river restoration projects. He also explained about strategic research areas. They consisted of efficiency enhancement, phosphorus removal and recovery and wastewater reuse.
Not only staffs and students of Kyoto University but also a lot of people from other universities, institutes, private companies attended the symposium. We were able to know the latest academic knowledge and the current researches, and to share the information on the situation of water environment in each country and countermeasures carrying out up to now and perspective of each country.
