General Description of the Research Project

Seeking technologies for water recycling at a purification facility to meet the rapidly increasing demand for water
Water demand in Thailand is increasing rapidly due to industrialization, urbanization, and so on. However, water resource quantities are unstable, and there are problems with sanitation as well. For this reason, an effort is underway to purify and reuse water that has been used once, in order to secure an adequate quantity of water. The goal of this project is to construct three types of water purification facility suited to the tropical climate and local conditions in Thailand: energy conserving distributed facilities, solar-powered facilities, and facilities that treat water while at the same time producing bioenergy. Demonstration plants have already been set up at locations such as a university campus in Thailand, and development of water recycling technologies is underway.

Experiments and data collection are performed in the same environment as the site to aid in technical development
Water analysis equipment was set up in Thailand to establish a water reuse center as the central institution to drive R&D and the broader adoption of water reuse. In addition to testing and data gathering in Japan, work using test plants is progressing at a Thai university campus and other locations in order to develop new technologies. The test plants for recycling water within local areas are being installed in agricultural districts and at locations such as residential facilities to simultaneously acquire verification data and promote their use in the community.
