Overview of the Research Project

Reduce the startup and operational costs of advanced water purification by 80%!
River water is the main source of drinking water in Southeast Asia, including Vietnam, but increasing pollution means regular treatment methods cannot guarantee its safety. The high startup costs and operational costs of advanced water treatment methods capable of removing these pollutants prevent their widespread use in developing countries. In this project, we are developing an advanced water treatment method that is cheap, uses very little energy, and uses locally procurable components, as well as water quality measurement technology to enable online water safety monitoring.

Sustainable water supply for residents and industry
This project will expand the use of advanced water treatment in waterusing facilities (purification plants, commercial buildings, and industries using industrial water) in developing countries, benefiting society by providing a sustainable supply of safe, cheap water to residents and industry. It will also help promote production by Japanese companies and organizations in those regions by supplying them with low-cost thoroughly treated water.
