Research Topics

　　Water holds intrinsic value in both quality and quantity, serving as an indispensable resource for healthy living and sustainable societal activities. To maximize its value sustainably, research focuses on various topics, such as water environment surveys, water treatment technologies, and water supply systems. For example, research on UV-based water treatment ranges from fundamental experiments to large-scale applications, with results achieving technological implementation and earning international recognition. Efforts also address water-related challenges in developing and remote areas through continuous fieldwork on water quality and usage. In addition, decentralized small-scale water systems are being explored as potential engineering solutions to urgent societal challenges, such as population decline, aging populations, and deteriorating infrastructure.
