Disinfection of Water with a UV-Catalyzed TiO2 Reactor

Photocatalysis, or ‘light-powered reaction’, is of growing interest in the water treatment. It is gaining attention due to its simplicity and efficiency in tackling many persistent contaminants that are harder to remove by conventional means. Researchers of this study will investigate the ability of UV-catalyzed titanium-dioxide pellets to oxidize and break down organics, such as pesticides and pharmaceutical compounds, which are ubiquitous in the environment. The results will guide researchers toward designing a lightweight, portable reactor for many areas in the developing world where the lack of sanitation and proper water treatment pose significant challenges in accessing safe drinking water.
