IUVA Education Committee Launches Resource Center

The Education Committee has created the IUVA Education Resource Center, a broad-based archive and knowledge base. Each segment of the site will be curated by senior experts and professionals who guide the selection of materials, explain their significance and rate them for usefulness and completeness. The Education Resource Center will provide both those who need information and those who want to provide education and correct information about UV with a central, reliable place to go and contribute their expertise. While strict moderators will enforce community behavioral standards and forbid negativity, contributions from vendors, educators, engineers, consultants and regulators alike will be welcomed. The IUVA Education Resource Center will include a Curated Research Repository to promote the most up to date information and collaboration throughout the industry. For more information, visit

Students Win Awards at IUVA World Congress

Submitted by Ron Hoffman

Student award winner Tianyi Chen; Oliver Lawal from Aquisense presented the award.

The 2023 IUVA World Congress had tremendous participation from students from all over the world. There were 16 presentations by students on topics ranging from drinking water disinfection to innovations in LED technology to applications in advanced oxidation. The technical information presented was outstanding, and it often led to some lively debate and new opinions and ideas shared over coffees in the hallways after the sessions.

As is custom at these conferences, the biennial “Jim Bolton Student Presentation Award” was given to the best student presentations, as determined by a panel of judges representing different parts of the UV industry. The award honors the tremendous mentorship that Jim offered countless students in their UV research at academic institutions worldwide. This year, the winner of the award was Tianyi Chen, a PhD student at the University of Toronto exploring how breakpoint chlorination reactions following RO in water reuse systems could affect UV-chlorine AOP performance. Tied in second place were Priya Dharwadkar from Cranfield University, who reported on UV-LED chlorine AOP performance for pesticides, and Yu Zhong from the National University of Singapore, who spoke on UV-LED/chlor(am)ine treatment of micropollutants in reuse applications.

The quality of the student presentations confirms that the industry has an up-and-coming generation of outstanding contributors to UV innovation and technology.

2023 IUVA Beijing Symposium Held in September

The 2023 IUVA Beijing Symposium: Innovation and Practice was held in Beijing on September 15, 2023, together with the 9th National Symposium on Water Disinfection and Disinfection By-Product Control. The Symposium was hosted by the Research Center for Eco-Environmental Sciences, the Chinese Academy of Sciences and IUVA. This symposium focused on scientific forefront and development direction in the research field of disinfection and disinfection by-products, with a goal to share challenges and successful experiences in the practices of UV technology for water treatment, under the theme of “Challenges and Opportunities for UV Disinfection in the Post-Pandemic Era.”

At this Symposium, speakers from 22 institutions delivered 27 presentations, attracting over 200 attendees from both academia and industry. At the opening ceremony, the IUVA president Ted Mao delivered a welcoming speech. Throughout the symposium, the topics includes emerging light sources, dose determination methods, new mechanisms and engineering practices. All attendees and participants actively engaged in discussions, sharing their insights, experiences and perspectives on the research and application of UV disinfection technology. At the closing ceremony, Professor Zhimin Qiang, the chairman of 9th National Symposium on Water Disinfection and Disinfection By-Product Control, provided a comprehensive summary of the event.

This symposium successfully enhanced the communications between China and the world in both academia and industry regarding hot topics, such as COVID-19 pandemic control, air disinfection and surface disinfection. In addition, the symposium included a comprehensive introduction of IUVA, which will increase its influence in China and inspire more Chinese researchers to become part of the IUVA community. Overall, this was a successful symposium that is of great significance for the development and improvement of research and application of UV disinfection technologies.
