Lessons learned from deployment of UV advanced oxidation processes in the US
A practical framework for adopting UV-AOP in potable reuse — covering water quality, oxidant choice, and de-risking design with demonstration skids.
Overview
As water scarcity and aging infrastructure push utilities toward potable reuse, advanced oxidation has become essential for meeting strict disinfection and contaminant-removal standards. UV advanced oxidation (UV-AOP) stands out for its low cost of ownership and its ability to be tuned across treatment goals, but adopting it raises practical questions about water quality, oxidant choice, and design confidence.
Xylem and Water Online co-hosted this webinar, which introduces UV-AOP for advanced treatment and potable reuse, drawing on real-world installations using both hydrogen peroxide and free chlorine. You’ll learn where UV-AOP is the best fit, where alternatives like ozonation may perform better, and how to handle common challenges such as influent water quality and UVT monitoring. The session also previews a new approach to de-risking design: purpose-built demonstration skids that let utilities see full-scale performance before committing.
Viewers will leave with a practical framework for bringing UV-AOP into their own reuse programs.
