Why UV-AOP Is Becoming A Cornerstone For Potable Reuse

As potable reuse becomes more common, UV advanced oxidation processes (UV-AOP) are gaining attention as more than simply a final-stage disinfection technology. By combining ultraviolet light with an oxidant such as hydrogen peroxide, UV-AOP generates free radicals capable of breaking down difficult-to-remove compounds that can pass through physical treatment processes such as granular activated carbon and microfiltration. For utilities evaluating UV-AOP, however, laboratory data and generalized case studies may not adequately account for site-specific water chemistry. Demonstration skids equipped with validated UV reactors and real-time instrumentation provide a way to evaluate performance under actual flow conditions and compare oxidants before committing to full-scale infrastructure. Real-world validation can help utilities and engineers better understand influent characteristics and reduce design uncertainty as potable reuse projects move forward.
