Abstract:

Following the widespread implementation of ultraviolet (UV) disinfection, many utilities have begun to consider the potential use of UV light at higher doses, together with upstream hydrogen peroxide feed, as an advanced oxidation process (AOP). The use of UV AOP following membrane filtration and reverse osmosis has become a typical approach for indirect potable reuse projects around the world. In addition, UV AOP has been evaluated on a handful of drinking water projects with high water quality goals, and for sources of supply that are affected by typical point-source and non-point source influences. With this early wave of UV AOP projects, UV AOP represents an emerging technology for water treatment and water reuse. Understanding project experience and lessons learned from these early projects is critical in taking UV AOP from an emerging technology to a robust, proven process ready for implementation. This manuscript summarizes key issues from three projects around the world moving forward with implementing UV AOP at full-scale from 6 to 50 mgd.
