UV-chlorine advanced oxidation for potable water reuse: A review of the current state of the art and research needs

This paper reports conclusions from a recent study completed for the Water Research Foundation and the State of California to offer guidance on UV-chlorine advanced oxidation for potable water reuse. The fundamentals of UV -chlorine advanced oxidation are discussed, and lessons learned from some of the early adopters of this tech-nology are presented. Important highlights include the significant impact of ammonia and chloramines on UV -chlorine treatment, challenges associated with predicting UV-chlorine performance due to complex photo-chemistry, and an ongoing need to monitor potential byproducts and transformation products when employing any form of advanced oxidation for potable reuse.
