Topics covered include: ultraviolet (UV) reactor validation issues, approaches, costs, and pros/cons; off-site validation at manufacturer facility (case study of Seattle Public Utilities' CedarDesign-Build-Operate Project); off-site validation at test center (case study of Poughkeepsie's (NY) WaterTreatment Facility); on-site validation (case studies of City of Henderson, Nevada and Clayton County Water Authority, Georgia); and a "hybrid" approach (case study of City of Winnipeg, Manitoba, Canada).
