A COMPARISON OF UV DISINFECTION FOR DRINKING WATER, WASTEWATER, AND RECLAIMED WASTEWATER
Abstract:The role of UV disinfection in the U.S. is changing. UV dose requirements are changing due to the discovery of UV-resistant virus and UV-sensitive protozoan cysts/oocysts. UV is being introduced to municipal drinking water applications with strict requirements for dose delivery monitoring and validation. Reclaimed wastewater UV applications after membrane filtration reflect drinking water applications more than wastewater applications. This paper discusses differences between drinking water, wastewater, and reclaimed wastewater applications of UV disinfection, with an emphasis on water quality impacts, UV dose requirements, compliance monitoring, and validation. Appreciating these differences will assist utilities in better understanding their UV needs.
