ABSTRACT

UV disinfection is increasingly the process of choice for recycled water applications. The 2003 NWRI UV guidelines provide a rigorous framework for testing full-scale systems to demonstrate performance based on pilot data. This presentation will discuss the UV scale-up validation process performed at the El Dorado Irrigation District Deer Creek Plant in 2006. The validation has been accepted by DHS for full design capacity of the UV system. The information presented will provide insight into the most recent developments in implementation of UV disinfection for recycled water, which should be valuable to those considering, implementing, and navigating the approval process for UV disinfection for recycled water.
