Feasibility of Full-Scale Implementation of LED UV Disinfection

UV radiation has been used to disinfect drinking water and wastewater for decades. Conventional municipal UV disinfection systems rely on mercury vapor lamps that emit radiation at 254 nm. UV disinfection is highly effective in pathogen control, however environmental, economic, and applicability issues should be considered when using conventional UV and UV LED technologies.

The objective of this project is to perform a quantitative assessment of the feasibility of full-scale ultraviolet light emitting diode (UV LED) water disinfection reactors for drinking water and wastewater treatment applications. The analysis will consider disinfection performance, technological, economic, and environmental feasibility against new-site and Hg-replacement installation scenarios.
