Energy Efficient UV Upgrade at the Arrowhead Ranch Water Reclamation Facility

Ultraviolet (UV) disinfection has emerged as a viable alternative to traditional disinfection technologies. The City of Glendale has received an Energy Efficiency and Conservation Block Grant (EECBG) from the Department of Energy (DOE) to implement cost saving measures at the Arrowhead Ranch Water Reclamation Facility (ARWRF). This paper discusses the energy efficiency modifications made at the plant to improve the energy used by the UV disinfection system.
