The Role of UV Disinfection in Meeting U.S. Regulatory Requirements at an Existing Ozone Facility

摘要

The Incline Village General Improvement District owns and operates the Burnt Cedar Water Disinfection Plant located on the north shore of Lake Tahoe in Nevada. The plant currently produces 32.2 MLD of drinking water from an unfiltered supply with ozone followed by free chlorine residual disinfection. The facility now requires improvements and modifications to continue reliable operation, as well as additional treatment to comply with the EPA's Long Term 2 Enhanced Surface Water Treatment Rule. An alternative consisting of the continued use of ozone and the implementation of UV disinfection is under construction as the preferred treatment approach.
