OFF SPEC PERFORMANCE AND PUBLIC HEALTH PROTECTION WITH UV DISINFECTION
Abstract:Off spec performance calculated by volume or time can provide significant under or over estimations of the public health benefits of UV disinfection system performance. As an alternate to off spec calculations, a UV System log credit, calculated as an integration of UV system performance across reactors and as a function of time, is proposed. Benefits of the approach are simplified yet more meaningful reporting of UV system performance, quantification of the health impacts of off-spec performance, and justification for operating strategies that use over dosing to offset minor off spec performance events.
