Full Description

As part of a preliminary design for a 2,000 mgd ultraviolet light (UV) disinfection facility for the City ofNew York, computer models have been used to predict the effectiveness of UV reactors at inactivatingpathogens with the goal of using the models to validate full-scale UV reactors.The New York City Department of Environmental Protection (DEP) has developed a protocol forvalidation of UV reactors through computer modeling (Valade 2003). The protocol includes two phasesof work. The initial phase is complete, and demonstrated that modeling could be used to predict theperformance of the Wedeco K3000 low pressure, high intensity (LPHI) reactor, validated at the DVGWTesting Facility (Rokjer 2002). The second phase of the protocol is to model one larger LPHI reactor, andextend the models to include several medium pressure (MP) reactors of differing capacities andconfigurations, all of which have been validated through biodosimetry. This paper presents the resultsof the modeling of two Trojan medium pressure reactors as part of a larger modeling program. Includes 16 references, tables, figures.
