Ultraviolet disinfection system. Severn Trent Services’ UltraDynamics® 8102-HO-200 ultraviolet (UV) disinfection system has received validation test certification that conforms to the protocols prescribed by the US Environmental Protection Agency’s Ultraviolet Disinfection Guidance Manual (UVDGM). The UVDGM provides technical guidance on the application of UV light for the disinfection of drinking water by public water systems. The 8102-HO-200 UV system provides a UV dose of 30,000–40,000 micro-watt seconds per square centimeter at a wavelength of 254nm UV energy for the deactivation of microorganisms. After validation testing, the 0.8 mgd 8102-HO-200 UV system was installed at the Leslie Water Treatment Plant in North East, Maryland. It is expected to be fully operational later this year. The test plan for the validation was written by HydroQual Inc. which also conducted all testing and prepared the final validation report
