The Illumi-Jet UV Disinfection Unit from Jet Inc. is capable of reducing fecal coliform bacteria levels to well below the most stringent U.S. treatment standards, according to the manufacturer. It uses a germicidal lamp, which emits 95 percent of the ultraviolet energy at the wavelength of 254 nanometers. This wavelength is in the region of maximum germicidal effectiveness and is highly lethal to virus, bacteria, protozoa and mold. The disinfection chamber couples directly to any system’s 4-inch discharge pipe, and is permanently installed below grade. When fully inserted, the lamp housing is correctly positioned by an integrated keyway near the top of the disinfection chamber and creates a well-defined flow path, ensuring system effluent has the proper ultraviolet exposure time. Under standard operating conditions, fecal coliform reduction exceeds 99.9 percent. 800/321-6960;
