The 3G UV Wastewater Disinfection Unit from Salcor is designed for residential, commercial and municipal uses, and is UL-certified NEMA 6P Floodproof and NSF/Washington State Protocol six-month tested (with 21 upstream treatment systems). It inactivates pathogens, including superbugs. Rated at 9,000 gpd gravity flow, it is a reliable building block for large water recovery/reuse systems, according to the maker. When installed in 12-unit parallel/series arrays with ABS pipe fittings, systems are disinfecting over 100,000 gpd. Gravity flow equalizes without distribution boxes. Identical modular units increase plant reliability and reduce the need for spare parts, facilitating plant expansion. Each unit has a foul-resistant Teflon lamp covering, two-year long-life lamp, allows for quick installation, requires minimal annual maintenance and uses less than 30 watts of energy. 760/731-0745.
