The 3G UV Wastewater Disinfection Unit from Salcor is for residential, commercial and municipal uses, and is UL-certified NEMA 6P flood-proof and NSF/Washington State Protocol six-month-tested (with 21 upstream treatment systems). It inactivates pathogens, including deadly superbugs, according to the maker. Rated at 9,000 gpd gravity flow, it can be used as a building block for large water recovery/reuse systems. 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, easy installation, minimal annual maintenance, and energy usage of less than 30 watts of electric power. 760/731-0745.
