The 3G UV Wastewater Disinfection Unit from Salcor Inc. is proven for residential, commercial and municipal uses. It is UL certified NEMA 6P “floodproof,” and NSF/Washington State Protocol pathogen six-month tested (with 20 different upstream treatment units). Rated to 9,000 gpd gravity flow makes it a reliable building block for larger water recovery/reuse systems. Installed 12-unit parallel/series arrays, assembled with readily available ABS pipe fittings, are disinfecting more than 100,000 gpd systems. Gravity flow is equalized without distribution boxes. Identical modular units increase plant reliability and reduce spare parts inventory, facilitating expansion. Each unit has a foul-resistant Teflon lamp covering, two-year lamp, easy installation and minimal annual maintenance. 760/731-0745.
