💡 EPA / NSF 55 Class A UV Disinfection (40 mJ/cm² Fluence @ 254 nm, UVT %)

UV Water Disinfection Fluence Calculator

Size closed-vessel and open-channel ultraviolet (UV) disinfection reactors under US EPA UV Disinfection Guidance Manual (UVDGM) & NSF 55 Class A: calculate delivered UV fluence dose (40 mJ/cm² at 254 nm germicidal wavelength accounting for water Ultraviolet Transmittance UVT 75-95%), low-pressure high-output (LPHO) lamp arrays, and UV margins.
