🧪 MAHC / EPA (Cryptosporidium 3-Log Inactivation, 60 mJ/cm² Medium-Pressure UV)

Secondary Pool Disinfection (UV) Calculator

Size secondary inline disinfection systems (Medium-Pressure polychromatic UV reactors and corona discharge Ozone generators) for public water parks and splash pads under the CDC Model Aquatic Health Code (MAHC): calculate UV dose (strictly ≥ 60 mJ/cm² for 3-log [99.9%] inactivation of chlorine-resistant Cryptosporidium oocysts and chloramine destruction), and aquatic safety margins.
