Household Solar Disinfection Under Real Turbidity: Bottle Geometry, the Reflector Gain, and the One-Day Storage Rule

SIMULATED, NOT MEASURED. Delivered UV-A dose is computed for household SODIS across turbidity and bottle age: at 20 NTU a new bottle delivers 82 Wh/m2 (below the 120 Wh/m2 virus target) and a stated 1.35x reflector restores 122 Wh/m2. A five-person household needs 9 bottles daily and storage is capped at one day after opening. Nothing was built or field-tested.

Abstract

SIMULATED, NOT MEASURED. Delivered UV-A dose is computed for household SODIS across turbidity and bottle age: at 20 NTU a new bottle delivers 82 Wh/m2 (below the 120 Wh/m2 virus target) and a stated 1.35x reflector restores 122 Wh/m2. A five-person household needs 9 bottles daily and storage is capped at one day after opening. Nothing was built or field-tested.
