Solar disinfection of fluid

A device to measure photodisinfection treatment of water by ultraviolet radiation from the sun, comprising:

• a container for holding the water, the container being substantially transparent to the radiation, the container being further configured to enhance exposure of the water to the radiation by a geometric design that limits the cross-section of the water volume in a primary direction of incident radiation;
• an optical sensing component configured to estimate an intensity of radiation incident to a face of the optical sensing component and having wavelengths that correlate with the treatment, the optical sensing component being affixed to the container such that the face of the optical sensing component is oriented normal to a primary path of the radiation, the optical sensing component being disposed within the container so that the radiation incident upon the optical sensing component passes through the same material as the radiation incident upon the water;
• and
• a computing component that estimates treatment progress using optical sensor measurements over time, allows a user to initiate or terminate treatment process monitoring, and provides an indication of treatment progress.
