Abstract: A system for solar disinfection of fluid. One most preferred version of the system includes: (a) A UVTC, made of a polyethylene laminate film with an approximately rectangular plan, providing: a. A first compartment. b. A second compartment for holding fluid, with a port to fill and dispense. (b) A Disinfection Monitor Module (“DMM”) located in the first compartment which: a. Includes at least one sensor to measure radiation intensity. b. Provides at least one user interface: c. Contains a wireless communication interface. d. Operates according to a process that ensures sufficient cumulative exposure of the contained fluid to solar UV to achieve adequate solar disinfection. Alternative embodiments may also include sensors to detect additional characteristics, such as transmittance, turbidity, “combined transmittance,” and/or temperature.

Abstract: A system for solar disinfection of fluid. One most preferred version of the system includes: (a) A UVTC, made of a polyethylene laminate film material with a “cut and weld” process, shaped generally like a pillow with an approximately rectangular plan, providing: a. A first compartment. b. A second compartment for holding fluid, with a port to fill and dispense, the second compartment proximate to the first compartment. (b) A Disinfection Monitor Module (“DMM”) located in the first compartment which: a. Includes at least one sensor to measure radiation (e.g. solar UV light) intensity. b. Provides at least one user interface including: i. “Start” and “stop” pushbuttons, switches or the like. ii. “Wait” and “Safe” visual indicators, such as LEDs. c. Contains a wireless communication interface. d. Operates according to a process that ensures sufficient cumulative exposure of the contained fluid to solar UV to achieve adequate solar disinfection.
