N2 - The design, simulation, and testing of a novel portable pasteurization system suitable for the daily needs of four individuals are presented. This is the first self-powered, large-scale portable system developed to kill waterbome pathogens that contaminate current water supplies worldwide. The major components of the system consist of available technology: two evacuated solar collectors, a heat exchanger, two holding tanks, and a thermostatic valve. Flow of contaminated water through these components is permitted only when the temperature specified by the thermostatic valve is reached. Simulation of system performance is obtained via a lumped capacitance, time-dependent analysis with a limited number of input parameters. A prototype pasteurizer was designed and constructed, and proof-of-concept experiments were conducted in Minnesota in May 1998. The system was able to deliver nearly the predicted quantity of pasteurized water, approximately 70 liter/day.
