A COMPLETELY PASSIVE CONTINUOUS FLOW SOLAR WATER PURIFICATION SYSTEM

Water-borne pathogens in developing countries cause several billion cases of disease and up to 10 million deaths each year, at least half of which are children. Solar water pasteurization is a potentially cost-effective, robust and reliable solution to these problems. A completely passively controlled solar water pasteuriza- tion system with a total collector area of 0.45 m2 has been constructed. The system most recently tested produced 337 litres per m2 of collector area of treated water on a sunny day. We developed our completely passive density-driven solar water pasteurization system over a five year span so that it now achieves reliable control for all possible variations in solar conditions. We have also substantially increased its daily pure water production efficiency over the same period. We will discuss the performance of our water purification system and provide an analyses that demonstrates that the system insures safe purified water production at all times.
