AquaPak Solar Water Pasteurizer
Solar water pasteurization is the most economical and safe way to eliminate pathogens (bacteria, viruses, parasites, etc.) like cholera and salmonella from fresh water sources. If the temperature and time defined on the pasteurization chart shown below are achieved, the system is almost "goof proof" (Dr. Feachem, et. al. 1983).
Pasteurization is the process of choice for millions of gallons of milk, beer, wine, honey and many other beverages in the industrialized world.
The key to solar water pasteurization is to ensure that the water gets hot enough for long enough time. The AquaPak is a polyethylene solar water pasteurizer designed to achieve water temperature of 65 degrees Celsius which will reduce all pathogens by 99.999%.
