AquaPak
Solar Water Pasteurizer
Pasteurization Technology was invented by Louis Pasteur in 1867, but to date efforts to develop a small, extremely low cost, easy-to-use solar pasteurizer have failed to yield a viable solution for mass distribution. The AquaPak represents a significant breakthrough in this technology.
Made from low cost polyethylene plastic (also used in food preparation boiling bags) with UV inhibitors added, and air-filled bubble pak sheeting (originally developed for the packing industry), the AquaPak can heat water to temperatures beyond 70 degrees Celsius, a temperature that will kill all waterborne pathogens (bacteria, viruses, parasites) using only sunlight. By maintaining this temperature for specified time periods, the AquaPak kills a variety of pathogens present in contaminated drinking water. The edges of the plastic layers are bonded using medical sealing technology developed for use in blood and IV bags.
In tests conducted by BioVir Laboratories, San Francisco, CA, on virus contaminated water and by Environmental Engineering Laboratories, San Diego, CA, on bacterial pathogens, the AquaPak eradicated over 99.99% of the pathogens present.
NEW!
The AquaPak employs a reusable sealed glass tube indicator called a WAPI. it is filled with a Orange colored wax in a sealed glass cylinder which fits into the cap enclosure at one end that melts when the water is heated to the required temperature (67 degrees celcius), indicating the start of the pasteurization process.
