About the challenge
[edit | edit source]To use simple accessible technology to purify water The Solar Powered CleanPhoton creates heats and captures natural UV light to purify water
Description
[edit | edit source]It is well known that ultraviolet (UV) light has a disinfectant effect. Using a special ETFE film with high UV-transmission, it is possible to create very efficient and simple water disinfection systems. Sunvention has developed such a system, combining the effect of natural UV on water with solar heating of the water to over 50 degrees Celsius, effectively killing bacteria (including coliform bacteria) and viruses. The CleanPhoton is decentral, portable and modular. Single units can be transported as easily as a suitcase. The smallest module can disinfect six liters of water in two hours.
Units can be combined to create installations with capacity up to several thousand liters of water per day. Applications Production of drinking water from waste water / biologically contaminated water sources, with no need for electrical or mechanical energy. Can be used in aftermath of catastrophes Technical Details Daily water disinfection capability: 30 liters/day to several thousand liters/day Simple adjustment of orientation according to season Water temperature: over 50 degrees Celsius Estimated Working Lifetime: over 20 years
