Advanced Field and Laboratory Testing for a Sustainable Solar Sanitation System
Georgia Institute of Technology, 2008 - $34,333
The Georgia Tech Research Institute in partnership with the Emory University Center for Global Safe Water have designed, built and tested an innovative solar sanitation system for use in developing countries. Field prototypes of the systems have been constructed in rural areas in Bolivia with a local foundation partner. This system heats waste to temperatures in excess of 50 degrees Celsius (140 F), which destroys disease causing micro-organisms and bacteria. Addition of lime or ash increases pH to promote microbial inactivation. The waste is rendered harmless for use as fertilizer within weeks.
The objectives of this research are to
- conduct basic engineering and clinical research to further evaluate the field performance of initial prototype systems (temperature, pH and heating times needed for microbial inactivation)
- construct and field test advanced prototypes in Bolivia
- establish micro-financing and NGO partners for rapid and scalable use of the technology.
