WASHINGTON: A U.S. researcher has developed a proposal to develop a simple sewage disposal for the Third World, not just get rid of waste, but also work without using electricity or additional power to destroy germs.
Less than $ 100 and the day's work, a single-family underdeveloped country can build on this solid waste disposal system.
Marc Deshusses, Professor of Civil and Environmental Engineering at Duke Pratt School of Engineering, has plans to develop a plant digestion of the novel with the capture of methane gas that is produced during the decomposition of waste to produce enough heat to kill bacteria and viruses most frequently associated with human waste.
"People in countries that lack adequate sanitary facilities for its wastewater in desperate need of a disposal method that is inexpensive, easy to implement and maintain confidence," said Deshusses. "We believe that the proposed system could represent a breakthrough in protecting the environment and health in developing countries."
The system, designed by Deshusses, waste must be addressed to the Chamber, probably made of PVC pipes. When the closed chamber to create a oxygen-free, or anaerobic, environment, bacteria digest waste.
As a byproduct of digestion, methane gas is produced. "The system works like a septic tank used in many rural communities," said Deshusses.
But on the other hand, the methane released into the environment, a new approach for capturing and burning to create enough heat to kill pathogens in the liquid.
