World's first microbe-powered, self-sustaining wastewater treatment system

Researchers from Washington State University have developed a unique method to use microbes buried in pond sediment for waste cleanup in rural areas.

The newly invented Microbial fuel cells use biological reactions from microbes in water to create electricity. The fuel cell does the work of an aerator and uses only the power of microbes in the sewage lagoons to generate electricity. In the lab the microbes were able to successfully power aerators for more than a year. The researchers hope to test a full-scale plant shortly for eventual commercialization.

The researchers claim that the technology could be used in underdeveloped countries to clean polluted water effectively at a cheap rate.


Details of the research appears in the latest issue of journal “Journal of Power Sources
