Pentagon-backed researchers have come up with a novel new way to purify water: Just add bacteria.
Scientists at Sam Houston State University (SHSU) have successfully designed portable, efficient, bacteria-based water treatment units. Two of the devices are on their way to Army bases in Afghanistan, and the research team is in talks with the Pentagon about sending a working prototype to help relief efforts in Haiti.
The systems, called “bio-reactors,” clean putrid water using the same bacteria you’d find in a handful of dirt. The bacteria filter the water, then eat up the sludge that’s a common byproduct of waste treatment. It’s all done in less than 24 hours, and from devices smaller than a standard shipping crate.
