Bacteria Could Be the Solution To Clean Drinking Water

Chemicals such as percholorates found in our drinking water are known to inhibit the function of the thyroid gland and harm embryotic development. But removing such bad chemicals is not an easy process, and researchers are exploring ways to make this process possible on a large scale. At a recent American Chemical Society conference, Bruce Rittman of the University of Arizona-Tempe told attendees he has turned to bacteria as a possible solution to clean drinking water. His system uses bacteria grown on membranes, which is then wrapped into spaghetti-like strands that feeds on hydrogen gas and perchlorate to produce water and chloride. These strands are then filled with hydrogen and bundled into cylinders through which the contaminated water flows. The use of bacteria to clean drinking water is still an emerging technology, but it does provide an interesting solution to improving drinking water.
