New tech from MIT aims to clean the water used in fracking so much that you’d happily drink it, even though it was once filled with chemicals.
One solution for dealing with the produced water: purify it really, really well.
A new water distillation process developed by researchers from MIT and King Fahd University of Petroleum and Minerals in Saudi Arabia vaporizes water under the boiling point when it comes into contact with a carrier gas. The resulting moist air bubbles pass through even cooler water and the vapor condenses.
MIT’s technology works best in a smaller size--producing 1,200 to 2,400 liters of water a day, or the amount of water needed for a rural village. And unlike other desalination systems, saltiness doesn’t affect MIT’s technology, making it ideal for producing water from fracking.
