GE says it has developed technology that can help resolve one of fracking's major environmental problems, the waste water generated in the process of tapping shale, reports MIT Technology Review.
Technology Review: "... The new technology would make it unnecessary to dilute the wastewater, or transport it for treatment or disposal. It is based on a desalination technology known as membrane distillation, which combines heat and decreased pressure to vaporize water using membranes to separate pure water vapor from salt water.
" ... Based on pilot-scale tests of a machine that can process about 2,500 gallons of water per day, GE researchers say they are on track to cut the costs of treating salty fracking wastewater in half. The system needs to be scaled up for commercial use, but a full-sized system could treat about 40,000 gallons per day."
