Electrodialysis Can Provide Cost Effective Treatment of Salty Well Water

A newly published study reveals how electrodialysis can provide cost-effective treatment of salty water from oil and gas wells. The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that’s much […]
