Los Angeles-based OriginOil, Inc. is marketing a technology that uses electrical impulses instead of chemicals to clean water used in hydraulic fracturing. The product originally was designed to separate algae from water so that it can be used to make biofuel. In a fracking application, the impulses first neutralize the repulsive electrical charge of suspended particles and oil droplets, allowing them to be separated from the water. A second series of impulses lifts the lighter particles to the surface and makes the heavier particles drop to the bottom. The particles are then raked off and processed. The United States Department of Energy’s Idaho National Labs (INL) recently ordered a test scale unit of the technology for use in a demonstration project. Read more...
