Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oil sands and oil shale. Heavy metals in soil.

The team, from the Desert Research Institute, University of Colorado Boulder and NOAA, and Stanford University, began by defining a consistent vocabulary, first by jettisoning the popular umbrella label of “fracking” applied to unconventional oil and natural gas development.

60% of ground-level ozone (O 3 ) precursors, 6% of fine particulate matter (PM 2.5 ), and 22% of greenhouse gases (GHGs) emitted. GREET models five groups of air pollutant emissions: NO x ; non-methane volatile organic compounds (VOCs); primary particulate matter less than 2.5 Associated tailpipe emissions alone account for 40?60%
