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

Green Car Congress

NOVEMBER 17, 2009

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. —Professor Andy Hong. The ozone in the bubble attacks certain pollutants because it is a strong oxidant.

A team from National Tsing Hua University, Taiwan, reports that a low-temperature solid oxide fuel cell (SOFC) emissions control system for lean-burn engines can simultaneously reduce the high concentrations of NO x and oxidize hydrocarbon (HC) emissions.
