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.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Eventually, they’ll add equipment to spray tiny aerosol particles of calcium carbonate, the compound found in limestone, blackboard chalk, and Tums antacids.
