RJ Oil Inc has a patented system for removing hydrocarbons from water using a reversed cavitation technology. It dissolves gas into the stream and then evolves that gas as microscopic bubbles. These bubbles form on the surface of the impurities and stick to them forming a highly bouyant froth. The heavy solids, like sand, sink the the bottom and are carried out in the underflow. Low foot print, no chemicals, no heat and the only moving parts are the pumps.
