Abstract
Water contaminated with oil is separated within a closed container into an oil layer and a water layer containing a residue of oil, because of the difference in the specific gravities of water and oil. A suction pump sucks the separated oil from the container to reduce the pressure of the liquid in the container, thereby lowering the concentration of oil residue in the separated water.
