Abstract
A method and apparatus for operating on skimmed oil/water picked up from a body of water to separate the oil from the water and discharge the oil-free water back into the body of water, first feeds the skimmed oil/water into a gravity settling tank wherein the oil tends to settle above the water, removing relatively oil-free water from the bottom of the tank and measuring its oil content with an oil concentration sensor, and either returning the oil/water flow to the settling tank for further processing if the measured concentration of oil exceeds predetermined limits or discharging the water back into the body of water if the oil concentration is measured to be less than the predetermined value.
