Abstract
In order to separate oil from an oil-water mixture and in order to reduce the level of pollution in the water which is recovered, to prevent environmental pollution, the mixture is conducted over a plurality of inclined planes (18, 20, 22, 24) which are arranged at an acute angle relative to each other, in a housing 12, provided with a fleece 30 which repels oil. Thereby, the water penetrates through the fleece and is fed at the lowest point of one of those planes to a collection device (34, 36, 38, 40, 42) whereas the oil is collected from above the fleece at the lowest point of the bottom most plane 24.
