Abstract: A skimming system for removing a floating layer from a water surface. The skimming system includes at least one guide element that is movable relative to the floating layer, which guide element includes at least one unit that catches the floating layer. The at least one removal unit includes at least one collecting container that is detachably attached to the guide element. The collecting container is furthermore vertically adjustable, so that it is not only easy to detach and exchange the collecting container but that it is moreover possible to position the floating layer removal means at a desired depth in or below the floating layer. In this way an optimum removal of the floating layer can be realized. The inlet of the collecting container is present at a location where the extent to which water is mixed with the floating layer is minimal.

Abstract: A separating device for two liquids of different density, in particular for separating an oil layer floating on a liquid surface by means of an over flow edge on a weir, said edge being positioned in the area of the boundary layer of the two liquids. The separating wall provided with the over flow edge has an convex-concave shape in a vertical direction and seals against the inside of the convex weir whereby an improved sealing with less leakage is obtained.The separating wall is hollow and can be accurately positioned vertically by remote control by means of supplying more or less air under pressure to the inside of the separating wall so that the buoyancy thereof can be varied according to the thickness of the oil layer. For obtaining a quick response to wave action a float is positioned in front of the separating wall and controls the vertical position thereof starting from the adjusted nominal position reached by the remote control by air pressure.
