Skimming and separation device—central rotating flow

A skimming and separation device comprising

• an outer casing provided with constructions to directly or indirectly fasten all parts, defining a compartment,
• a floater configured to create a skimming function of the device, the floater being attached at its lower side to an essentially vertically arranged bellow allowing the floater to adapt flow into a substantially circum volume and allowing the floater to move from an upper position with essentially no flow into the compartment to a lower position allowing flow of water and debris for following the contours of the floater in a downward direction into the device,
• a power device with a propeller, wherein said power device is configured to be controlled by a control unit such that various kinds of flows and pressures may be generated to control the in-flow and outflow of the device, and
• a central tube arranged along a vertical center axis of the compartment and configured to receive said flow of water and debris, and at least one central rotation member being structured to generate a downward directed and central rotating flow of said water and debris within said central tube, and wherein said at least one central rotation member includes deflecting members provided within said vertical central tube.
