Abstract

A skimming and separation device comprising an outer casing (1) provided with constructions to directly or indirectly fasten all parts, defining a compartment (2), and a floater (3) configured to create the skimming function of the device, the floater is attached at its lower side to an essentially vertically arranged bellow (4) allowing the floater to adapt flow into a substantially circus volume and allowing the floater to move from an upper position with essentially no flow into the compartment (2) to a lower position allowing flow of water and debris follow the contours of the floater (3) in a downward direction into the device. A power device (8) is provided and includes a propeller to achieve in-flow and outflow of the device. The device further comprises a central tube (c) 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 (c).
