Abstract
A skimming and separation device comprising an outer casing (1) provided with constructions to directly or indirectly fasten all parts, defining an open container (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 circum volume and allowing the floater to move from an upper position with essentially no flow into the container (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 bypass member (B) being in fluid communication to an under pressure source via a suction tube (12), such that, during operation, an essentially continuously under pressure suction force is available at the bypass member. The bypass member and a guiding unit arranged in the device are both structured to continuously subject debris and floating pollutions to be accumulated on an upper surface in the skimming and separation…
