Abstract
A skimming and separation device includes an outer casing defining a compartment, a floater that provides a skimming function, the floater being attached at its lower side to a vertically arranged bellow allowing the floater to adapt flow into a substantially circum volume and to move from an upper position with essentially no flow into the compartment to a lower position allowing flow of water and debris to follow the contours of the floater in a downward direction. The device further includes a power device with a propeller, the power device being 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. At least one peripheral flow deflecting member achieves a rotational movement of downward directed flow of water and debris, in a horizontal plane and around a vertical longitudinal center axis of the device.
