ABSTRACT:
A water treatment device is disclosed which includes a floating structure that is submerged in the water to an adjustable depth and has an adjustable orientation in the vertical plane. The device supports an operative unit including a propeller driven by a submersible motor, and a decompression chamber having at least one air inlet connected to a suction pipe that emerges above the open surface of the water, the decompression chamber having an air outlet as well. The propeller is entirely outside the decompression chamber. A hub of the propeller is hollow and communicates with the outlet of the decompression chamber and with the ambient. A conventional rotation seal device ensures the seal between the hub and the fixed part of the operative unit.
