<p>A device is described for aeration of the hypolimnion in stagnant waters, which device is equipped with a rising tube, falling tube and transfer chamber connecting the rising tube and falling tube. The transfer chamber is incorporated in a floating platform. The rising tube and the falling tube are designed as floats which can be flooded and emptied, which can be suspended from the floating platform with essentially horizontal tube axes. The rising tube and the falling tube can be connected via detachable couplings to connection branches of the transfer chambers prior to pivoting from the horizontal floating position into a vertical operating position, this operating position being set by flooding the floats. <IMAGE></p> |
