Abstract

In a device (1) for treating waters in a basin, an operating group (8) is immersed in the water, being supported by two upper floats (3) or simply resting on the bottom of the basin. The operating group (8) has, defined inside it, a chamber inside which it is possible to create a pressure drop by means of a propeller (10) rotating outside the chamber. Two suction pipes (6), which lead to the chamber, emerge at the top above the free surface of the water. The operating group (8) is attached to a base structure (12) which is able to rest on the bottom of the basin. The device (1) may be used in particular to aerate and/or oxygenate (by means of movement) the waters contained in a basin, such as for example a tank for aquiculture, a fish-farming basin or an aeration tank of water purification plants.
