<p>Water oxidation plant for waters especially fish ponds comprising a centrifugal pump the partly in water immersed rotor (4) of which being bowl-shaped and having a suction inlet in the bottom, and having above and concentric with the rotor (4) a fixed likewise mainly bowl-shaped shield (2) dispersing the sucked-in water to all sides. On the inner side of the rotor (4) above the water surface being fastened at least one oblique blade (5) below which said blade(s) (5) is (are) found one or several holes (6) in the wall of the rotor (4). When the rotor rotates water will flow over the blade (5). Hereby a vacuum will form below it causing surrounding air to be sucked in through the hole (6) and mixing with the water.</p> |
