Abstract
An apparatus for mixing gas and liquid is disclosed. The apparatus includes a draft tube having a gas conduit, a liquid inlet and a gas-liquid outlet, and an impeller rotatably mounted within the draft tube. The gas can be entrained into the liquid by rotation of an impeller having relatively high angular velocity, which generates relatively low axial velocity of the liquid and relatively low angular velocity of the liquid. Floats may support the impeller and the impeller may maximize aeration of the liquid.
