Abstract

The invention concerns a device to be used in a submersible turbine aerator comprising a housing (4) with a rotating impeller (5) and which is connected to air. A pump impeller (6) is arranged outside the housing (4) in front of the turbine impeller (5) for creating an additional flow away from the turbine inlet. <IMAGE>
