Abstract
A submerged aerator is provided with a motor-pump assembly installed submerged, supported by a floating structure of a central articulation of a vertical supporting tube and rotating vertical shaft, where the aerator is provided with two propellers, also called rotors, which promote mixing and suction of atmospheric air for incorporation in the effluent, and a upper driving assembly, mounted outside the effluent and on the floatation structure, which enables the motor-pump assembly performing a partial rotating movement under the effluent due to the geometry of the crank rod system.
