Insights

With the Passavant® Surface Aerator Mammutrotor® Aqseptence Group offers you a universal solution which has been especially developed for aeration, circulation and stir mixing processes. More than 8,500 installations with a total length of approximately 52 km have meanwhile been deployed worldwide and the Mammutrotor® has become the byword for economic and reliable surface aeration.
Function Oxygen transfer occurs during the operation of the Mammutrotor® by means of an intensive turbulence of the phase boundary between the air and the wastewater/activated sludge mixture, directly at the aeration rotor. The flow energy which is simultaneously introduced ensures the requisite blending of the activated sludge, wastewater and oxygen. This ensures sedimentation-free operation in tanks with a depth of up to 3.5 m. In deeper tanks of up to 8 m, the mixing process is supported by additional agitators which allow an intermittent mode of operation, in addition to the continuous mode. The oxygen enrichment efficiency and the cost effectiveness of the system are further enhanced by the optional installation of guide baffles mounted transversely to the outflow of the aeration rotors.
