 ersichtlichen Querschnitt zu ersehen, die Form eines W. Die Fig. 4 zeigt in Ansicht und Querschnitt eine mehrfache Welle. Die Fig. 5 und 6 zeigen Vogelflugprofile und die Fig. 7 ein Vogelschwanzprofil. Allen Profilen ist gemeinsam, dass bei gewählter Breite des Belüftungselementes die Fläche durch mehrfache Profilierung erheblich vermehrt ist.

 apparent cross-section to be seen, the shape of a W. Fig. 4 shows in view and cross-section a multiple wave. FIGS. 5 and 6 show bird flight profiles and FIG. 7 shows a bird's tail profile. What all profiles have in common is that if the width of the ventilation element is selected, the area is significantly increased through multiple profiles.

PATENTANSPRUCH : Belüftungsrotor für Flüssigkeiten bestehend aus einer horizontalen Welle und darauf über ihre ganze Länge radial oder annähernd radial angeordneten, teilweise in die Flüssigkeit tauchenden Belüftungselementen, insbesondere zur Grundwasserbelüftung und zur Abwasserreinigung nach dem Schlammbelebungsverfahren, dadurch gekennzeichnet, dass auf der Rotorwelle eine Vielzahl im Abstand voneinander stehender gleicher stabförmiger, durch die Flüssigkeit hindurchdrehender Belüftungselemente von W-förmi- gen, wellenförmigen oder vogelflugartigen Profilen befestigt ist, die durch ihre Profilform und/oder besondere Störkörper beim Durchlauf durch die Flüssigkeit Saugwirbel erzeugen. PATENT CLAIM: Aeration rotor for liquids consisting of a horizontal shaft and aeration elements arranged radially or approximately radially over its entire length, partially immersed in the liquid, in particular for groundwater aeration and wastewater purification according to the sludge activation process, characterized in that a large number of spaced apart elements are positioned on the rotor shaft the same rod-shaped, through the liquid rotating ventilation elements of W-shaped, wave-shaped or bird-like profiles is attached, which generate suction eddies due to their profile shape and / or special disruptive bodies when passing through the liquid.
