Ideal for plants with highly polluted waste water

In its construction form the ejector for the aeration process corresponds to that of a jet ejector. Because organically polluted wastewater requires a high amount of oxygen and also because of the increasing height of modern biological waste water cleaning plants it is energetically more efficient to pre-compress the air mechanically to the hydrostatic pressure prevailing at the installation point of the ejector and to supply it so to the suction connection.

advantages of Körting ejectors:

• maintenance-free - no moving elements
• high oxygen efficiency - Fine bubbles create large contact surfaces between air and water and high turbulence renews these contact surfaces.
• no deposits - The intensive jet flow directed towards the tank floor prevents deposits of biomass.
• straightforward control of oxygen supply
• non-clogging construction - The nozzle diameter defines the narrowest flow cross-section.
• no sealing problems - When the plant is inactive, water can enter the air pipeline without negative effects and when re-started, the ejector’s entraining effect expels any liquid in the pipe.
• design acc. to requirements - Various sizes can be designed and adapted to requirements.
