E-FLEX®-Floating Aerator

The floating version of the proven E-FLEX®-Aeration System for use in waste water ponds or basins where floor mounting and leveling is not possible.

Product Information

Membrane aeration systems are usually permanently installed or removed from the basin floor.

For cases in which floor installation is not possible or only practicable under difficult conditions, INVENT has developed the Floating E-FLEX®-Aeration System, the floating version of the proven E-FLEX®-Aeration System.

Compared to conventional floor-mounted aerators, the Floating E-FLEX®-Aeration System includes the following advantages and properties:

  • Use of the proven, highly efficient Floating E-FLEX®-Aeration System modules
  • Individual aerator chains cover a large area during operation and thus ensure efficient use of the entire tank volume
  • Leveling of individual modules is not necessary
  • Thanks to the use of floating air supply lines, installation is also possible when the basin is full

    Products and Team

    The wide range of INVENT products fulfills all process- and plant dependent requirements for biological wastewater treatment reliably and energy efficient.

    Aeration Systems for Modern Wastewater Treatment

    Applications of the INVENT E-FLEX®-Floating Aerator

    BOD or COD degradation

    Highly efficient supply of oxygen to the microorganisms for BOD and nitrogen elimination.

    The agitation and gassing system acts as a permanent aeration system for biological carbon degradation in aeration tanks. We can react flexibly to fluctuations in freight. The simultaneous circulation by the agitator ensures a homogeneous and deposit-free mixing even with low air supply in the activated sludge tank.

    Lagoon basin

    Highly efficient supply of oxygen to the microorganisms for BOD and nitrogen elimination in waste water ponds, lakes or lagoons with foil sealing.

    BOD degradation/nitrification in conventional activated sludge systems where floor mounting of the aeration system is not possible

    Highly efficient supply of oxygen to the microorganisms for BOD and nitrogen elimination in all aerated tanks where floor mounting of conventional aeration systems is not possible.

    Odor prevention in waste water ponds, lakes

    Efficient aeration in all cases where the introduction of oxygen is necessary to prevent anaerobic conditions and the resulting fermentation gases (H2S, CH4…).
