Industrial Pumps > Aerator > Jet Aerator

The activated sludge process has gained widespread acceptance in biological wastewater treatment. Role of aeration is to provide oxygen to micro-organisms. Oxygen is highly needed in wastewater treatment plant, for the variety of requirements. Jet aeration is one of the methods to provide oxygen for biological degradation of organic materials and oxidation of dissolved minerals and very important requirement is keeping the solids in suspension. The jet aerator system is based on the venturi - nozzle principle, introducing atmospheric air in water. Jet aerators are suitable for small to medium size sewage plant and depths up to 6 meters.


  • Extremely simple installation, even in a flooded tank
  • Ideal for mixing combined with aeration of wastewater containing sewage,
  • organic industrial effluent, slurry etc
  • No need for compressed air supply as it is self-aspirating
  • Can supply oxygen for aeration in breakdown or overload circumstances
  • Low noise level compared to surface systems
  • No aerosol effects
  • Can be used where water levels vary
  • Special structures such as bridges, not needed


  • Equalization tank
  • Sequential batch reactor treatment plant
  • Ponds aeration
  • Aerobic digester
  • Homogenization tanks
  • Ideal for cleaning of storm tanks
  • Used in balance tanks to mix effluent while the
  • addition of oxygen helps prevent septicity
