Features and Benefits

Features

  • Aluminum Construction
  • No Moving Parts
  • Open Interior



Benefits    

  • Corrosion resistant
  • Light weight eases installation
  • Economical to operate
  • Maintenance free
  • Eliminates fouling

Cascade aerators are best applied for oxidation of ferrous iron by addition of oxygen followed by detention and filtration.  Ideal for iron concentrations above 10 ppm as the open structure eliminates fouling from iron precipitation.  They also increase dissolved oxygen at the end of wastewater plants.
