Aqua-Lator® Surface Aerators

Cost-effective, high oxygen transfer efficient aeration
​The Aqua-Lator® surface aerator, introduced in 1963, is considered the first floating mechanical aerator for wastewater treatment applications. The powerful pumping action of the surface aerator transfers oxygen by breaking up the wastewater into a spray of particles, creating more surface area for atmospheric pressure to drive oxygen into the wastewater. At the same time, the oxygen-enriched water is dispersed and mixed, resulting in highly effective aeration for wastewater treatment. An optional accessory for Aqua-Lator Surface Aerators, is the Mist Eliminator Spray Containment Dome providing mist and spray control for cold temperatures.



  • ​Aerated lagoons
  • Stabilization basins
  • Sequencing Batch Reactors (SBR)
  • Activated sludge treatment plants
  • Aerobic digestion

 Key Features & Benefits

  • ​Low operating costs
  • Trouble-free performance
  • High oxygen transfer efficiency
  • Resistant to corrosion and abrasion


 Mist Eliminator Spray Containment Dome

The Mist Eliminator Spray Containment Dome is an optional accessory that adds to the versatiltiy and the wide range of uses of the Aqua-Lator high-speed floating surface aerator.  In cold weather  conditions the domed cover retains heat and enables the aerator to continue operating during periods of lower temperatures.
