The EcoJet Aerator

For more than half a century, the EcoJet™ aerator design has provided proven results for municipal and industrial markets throughout the world. With ultimate versatility, no other mechanical aerator is more rugged or more efficient.

The EcoJet™ offers unparalleled performance and superior reliability, low operating costs, and remarkable resistance to environmental conditions that can cause natural wear and damage.

Typical wastewater treatment applications:

  • SBRs

  • Cooling

  • Post aeration

  • Aerated lagoons

  • Activated sludge

  • Equalization basins

The result: Effective wastewater treatment.

Providing powerful pumping action, the EcoJet™ aerator transfers oxygen by breaking up wastewater into a spray of particles. This action creates more surface area for atmospheric pressure to drive oxygen into the wastewater. At the same time, the oxygen-enriched water is dispersed and mixed. The entire process offers more efficient wastewater treatment for municipalities and industrial applications.

Components

Ultimate wastewater treatment equipment designs.

Specifically designed for optimum efficacy, the EcoJet™ aerator design meets the most demanding operational requirements. The high-speed aerator provides ultimate versatility with modular units that can easily be added, repositioned or upgraded, allowing for greater adaptability and flexibility to maintain efficiencies throughout changing conditions.
