What is a unidirectional aerator?

A unidirectional aerator is a wastewater mixing and aeration solution for sequencing batch reactors, sludge storage tanks, and aerated basins and lagoons.

The Ecoprocess unidirectional aerator (formerly known as Oxijet) has none of the hassles of traditional systems. There is no piping to install, no costly blowers, and no wasted space to house and protect added equipment.

Our submersible jet system can be fixed to a base, guide mounted, or attached to a floating pontoon. All models offer adjustable jet inclination and a heating element that ensures superior performance, even during harsh winters.

Where are our unidirectional aerators used?

The Ecoprocess unidirectional aeration system is most often a solution for:

  • aerated basins and lagoons
  • sequencing batch reactors
  • sludge management tanks
  • stabilization ponds
  • upgrades to faulty aeration systems

How do our unidirectional aerators work?

The Ecoprocess unidirectional aerator includes a unique venturi assembly that plays a central role in its operation.

When the system’s submersible jet pump shoots wastewater through the venturi assembly, it creates an area of low pressure around the nozzle inlet. This pressure differential forces air above the surface to be drawn in through an inlet pipe.

As wastewater exits the venturi assembly, its pressure increases to match the pressure inside the system’s diffuser pipe.

Wastewater in the diffuser pipe mixes with aspirated air. This mixture is then powerfully ejected as a jet of fine air bubbles, effectively aerating and mixing a wide area.
