What is a unidirectional aerator?
A unidirectional aerator is a wastewater mixing and aeration solution for sequencing batch reactors (SBRs), sludge storage tanks, and aerated basins and lagoons.
Ecoprocess unidirectional aerators (formerly known as Oxijet) are submersible jet systems that reliably deliver oxygen to wastewater in all seasons. Our design uses no blowers, giving you superior – and silent – performance without the high cost of installing and operating a traditional system.
Applications
- aerated basins and lagoons
- sequencing batch reactors
- sludge management tanks
- stabilization ponds
- upgrades to faulty aeration systems
How do our unidirectional aerators work?
Ecoprocess unidirectional aerators include a unique venturi assembly that plays a central role in their 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.
