Submersible Aerators Jet Aerators And Mixers For Treatment Basins
Machines that put oxygen into a basin and keep the contents moving, combining pump, blower and gas liquid mixer in one unit that works under water.
The Range
Five Machines For Oxygen Transfer And Mixing
Submersible and immersible aerators draw their own air, the jet aerator pushes a mixed stream across the basin, and the submersible mixers keep solids in suspension without adding air.

- Municipal sewage treatment works running activated sludge basins
- Industrial wastewater plants with equalisation and oxidation tanks
- Operators of stabilisation ponds and lagoons
- Plants that need mixing without an external blower house
Problems It Solves
A blower house costs more than the basin needs
A self priming aerator integrates pump, blower and mixer in one submerged unit, so there is no separate blower, no air main and no diffuser grid to maintain.
Solids settle in the corners
Submersible mixers move the whole basin volume so sludge stays in suspension instead of forming a deposit that reduces capacity.
Oxygen transfer is poor
The star type impeller and stator disperse air into bubbles of around 100 microns, which increases the surface area available for transfer.
Why This Line
How These Machines Work
One Unit In The Basin
Pump, air blower and gas liquid mixer in a single machine that sits on the basin floor or hangs from a float.
Air Drawn By Vacuum
Impeller rotation creates a vacuum in the stator that draws air down the pipe, so no compressor is required.
Mixing And Aeration Together
The same unit that aerates also circulates the basin contents, which matters in activated sludge and stabilisation duty.
Application Scenarios
Where They Are Installed
Activated Sludge Treatment
Supplying oxygen and mixing in the aeration tank, including pre-aeration and sludge stabilisation stages.
Oxidation Ponds And Lagoons
Floating or floor mounted units that keep a large shallow volume aerobic.
Neutralisation And Flotation
Gas floats, neutralisation and ozone treatment stages where the mixture must be kept in motion.
Industries Served By This Line
Selection Guide
Sizing Aeration For A Basin
Measure The Basin
Volume, depth and shape decide how many units are needed and where they sit. Depth matters as much as volume.
State The Oxygen Demand
Load in kilograms of BOD per day, or the process stage, tells us how much oxygen has to be transferred.
Choose Fixed Or Floating
Floor mounted on a base for fixed basins, float mounted where level varies or the basin cannot be drained.
Plan Lifting And Service
Guide rails and a lifting arrangement let the unit come out for service without draining the tank.
Answers
Submersible Aerators And Mixers FAQ
How fine are the bubbles?
Water and air mix inside the impeller and the gas is dispersed into small bubbles of about 100 microns in diameter, which is what drives oxygen transfer.
Do I need a separate blower?
No. The aerator is self priming for air: impeller rotation creates the vacuum that draws air down the pipe, so pump, blower and mixer are one machine.
Can the unit be mounted on a float?
Yes. It can sit on the bottom of the aeration pool or be fixed to a floating body, depending on basin depth and level variation.
What is the difference between an aerator and a submersible mixer?
The aerator adds air and mixes. The mixer only moves the contents, which is what you want in anoxic zones and in balancing tanks where air is not wanted.
Which processes are these used in?
Pre-aeration, activated sludge treatment, sludge stabilisation, gas flotation, neutralisation, ozone treatment, oxidation ponds and general liquid mixing.
