A sewage lagoon aerator supplies oxygen to lagoons and oxidation ponds, maintaining aerobic conditions for biological treatment of municipal and industrial wastewater. Surface and submersible aerators are used to transfer oxygen and keep the lagoon mixed.
How a lagoon aerator works
- Oxygen transfer – The aerator draws air and disperses it into the lagoon water.
- Mixing – Flow from the aerator keeps solids suspended and distributes oxygen across the lagoon.
- Biological treatment – Aerobic microorganisms degrade organic pollutants in the water.
- Circulation – Multiple aerators are positioned to cover the lagoon surface area.
Types of lagoon aerators
| Type | Best suited for |
|---|---|
| Surface aerator | Large lagoons, shallow water, simple installation |
| Submersible aerator | Deeper basins, combined mixing and aeration, retrofit |
| Diffused air system | Fine bubble aeration with blower and diffusers |
Typical applications
- Municipal sewage lagoons and oxidation ponds;
- Industrial wastewater lagoons;
- Manure and agricultural waste lagoons;
- Seasonal or intermittent lagoon operation.
Frequently asked questions
What is a sewage lagoon aerator?
A sewage lagoon aerator adds oxygen to lagoon water and keeps it mixed, supporting aerobic biological treatment of wastewater.
How does a lagoon aerator work?
It draws air and disperses it into the water, transferring oxygen while the resulting flow mixes the lagoon and keeps solids in suspension.
What are the types of lagoon aerators?
Common types are surface aerators, submersible aerators and diffused air systems; selection depends on lagoon depth, size and oxygen demand.
How many aerators does a lagoon need?
The number depends on lagoon volume, organic loading and oxygen transfer per unit; aeration design covers total oxygen demand and mixing.
What is a surface aerator for a lagoon?
A surface aerator floats or mounts at the water surface, drawing air in and dispersing it, suitable for large shallow lagoons.
Can a submersible aerator be used in a lagoon?
Yes. Submersible aerators are used in deeper lagoons and basins where combined mixing and aeration are needed.
How much does a lagoon aerator cost?
Cost depends on aerator type, power, lagoon size and installation. Send your lagoon volume and loading for a preliminary budget estimate.
Do you supply sewage lagoon aerators?
Yes. PollutionCtrl supplies surface and submersible lagoon aerators for municipal and industrial wastewater lagoons.
