Lagoon Aeration
The aeration system is the heart of an aerated lagoon. Learn about the fundamental purpose of aeration and how it impacts treatment.
Fundamentals of Aeration
- to supply the required oxygen to the metabolizing microorganisms and
- to provide mixing so that the microorganisms come into intimate contact with the dissolved and suspended organic matter.”
Mixing, not O2, has a greater impact on treatment
- The level of mixing in your lagoon determines how well the metabolizing microorganisms come into contact with the food (BOD).
- As a result, the level of mixing determines how much can be treated and how quickly.
- The higher the mixing rate, the faster the treatment.
Oxygen Transfer Efficiency
- Aeration options available to lagoons vary in relative efficiency based on clean water testing.
- Fine bubble is among the most efficient technologies, with coarse bubble and surface aeration being the least efficient.
- However, lagoon fine bubble systems can struggle to properly mix the entire lagoon due to sheer volume of water.

In situ sludge reduction
- Multiple sludge reduction studies have been conducted with dual action coarse and fine bubble technology utilized by the Ares.
- Simply by providing more mixing and oxygen to lagoons, sludge can be reduced in place.
- Average level of sludge reduction is 45–50%.
