What is Lagoon Aeration?
Similar to the activated sludge process, lagoon aeration is typically used in rural areas with small- to large-sized plants. A series of shallow earthen basins (lagoons) act as the aeration basins and holding tanks – it’s in this treatment pond that biological oxidation of wastewaters occur. Although lagoons are often equipped with surface aerators, there are several diffuser systems available specifically for these applications. A well-designed diffused air system uses approximately half as much energy as surface aeration.
Types of lagoon aeration?
At its simplest, lagoon aeration is the process that uses oxygen and mixing to create an aerobic treatment environment.
There are two types: surface aeration and diffused aeration.
Surface aeration is characterized by mechanical equipment floating on the surface of the water, while diffused aeration uses aeration blowers to release bubbles from a point at the bottom of a lagoon.
Benefits of lagoon aeration?
Lagoon aeration is one of the simplest and least expensive waterwater treatment systems, and as mentioned above, is excellent as a lower-cost wastewater treatment option for those in more rural areas. Lagoons typically cost less to construct and operate; they're also simpler to maintain than other systems. While lagoon aeration requires more land than other wastewater treatment methods, this usually isn't an issue in the rural parts of the United States. An added benefit is that they're able to handle light and heavy use , which is ideal for communities that rely on tourism & rental properties.

Additional Wastewater Treatment Applications
Membrane Bioreactors
Membrane bioreactors feature an ultrafine membrane filter installed at the discharge end of a standard aeration basin. Pumps installed on the membrane filters create a slight vacuum and pull the effluent through the membrane. The ultrafine holes in the membrane do not allow the biological microbes to pass through the membrane.
