A lagoon is a pond where residential or industrial wastewater is placed and treated using natural and biochemical processes. Many small rural communities may have lagoons for their wastewater treatment.  Sewage pumping companies may have lagoons on their property where they place the waste they collect from septic systems.

Lagoons provide sewage treatment due to their low maintenance requirements and high efficiency compared to other wastewater treatment options.

Lagoons can be have aeration or non-aeration (anaerobic) depending on the type of wastewater to be treated.

Anaerobic lagoons mostly treat animal wastes from farms.

Aerobic lagoons are more common and they could be fully aerated or partially aerated. They are also referred to as facultative lagoons.

Facultative lagoons are used for treating low to medium strength wastewater from municipal and industrial sources.

Both types of lagoons contain algae which are essential for treating the wastewater.

The top layer contains dissolved oxygen in both aerated and facultative lagoons. The latter also contains an intermediate anoxic layer where the oxygen level varies from the highest level at the top to an anerobic zone at the bottom.

The oxygen in aerated lagoons could be controlled technically by mechanical technologies. Naturally, it depends on seasonal factors including temperature.

Aquatic Aeration Solutions has a variety of aeration systems to treat wastewater in lagoons.

Depending on the size and type of lagoon will determine the system required to improve treatment of the sewage.

Surface Aeration

High-performance surface aerators dramatically push high volumes of water into the air.

This process increases the overall health of your water and keeps it thoroughly mixed. Introducing oxygen and water movement breaks up stratification, eliminates odor, discourages algae growth, and promotes a healthy aquatic environment.

These self-contained units deliver up to 3.0 lbs of O2 per horsepower per hour of operation, making

Kasco surface aerators the most dependable, and efficient units on the market.

Surface Aerators are available as 1/2, 3/4, 1, 2, 3, and 5HP units.

Diffused Aeration

What is Diffused Aeration? In diffused aeration, oxygen is mixed with the wastewater to allow the anaerobic bacteria to digest biosolid particles in the water. The purpose is to introduce air into the water, which increases the wastewater's dissolved oxygen content.
Aquatic Aeration Solutions has diffused aeration systems that provide air from 4 to 12 diffuser assemblies, allowing the maximum design capabilities to increase oxygen into a lagoon for effective treatment of sewage or wastewater.
