Anaerobic lagoons are artificial bodies of water designed to contain and treat wastewater. They use a combination of physical, biological, and chemical processes to allow aerobic and anaerobic microorganisms to break down organic matter in the wastewater. This process of wastewater treatment is known as anaerobic lagoons.

Anaerobic lagoons are used in a variety of industries, including sewage treatment, industrial process water treatment, and food processing waste treatment. During the process of anaerobic digestion, bacteria consume organic matter and produce biogas, which is composed of methane, carbon dioxide, and other trace gases. This biogas can be used as a renewable energy source or displaced as combustible gas for heating or power generation. The solid fraction left behind is known as sludge.

The design of an anaerobic lagoon depends on the type of wastewater that needs to be treated, as well as the type of biomass available. For example, lagoons designed for treating industrial process water may require a different design than those designed for sewage treatment. In general, lagoons can either be shallow and shallow-sloped, deep and deep-sloped, or shallow-sloped and deep-sloped. The lagoons are usually lined to prevent seepage of the wastewater into the surrounding environment, and they can be topped with floating covers to prevent evaporation.

Anaerobic lagoons are a low-energy and low-cost method of wastewater treatment, and they can be used in both rural and urban areas. Although the process of anaerobic digestion produces biogas, it also produces odors, which can be a nuisance. To reduce odor from the lagoons, covers can be used to contain the gas and the sludge can be dried to reduce odors. Additionally, the lagoons can be equipped with aeration systems to help reduce odors.
