An aerated lagoon (or aerated pond) is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewaters. [1] [2] [3] [4]
Waste stabilization ponds described here use no aerators. High-performance lagoon technology that does use aerators has much more in common with the activated sludge process. Such aerated lagoons use less area than is needed for traditional stabilization ponds and are also common in small towns. [3]
Aerated lagoons provide less effective mixing than conventional activated sludge systems and do not achieve the same performance level. The basins may range in depth from 1.5 to 5.0 metres. Surface-aerated basins achieve 80 to 90 percent removal of BOD with retention times of 1 to 10 days. [26]

Aeration is provided by the rotating action, which exposes the media to the air after contacting them with the wastewater, facilitating the degradation of the pollutants being removed. The degree of wastewater treatment is related to the amount of media surface area and the quality and volume of the inflowing wastewater.

Coarse bubble aeration is a type of subsurface aeration wherein air is pumped from an on-shore air compressor. [ 6 ] through a hose to a unit placed at the bottom of the water body. The unit expels coarse bubbles (more than 2mm in diameter), [ 7 ] which release oxygen when they come into contact with the water, which also contributes to a ...
