Aerators add oxygen to water by pumping air or water into the waterbody, either at the surface or the floor. This circulates the water, encouraging oxygenated top-waters to sink to the bottom and deoxygenated bottom-waters to rise to the surface. Here at the surface, aeration takes place through gas exchange between the air and the water, whereby oxygen enters the water and “bad” gases (e.g. methane, hydrogen sulphides) exit the water.
