Aerators are devices that bring air into contact with water, often by spraying water through air or forcing air through water. Aerators are used to oxygenate soil to ensure growth of grass or crops, or to oxygenate bodies of water to ensure the health of fish stocks. Aerators are also used in water treatment plants to oxygenate wastewater for positive microbial action.
Spraying aerators are used to aerate ponds, lakes, or tanks. A spray aerator consists of an aerator pump connected to a spray nozzle. A pond aerator or lake aerator can use a variety of floating aerators, such as paddlewheels and injectors to provide oxygenated air.

Aerators are also used to treat wastewater. These aerators may be submersible pumps, surface mixers, or a system that pipes air bubbles through a wastewater tank. Aerators are also used to condition sewage or wastewater for residential applications. A septic tank aerator uses an electric motor and fan blade assembly attached to an air shaft with a copper aspirator tip that is submerged in the liquid. The electric motor is mounted on brackets above the water line and turns the air shaft and aspirator, mixing the liquid in the septic tank to introduce dissolved oxygen.
Lawn aerators and turf aerators are used to aerate soil, and are devices that can be pushed like a lawnmower, or attached to a tractor and pulled from behind. A pull-type turf aerator is a series of long tines mounted on a wheeled axle that rotates as the aerator is pulled behind a tractor, churning up the soil to a preferred depth. A push-type or walk-behind lawn aerator typically consists of weighted drum that breaks up dry or heavy soil to a specified depth. Smaller, hand-held tools can also be used for aeration in gardens, borders, or hard to reach areas.
