Noun
1. the process of exposing to air (so as to purify)
(hypernym) natural process, natural action, action, activity
(derivation) air out, air, aerate
2. the act of charging a liquid with a gas making it effervescent
(hypernym) change of state
(derivation) oxygenate, oxygenize, oxygenise, aerate

the technique of injecting air or gas into a fluid. For example, air is injected into drilling fluid to reduce the density of the fluid.

Air is needed for composting bacteria to thoroughly break down plant material. Aeration can be accomplished by regular turnings of the compost pile, preferably weekly. A pitch fork or spading fork can be used to turn a pile.
Plastic perforated pipes can be laid throughout the pile to increase air movement.
If the temperature of a pile drops, the compost needs either moisture or aeration.

 Say it
Preparation of a saturated solution of air gases by either spraying the solution in air or by bubbling air through it.

The process by which atmospheric air enters the soil. The rate and amount of aeration depends on the size and continuity of the pore spaces and the degree of water logging.

The technique of injecting air or gas in varying amounts into a fluid for the purpose of reducing hydrostatic head.

Exposing to the action of air, like blowing air through water before discharging to a river.

A process which promotes biological degradation of organic matter in water. The process may be passive (as when waste is exposed to air), or active (as when a mixing or bubbling device introduces the air).
