The term is, however, frequently applied to carbonated water.
Purpose of Aeration
Sulfur compounds dissolved in water can give the water a bad taste or foul smell (though they are not necessarily dangerous to health.) These compounds can be removed in several ways, the most effective being by exposure to chlorine gas. However, aeration can also be effective if the amount of sulfur in the water is relatively low.
During aeration, water is pumped into a non-pressurized tank and agitated. This physically removes many of the sulfur compounds, which are then vented. Exposure to oxygen in the air also oxidizes some of the compounds, creating atomic sulfur which can be filtered from the water.
Aeration is also an effective means of removing radon from water.
