Sulfur Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula ...

compounds dissolved in water are not necessarily dangerous, but can give the water a bad taste or foul smell. These compounds can be removed in several ways, the most effective being by exposure to

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

Aeration Aeration (also called aerification or aeriation) is the Systems engineering process, process by which air is circulated through, mixed with or solvation, dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration proces ...

in the water. This can be achieved by pumping air into the water, allowing it to bubble to the surface; or by a fountain jet agitating the water. Both these methods create an agitated, large amount of surface area between the water and the air, thus allowing transfer of gases. Wave action on the shores of large bodies of water can provide aeration of the water in the vicinity, thus providing enhanced oxygenation which can benefit various aquatic lifeforms.
