Any suggestions or input that would further enhance or expand the glossary are strongly encouraged.

 

We would like to formally thank and credit such organizations as WQA, AWWA, WEF, Lenntech and other web glossary sources for providing some of the basis and background of this compendium.

Aeration

A water treatment technique that demands oxygen supply, commonly known as aerobic biological water purification. Either water is brought into contact with water droplets by spraying, or air is brought into contact with water by means of aeration facilities. Air is pressed through a body of water by bubbling and the water is supplied with oxygen. Aeration may be used to add oxygen to the water for the oxidation of matter such as iron, or to cause the release of dissolved gases such as carbon dioxide or hydrogen sulfide from the water. The process of aeration may be passive (as when waste is exposed to air), or active (as when a mixing or bubbling device introduces the air).
