Answer 1

Aeration brings water and air in close contact in order to remove dissolved gases (such as carbon dioxide) and oxidizes dissolved metals such as iron, hydrogen sulfide, and volatile organic chemicals (VOCs). Aeration is often the first major process at the treatment plant. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments.
