What is Aeration? Aeration is the process by which air is circulated through, mixed with or dissolved in a liquid or substance. Aeration brings water and air in close contact in order to remove dissolved gases and to oxidize dissolved metals, including iron, hydrogen sulfide, and volatile organic chemicals (VOCs).
