  • Aeration of water is employed to remove the various dissolved gases like carbon dioxide and oxidizes metals like iron, manganese, hydrogen sulfide, and volatile organic chemicals (VOCs).
  • Aeration also helps in removing dissolved metals through oxidation, the chemical combination of oxygen from the air with certain undesirable metals in the water. Once oxidized, these chemicals fall out of the solution and become particles in the water and can be removed by filtration or flotation.
  • The efficiency of aeration depends on the amount of surface contact between air and water, which is controlled primarily by the size of the water drop or air bubble.
