Description:
Aeration is a useful drinking water treatment process. Aeration has been used to remove hydrogen sulfide, methane, radon, iron, manganese, and volatile organic contaminants (VOCs) from drinking water. Aeration is also effective in removing carbon dioxide which directly impacts pH and dissolved inorganic carbon (DIC), the most influential parameters on lead and copper solubility. As a result, aeration can be an effective corrosion control strategy presuming the initial pH and DIC are appropriate. Mineral precipitation brought about by water quality changes resulting from aeration may present operational constraints under some conditions. Aeration produces very consistent water quality, and may be advantageous especially to smaller utilities, because of the relatively low costs, and simple operational and maintenance needs.
