Chapter 04 Aeration SUEZ suezwatertechnologies

In industrial water conditioning, one of the major objectives of aeration is to remove carbon dioxide. Aeration is also used to oxidize soluble iron and manganese (found in many well waters) to insoluble precipitates. Aeration is often used to reduce the carbon dioxide liberated by a treatment process.

How Does Aeration Work? Pure Water Products, LLC

When iron is fully oxidized in alkaline water, iron readily precipitates. Precipitation One of the requirements to successful precipitation is to provide sufficient contact time for the oxygen and minerals to react. For iron removal, it is generally best to have an aeration tank, which provides contact time and a vent to expel excess air.
