Wet Air Oxidation — University of Illinois Urbana-Champaign

Wet Air Oxidation (WAO, oxidation in aqueous phase) has proven to be an effective technology for ultimate destruction of a variety of these hazardous wastes. In 1984, the USEPA specified WAO as a "Best Demonstrated Available Technology (BDAT)" for many land-banned wastes under the Hazardous and Solid Waste Amendments to the Resource ...

What Is Wet Oxidation? (with picture) - wiseGEEK

Wet oxidation is a chemical process for removing organic contaminants from wastewater streams. The process involves heating the contaminated water to high temperatures, and injecting air at high pressures. Reactions of air with the contaminants will oxidize them to common gases like carbon dioxide, which are separated later from the water stream.

Zimpro® Wet Air Oxidation - Water Online

Wet air oxidation (WAO) is the oxidation of soluble or suspended components in water using oxygen as the oxidizing agent. When air is used as the source of oxygen the process is referred to as wet air oxidation (WAO). The oxidation reactions occur at temperatures of 150º C to 320º C (275º F to 608º F) and pressures from 10 to 220 barg (150 ...

How does wet air oxidation work? WAO occurs in the aqueous phase at relatively low temperature conditions. When wastewater, air, and heat are combined, the unique nature of water results in oxidation reactions that would normally occur at much higher temperatures if oxidized in air. The higher the temperature, the higher the oxidation potential.
