Abstract

The wet oxidation process e.g. for the purification of waste waters, is carried out with an oxidizing agent containing at least 60% oxygen. The employment of liquid oxygen eliminates the need to install expensive compression units. The addition of ozone improves the reactivity of the oxidation reaction. The addition of organic substances to the waste waters can give autogenous heating.
