Oxyduct-Oxidation of hydrogen sulphide

Pure Oxygen for H2S degradation


Instead of compressed air, pure Oxygen is injected into the waste water pipeline using the Oxyduct process. Since pure Oxygen, unlike air, is not diluted by Nitrogen, the amount of gas dissolved is relevant higher. Oxyduct thus ensures an adequate Oxygen depot in the pressured pipeline, suppressing anaerobic digestion processes. Also the formation of organic Sulphides and Mercaptans is prevented by the introduction of Oxygen. As a result Oxygen is more effective than iron salts but does not cause any unwanted deposits in the pipeline or at regulation devices. In addition pure Oxygen is superior to hydrogen peroxide or nitrate due to lower costs and higher efficiency.



The Oxyduct process, which has been applied in practice for many years, makes prevention of hydrogen sulfide formation and corrosion in sewer networks easy and economical.
