The LOPROX process is an established wet oxidation process well suited for the treatment of industrial wastewater. It operates catalytically in an acidic environment using oxygen fed into it. The reaction conditions ensure low investment and running costs. The LOPROX process is an attractive alternative to other methods of organic sludge disposal. Investigations in the laboratory and on an industrial scale show that it can also be used in the decomposition of sludge (sewage sludge). Sludge can be mineralized and sewage sludge is deactivated by means of acid catalytic wet oxidation.
