Abstract

The potential of decomposing pollutants in supercritical water lies in the complete conversion (total destruction) of persistent, anthropogenic waste materials. The obstacles in the technical application are due to the highly corrosive reaction medium and the precipitation of salts. The concept of the SUWOX-facility is based on a corrosion-resistant double wall reactor the material of which is adapted to the respective compounds of the waste water, and a system pressure of 70 MPa to obtain high fluid densities which lead to high salt solubilities. The process was assessed positively in external evaluations. The report deals with investigations carried out within the scope of an industrial cooperation over a period of three years sponsored by the German Federal Ministry of Education and Research (BMBF)"*. The aim is the development of the SUWOX process into an industrial application scale. After the proof of the successful destruction of pollutants in industrial waste water the investigations concentrated on the development of an application-oriented plant as well as on an economic oxidant supply. It is reported about the conceptions investigated, the steps of development and the results obtained. Based on these results a technological plant has been developed and constructed, which is to be regarded as the preliminary stage of an industrial pilot plant for the disposal of waste water containing biocides.
