Physico-Chemical Effluent Treatment

The effectivity of oxidation processes initiated by radicals, created by heterogeneous catalysis and by high pressure process

Wet oxidation offers a possibility to reduce the pollutant content in the water. Alternative wet oxidation processes with heterogeneous catalysis and cavitation initiation are developed. The catalytic process is able to lower the pollutant content of highly contaminated sewages up to 70 %. The process is convinient for industrial use. Cavitation reduces the pollution level only up to 30 %. So the use of cavitation in industrial scale sewage cleaning plants under the parameter conditions tested in the project has no chance to be realized in the industrial practice as by technical as by economical reasons.
