Sewage treatment plants can hardly remove anthropogenous trace substances like pharmaceutical residues. An innovative process combination now allows to remove 70-95% of these trace substances. They are eliminated using a combination of non-thermal plasma and ultrafiltration. This technology is now market-ready and will soon be implemented in large-scale plants.
Anthropogenous trace substances like pharmaceutical residues, hormone preparations or pesticides negatively affect water bodies and their ecosystems. These compounds can enter the human body by drinking water produced from rivers. Additionally, there are multi-resistant germs emerging from antibiotic residues. Conventional sewage treatment plants cannot remove these substances or can only remove small parts. Available processing technologies for the 4th treatment stage are based on ozone and/or activated carbon. Both procedures are not only expensive but also an environmental burden.
A unique procedure combines non-thermal plasma and ultrafiltration. After a thorough testing period in the sewage treatment plant in the Austrian city Bad Reichenhall it can now be implemented in large plants. The innovative technique removes between 70 and 95% of trace substances and 99.999% of germs. Another advantage is that this method is up to 50% more energy efficient and saves resources.
Three innovative key points are the process combination, the ultrafiltration and the oxidation level. The combination of ultrafiltration with a downstream oxidation process is unique and was not available on the market. Compared to other procedures, more variations of trace substances can be removed. The ultrafiltration demands less space than other procedures and needs up to 50% less energy. By separating particles larger than 20 nanometers, potentially hazardous germs can be removed from the wastewater. Last but not least, the innovative oxidation level needs less energy than conventional oxidation technologies and doesn’t produce any kind of residues.
