May 4, 2022What has been a purification process in wastewater treatment plants for decades can also be used decentrally or semi-centrally as a recycling process for nutrients. Early separation of "solid and liquid" plays a key role here. It allows for flexible solutions in terms of process technology, especially in the treatment of urine. New studies also show that the processes can be used not only for human urine, but also for that of cows or pigs.

May 2, 2022Ozonation is an established treatment process to remove micropollutants from wastewater. However, since unstable toxic reaction products can be formed in the process, biological post-treatment is necessary. Results from the Ecotox Centre and Eawag show how well different post-treatment methods reduce ecotoxicological effects. The combination of ozonation and activated carbon proved to be the most effective.

April 14, 2022Chlorination of drinking water reduces infections – and it changes the composition of the intestinal flora of young children, as a study published today in “Nature Microbiology” shows. The results indicate that the diversity of the intestinal flora isn’t reduced and bacteria associated with gut health are increased.
