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.

March 29, 2022Artificial floods mimick natural flows to mobilise and transport sediment downstream, reshape the river and reinstate important habitats for native aquatic insects and fish. Improved outcomes can occur when these artificial floods converge with natural flows and sediment delivery from unregulated tributary streams further down the valley.
