The Swiss Federal Office for the Environment (FOEN) currently conducts the project Strategy Micropoll in order to develop a strategy to reduce the input of organic micropollutants from domestic wastewater into Swiss surface waters. The project started in 2006 and was finished by the end of 2010. Results from this project led into the development of the VSA-Plattform Verfahrenstechnik Mikroverunreinigungen.
Ozonation is tested in two full-scale experiments at WWTP Regensdorf and WWTP Lausanne (STEP Vidy). The pilot study in Regensdorf was successfully completed in October 2008 while the study in Lausanne started in May 2009. Besides these full-scale experiments three smaller pilot studies with PAC are conducted at Eawag, WWTP Lausanne and WWTP Kloten-Opfikon (supported by laboratory experiments at Eawag).
Residues of medicinal products, pesticides, biozides and other chemicals can adversely affect the environment and human health already in low concentrations. These micropollutants are increasingly detected in our waters not least due to improved analytics. Precautionary measures are needed to prevent future stresses on our waterbodies. Therefore, the German Environment Agency (UBA) has analysed entry pathways, named critical substance characteristics and proposed a combination of measures consisting of measures at the source, in use and for wastewater treatment serving the objective of comprehensive water protection.
