On 2nd October 2012 the foundation stone was laid in the Neugut water treatment plant for the first ozonation facility in Switzerland.
On the basis of the findings of the Micropoll project of the Federal Office for the Environment (FOEN), which Eawag was closely involved in, a change to the water protection law was submitted for consultation in April. This provides for around 100 of the 700 water treatment plants in Switzerland to be fitted with special purification technology for micropollution. The ozonation facility at the Neugut waste water treatment plant will supplement the existing technology to eliminate organic micropollution from waste water from the Dübendorf, Wangen-Brüttisellen, Dietlikon and Wallisellen municipalities. Eawag will be able to analyse the new process directly at the water treatment plant through various research projects, and thereby gain important insights for the practical application of the technology. These projects will involve researchers from process engineering, environmental chemistry and ecotoxicology.
