As the first full scale facility of its type, an ozonation plant is being implemented in Switzerland. The WWTP Neugut in Dübendorf cleans the wastewater from Dübendorf, Dietlikon, Wangen-Brüttisellen, and Wallisellen. The Neugut plant will be the first full scale ozonation facility at a municipal WWTP in Switzerland. The launch is expected for early 2014. The Neugut plant is a tailor-made application developed in cooperation with Eawag and the surrounding municipalities to protect the water quality of the nearby river and wells. DEMEAU accompanies the operation of the ozonation at the WWTP Neugut, observing barriers and promoting examples of the application of this innovative technology.
