Energy from wastewater: How does the energy self-sufficient wastewater plant work?

Drehmoment - Der Antriebspodcast

How do you retrofit an existing plant for a green future? Claus Homann is responsible for wastewater management in the municipality of Aarhus in Denmark. Together with Mads Warming from Danfoss, he converted an existing wastewater treatment plant into one of the most modern wastewater plants in the world. The Danes invested in technology: sensors, blowers and frequency converters. This means that the plant is not very different from other existing wastewater treatment plants. It is rather the people who have set themselves the goal of saving energy. In the podcast, Claus reveals how he achieved this and why German plants can also benefit from it.
