Waterways - Fourth cleaning stage should make water cleaner
Wastewater in Schleswig-Holstein is supposed to be better treated in the future. Environment Minister Tobias Goldschmidt (Greens) informed himself about a fourth purification stage today during a visit to the Rendsburg Clarification Plant in Fockbek (Rendsburg-Eckernförde district). The state is supporting the pilot project with nearly 2.4 million Euros. "With the funding guideline and this first pilot plant in Schleswig-Holstein, we are supporting all municipalities in the state and helping them early on to be prepared for the upcoming EU requirement," said the minister.
According to the information provided, wastewater is currently mechanically, biologically, and chemically treated. However, there are still trace substances such as medicines, cosmetics, and household chemicals in the water.
The fourth purification stage, which costs 8.4 million Euros, is supposed to go into operation in spring 2025 according to the Environmental Ministry's statements. An ozone plant will then convert trace substances in the wastewater into more bindable and degradable substances using ozone. In the following filtration, these substances will be reduced. Ozone consists of three oxygen atoms and is a strong oxidizing agent.
Wastewater in Schleswig-Holstein, currently treated using mechanical, biological, and chemical methods, often contains residual substances like medications, cosmetics, and household chemicals. These substances will be further addressed with the implementation of a fourth purification stage in the Rendsburg Clarification Plant, supported by Tobias Goldschmidt and the state with a fund of nearly 2.4 million Euros. This advanced stage will utilize an ozone plant to convert these trace substances into more manageable forms, ultimately improving the quality of water released into local water bodies in the Rendsburg-Eckernförde District.
