How can the positive effects of the WWTP upgrade be measured?

How can the positive effects of the WWTP upgrade be measured?

Numerous biotests and biomarkers are used to assess the impact of the upgrade of the Falkenstein WWTP on the water quality of the Dünnern. The quality of communities and the occurrence of antibiotic resistance are also taken into account. The measurements prior to the upgrade show clear differences between the water quality upstream and downstream of the WWTP outflow. Significant improvements are expected as a result of the upgrade.

Info sheet on washing and cleaning agents

Info sheet on washing and cleaning agents

Washing and cleaning agents are regularly used in every household and thus end up in waste water and ultimately in sewage treatment plants. But which of the substances they contain are dangerous for the environment? And how can we protect it as well as possible - despite the use of detergents and cleaning agents? A new info sheet gives more details.
