Trace substances in waters / 2026
Wolfsburg becomes a model region for wastewater treatment
Cleaner water in the Aller river, in groundwater, and in agricultural areas – that is the goal of a joint project between Wolfsburg’s wastewater treatment facilities and the Fraunhofer Institutes UMSICHT and ISI. This is to be achieved with the help of a fourth treatment stage at the Wolfsburg-Stahlberg wastewater treatment plant. For the first time, the combination of membrane filtration with a regenerable adsorbent resin stage and activated carbon will be tested. This is expected to eliminate trace substances much more effectively and efficiently in the future. Concurrently, measures at Wolfsburg Hospital will reduce pollution from X-ray contrast agents.
