Removal of pharmaceutical residues at Nolhaga wastewater treatment plant
During 2021 Alingsås municipality investigated two options for the removal of pharmaceutical residues; ozonation in combination with GAC filtration and biological filtration with BAC. They decided to complement chemical analysis with effect-based methods when evaluating the removal efficiency in the two treatment lines.
Effect-based methods for drinking water monitoring
“Knowledge about cocktail effects is limited, and as interest in reusing wastewater for drinking water purposes increases, it is crucial to use all available tools to monitor water quality.”
Wastewater treatment and recipient water impact
“We were able to draw conclusions that were previously not possible. For example, we were able to quantify that conventional wastewater treatment removes >80% of toxic effects, including known and unknown substances and combined cocktail effects.”
