Strategies to minimize micropollutant release in plant effluent  and Fate and occurrence of the selected analytes, microorganisms, viruses and mode of actions in relevant treatment processes

Previous projects (e.g. the EU project Poseidon) showed that conventional wastewater treatment is an insufficient barrier to avoid the release of emerging micropollutants such as pharmaceuticals and personal care products into the aquatic environment. By financing Neptune the European Commission has supported a project with a strong focus on the consequent follow up steps:

  • widening the knowledge of micropollutant occurrence by developing and applying new analytical techniques
  • improving the understanding of the fate of specific emerging pollutants in conventional biological treatment (sorption, biological transformation)
  • breaking new ground in understanding the formation of transformation products
  • comparing and evaluating options for advanced treatment technologies (mainly sorbtion to activated carbon and ozonation) by analyzing the removal efficiency for micropollutants in pilot-scale and full-scale and discussing process technology and control
  • discussing alternative treatment options including source control measures and posttreatment with wetlands

The present deliverable summarizes the key findings of Neptune to this topic. Thanks to the flexibility of the European Commission, it was possible to deliver herewith a single document, joining the scopes of the workpackages 1 and 3: discussing suitable strategies for the removal of micropollutants from wastewater requires understanding the fate of compounds during treatment (WP3) as well as assessing the feasibility of technical process solutions (WP1).
