Waste water treatment approaches in Germany Micropollutants – State of Play in Germany ◮ research and implementation activites in different Federal States ◮ upgrading of an increasing number UWWTDs ongoing ◮ competence centers dedicated to micropollutant elimination: ◮ Baden Württemberg https://koms-bw.de/ ◮ Northrhine-Westphalia https: //www.masterplan-wasser.nrw.de/das-kompetenzzentrum/ October 24, 2018 UWWTD Expert Workshop 1
Waste water treatment approaches in Germany Micropollutants – State of Play in Germany ◮ micropollutants are a complex issue ◮ a broad set of measures required ◮ waste water / rain water important conveyor for micropollutants ◮ advanced waste water treatment one important building block ◮ ozonation and activated carbon proven technologies ◮ important also for water reuse (groundwater and soil protection) ◮ other regulatory areas have to be adressed October 24, 2018 UWWTD Expert Workshop 1
Waste water treatment approaches in Germany Multi-Stakeholder dialoge on the trace substances strategy ◮ started in 2016 ◮ broad participation ◮ first milestone summer 2018 „policy paper with recommendations“ ◮ currently in a second „refinement“ phase October 24, 2018 UWWTD Expert Workshop 2

Waste water treatment approaches in Germany Microplastics – state of play in Germany a lot of research ◮ high political attention in EC and several member states ◮ activities and discussions throughout Europe (f.e. IG Plastics of the EPAs Network) ◮ but honestly still serious knowledge gaps ◮ analytical methods (sampling, sample preparation, detection) ◮ sources and pathways incl. waste water system ◮ concentrations in environmental media ◮ effects ◮ ....

Waste water treatment approaches in Germany Summary Micropollutants ◮ large knowledge base ◮ combination of measures required ◮ production ⇒ use ⇒ EOP ◮ incl. improved Waste Water Treatment ◮ broad political dialog Microplastics ◮ serious knowledge gaps ◮ many research projects ongoing ◮ UWWT state of knowledge (based on proxies and first data) ◮ discharges less relevant ◮ CSO, Rainwater + sewage sludge more important ◮ ISO work towards standardization should be supported October 24, 2018 UWWTD Expert Workshop 5
