Advanced wastewater treatment (WP3)

Demonstrate advanced wastewater treatment technologies (ozone, activated carbon) for the removal of active pharmaceutical compounds.

1. Pharmaceutical removal at full scale


  • Evaluation and process optimization of a full-scale ozonation system at the wastewater treatment plant in Linköping


  • Evaluation of a full-scale ozonation system and validation of the prior pilot study
  • Demonstration and optimization of different control strategies for a stable and economic pharmaceutical removal
  • Monitoring of relevant pharmaceuticals
  • Perform various ecotoxicity tests to evaluate possible impactss of the by-products potentially formed in ozonation
  • Close co-operation with the local water authority in order to evaluate the outcomes in respect of adequate risk reduction
  • Exchange of information with operators of other full- or lage-scale ozonation systems

2. Flexible use of existing infrastructure


  • Flexible use of the existing infrastructure for better removal of pharmaceuticals in times of low additional treatment demands


  • An expert group will help the operator of the wastewater treatment plant in Kalundborg to establish and optimize flexible use of the existing ozonation plant
  • Improve the ozone dosing strategy as well as the operation of the moving bed biofilm reactors (MBBRs)
  • Monitoring of pharmaceuticals and their ecotoxicity
  • Frequent exchange of information with other operators and related water authorities

3. Comparison of post-treatment options


  • Comparison of different post-treatment options


  • Comparison of different biological ozonation post-treatment options, especially in respect of ecotoxicity but also the transformation products of relevant pharmaceuticals and water quality parameters
  • Applied ozonation post-treatment options include full-scale MBBRs (Linköping and Kalundborg), pilot-scale filters (dual media, granular/biological activated carbon, Berlin) and pilot-scale constructed wetlands (Berlin)
  • Optimization of a micro-sieve unit in order to extract the loaded powdered activated carbon from the water (Helsinki)

4. Optimization and control of advanced treatment


  • Provide a guideline for operators and water authorities based on current knowledge and best practical recommendations
  • Optimization of full-scale ozonation process control and MBBR operation


  • Application and evaluation of different process control strategies for ozonation systems with the goal of a stable and economic operation
  • Frequent exchange of operators´ experiences on their individual progress to allow transnational knowledge transfer
  • Systematic investigation of MBBRs in order to find optimal conditions for the further removal of pharmaceuticals and possible ozonation by-products

5. Output

General guideline for operators and water authorities on how to plan, start, operate and control advanced wastewater systems
