1. Working Plan for WG 2 - Methods of Treatment Overall Aspects and Details for 2006

2. Action Programme General Content Assessing Treatment efficiency –Conventional / New technologies –Different processes involved –´Deriving the information needed to Evaluate potential for particulate processes and technologies Compare technologies Investigate / improve technologies –Requirements for Monitoring for different purpose Information from Treatment plant needed (Characterization) Sampling design –Scheme with potential of techniques

3. Action Programm General Content Biological processes –Pathways (Substrate; Co-Metabolism) –Adaptation –Metabolites –Influence of Biocenoses and link to operation conditions / layout of treatment plant –Interaction with matrix / organic matter

4. Action Programme general content Physical / chemical processes –Broad range of processes that can be applied for removal of Xenobiotics Adsorption Filtration Oxidation processes … –Processes can be implemented in both, Wastewater, Stormwater and Drinking water treatment –By-products / residues –Information necessary for life cycle analysis

5. Action Programme general content Modeling –Purpose of monitoring Xenobiotics Effect on treatment Fate of Substances –Use of Xenobiotics Substrate Co-Metabolism –Information needed for modeling –Definition of parameter set for modeling –Definition of experimental setup for obtaining parameters

6. Action Programme general content Substances to be dealt with –Inter-working-group task force to clear this aspect –Within WG2 “model substances” could be used for Calibration of models Validation of experimental setups Filling schemes with treatment steps Spreading of general approach –Same approach for monitoring and evaluation of treatment efficiency on international scale Needs for Research / Research Topics Design of Research Projects Data collection / database

7. Meeting 1 Time: ~April 2006 Location: France / Turkey Topic: General Aspects in assessing removal of Xenobiotics –Agreement on definitions (e.g. “removal”) –Removal pathways as base for mass balance –Definition of processes Physical, chemical Biological –How to describe processes (info necessary) –How to monitor / describe efficiency of processes and treatment steps to make them comparable –Suggestion for standardizing sampling

8. Meeting 1 E.g.: Mass balances –for defining pathways of removal / fate –what information / parameters are necessary to produce mass balance –what processes have to be taken into consideration for mass balance V R X BM s K OM,i k i Q E s i Q ES s i,E X BM K OM,i Effluent Inflow Excess sludge Q IN s i,IN X SS,IND,i Aeration Tank i,E Q E s K SS,E X K D,i

9. Meeting 2 Time: End September 2006 Location: Austria (?) Topic: Review of treatment methods –Implementing criteria from Meeting 1 –Presentation of results from different groups in regard to their work –Classification of information /results in regard to processes defined in Meeting 1 –Consolidation of data

10. Meeting 3 Time: Spring 2007 Location: (?) Topic: Adaptation of Microorganisms to Xenobiotics –Discussion of Mechanisms –Assessment of the effect –Effect on Modeling and Planning
