ABSTRACT
The paper summarises the definition of an extended biokinetic model dedicated to micropollutant degradation in wastewater treatment and the parameter estimation methodology for this model. Additionally it describes results on experimental parameter estimation for two target micropollutants, naphthalene disulfonate (2,6-NDSA) and benzothiazole sulfonic acid (BTSA). Subsequently the parameterised model is applied to real operational data from two laboratory-scale (MBR) installations. The work presents the full chain of theoretical model development, model analysis and practical application to case study data for micropollutants.

The EU-project P-THREE started with the establishment of analytical methods for persistent polar pollutants (P3) and quality assurance, followed by screening of P3 in influents and effluents of known wastewater (WW) treatment plants (TP), receiving waters and tap water produced thereof in several European countries. A final selection of analytes for further studies has been performed. Model MBR reactors have been constructed and an optimisation on synthetic wastewater spiked with P3 (linear alkylbenzene sulfonates (LAS), naphthalene sulfonates) has been performed. An initial dynamic modelling of treatment processes has also started. Advanced oxidation process (AOP) treatment has been done in groundwater with isoproturon and nonylphenol ethoxylates (NPEO). The analysis of individual P3 and potential degradation products was also performed. An integrated systeme analysis of the WW treatment processes has also been initiated.

This paper deals with the development of a description of membrane bioreactor systems, focussing on wastewater treatment and removal of specific low concentration persistent organic pollutants (e.g. persistent polar pollutants--P3 compounds). In the present work we offer a basic model, adapted to Membrane Bioreactor (MBR) conditions, which reflects the biodegradation of recalcitrant (organic) substances. We put a particular focus on organic aromatic pollutants and demonstrate a model parameter estimation approach, with experiments carried out for linear alkylbenzene sulphonates (LAS).
