Wastewater treatment – current status
645 municipal wastewater treatment works 83,0000 small sewage works and 8,500
septic tanks 1,200 direct industrial dischargers and
approx. 40,000 indirect dischargers More than 8,000 stormwater holding tanks
and spillways Approx. 70,000 km public sewers,
an estimated 200,000 km of private sewers, approx. 3M domestic connections
High standards in NRW when compared to national and international benchmarks
The Initiative „reine Ruhr“-Background: 50 Million organic compounds 5,000 potentially harmful substances
(German Advisory Council on the Environment)
Improved analytical methods make detection of lower concentrations possible (e.g. pharmaceuticals)
In an industrialized world, the use of anthropogenic substances is indispensable!
Importance for NRW Abstraction of drinking water by bank filtration High industrial density High population density High level of soil sealing High average age of the population
Status quo: micropollutants(Detection of contamination of surface water, raw water and/or drinking water) Volatile halogenated hydrocarbons
1,1,1-Trichlorethane Flame retardants
Phosphoric acid-tris-(2-chlorpropyl)ester Pharmaceuticals
Carbamazepine and diclofenac X-ray contrast medium
Amidotrizoic acid and iopamidol Perfluorinated surfactants (PFT) Complexing agents EDTA and DTPA TOSU (2,4,8,10-Tetraoxaspiro[5.5]-undecane) Sulfolane (organic solvent)
Basis: MNQ!
Example: diclofenac (Project Material Flow Modelling)

Various large-scale treatment plants and studies/publications provide the data required for performing an economic cost analysis. sufficient data for estimating the investment costs of wastewater
ozonation differentiated consideration of filtration units lack of long-time experiences concerning operational costs
Aim of the project: „consistent assessment of costs“ based on first operational experiences
Result: Costs of 10-15 ct/m³ fresh water (100,000 p)
