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!

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)
