| Popis: | As a consequence of the EU Water Framework Directive more focus is now on discharges ofhazardous substances from wastewater treatment plants and sewers. Thus, many municipalitiesin Denmark may have to adopt to future advanced treatment technologies. This paper describesa holistic assessment, which includes technical, economical and environmental aspects. Thetechnical and economical assessment is performed on 5 advanced treatment technologies: sandfiltration, ozone treatment, UV exclusively for disinfection of pathogenic microorganisms,membrane bioreactor (MBR) and UV in combination with advanced oxidation. The technicalassessment is based on 12 hazardous substances comprising heavy metals, organic pollutants,endocrine disruptors as well as pathogenic microorganisms. The environmental assessment isperformed by life cycle assessment (LCA) comprising 9 of the specific hazardous substances andthree advanced treatment methods; sand filtration, ozone treatment and MBR. The technical andeconomic assessment showed that UV solely for disinfection purposes or ozone treatment is themost advantageous advanced treatment methods if the demands are restricted to pathogenicmicroorganisms. In terms of sustainability, sand filtration is the most advantageous methodbased on the technical and environmental assessment due to the low energy consumption andhigh efficiency with regards to removal of heavy metals |
