Journal ArticleDOI
Removal of selected pharmaceuticals, fragrances and endocrine disrupting compounds in a membrane bioreactor and conventional wastewater treatment plants.
TL;DR: Eight pharmaceuticals, two polycyclic musk fragrances and nine endocrine disrupting chemicals were analysed in several waste water treatment plants and the SRT is an important design parameter and its impact on achievable treatment efficiencies was evaluated.
Journal ArticleDOI
The solids retention time-a suitable design parameter to evaluate the capacity of wastewater treatment plants to remove micropollutants.
TL;DR: Investigations lead to the conclusion that low effluent concentrations can be achieved in WWTPs operating SRTs higher than 10 days, which corresponds to the requirements forWWTPs situated in sensitive areas according to the urban wastewater directive of the European Community in moderate climatic zones.
Journal ArticleDOI
Relevance of the sludge retention time (SRT) as design criteria for wastewater treatment plants for the removal of endocrine disruptors and pharmaceuticals from wastewater.
TL;DR: An approach is described to determine comparable removal rates for different activated sludge systems based on mass balance and SRT to allow comparison and evaluation of the removal efficiency of different layouts and concepts in wastewater treatment.
Journal ArticleDOI
Energy requirements for waste water treatment.
Karl Svardal,Helmut Kroiss +1 more
TL;DR: Waste water will never be a relevant source of energy as long as the authors' primary energy consumption is in the range of several kW/inhabitant, and this argument is strongly supported by economical considerations as the fixed costs for waste water infrastructure are dominant.
Journal ArticleDOI
What is the potential for utilizing the resources in sludge
TL;DR: The reliability of this disposal route for the treatment plant operator depends on several major pre-requisites: reliability in regard to hygiene, reliability in regards to long-term soil protection public acceptance, and acceptance by all parties involved in sludge application.
