GRK 546: Elimination of Endocrine-Disrupting Substances From Waste Water

点击翻译按钮获取中文摘要

The research training group AGEESA inquires into various processes related to the elimination of endocrine-disrupting substances from sewage. AGEESA aims at knowledge about possible performance improvements of treatment plants. Since conventional mechanical-biological waste water treatment plants cannot remove endocrine-disrupting substances to a satisfactory extent, more innovative procedures are tested concerning their retention and elimination capacity.AGEESA focuses on the employment of membrane technology in biological waste water treatment, which effects higher concentrations of activated sludge and a higher sludge age than conventional activated sludge processes. This may also improve the degradation of persistent substances such as endocrine disrupters. Additionally, this kind of biological treatment dispenses with final sedimentation, since the biomass is retained by micro- or ultra-filtration membranes. Taking advantage of the high affinity of immobilised antibody proteins, AGEESA's biological team investigates into the development of antibody filters. The projects are supported by scientists who will develop special chemical trace analysis and bioassays.
