Abstract

Degradation and adsorption to activated sludge of Bisphenol-A, 17-P-Estradiole and 17-a-Ethinylestradiole B. Strenn, M. Clara & N. Kreuzinger Institute for Water Quality and Waste Management, Vienna University of Technology, Vienna, Austria Abstract Several substances which have estrogenic effects on aquatic organisms were observed at relevant concentrations in the effluent of wastewater treatment plants. In order to evaluate and optimise the efficiency of wastewater treatment plants a basic knowledge of the behaviour of these substances during the different steps of wastewater treatment has to be derived. Investigations on degradation and adsorption behaviour of Bisphenol-A (BPA), 17-0-Estradiole (Ez) and 17-a- Ethinylestradiole (EE2) were conducted. Adsorption experiments were performed with activated and inactivated sludge. The sludge was taken from a low loaded wastewater treatment plant. The results showed no significant difference between activated and inactivated sludge during the firs
