The removal of selected Polycyclic Aromatic Hydrocarbons (PAHs) (i.e., phenanthrene, fluoranthene and pyrene) as well as a mixture of Linear Alkylbenzene Sulfonates (LAS) in three bench top Sequencing Batch Reactors (SBR) with a 2 L working volume were examined. The bioreactors were fed with increasing concentrations of these compounds, spiked in synthetic domestic wastewater over a time period of 48 days with a loading rate of 3 L.d-1 at 20°C.
In general the reactor operation was marginally affected by the presence of xenobiotics and at every pulse increase in the influent concentration, a respond in no less than three days was followed by a relative increase in the biodegradation and metabolism rate in the reactors and a decrease in effluent concentration to previous low levels. Percent removal of PAHs varied for each compound from an average of 93.7±5.4%, 95.8±2.1%, 76.8±10.3% and 89.3±4.5% for phenanthrene, fluoranthene, pyrene and the sum of these compounds respectively. Furthermore, percent removal of C10-C13 LAS homologues was found to be 95.4± 5.0 for C10, 96.9± 3.5 for C11, 96.0± 5.1 for C12 and 93.7± 8.5 for C13.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)
© Lexxion Verlagsgesellschaft mbH (6/2025)
In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
