Post-doc position at Empa, Switzerland - N2O production from nitritation-anammox

The Laboratory for Air Pollution/Environmental Technology at Empa, Switzerland offers a 36-month Postdoc position on N2O production from nitritation-anammox. The postdoc at Empa will collaborate with scientists at University of Basel (Prof. Dr. Moritz Lehmann), and Eawag in Dübendorf and Kastanienbaum (Dr. A. Joss and Dr. H. Bürgmann) to advance our understanding of the nitrogen metabolism in pure and mixed anammox cultures.
The overarching goal of the SNF Sinergia project is to develop an optimized nitrogen removal process for full-scale wastewater treatment using nitritation-anammox systems with stable operation, high N removal efficiency and minimized greenhouse gas emissions.

Work at Empa will focus on the identification of major biogenic or abiotic N2O production pathway(s) in nitritation-anammox using 15N and 18O labelling and natural abundance studies.
Therefore also the isotopic composition of N2O from potentially related inorganic pathways will be determined. Gaseous emissions from lab and pilot scale reactors will be monitored using QCL absorption spectroscopy, FTIR spectroscopy as well as mass spectrometry. Activities will be coordinated with activities at Eawag Dübendorf on process design / modelling, University of Basel on the inorganic nitrogen pathway, and Eawag Kastanienbaum using molecular biological techniques to study the anammox consortia.
