• Assessment of variation in qPCR analysis biological nitrogen removal microbiome. Comparison results between labs highlights the limitations with comparability. The impact DNA extraction was highest followed by choice primers. extent variability depends upon sample type. differed for each target microorganism. Quantitative PCR (qPCR) is broadly used as gold standard to quantify microbial commu...

Ammonium removal from wastewater is a crucial step in treatment. Presently employed technologies based on nitrification/denitrification and partial nitritation/anammox principles require oxygen for the nitrification step, are therefore still not yet fully satisfied with application practice. In recent years, biological ammonium oxidation coupled ferric iron reduction (feammox) has been proposed...

The reduction in N2O emissions is an important task the control of wastewater treatment plants. Since local operating conditions, especially inside biofilms, are usually not known, models tool development and implementation strategies. For a pilot-scale nitrifying biofilm reactor SBR, different operational strategies to reduce autotrophic nitrous oxide (N2O) formation were developed tested by a...
