Wastewater treatment plants (WWTPs) consume high amounts of energy which is mostly
purchased from the grid. During the past years, many ongoing measures have taken place …

Direct nitrous oxide (N 2 O) emissions during the biological nitrogen removal (BNR)
processes can significantly increase the carbon footprint of wastewater treatment plant …

We present an assessment of greenhouse gas emissions from urban wastewater treatment
plants in Europe. We propose a quantification in terms of emission factors (kilograms of …

Nitrous oxide (N 2 O) emitted from wastewater treatment plants has caused widespread
concern. Over the past decade, people have made tremendous efforts to discover the …

A literature analysis of 158 papers published in international peer-reviewed journals
indexed by the Thomson Reuters Web of Knowledge from 1994 to 2013 showed that CO 2 …

Simultaneous nitrogen and phosphorus removal in winter is one of the great challenges in
wastewater treatment processes due to the poor bioactivity of microbial communities. In this …

Ammonium removal from source water is usually inhibited by insufficient carbon sources
and low temperature in Northeastern China. A strain Y16 was isolated from oligotrophic …

Nitrous oxides (N 2 O) emissions contribute to climate change and stratospheric ozone
depletion. Wastewater treatment is an important, yet likely underestimated, source of N 2 O …

This study aims to identify sources of per-and polyfluoroalkyl substances (PFAS) to
wastewater treatment plants (WWTPs) and reveals previously undescribed variability in daily …

During nitrogen removal in conventional activated sludge processes, nitrous oxide can be
emitted. With a global warming potential of 298 CO 2-equivalents it is an important …
