Anoxic ammonium oxidation (anammox) is an energy-efficient nitrogen removal process for
wastewater treatment. However, the unstable nitrite supply and residual nitrate in the …

Wastewater treatment is a major source of anthropogenic nitrous oxide (N2O) emissions.
However, the current emission estimations rely on a uniform emission factor (EF) proposed …

Partial nitritation/anammox (PN/A) has been one of the most innovative developments in
biological wastewater treatment in recent years. With its discovery in the 1990s a completely …

Energy efficiency optimization is crucial for wastewater treatment plants (WWTPs) because
of increasing energy costs and concerns about global climate change. Energy efficiency …

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

Throughout the 20th century, the prevailing approach toward nitrogen management in
municipal wastewater treatment was to remove ammonium by transforming it into dinitrogen …

Nitrous oxide (N2O) emissions from wastewater treatment plants vary substantially between
plants, ranging from negligible to substantial (a few per cent of the total nitrogen load) …

Many wastewater treatment plants in the world do not remove reactive nitrogen from
wastewater prior to release into the environment. Excess reactive nitrogen not only has a …

Nitrogen contamination remains a severe environmental problem and a major threat to
sustainable development worldwide. A systematic analysis of the literature indicates that the …
