Anammox-mediated systems have attracted considerable attention as alternative cost-
effective technologies for sustainable nitrogen (N) removal from wastewater. This review …

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

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 …

Heterotrophic bacteria (HB) are generally prevalent in anammox-based processes, but their
functional and ecological roles in partial nitritation-anammox (PN/A) process treating high …

In deammonification systems, nitrite-oxidizing bacteria (NOB) suppression and nitrous oxide
(N2O) mitigation are two important operational objectives. To carry out this multivariable …

Data Analytics is being deployed to predict the dissolved nitrous oxide (N 2 O) concentration
in a full-scale sidestream sequence batch reactor (SBR) treating the anaerobic supernatant …

Wastewater treatment plants of the future aim at energy autarky. This could potentially be
realized through a high-rate activated sludge (HRAS) process for organics (expressed as …

The development of low carbon treatment processes is an important issue worldwide. Partial
denitrification coupled with anammox (PD/A) is a novel strategy to remove nitrogen and …

Highlights•AOB, AOA, and denitrifiers regulate biological and abiotic N 2 O
production.•Genomic and phenotypic variability of N-transforming guilds affect N 2 O …

Gas bubbles are introduced in water to absorb or strip volatile substances in a variety of unit
operations, for example during (waste) water treatment. To calculate the transfer rate of …
