Partial nitritation providing a suitable effluent for subsequent anammox is a critical step in a
two-stage autotrophic nitrogen removal system. This study demonstrates an innovative …

Oxidation of ammonium to nitrite rather than nitrate, ie, nitritation, is critical for autotrophic
nitrogen removal. This study demonstrates a robust nitritation process in treating low …

The development of new wastewater treatment processes can assist in reducing the impact
of wastewater treatment on the environment. The recently developed partial nitritation …

We investigated the effects of free ammonia (FA) and free nitrous acid (FNA) concentrations
on the predominant ammonia-oxidizing bacteria (AOB) and the emission of nitrous oxide (N …

Partial nitritation for a low-strength wastewater at low temperature was stably achieved in an
aerobic granular reactor. A bench-scale granular sludge bioreactor was operated in …

Starting up or recovering partial nitritation is a major challenge for achieving or maintaining
stable partial nitritation/anammox (PN/A) during mainstream wastewater treatment. This …

Integrating anaerobic treatment with partial nitritation (PN)/anammox is a promising
technology to achieve energy-efficient wastewater treatment, while partial nitritation of the …

Stable suppression of nitrite oxidizing bacteria (NOB) is one of the major bottlenecks for
achieving mainstream nitrite shunt or partial nitritation/anammox (PN/A). It is increasingly …

The goal of this study was to compare the microbial ecology, gene expression, biokinetics,
and N2O emissions from a lab-scale bioreactor operated sequentially in full-nitrification and …

Advances in research and technological development in the field of wastewater treatment
encourage the implementation of engineered autotrophic nitrogen removal (ANR) systems …
