The traditional biological nitrogen removal (BNR) follows the conventional scheme of
sequential nitrification and denitrification. In recent years, novel processes such as …

Anaerobic ammonium oxidation (anammox) has been extensively investigated for cost-
efficient nitrogen removal from wastewater. However, the major issues of nitrate (NO 3−-N) …

As a waste management technology which offers environmental benefit and renewable
energy production, anaerobic digestion (AD) has become the preferred technology for the …

Mainstream nitrogen removal via anammox is widely recognized as a promising wastewater
treatment process. However, its application is challenging at large scale due to unstable …

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

Landfill leachate, generated from the wastes in a landfill, is a type of wastewater with high
concentrations of ammonia and organics, causing a serious environmental pollution …

In this study, enhanced nitrogen removal through in situ enrichment of anammox bacteria
was successfully obtained in a full-scale municipal wastewater treatment plant (WWTP). The …

The sulfur autotrophic denitrification (SADN) process is an organic–free denitrification
process that utilizes reduced inorganic sulfur compounds (RISCs) as the electron donor for …

The application of mainstream anammox is highly desirable for municipal wastewater
treatment. However, enrichment of anammox bacteria (AnAOB) is challenging, particularly …

Biological nitrogen removal from sewage via anammox is a promising and feasible
