The nitrogenous compounds present in wastewaters create severe biotic stress and alter the
biodiversity when discharged into aquatic ecosystems. Biological nitrogen removal (BNR) …

To maximize energy recovery, carbon capture followed by shortcut nitrogen removal is
becoming the most promising route in biological wastewater treatment. As the intermediate …

Nitrogen (N) removal in constructed wetlands (CWs) was often challenged by limited
denitrification due to the lack of carbon source, and wetland plants would be more important …

Acidic nitrification is attracting wide attention because it can enable robust suppression of
nitrite-oxidizing bacteria (NOB) in wastewater treatment. This study reports a comprehensive …

Partial nitritation-anammox (PN/A) is a promising deammonification process to develop
energy-neutral wastewater treatment plants. However, the mainstream application of PN/A …

This study proposes a novel strategy of stably enriching anammox in mainstream, based on
the competitive difference to NO 2− between anoxic biofilms and suspended sludge. A …

It is of great significance to start up the anammox process in the most commonly used
anaerobic-anoxic-oxic (A 2/O) process in treating mainstream municipal wastewater …

Wastewater treatment plants (WWTPs) are facing a great challenge to transition from energy-
intensive to carbon-neutral and energy-efficient systems. Biological nutrient removal (BNR) …

The application of anammox in denitrifying biofilter (DNBF) has been proven to be stable
and feasible, but self-enrichment of anammox bacteria (AnAOB) in DNBF is difficult and …

Despite a quick shift of global goals toward carbon-neutral infrastructure, activated sludge
based conventional systems inhibit the Green New Deal. Here, a municipal wastewater …
