change. The practical implementation of anaerobic ammonium oxidation (anammox) …

Chemically enhanced primary treatment (CEPT) followed by partial nitritation and anammox
(PN/A) and anaerobic digestion (AD) is a promising roadmap to achieve energy-neutral …

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 …

Shortcut nitrogen removal holds significant economic appeal for mainstream wastewater
treatment. Nevertheless, it is too difficult to achieve the stable suppression of nitrite-oxidizing …

Although the dose of biocides to sewers could control sulfide and methane production, the
high resistance of sulfate-reducing bacteria (SRB) to biocides would increase dosing …

Granule-based partial nitritation and anaerobic ammonium oxidation (PN/A) is an energy-
