Microbial nitrite oxidation is the primary pathway that generates nitrate in wastewater
treatment systems and can be performed by a variety of microbes: namely, nitrite-oxidizing …

In sewer systems where anaerobic conditions are present, sulfate-reducing bacteria reduce
sulfate to hydrogen sulfide (H 2 S), leading to sewer corrosion and odor emission. Various …

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 …

Nitritation facilitates the application of anaerobic ammonium oxidation (Anammox)-based
processes for cost-efficient nitrogen removal from wastewater. This study proposed light …

Nitrous oxide (N2O) emissions account for the majority of the carbon footprint of wastewater
