Ecology and adaptation of denitrifiers across genomes and environments
… of the nitrogen cycle, including losses from anaerobic ammonia oxidation (anammox) and denitrification. The stepwise reduction of nitrate to nitrite, nitric oxide, nitrous oxide, and N2 gas, denitrification can be performed by diverse taxa and acts as a major sink of fixed nitrogen within low …

Nitrification process in integrated fixed-film activated sludge (IFFAS) system
The ammonia released from wastewater is a key factor in detrimental environment concerns such as eutrophication. Nitrogenous waste is most commonly removed from wastewater through biological means, typically involving the use of ammonia oxidizing bacteria (AOB), nitrite oxidizing bacteria (NOB), …

Microbial Communities Associated with Phosphoclast-bearing Sediments of the Benguela Upwelling Zone
… known to carry out nitrification and/or anammox (anaerobic ammonia oxidation) were also well-represented. Our phosphoclast extraction, however, contained a distinct microbial community from those observed in the modern sediments. We observed both an enrichment of certain common microbial classes …

Deammonification Process Kinetics and Inhibition Evaluation
… originating from the process of dewatering anaerobically digested solids. This liquid, also knows as centrate, reject water or sludge liquor, can cause an increase of up to 25% in ammonia loading. The recently discovered anaerobic ammonia oxidation (anammox) process is a major breakthrough …

Mathematical Modeling for Nitrogen Removal via a Nitritation: Anaerobic Ammonium Oxidation-Coupled Biofilm in a Hollow Fiber Membrane Bioreactor and a Rotating Biological Contactor
Mathematical models of a nitritation: anaerobic ammonia oxidation (anammox)-coupled biofilm in a counter-diffusion hollow fiber membrane bioreactor (HFMBR) and a nitritation: anammox-coupled biofilm in a co-diffusion rotating biological contactor (RBC) were developed and implemented using AQUASIM. …

Startup and Pilot Testing of MBBR and IFAS Partial Denitrification/Anammox Processes
… removal (BNR) process that can be used to remove ammonia (NH3) and NOx from wastewater. This process is a combination of partial denitrification (PdN), which serves to reduce nitrate (NO3) to nitrite (NO2), and anaerobic ammonia oxidation, or anammox (AMX), which uses the nitrite as an electron …

Treatment of High-Strength Nitrogen Wasetewater With a Hollow-Fiber Membrane-Aerated Biofilm Reactor: A Comprehensive Evaluation
… HFMBR systems with redox (aerobic/anoxic/anaerobic) stratification, because the DO concentration will determine the nature of the microenvironments, the microorganisms present, and the metabolisms that occur. During the second phase of the research, the coupling of two autotrophic …
