Anaerobic ammonium oxidation (anammox) has been studied extensively while no widely accepted optimum values for nitrite (both a substance and inhibitor) has been determined. In the current paper, nitrite spiking (abruptly increasing nitrite concentration in reactor over 20 mg NO-2-NL-1) effect on anammox process was studied on three systems: a moving bed biofilm reactor (MBBR), a sequencing batch reactor (SBR) and an upflow anaerobic sludge blanket (UASB). The inhibition thresholds and… 
Ameliorating nitrite inhibition in a low-temperature nitritation–anammox MBBR using bacterial intermediate nitric oxide
The long-term sustainability of an anaerobic ammonium oxidation (anammox) process in a moving bed biofilm reactor (MBBR) treating highly concentrated (mean of 740 mg NH4+-N L−1) wastewater was
Inhibition factors and kinetic model for anaerobic ammonia oxidation in a granular sludge bioreactor with Candidatus Brocadia
Abstract Varying pH and high levels of nitrite have major inhibitory effects on anaerobic ammonium oxidizing bacteria (AnAOB) and are known to interfere with the anaerobic ammonia oxidation (Anammox)
Influence of elevated Zn (II) on Anammox system: Microbial variation and zinc tolerance.
TLDR
High Zn (II) improved the microbial diversity and lowered the Candidatus Kuenenia abuandance to 1.38% from 20.89%, while extracellular polymeric substance (EPS) climbed up initially and then decreased.
Impacts of different morphologies of anammox bacteria on nitrogen removal performance of a hybrid bioreactor: Suspended sludge, biofilm and gel beads.
TLDR
Two batch tests indicate that mainly suspended sludge and biofilm contributed to the anammox process, with the specific total inorganic nitrogen removal rate reaching 10.55 and 4.05 mg·(gVSS·h)-1, respectively, and a pore-forming technique was developed to produce more channels for gas dispersion inside the gel beads.
Removal of Nitrogen Oxide Based on Anammox through Fe(II)EDTA Absorption
Nitrogen oxides in flue gas cause considerable environmental and health problems. In this study, the NO removal through Fe(II)EDTA absorption based anaerobic ammonium oxidation (Anammox) reduction
Evaluation of the impact of dissolved oxygen concentration on biofilm microbial community in sequencing batch biofilm reactor.
TLDR
The dynamics of key bacterial communities in the SND system were highly influenced by the DO concentration, and real-time PCR indicated that the amount of ammonia-oxidizing bacteria (AOB) and nitrite-oxidation bacteria (NOB) matched the Nitrospirales and Nitrosomonadales abundance well.
Performance of Anammox Processes for Wastewater Treatment: A Critical Review on Effects of Operational Conditions and Environmental Stresses
The anaerobic ammonium oxidation (anammox) process is well-known as a low-energy consuming and eco-friendly technology for treating nitrogen-rich wastewater. Although the anammox reaction was widely
Efficient feeding strategy to enhance the start-up of anaerobic ammonium oxidation process in an anaerobic up-flow biofilm column reactor
Anaerobic ammonium oxidation (anammox) performed by bacteria that belong to the Planctomycetes phylum could potentially be applied to treat wastewater with high ammonium content. However, anammox
Fast start-up of anammox process with mixed activated sludge and settling option
TLDR
The results demonstrated the feasibility of seeding mixed activated sludge to start-up an anammox SBR by settling option and revealed Candidatus Brocadia was detected as predominant functional microbes in the anamm ox SBR.
Novel design and optimisation of a nitritation/anammox set-up for ammonium removal from filtrate of digested sludge
TLDR
An innovative design of anammox-based set-up was employed to improve sludge settling under high ammonium load and suspended, weakly and firmly attached sludge exhibited the highest heterotrophic, nitrifying, and anamm ox activities, respectively.

Effects of nitrite inhibition on anaerobic ammonium oxidation
TLDR
The results showed that the nitrite concentration in a reactor must be less than 274-mg N/L in order to prevent a decrease in the anammox activity, which occurred when the gel carriers were soaked in nitrite solutions with concentrations greater than 274 in a batch test.

Abstract A batch test procedure, based on manometric measurements, was used to study the Anammox process, in particular the inhibition due to nitrite and the effects of hydroxylamine and hydrazine,
The effect of sulfide inhibition on the ANAMMOX process.
TLDR
The ANAMMOX performance recovered under sulfide-S level of 8 mg L(-1) with a steady NRR increasing speed, linear relationship between the NRR and operation time, and the synchronic reduce in the specific ANAM MOX activity and the biomass extended the apparent doubling time of the nitrogen removal capacity and decreased biomass growth rate.
Nitritating-anammox biomass tolerant to high dissolved oxygen concentration and C/N ratio in treatment of yeast factory wastewater
TLDR
The anammox process was suitable for the treatment of yeast factory wastewater containing relatively high and abruptly increased organic C/N ratio and dissolved oxygen (DO) concentrations and showed yeast factory-specific organic N compound-betaine and inorganic N simultaneous biodegradation.
The effect of nitrite inhibition on the anammox process.
TLDR
The recovery after exposure indicates that the adverse effect of nitrite is reversible and thus inhibitory rather than toxic in nature, and that nitrite rather than nitrous acid is the actual inhibiting compound.
Evaluation of activity and inhibition effects on Anammox process by batch tests based on the nitrogen-gas production
In order to assess the applicability at industrial-scale of the anaerobic ammonium oxidation (Anammox) process it is necessary to study the toxic effects on the maximum specific Anammox activity

TLDR
Based on the model, INi is the main inhibiting species of the anammox process at pH > 7.1 and 561 mg INi-N l−1 and 0.117 mg FNA-N-L−1, which are the most common conditions occurring in field applications of anamm ox.

TLDR
Statistical modelling of chemical parameters revealed the roles of several optimized parameters needed for a stable process and improved total nitrogen removal rate and increased anammox bacteria activity.

TLDR
Using previously grown nitrifying biofilm matrix for anammox enrichment has some benefits over starting up the process from zero, such as less time for enrichment and protection against severe inhibitions in case of high substrate loading rates.
