High nitrogen removal performance at moderately low temperature utilizing anaerobic ammonium oxidation reactions
TLDR
The nitrogen removal performance of an anaerobic biological filtrated (ABF) reactor, filled with porous polyester nonwoven fabric carriers as a fixed bed for anammox bacteria, was tested at moderately low temperature and showed that an appropriate nitrite concentration in the influent and a shorter HRT resulted in high nitrogen conversion rates.About:

The inhibition of the Anammox process: A review
TL;DR: In this paper, a detailed review of previous researches on the inhibition of Anammox processes is presented, where the effect of inhibitory substances, such as substrates (ammonia and nitrite), organic matter (nontoxic organic matter and toxic organic matter), salts, heavy metals, phosphate and sulfide, are commonly present in the practical applications.

Long-term stability of partial nitritation of swine wastewater digester liquor and its subsequent treatment by Anammox.
TL;DR: Partial nitritation using inhibition of free ammonia and free nitric acid is an effective technique for the treatment of high concentrations of ammonium in wastewaters and the stability of its long-term operation was investigated.

The sequencing batch reactor as a powerful tool for the study of slowly growing anaerobic ammonium-oxidizing microorganisms
TL;DR: It is suggested that the SBR could be used for the enrichment and quantitative study of a large number of slowly growing microorganisms that are currently out of reach for microbiological research.
Journal ArticleDOI
Anaerobic ammonium oxidation discovered in a denitrifying fluidized bed reactor
TL;DR: Anaerobic ammonium oxidation is a new process in which ammonium is oxidized with nitrate serving as the electron acceptor under anaerobic conditions, producing dinitrogen gas, and has been given the name ‘Anammox’ (anaerobic ammonia oxidation), and has be patented.

Autotrophic growth of anaerobic ammonium-oxidizing micro-organisms in a fluidized bed reactor
TL;DR: An autotrophic, synthetic medium for the enrichment of anaerobic ammonium-oxidizing (Anammox) micro-organisms was developed and Acetylene, phosphate and oxygen were shown to be strong inhibitors of the Anammox activity.

Key Physiology of Anaerobic Ammonium Oxidation
Marc Strous,J.G. Kuenen,Jetten +2 more
TL;DR: The physiology of anaerobic ammonium oxidizing (anammox) aggregates grown in a sequencing batch reactor was investigated quantitatively and the anammox process was completely inhibited by nitrite concentrations higher than 0.1 g of nitrogen per liter.
