TL;DR: A super high-rate performance with nitrogen removal rate (NRR) of 74.3-76.7 kg-N m(-3) day(-1) was accomplished in the lab-scale ANAMMOX UASB reactors, which was 3 times of the highest reported value.

TL;DR: The heterotrophic denitrification prevailed in the UASB reactor, and became the dominant reactions when high influent COD/NO(2)(-)-N ratios of 2.92 were applied.

TL;DR: The collection of floating granules, breaking them into small pieces and then returning to the anammox reactor proved an effective control strategy and the volumetric removal rate was finally up to 16.5 kg N m(-3) d(-1) after the control strategy was put into use.

TL;DR: The evidence from transmission electron microscopy showed that the morphology and ultrastructure of the Anammox cells in both the reactor enrichments was different, and a record super high volumetric nitrogen removal rate of 45.24 kg-Nm(-3) day -1 was noted after the operation of 230 days.

TL;DR: Vigorous anaerobic ammonium oxidation (anammox) activity was realized by seeding with diverse sludge contents and analysis based on 16S rDNA sequencing confirmed that Candidatus "Brocadia" was the dominant population in the enriched biomass.

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.

TL;DR: The anammox metabolism and its factors were critically reviewed so as to form biofilm/granules for retaining anamm ox bacteria in sewage treatment to make sewage treatment energy-neutral or energy-positive.

TL;DR: In this article, an overview of the practical implementation of autotrophic nitrogen removal is presented, and the different nitrogen removal processes are compared in terms of operational conditions and a direction for future work is provided.

TL;DR: 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.

TL;DR: An integrated system of anammox-based process and microbial fuel cell is proposed for sustainable and energy-positive wastewater treatment and researches on technological development for solving remaining problems are summarized.
