TL;DR: In this paper , the authors used a unique strategy to recover deteriorated single-stage partial nitritation-anammox (PNA) systems and explored the mechanism of rapid performance recovery.
Journal ArticleDOI
How phenol stresses anammox for the treatment of ammonia-rich wastewater: phenomena, microbial community evolution and molecular modeling.
TL;DR: In this article , phenol was fed to the system of anaerobic ammonia oxidation (anammox), and the possible inhibitory mechanism was speculated using the characterization of granular sludge, analysis of microbial community and molecular docking simulations.
Journal ArticleDOI
Stable nitrogen removal in the novel continuous flow anammox system under deteriorated partial nitrification: Significance and superiority of the anaerobic-oxic-anoxic-oxic operation mode.
TL;DR: In this article , a continuous push-flow anaerobic-oxic-anoxic-oxic (AOAO) process treating sewage was used to restore the nitrogen elimination performance rapidly under deteriorated PN.
Journal ArticleDOI
Rapidly recovering and maintaining simultaneous partial nitrification, denitrification and anammox process through hydroxylamine addition to advance nitrogen removal from domestic sewage.
TL;DR: In this article , the authors showed that the addition of hydroxylamine was an effective strategy to recover and economically maintain the SPNDA process for advanced nitrogen removal from domestic sewage.
Journal ArticleDOI
Promotion of nitrogen removal and microbial enrichment on anammox by exogenous substance addition: A critical review
TL;DR: In this article , the authors summarized the current reports based on various metals (Zero-valent iron, Fe 2+ , Fe 3+ , iron-based material, Mn, Ni, K, Ca), organic matter (fulvic acid, humic acid), inorganic matter (biochar, activated carbon, graphene, zeolite, inorganic carbon), reaction intermediates (hydroxylamine, hydrazine) and N-acylhomoserine lactones influencing anammox by enhancing the functional bacteria and electronic delivery, obtaining higher biological retention and specific Anammox activity (SAA).

TL;DR: An analysis of the metabolic opportunities of anammox bacteria suggests alternative chemolithotrophic lifestyles that are independent of these compounds, and current concepts are still largely hypothetical and put forward the most intriguing questions that need experimental answers.

Nitric oxide is an obligate bacterial nitrification intermediate produced by hydroxylamine oxidoreductase
TL;DR: The present study implies that aerobic NH3 oxidation by AOB occurs via two obligate intermediates, NH2OH and NO, necessitate revision of a key biogeochemical process and identify a new bioenergetic role for nitric oxide.
