Feasibility of partial-denitrification/ anammox for pharmaceutical wastewater treatment in a hybrid biofilm reactor.
TLDR
In this article, a novel approach integrating partial denitrification with anaerobic ammonia oxidation (PD/A) in a sequencing biofilm batch reactor (SBBR) was proposed and demonstrated to be efficient to treat the bismuth nitrate and bistuth potassium citrate manufacturing wastewater, containing ammonia (NH4+-N) and nitrate (NO3−-N), which achieved a relatively stable TN removal efficiency of 81.9% to 80.8%.About:

Sustainable upgrading of biological municipal wastewater treatment based on anammox: From microbial understanding to engineering application
TL;DR: In this article , the critical view and comprehensive analysis were offered from the perspective of microbial interactions within partial nitrification-and partial denitrification-based anammox processes, and targeted control strategies were systematically evaluated.

Multiple roles of complex organics in polishing THP-AD filtrate with double-line anammox: Inhibitory relief and bacterial selection.
TL;DR: In this article , a double-line anammox-mediated system, integrating the Partial Nitrification/Anammox (PNA) with Partial Denitrification/ANammox processes in separately sequencing batch reactors (SBRs), was developed to polish the THP-AD filtrate.

A review of anammox-based nitrogen removal technology: From microbial diversity to engineering applications.
TL;DR: In this article , the diversity of anammox bacteria, habitats and characteristics of different genera were compared, and a combined process was developed and optimized on this basis, while a focus for future research was proposed to intensively study the water quality barrier factors of Anammox and its regulation strategies.

Microalgal-bacterial granular sludge process for sustainable municipal wastewater treatment: Simple organics versus complex organics
Bin Ji,Y. Shi,Murat Yilmaz +2 more
TL;DR: In this paper , the average COD, nitrogen and phosphorus removal efficiencies for wastewater containing simple/complex organic matter were 75.2/84.9, 96.6/89.3% and 76.2 /85.3%, respectively, showing that a carbon-neutral target for wastewater treatment by microalgal-bacterial granular sludge is possible.

Biofilm exopolysaccharides: a strong and sticky framework.
TL;DR: Wimpenny & Colasanti (1997) have suggested that biofilm structure is largely determined by the concentration of substrate, and postulated that such differences also validate at least three conceptual models of biofilms – heterogeneous mosaics, structures penetrated by water channels, and dense confluent bioFilms.
Journal ArticleDOI
Influence of loosely bound extracellular polymeric substances (EPS) on the flocculation, sedimentation and dewaterability of activated sludge.
Xiao-yan Li,Shu-fang Yang +1 more
TL;DR: Although EPS is essential to sludge floc formation, excessive EPS in the form of LB-EPS could weaken cell attachment and the floc structure, resulting in poor bioflocculation, greater cell erosion and retarded sludge-water separation.

TL;DR: This work presents a summary of PN/A technologies that have been successfully developed, implemented and optimized for high-strength ammonium wastewaters with low C:N ratios and elevated temperatures and discusses the remaining obstacles.

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.

TL;DR: A consistent and descriptive nomenclature is suggested for reactors in which the anammox process is employed, and Reactors with a high specific surface area like the granular sludge reactor employed in Rotterdam provide the highest volumetric loading rates.
