Short-term effects of carbon source on the competition of polyphosphate accumulating organisms and glycogen accumulating organisms

, 2004
The effectiveness of enhanced biological phosphorus removal (ESPR) systems is directly affected by the competition of polyphosphate accumulating organisms (PAOs) and glycogen accumulating organisms (GAOs).

Quorum sensing involved in regulating biological phosphorus removal under two different addition modes of polystyrene microplastics

Chemical Engineering Journal Advances
Microplastics (MPs) impair wastewater treatment by lowering pollutant removal and accumulating in systems, yet their effects on microbial metabolic interactions remain largely unexplored. This study investigated the effects of polystyrene MPs (PS-MPs) on

Full-scale enhanced biological phosphorus removal implementation: Process performance and microbial community dynamics treating potato processing wastewater

Water Resources and Industry
Chemical phosphorus (P) precipitation has long been the default approach for treating potato-processing wastewater, effectively meeting discharge limits but requiring substantial chemical inputs, generating excess sludge and carrying significant ...

Impacts of multiwalled carbon nanotubes on nutrient removal from wastewater and bacterial community structure in activated sludge.

PLoS ONE, 2014
BackgroundThe increasing use of multiwalled carbon nanotubes (MWCNTs) will inevitably lead to the exposure of wastewater treatment facilities. However, knowledge of the impacts of MWCNTs on wastewater nutrient removal and bacterial community structure in

Incorporating microbial ecology into the metabolic modelling of polyphosphate accumulating organisms and glycogen accumulating organisms

, 2010
In the enhanced biological phosphorus removal (EBPR) process, the competition between polyphosphate accumulating organisms (PAO) and glycogen accumulating organisms (GAO) has been studied intensively in recent years by both microbiologists and engineers,

Effect of pH reduction on polyphosphate- and glycogen-accumulating organisms in enhanced biological phosphorus removal processes

, 2010
We investigated the effect of pH reduction on polyphosphate-accumulating organisms (PAOs) and glycogen-accumulating organisms (GAOs) in the enhanced biological phosphorus removal (EBPR) process. Three laboratory-scale EBPR reactors were used.

Ecophysiology of putative polyphosphate-accumulating organisms revealed by FISH-Raman

, 2022
Phosphate is a vital, but limited resource, so recycling is crucial to support the increasing demand. The enhanced biological phosphorus removal process in wastewater treatment plants can ensure recycling of phosphate from the wastewater by the use of ...

Refinement of the “Candidatus Accumulibacter” genus based on metagenomic analysis of biological nutrient removal (BNR) pilot-scale plants operated with reduced aeration

mSystems
Members of the “Candidatus Accumulibacter” genus are widely studied as key polyphosphate-accumulating organisms (PAOs) in biological nutrient removal (BNR) facilities performing enhanced biological phosphorus removal (EBPR). This diverse lineage includes
