Performance of a Tropical Enhanced Biological Phosphorus Removal Process at Different Carbon Loadings

Chemical Engineering Transactions, 2017
In recent years, efficient enhanced biological phosphorus removal (EBPR) processes operating at temperature higher than 28 °C have been reported in several studies. However, the operating strategy to maintain stable and high phosphorus removal efficiency

Low Acetate Concentrations Favor Polyphosphate-Accumulating Organisms over Glycogen-Accumulating Organisms in Enhanced Biological Phosphorus Removal from Wastewater

, 2016
Glycogen-accumulating organisms (GAOs) are thought to compete with polyphosphate-accumulating organisms (PAOs) in enhanced biological phosphorus removal (EBPR) wastewater treatment systems. A laboratory sequencing batch reactor (SBR) was operated for one

The effect of pH on the competition between polyphosphate-accumulating organisms and glycogen-accumulating organisms

, 2005
In enhanced biological phosphorus removal (EBPR) processes, glycogen-accumulating organisms (GAOs) may compete with polyphosphate-accumulating organisms (PAOs) for the often-limited carbon substrates, potentially resulting in disturbances to phosphorus ...

Microbial diversity and gene abundance in denitrifying bioreactors: A comparison of the woodchip surface biofilm versus the interior wood matrix

Journal of Environmental Quality, Volume 53, Issue 5, Page 565-576, September/October 2024.
Abstract Excessive amounts of nitrogen (N) and phosphorus (P) can lead to eutrophication in water sources. Woodchip bioreactors have shown success in removing N from agricultural runoff, but less is known regarding P removal. Woodchip bioreactors are subsurface basins filled with woodchips installed downgradient of agricultural land to collect and ...

Biological phosphorus removal during high-rate, low-temperature, anaerobic digestion of wastewater

Frontiers in Microbiology, 2016
We report, for the first time, extensive biologically-mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for low-temperature (12°C) anaerobic ...

Assessing the performance of polyphosphate accumulating organisms in a full‐scale side‐stream enhanced biological phosphorous removal

Water Environment Research, Volume 96, Issue 1, Page 1-148, January 2024.
A full‐scale side‐stream enhanced biological phosphorous removal (S2EBPR) was monitored to examine the correlation between polyphosphate accumulating organisms (PAOs) activity and seasonal/operational parameters, analyze the microbial community, and assess S2EBPR feasibility.

Effect of Salt on the Metabolism of ‘Candidatus Accumulibacter’ Clade I and II

Frontiers in Microbiology, 2018
Saline wastewater is known to affect the performance of phosphate-accumulating organisms (PAOs) in enhanced biological phosphorus removal (EBPR) process. However, studies comparing the effect of salinity on different PAO clades are lacking. In this study,
