Enhanced biological phosphorus removal and its modeling for the activated sludge and membrane bioreactor processes [PDF]

, 2013
A modified activated sludge process (ASP) for enhanced biological phosphorus removal (EBPR) needs to sustain stable performance for wastewater treatment to avoid eutrophication in the aquatic environment. Unfortunately, the overall efficiency of the EBPR

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.

The requirement of metal cations for enhanced biological phosphorus removal by activated sludge

, 1999
The objectives of the study described in this paper were to study the requirements of potassium, magnesium, and calcium for enhanced biological phosphorus removal (EBPR) and to determine whether either potassium or magnesium could support EBPR on its own.

Clinically Relevant Acinetobacter spp. Proliferate but Contribute Little to Phosphate Accumulation Under Enhanced Biological Phosphorus Removal-Simulating Conditions

Applied Sciences
Wastewater treatment plants (WWTPs) receive clinically relevant Acinetobacter species originating from hospitals and municipal sewage, yet their role in enhanced biological phosphorus removal (EBPR) remains unclear.

Application of contact stabilization activated sludge for enhancing biological phosphorus removal (EBPR) in domestic wastewater

HBRC Journal, 2014
AbstractThe experiment has been performed in order to investigate the effect of using contact stabilization activated sludge as an application of enhancing biological phosphorous removal (EBPR) by using contact tank as a phosphorus uptake zone and using thickening tank as a phosphorus release zone.

Inhibitory effect of copper on enhanced biological phosphorus removal

, 2010
Copper inhibition of enhanced biological phosphorus removal (EBPR) was examined in batch experiments under anaerobic and aerobic conditions. Inhibition was represented by both acetate uptake and phosphorus release coefficients under anaerobic conditions,

Re-evaluating the microbiology of the enhanced biological phosphorus removal process [PDF]

, 2019
We have critically assessed some of the dogmas in the microbiology of enhanced biological phosphorus removal (EBPR) and argue that the genus Tetrasphaera can be as important as Ca.

Biological excess phosphorus removal in activated sludge systems [PDF]

, 1988
Includes bibliographies.When this investigation was commenced in 1983 two activated sludge systems had been developed in South Africa that accomplish biological excess phosphorus (P) removal, the UCT and modified Bardenpho systems.

Phosphorus Release Dynamics from Ashes during a Soil Incubation Study: Effect of Feedstock Characteristics and Combustion Conditions

Agronomy
Recovering phosphorus (P) through combustion from waste streams, like wastewater sludge and animal manure, offers a promising solution. This research explores the P release patterns in different ashes derived from secondary raw materials, using a long ...
