Species of phosphorus in the extracellular polymeric substances of EBPR sludge

Bioresource Technology, 2013
In this study, the species of extracellular phosphorus and their transformation during extracellular polymeric substances (EPS) extraction were explored by using (31)P nuclear magnetic resonance spectroscopy. Results show that the extraction methods had a substantial influence on the phosphorus species in the extracted EPS. Cation exchange resin method

[Influence of carbon source on EBPR metabolism and microorganism communities].

Huan jing ke xue= Huanjing kexue, 2009
A SBR was used in this study for investigating the influence of carbon source on EBPR metabolism and microorganism communities when feeding with acetate and propionate. The SBR was operated with a cycle time of 8 h and each cycle consisted of 4 min feeding, 2 h anaerobic period, 5 h aerobic period, 35 min setting, 15 min decanting and 6 min waiting ...

Denitrifying sulfur conversion-EBPR (DS-EBPR) process for treatment of seawater-based highly saline wastewater: Evaluation on performance, kinetics and microbial community structure

Bioresource Technology, 2020
DS-EBPR is an alternative to the conventional activated sludge process which face great challenge for treatment of seawater-based highly saline wastewater. This study aims to investigate the impacts of long-term (248 days) 20% and 30% seawater fractions and short-term shock of 30%, 40%, 70% and 100% seawater fractions (corresponding to 1.0, 1.4, 2.5 ...

Developments in Enhanced Biological Phosphorus Removal (EBPR)

2003
Phosphorus removal using Phosphorus Accumulating Organisms (PAOs) has attracted significant interest in recent years for controlling nutrient pollution in the aquatic environment. Enhanced Biological Phosphorus Removal (EBPR) has been known for several decades since the concept of “luxury uptake” was proposed in 1965 but the mechanisms have not been ...

EBPR for Wastewater Treatment: Teory and Praxis

2012
Wastewater polluted with high phosphorous concentration have become a serious environmental problem, mostly affecting eutrophication. Effluent phosphorous concentrations are strictly regulated in most countries. To meet this target, chemical precipitation and biological phosphorous removal are most common processes for treatment of such wastewaters ...
