Biomass fermentation to augment biological phosphorus removal
Chemosphere, 2010A combination of a lab scale biological phosphorus removal sequencing batch reactor (called mother reactor) and a side-stream biomass fermenter was setup. It was found that when fermented biomass was recirculated back into the mother reactor as volatile fatty acid (VFA) supplement, the phosphate concentration in the effluent decreased from 6 in the ...

A Biological Phosphorus Removal Potential Test for Wastewaters
Water Environment Research, 2001A simple test was proposed to assess whether phosphorus in a wastewater can be removed using a biological phosphorus removal (BPR) process. The test includes the measurement of phosphorus release during 2 hours of the anaerobic stage in a batch reactor containing phosphorus‐accumulating organisms (PAOs) and estimation of the effluent phosphorus ...

Phosphorus-accumulating organisms are considered to be the key microorganisms in the enhanced biological phosphorus removal (EBPR) process. A large amount of phosphorus is found in the extracellular polymeric substances (EPS) matrix of these microorganisms. However, the roles of EPS in phosphorus removal have not been fully understood.

Study of Phosphorus Removal Efficiency in Enhanced Biological Phosphorus Removal Process
2013An enhanced biological phosphorus removal (EBPR) system was developed in sequencing batch reactor (SBR) using acetate as the carbon source. The SBR was operated for over 2 months. Excellent phosphorus removal performance and stability were maintained in this system, where the phosphorous concentration in the effluent was below 0.6 mg/L.

Biological Phosphorus Removal, Its Role in Phosphorus Recycling
Environmental Technology, 1999At present the main types of phosphorus removal from wastewater effluents are chemical precipitation using alum or lime and biological removal. These methods of removal do not recycle phosphorus as a truly sustainable product because it is removed along with various other waste products.

An Evaluation of Biological Phosphorus Removal
1985Biological phosphorus removal (BPR) was examined to determine its feasibility as a phosphorous removal method for municipal wastewater. A literature search was conducted which reviewed previous research of the mechanism of phosphorus removal and the major biological phosphorus removal processes.

AbstractAn anaerobic/aerobic sequencing batch reactor was used to test enhanced biological phosphorus removal (EBPR) in wastewater. In the present study, after 6 weeks of operation, the phosphorous and TOC removal efficiency reached to 97.8 and 97.5%, respectively.

Rethinking the Mechanisms of Biological Phosphorus Removal
Water Environment Research, 2017ABSTRACT: Enhanced biological phosphorus removal (EBPR) was observed in high‐rate, non‐nitrifying plants in the United States that were operated in a plug‐flow mode. In facilities designed for nitrification and denitrification, a first‐stage anaerobic zone, free of nitrate and nitrite was needed to accomplish EBPR, and this is referred to as the ...

Plants for Biological Phosphorus Removal
1997Phosphorus stimulates plant growth (eutrophication) in streams, lakes, rivers, and in the ocean. A large part of the phosphorus which is discharged into the receiving waters derives from wastewater. Due to increasing eutrophication problems all over the world, the demand for phosphorus removal from wastewater is increasing.

Polyphosphate-Accumulating Bacteria and Enhanced Biological Phosphorus Removal
1999More than 50 years ago, Jeener and Brachet (1944) observed that addition of inorganic phosphate (Pi) to a suspension of yeast cells previously subjected to phosphate starvation induced massive accumulation of a basophilic substance within the cells. Soon afterwards this substance was isolated and identified as inorganic polyphosphate (polyP) (Schmidt ...
