Enhanced Biological Phosphorus Removal and Recovery

Water Environment Research, 2008
Activated sludge systems designed for enhanced nutrient removal are based on the principle of altering anaerobic and aerobic conditions for growth of microorganisms with a high capacity of phosphorus accumulation. Most often, filamentous bacteria constitute a component of the activated sludge microflora.

Biotransformation of phosphorus in enhanced biological phosphorus removal sludge biochar

Water Research, 2020
Biochar derived from enhanced biological phosphorus removal (EBPR) sludge could be a potential phosphorus (P) fertilizer. Soil microorganisms play a regulating role on the turnover of P in soil. When the EBPR sludge biochar is added to soil, it would inevitably interact with soil microorganisms.

Removal of Phosphorus by Peritoneal Dialysis

Peritoneal Dialysis International: Journal of the International Society for Peritoneal Dialysis, 1993
Substantial evidence exists that peritoneal dialysis, as currently practiced, cannot alone remove adequate amounts of phosphorus in well-nourished patients. Current efforts should address the possibility of developing improved nontoxic oral phosphorus binders and/or different compositions of dialysate fluid.

Simultaneous nitrogen and phosphorus removal by combined anammox and denitrifying phosphorus removal process

Journal of Chemical Technology & Biotechnology, 2017
AbstractBACKGROUNDSingle‐stage nitrogen removal using anammox and partial nitrification process (SNAP process) is a promising process to treat low C/N wastewater relying on ammonia‐oxidizing bacteria (AOB) and anaerobic ammonium oxidation (anammox) bacteria. However, excess nitrate (NO3−) in effluent is a common problem for the SNAP process.

Phosphorus Removal in Vegetated Filter Strips

Journal of Environment Quality, 2003
ABSTRACTVegetated filter strips (VFS) are used recently for removal, at or near the source, of sediment and sediment‐bound chemicals from cropland runoff. Vegetation within the flowpath increases water infiltration and decreases water turbulence, thus enhancing pollutant removal by sedimentation within filter media and infiltration through the filter ...

Study of Phosphorus Removal Efficiency in Enhanced Biological Phosphorus Removal Process

2013
An 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.

Municipal wastewater phosphorus removal by coagulation

Environmental Technology, 2010
This study investigated the chemical removal of phosphorus from wastewater by means of adsorption and precipitation. Using secondary effluent from municipal wastewater treatment plants as the model wastewater, phosphorus precipitation was tested with four commonly used metal salt coagulants, and phosphorus adsorption was explored by column experiments ...

Phosphorus Speciation and Treatment Using Enhanced Phosphorus Removal Bioretention

Environmental Science & Technology, 2013
This field research investigated the water quality performance of a traditional bioretention cell retrofitted with 5% (by mass) water treatment residual (WTR) for enhanced phosphorus removal. Results indicate that WTR incorporation into the bioretention media does not negatively influence the infiltration mechanism of the bioretention system.

Changes in phosphorus removing performance and bacterial community structure in an enhanced biological phosphorus removal reactor

Water Research, 2004
A lab-scale-enhanced biological phosphorus removal (EBPR) reactor was operated for 204 days to investigate the correlation between phosphorus removing performance and bacterial community structure. The phosphorus removing performance was good from day 1 to 92 and from day 172 to 204. However, the removal activity was in a deteriorated state from day 93

Phosphorus removal structures: A management option for legacy phosphorus

Journal of Soil and Water Conservation, 2014
P hosphorus (P) loading is considered a primary contributor to surface water eutrophication (Daroub et al. 2009). Phosphorus moves from soil to surface water as dissolved or particulate P. Particulate P is typically not 100% bioavailable, having to enter solution (through dissolution or desorption) before being available for uptake.
