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.

Removal of Phosphorus by Hemodialysis

Seminars in Dialysis, 2015
AbstractThe control of serum phosphorus by dialysis is made difficult by the fact that intradialytic blood levels tend to be low, and because phosphorus is removed almost exclusively from the plasma during its passage through the dialyzer. The most practical way to increase phosphorus removal is to extend dialysis time, although attention to dialysis ...

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.

ENHANCED BIOLOGICAL PHOSPHORUS REMOVAL

Chemical Engineering Communications, 1998
Abstract Biological phosphorus removal is a promising alternative to the conventional chemical technologies for processing of phosphate raw materials. The object of this study was the effect of EDTA disodium on the biotreatment of tunisian phosphorite with the strain of Aspergillus niger.

Biological Phosphorus Removal Processes

2010
Enhanced biological phosphorus removal (EBPR) processes developed for wastewater treatment are mainly based on the enrichment of activated sludge with phosphorus-accumulating organisms under alternative anaerobic–aerobic conditions. According to the literature information of the EBPR processes, this chapter attempts to review the biochemical models ...

Phosphorus Removal: Field Analysis

Journal of the Environmental Engineering Division, 1981
The Great Lakes Water Quality Agreement of 1978 established by the International Joint Commission of Canada and the United States called for the achievement of 0.5 mg/\Il\N total phosphorus as the maximum effluent level in all Lake Erie and Lake Ontario municipal wastewater treatment plants discharging greater than 3785 m³/day.

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.

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 ...

Sustainable Phosphorus Removal

Filtration + Separation
Researchers from Florida Atlantic University (FAU) have discovered how to transform cyanobacterial biomass, which is typically a hazardous waste, into custom-made adsorbent materials that can pull harmful phosphorus out of water. F+S speaks to Masoud Jahandar Lashaki, assistant professor and graduate program director in FAU’s Department of Civil ...

Induction of phosphorus removal in an enhanced biological phosphorus removal bacterial population

Water Research, 1997
Abstract Volatile fatty acids (VFAs) resulting from prefermentation of influent glucose were used to cultivate a bacterial population capable of enhanced biological phosphorus removal (EBPR) in two identical anerobic/aerobic sequencing batch reactors (SBRs).
