New insights on simultaneous nitrate and phosphorus removal in pyrite-involved mixotrophic denitrification biofilter for a long-term operation: Performance change and its underlying mechanism.

Science of the Total Environment, 2022
Simultaneous nitrate and phosphorus removal can be completed by pyrite- and influent organics-involved mixotrophic denitrification and chemical phosphorus removal via iron precipitation.

Biological Phosphorus Removal Combined with Ferrous Chemical Phosphorus Removal

Advanced Materials Research, 2014
Chemical phosphorus removal is widely applied to enhance the biological phosphorus removal in order to meet the discharge requirement. Performance change caused by ferrous sulfate was investigated in this study. Compared to the control system which was not chemically dosed, pH and SVI slightly decreased while conductivity increased.

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.

Synergistic Integration of Anammox and Endogenous Denitrification Processes for the Simultaneous Carbon, Nitrogen, and Phosphorus Removal.

Environmental Science and Technology
The feasibility of a synergistic endogenous partial denitrification-phosphorus removal coupled anammox (SEPD-PR/A) system was investigated in a modified anaerobic baffled reactor (mABR) for synchronous carbon, nitrogen, and phosphorus removal.

Efficient removal of phosphorus by adsorption

Phosphorus Sulfur and Silicon and the Related Elements, 2022
The release of excessive amounts of phosphorus into water bodies causes growth of algae, eutrophication, death of fish and plants, reduction in water quality, depletion of dissolved oxygen, and other serious environmental problems.

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 ...

Effects of the carbon/nitrogen (C/N) ratio on a system coupling simultaneous nitrification and denitrification (SND) and denitrifying phosphorus removal (DPR)

Environmental technology, 2020
Simultaneous nitrification and denitrification (SND) were coupled with a denitrifying phosphorus removal (DPR) to achieve simultaneous nutrient and carbon removal. With influent chemical oxygen demand (COD), ammonia-N (NH4 +-N), and total phosphorus (TP)

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.
