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.

Tuning the morphology and adsorption capacity of Al-MIL-101 analogues with Fe3+ for phosphorus removal from water.

Journal of Colloid and Interface Science, 2020
In this work, water-stable Al-MIL-101 analogues were successfully synthesized by adjusting the Fe/Al ratio to obtain excellent phosphorus removal efficiencies.

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

Simultaneous nitrogen and phosphorus removal in the sulfur cycle-associated Enhanced Biological Phosphorus Removal (EBPR) process

Water Research, 2014
Hong Kong has practiced seawater toilet flushing since 1958, saving 750,000 m(3) of freshwater every day. A high sulfate-to-COD ratio (>1.25 mg SO4(2-)/mg COD) in the saline sewage resulting from this practice has enabled us to develop the Sulfate reduction, Autotrophic denitrification and Nitrification Integrated (SANI(®)) process with minimal sludge ...

Phosphorus removal from wastewater by mineral apatite

Water Research, 2006
Natural apatite has emerged as potentially effective for phosphorus (P) removal from wastewater. The retention capacity of apatite is attributed to a lower activation energy barrier required to form hydroxyapatite (HAP) by crystallization. The aim of our study was to test the P removal potential of four apatites found in North America.

Iron scraps enhance simultaneous nitrogen and phosphorus removal in subsurface flow constructed wetlands.

Journal of Hazardous Materials, 2020
In rural domestic wastewater treatment using subsurface constructed wetland system (SFCWs), the lack of a carbon source for denitrification and limited phosphorus uptake are responsible for low removal of nitrogen and phosphorus, and a suitable substrate

A Dynamic Physicochemical Model for Chemical Phosphorus Removal

Proceedings of the Water Environment Federation, 2013
A dynamic physico-chemical model for chemical phosphorus removal in wastewater is presented as a tool to optimize chemical dosing simultaneously while ensuring compliant effluent phosphorus concentration. This new model predicts the kinetic and stoichiometric variable processes of precipitation of hydrous ferric oxides (HFO), phosphates adsorption and ...

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.

Bioenergy generation and simultaneous nitrate and phosphorus removal in a pyrite-based constructed wetland-microbial fuel cell.

Bioresource Technology, 2019
This study investigates the performance of a pyrite-based constructed wetland-microbial fuel cell (PCW-MFC) in chemical oxygen demand (COD), nitrate (NO3--N), total inorganic nitrogen (TIN), and total phosphorus (TP) removal and bioelectricity generation,
