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.

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 ...

A/O Phosphorus Removal Biotechnology

2010
Biological treatment systems accomplish phosphorus removal by using phosphorus for biomass synthesis during biochemical oxygen demand (BOD) removal. Phosphorus is an important element in microorganisms for energy transfer and for such cell components as phospholipids, nucleotides, and nucleic acids.

Biological Phosphorus Removal, Its Role in Phosphorus Recycling

Environmental Technology, 1999
At 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.

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 ...

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 ...

Effect of Water Hardness on Phosphorus Removal in the Enhanced Biological Phosphorus Removal Process: Phosphorus Transformation and Microbial Mechanisms

Water hardness is a critical yet often overlooked parameter in enhanced biological phosphorus removal (EBPR). While divalent cations are known to influence chemical phosphorus removal, their impact on biological processes—especially microbial phosphorus transformation and feedback mechanisms—remains unclear. Therefore, four anaerobic/aerobic/anoxic(A/O/
