The Relevance of Phosphorus and Iron Chemistry to the Recovery of Phosphorus from Wastewater: A Review

Environmental Science & Technology, 2015
The addition of iron is a convenient way for removing phosphorus from wastewater, but this is often considered to limit phosphorus recovery. Struvite precipitation is currently used to recover phosphorus, and this approach has attracted much interest. However, it requires the use of enhanced biological phosphorus removal (EBPR).

A new strategy for obtaining highly concentrated phosphorus recovery solution in biofilm phosphorus recovery process

Journal of Environmental Sciences, 2022
Recovery of phosphorus (P) from wastewater is of great significance for alleviating the shortage of P resources. At present, the P recovery process is faced with the problem of excessive organic carbon consumption when obtaining a P-concentrated recovery solution.

Phosphorus recovery from aqueous solution via a microbial electrolysis phosphorus-recovery cell

Chemosphere, 2020
The coming global phosphorus (P) crisis makes P recovery from wastewater become an inevitable choice. Hydroxyapatite (HAP) crystallization is an important approach for P recovery, but its requirements for high alkali and acid are unaffordable. Thus, a microbial electrolysis phosphorus-recovery cell (MEPRC) was developed to cut down the alkali cost via ...

Phosphorus Recovery by Liquid–Liquid Extraction

Separation Science and Technology, 2009
It is acknowledged that phosphorus removal is more crucial in comparison with nitrogen removal for preventing algae glooming and eutrophication. Chemical and biological methods are common methods for the P removal. Excessive sludge production and difficulties of recovering phosphorus are concerns in terms of sustainable waste management.

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.

Potential phosphorus recovery by struvite formation

Water Research, 2002
Formation of struvite (MgNH4PO4 x 6H2O) at sewage treatment works can cause operational problems and decrease efficiency. Struvite has a commercial value and the controlled formation and recovery of it would be beneficial. A mass balance was conducted at full scale across the whole sewage treatment plant in order to identify a stream to conduct bench ...

Phosphorus removal and recovery: state of the science and challenges

Environmental Science and Pollution Research, 2022
Phosphorus is one of the main nutrients required for all life. Phosphorus as phosphate form plays an important role in different cellular processes. Entrance of phosphorus in the environment leads to serious ecological problems including water quality problems and soil pollution. Furthermore, it may cause eutrophication as well as harmful algae blooms (

Phosphorus Removal and Recovery in Water Resource Recovery Facilities

2021
Boon and bane of phosphorus are close together, as it is on the one side essential nutrient for humans, animals, and plants, especially as an indispensable component of fertilizers to provide crop plants with it by applying on agricultural land. On the other side, ending up in water bodies, high amounts of phosphorus cause eutrophication.

Phosphorus Recovery from Wastewater

2013
Phosphate (P) fertiliser is a basis for global food production that cannot be substituted. Phosphorus rock from which P fertilisers are produced is a non‐renewable and limited resource and there is growing concern that it could become scarce at some time in the future. Wastewater is a major P sink and, during wastewater treatment, P is removed with the

Prospects for phosphorus recovery from poultry litter

Bioresource Technology, 2009
Land disposal of poultry litter is an environmental concern often associated to excess phosphorus (P) in soils and potential water pollution in regions with intense poultry production. Although poultry litter can be moved off the farm and traded as fertilizer, its transportation becomes less economical with increasing distances from the farm. Thus, new
