Phosphate removal in agro-industry: pilot- and full-scale operational considerations of struvite crystallization [PDF]

open access: yes, 2009
Pilot-scale struvite crystallisation tests using anaerobic effluent from potato processing industries were performed at three different plants. Two plants (P1 & P2) showed high phosphate removal efficiencies, 89 + 3% and 75 + 8%, resulting in final ...

Temperature impact assessment on struvite solubility product: a thermodynamic modeling approach [PDF]

open access: yes, 2011
This work addresses the problem of phosphorus recovery from wastewater by struvite precipitation, which is chemically known as magnesium ammonium phosphate hexahydrate MgNH4PO4·6H2O.

Struvite (MgNH4PO4.6H2O) solubility and its application to a piggery effluent problem [PDF]

open access: yes, 1991
Struvite (MgNH4P04• 6H20) solution chemistry was studied in order to understand a struvite scaling problem which exists in the pipe network of a series of 4 effluent lagoons at a piggery.

Safety and Effectiveness of Struvite from Black Water and Urine as a Phosphorus Fertilizer [PDF]

open access: yes, 2011
To ensure food supply, phosphorus must be recycled, for which an appealing method is using struvite fertilizer from human excreta. One struvite from black water and another from urine were assessed for safety under Dutch regulations, and for ...

Optimization of struvite precipitation in synthetic biologically treated swine wastewater - Determination of the optimal process parameters [PDF]

open access: yes, 2013
A sustainable way to recover phosphorus (P) in swine wastewater involves a preliminary step of P dissolution followed by the separation of particulate organic matter.

Biologically induced phosphorus precipitation in aerobic granular sludge process [PDF]

open access: yes, 2011
Aerobic granular sludge is a promising process for nutrient removal in wastewater treatment. In this work, for the first time, biologically induced precipitation of phosphorus as hydroxyl-apatite (Ca5(PO4)3(OH)) in the core of granules is demonstrated by

Simultaneous ammonium and phosphate recovery and stabilization from urban sewage sludge anaerobic digestates using reactive sorbents [PDF]

open access: yes, 2018
The use of low-cost inorganic sorbents as a new sustainable strategy to enhance the valorization of nutrients (N-P-K), from the urban water cycle (e.g., side streams from sewage sludge anaerobic digestion), in agriculture applications is presented.

Investigation of struvite crystals formed in palm oil mill effluent anaerobic digester

open access: yesHeliyon, 2021
The formation of struvite crystals or magnesium ammonium phosphate (MgNH4PO4) in palm oil mill effluent (POME) occurs as early as in the secondary stage of POME treatment system.

Fate and Impacts of Triclosan, Sulfamethoxazole, and 17β-estradiol during Nutrient Recovery via ion Exchange and Struvite Precipitation [PDF]

open access: yes, 2017
Increasing emphasis on resource recovery from wastewater highlights the importance of capturing valuable products, e.g., nutrients such as nitrogen and phosphorus, while removing contaminants, e.g., organic micropollutants. The objective of this research
