The determination of fertiliser quality of the formed struvite from a WWTP

open access: yesWater Science and Technology, 2021
Struvite from nutrient-rich wastewaters has been identified as a potential substitute for commercial mineral fertilisers, with the added benefit of reducing threats to global food security by prolonging phosphate rock reserves. A fertilisation test using

Dynamic and equilibrium precipitation of struvite from the concentrated cellulosic ethanol stillage

open access: yesWater Science and Technology, 2021
The phosphate rock mineral is the main source of P-fertilizer production. It is estimated to become depleted in next century. Thus, the recovery of phosphorus from waste streams has attracted great interest.

Struvite as a Sustainable Fertilizer in Mediterranean Soils

open access: yesAgronomy, 2023
Recycled sources of phosphorus (P) and nitrogen (N), such as struvite extracted from wastewater, have the potential to substitute conventional manufactured fertilizers and mitigate environmental problems such as water eutrophication or the depletion of ...

Optimizing Struvite Crystallization at High Stirring Rates

open access: yesCrystals, 2023
Phosphorus and ammonium can both be recovered in the presence of magnesium through struvite (MgNH4PO4·6H2O) crystallization. The present work aimed to optimize struvite crystallization at turbulent solution flow.

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 ...

Peristomal struvite incrustations [PDF]

open access: yesBMJ Case Reports, 2014
A 42-year-old woman who had a urostomy formed at the age of 6 years for a neurogenic bladder due to a myelomeningocele presented to our department with painful white deposits of hard consistency on peristomal skin, suggestive of struvite incrustations after some weeks of evolution (figure 1). Figure 1 White …

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.

Precipitation Diagrams of Struvite and Dissolution Kinetics of Different Struvite Morphologies [PDF]

open access: yesCroatica Chemica Acta, 2002
Spontaneous precipitation in the systems MgCl2-H3P04-NH40H-NaCl (0.15 mol dm-3)-H20, MgS04-NH4H2P04-H20 and MgS04-NH4H2P04-NaCl (0.15 mol dm-3)-H20 was studied at 25 and 37 °C and initial pH = 4. Precipitates aged for 24 hours and 30 days were characterized by means of Chemical analyses, X-ray diffractometry, FT-IR spectroscopy and thermogravimetry ...

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.
