STRUVITE: Results about struvite precipitation
, 2023 STRUVITE OG designed and implemented a prototype, at farm-scale system, for nitrogen and phosphorus recovering from agro-livestock digestate to promote the relocation of nutrients surplus from high livestock areas to areas instead characterized by chemical fertilizer demand.

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

Precipitation of struvite using MgSO4 solution prepared from sidestream dolomite or fly ash
Heliyon, 2022 Struvite (NH4MgPO4∗6H2O) is a slow-release fertilizer produced from phosphorus and nitrogen-containing wastewater in the presence of Mg salts. Commercial Mg salts are the single most significant cost of struvite precipitation. In this study, H2SO4 formed
