Accelerating Phosphate Transport Across Membranes via Synergistic Chemical-Electrochemical Carriers. [PDF]

Angew Chem Int Ed Engl
A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...

Struvite Precipitation of Ammonia from Landfill Leachate [PDF]

, 2016
The application of struvite (magnesium ammonium phosphate,!MgNH&PO& ∙ 6H+O) precipitation and its recycling use for the purpose of ammonia removal from both synthetic solutions and landfill leachate were investigated in this study. The results demonstrated that chemical precipitation by struvite formation is efficient for ammonia removal from ...

Phosphorus recovery by struvite precipitation: a review of the impact of calcium on struvite quality [PDF]

Journal of Water, Sanitation and Hygiene for Development, 2021
Abstract Precipitation of phosphorus (P) as a struvite product from wastewater and local magnesium (Mg) sources is considered as a high economical prudent venture, as it has shown to bring down the cost of producing the product. However, there is a significant concentration of calcium (Ca) in these Mg and most wastewater sources.

Nutrient Removal and Recovery: Hazenite Precipitation From Livestock Manure Wastewater. [PDF]

Water Environ Res
This study presents an optimized precipitation process for complex livestock wastewater, achieving > 90% concurrent removal of phosphorus, magnesium, and ammoniacal nitrogen. The system successfully drives targeted Hazenite (KNaMg2(PO4)2.14H2O) crystallization, recovering essential nutrients into a high‐value, slow‐release agricultural fertilizer ...

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 ...
