Thermal decomposition of struvite [PDF]

Journal of Thermal Analysis and Calorimetry, 2004
Struvite (NH4MgPO4·6H2O) is a mineral often found in urinary tracts and kidneys. Thermal decomposition using slow low heating shows that the 'kidney' stone can be decomposed at temperatures below 40°C. At this temperature both ammonia and water are evolved. If more rapid heating is employed the decomposition occurs at around 80°C.

A better understanding of the effectiveness of placed phosphorus fertilisation with struvite for silage maize: A pot experiment

Geoderma
Struvite is emerging as a circular, slow-release phosphorus (P) fertiliser. However, its effectiveness for crops and its impact on soil P tests still remain largely unclear.

Nutrient recovery from digestates : techniques and end-products [PDF]

, 2012
In nitrate vulnerable zones application of animal manure to land is limited. Digestate from anaerobic digestion plants competes with manure for nutrient disposal on arable land, which forms a serious hinder for the biogas sector to develop in these ...

Investigating Conductivity to Predict Magnesium Addition Requirements for Struvite Precipitation in Swine Manure Slurries [PDF]

, 2009
The goal of this project was to develop a system that identified magnesium demand for struvite formation by monitoring conductivity changes during continuous injection of magnesium chloride in several swine manure slurries. The conductivity of six manure

Ion Exchange for Nutrient Recovery Coupled with Biosolids-Derived Biochar Pretreatment to Remove Micropollutants [PDF]

, 2018
Wastewater, especially anaerobic treatment effluent, contains high ammonia nitrogen (NH4-N) and inorganic orthophosphate (PO4-P), which necessitate additional treatment to meet stringent discharge regulations.

Kinetics and morphological characteristics of struvite (MgNH4PO4.6H2O) under the influence of maleic acid

Heliyon, 2020
This work reports a stirred-batch lab crystallization to examine the influence of maleic acid (HO2CCHCHCO2H), and temperatures (30 and 40 °C) on crystallization kinetics and morphology of struvite.
