Characterization of and Structural Insight into Struvite-K, MgKPO4·6H2O, an Analogue of Struvite [PDF]
Inorganic Chemistry, 2020 Struvite-K (MgKPO4·6H2O) is a magnesium potassium phosphate mineral with naturally cementitious properties, which is finding increasing usage as an inorganic cement for niche applications including nuclear waste management and rapid road repair. Struvite-K is also of interest in sustainable phosphate recovery from wastewater and, as such, a detailed ...

Biochar seeding properties affect struvite crystallization for soil application
Soil & Environmental Health, 2023 Struvite crystallization is a viable approach for recovering phosphorus from phosphorus-rich solutions such as urine and wastewater. However, designing seed materials to promote crystal growth and enhance the efficiency of struvite crystallization ...

Total Value of Phosphorus Recovery [PDF]
, 2016 Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication.

In Vitro Study on the Influence of Proline on Struvite Crystals
Hittite Journal of Science and Engineering, 2020 This study investigated the effect of amino acid proline, as crystal modifier, on the struvite crystallization in vitro conditions. The struvite crystals were evaluated experimentally through XRD, SEM, and FTIR to determine the structure, morphology, and

Kidney International, 1978 Struvite, a crystalline substance first identified in the 18th century, is composed of magnesium ammonium phosphate (MgNH4PO4 · 6H2O). Ulex, a Swedish geologist, is generally credited with introduction of the term struvite in 1845; he coined the geological expression “struvite” in honor of H. C. G.

Struvite-(K), KMgPO46H2O, the potassium equivalent of struvite a new mineral
European Journal of Mineralogy, 2008 The new mineral struvite-(K) is the natural potassium equivalent to struvite NH4MgPO4·6H2O. It was discovered independently at two different localities: (1) at the famous sulphosalt locality Lengenbach in Binntal, Switzerland, where it occurs in a dolomitic rock of Triassic age, in close association with various Pb-As-sulphosalts (mainly rathite).

Electrochemically induced precipitation enables fresh urine stabilization and facilitates source separation [PDF]
, 2020 Source separation of urine can enable nutrient recycling, facilitate wastewater management, and conserve water. Without stabilization of the urine, urea is quickly hydrolyzed into ammonia and (bi)carbonate, causing nutrient loss, clogging of collection ...
