Effect of a struvite dissolution diet in cats with naturally occurring struvite urolithiasis [PDF]

Journal of Feline Medicine and Surgery, 2020
Objectives The aim of the study was to determine the efficacy of the low struvite relative supersaturation diet in dissolution of feline struvite cystoliths. Methods This was a prospective, open-label, two-center study.

Agglomeration of struvite crystals

Water Research, 2007
Struvite crystallisation is widely studied as a way to remove phosphorus from wastewater effluents and simultaneously generates a valuable product for the fertiliser industry. However, to date, some crystallisation processes experimented at either pilot/or full scale face problems linked to the formation of fines.

Safety and Effectiveness of Struvite from Black Water and Urine as a Phosphorus Fertilizer [PDF]

, 2011
To ensure food supply, phosphorus must be recycled, for which an appealing method is using struvite fertilizer from human excreta. One struvite from black water and another from urine were assessed for safety under Dutch regulations, and for ...

Struvite quality assessment during electrodialytic extraction

, 2022
Struvite recovered from anaerobically digested sludge can be conducted by a two – step process. The first step consists of electrodialytic extraction of phosphorus and heavy metals from the waste.

Experimental study on the recovery of nitrogen and phosphorus from electroplating wastewater by struvite crystallization method

Gongye shui chuli
The nitrogen and phosphorus in electroplating wastewater were recovered using struvite crystallization method. The effects of pH, concentration of heavy metal ions and mass concentration of fluoride ions on the removal of nitrogen and phosphorus in ...

Impact of reactor operation on success of struvite precipitation from synthetic liquors [PDF]

, 2007
A pilot scale reactor was designed and developed to study struvite crystallisation principles. The present work focuses on the possible impact of the reactor's operating parameters on struvite characteristics, and evaluates the performances of the ...

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

Struvite stones

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.
