A SOLUBILITY AND THERMODYNAMIC STUDY OF STRUVITE

Environmental Technology, 2007
Accumulation of magnesium ammonium phosphate hexahydrate (struvite) on surfaces in contact with wastewater, especially in anaerobic sludge digestion and post-digestion processes, is a widely reported problem in the wastewater treatment industry. The solubility and thermodynamic properties of struvite at different temperatures was studied.

Dissolution of a Struvite Nephrolith in a Dog

Journal of the American Veterinary Medical Association, 1979
SUMMARY A large radiodense calculus in the left renal pelvis of a 22-month-old, male Great Dane disappeared one month following surgical removal of two struvite (magnesium ammonium phosphate) calculi from the right renal pelvis. The dog's urine likely became undersaturated with struvite for a sufficient period to permit dissolution of the renal ...

TREATMENT OPTIONS IN STRUVITE STONES

Urologic Clinics of North America, 1997
Urinary calculi have plagued man over the centuries. The epidemiology and pathogenesis of infection have been studied. The curative treatment remains problematic. Without therapy, a vicious cycle of stone formation occurs. This results in renal damage and even death. Multimodality therapy is the key.

The origin and causes of struvite stones

International Urology and Nephrology, 1991
The aim of this paper is to evaluate the possible causes of the origin of "infection stones". The main differences between the ordinary biochemical parameters of a group of patients with this type of stones was analyzed and compared with a group of oxalocalcic stone-formers and with a group of healthy subjects.

Etiopathogenesis of Canine Struvite Urolithiasis

Veterinary Clinics of North America: Small Animal Practice, 1986
Urine must be oversaturated with magnesium ammonium phosphate for struvite uroliths to form. Oversaturation of urine with magnesium ammonium phosphate may be associated with several factors, including urinary tract infections with urease-producing microbes, alkaline urine, diet, and genetic predisposition.

Struvite calculi.

Seminars in nephrology, 1997
Although calcium oxalate stones are the most common type of calculi found in the United States, struvite or infection stones are quite common and generally pose a difficult treatment dilemma. The presence of urinary infection with a urease-producing organism is necessary for these stones to form.

Struvite urolithiasis in a B6C3F1 mouse

Laboratory Animals, 1992
In a 2 year carcinogenicity bioassay using B6C3F1 mice, one male mouse developed clinical signs near termination of the study, comprising skin sores around the prepuce, penile prolapse and urine scalding. The predominant finding at necropsy was a markedly distended urinary bladder filled with numerous crystallized particles. Microscopically, there was

Struvite Precipitation by Trypanosoma cruzi

The Journal of Parasitology, 1987
It has been previously reported that some microorganisms in culture possess the capacity to generate exocellular mineral crystals. Some species of bacteria are able to produce crystals such as aragonite, calcite, apatite, stroncianite, and struvite (Greenfield, 1963, Annals of the New York Academy of Science 109: 23-45; Ennever et al., 1974, Journal of

Hoffnungsträger Struvit

agrarzeitung
Frankfurt a.M. Phosphor ist ein wichtiger Pflanzennährstoff und somit unverzichtbar für die Nahrungsmittelproduktion. Die derzeitigen Phosphorquellen sind jedoch endlich. Im Projekt „P-Net“ bewertet das Julius-Kühn-Institut (JKI) die Wirksamkeit des P-Recyclingdüngers Struvit.

The decomposition of struvite

Mineralogical Magazine and Journal of the Mineralogical Society, 1968
SummaryThe subaerial decomposition of struvite has been investigated at room temperature (21±2° C), from which it has been concluded that the decomposition product is newberyite. X-ray power patterns of newberyite, both from a diffractometer and Debye-Scherrer cameras, are given.
