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.

Milky urine and struvite crystals [PDF]
Kidney International, 2015 A 66-year-old man was referred to the nephrologist because of recurrent episodes of afebrile low back pain, voiding-associated pain, and milky urine. Past history was positive for urolithiasis due to calcium oxalate stones, managed with hydrochlorothiazide 12.5 mg/day for the last 3 years.

Cow urine as a potential source for struvite production
International Journal of Recycling of Organic Waste in AgricultureBackground Rock phosphate deposits are non-renewable and are facing a decline. Due to this, phosphate fertilizers are going to be limited in future. Struvite is a crystalline mineral substance containing equimolar amount (1:1:1) of magnesium ammonium and

Location and chemical composition of microbially induced phosphorus precipitates in anaerobic and aerobic granular sludge [PDF]
, 2012 This work focuses on combined scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) applied to granular sludge used for biological treatment of high-strength wastewater effluents. Mineral precipitation is shown to occur in the core

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.
