Struvite precipitation by soil and fresh water bacteria
Current Microbiology, 1992Struvite precipitation by 161 bacterial strains isolated from soil and fresh water was analyzed. The results showed that the ability to form struvite is not widespread among these bacteria. Struvite precipitation was influenced by environmental factors and could be enhanced by changing the experimental conditions.

Analysis of Struvite Precipitation in Real and Synthetic Liquors
Chemical Engineering Research and Design, 2000Struvite, magnesium ammonium phosphate, is a mineral that causes a range of problems due to fouling in wastewater and sludge treatment works. Equipment susceptible to struvite encrustation includes pumps and pipework. Struvite formation was investigated at Coleshill Sludge Destruction Plant (SDP) using jar tests on real and synthetic sludge liquors.

Struvite precipitation using continuous flow reactor
AIP Conference Proceedings, 2019Due to population rapid growth, fertilizer industries have to increase the production to ensure food security causing faster non-renewable resource depletion. However, organic wastewater (cow urine) commonly contains high amount in NH4+ and PO43- is still underutilized and causing eutrophication and unpleasant odour problem.

Factors influencing urease driven struvite precipitation
Separation and Purification Technology, 2013The concern about phosphorus depletion is driving more efficient phosphorus use and recycling. In this context the precipitation of phosphate as struvite from wastewaters has recently gained considerable traction. This study investigates the influence of different parameters on the ureolytic phosphate precipitation (pH increase by means of urease ...

The behaviour of pharmaceuticals and heavy metals during struvite precipitation in urine
Water Research, 2007Separating urine from wastewater at the source reduces the costs of extensive wastewater treatment. Recovering the nutrients from urine and reusing them for agricultural purposes adds resource saving to the benefits. Phosphate can be recovered in the form of struvite (magnesium ammonium phosphate).

In this study, struvite precipitation coupled with an activated sludge process was applied to slaughterhouse wastewaters. Biological treatability characteristics of the wastewater were evaluated in a wide organic loading range of 0.06-0.42 g COD (g MLVSS)(-1)d(-1) to assess COD removal as well as the extent of nitrification.

Thermodynamics of struvite precipitation in source separated urine
2003The thermodynamics of struvite (MgNH4PO4) precipitation in source separated and artificial urine under controlled addition of magnesium chloride (MgCl2), magnesium oxide (MgO) and magnesium hydroxide (Mg(OH)2) were investigated. The solubility product of struvite in source separated and artificial urine was identified by use of experimental results in ...

Precipitation and dissolution of struvite, MgNH4PO4 x 6H2O
2001Struvit je po kemijskom sastavu MgNH4PO4ˇ6H20 i jedan je od čestih sastojaka mokraćnih kamenaca, kako u ljudi tako i u životinja. Osim toga, struvit nalazimo u sastavu naslaga kamenca u postrojenjima za obradu otpadnih voda, a pojavljuje se i u obliku prirodnog minerala.
