Effects of the Optimised pH and Molar Ratio on Struvite Precipitation in Aqueous System

MATEC Web of Conferences, 2016
Struvite (MgNH4PO4.6H2O) is one of phosphate minerals, commonly forms into aqueous solutions. It can be precipitated as mineral deposits for optimization of phosphate recovery based on the pH optimum, molar ratio and temperature levels.

Struvite Precipitation and Biological Dissolutions.

, 2010
Struvite is a salt that is formed out of  Mg2+,NH4+ and PO43- and it crystallizes in form of MgNH4PO4.6H2O. Struvite‟s (magnesium ammonium phosphate or MAP) precipitation has recently been regarded as an interesting technique to remove phosphate and ammonium from waste water. The high elimination rates and the possibility of recycling the struvite as a

Effects of Total Calcium and Iron(II) Concentrations on Heterogeneous Nucleation and Crystal Growth of Struvite

Crystals
This study investigated the effects of calcium (Ca2+) and iron (II) Fe2+ concentrations (0–500 mg/L) on the heterogeneous nucleation and crystallization behavior of struvite (MgNH4PO4·6H2O) through controlled batch precipitation experiments.

Economic evaluation of the precipitation of phosphate as struvite at pilotscale

, 2009
A novel approach using ureolytic induced MAP formation, for the recovery of phosphate, has been economically evaluated. The ureolytic MAP crystallizationon has been tested on anaerobic effluent of a potato processing company in a pilot plant, with MgCl2.6H2O as magnesium source.
