The solubility of struvite

Temperature impact assessment on struvite solubility product: A thermodynamic modeling approach

“…Fig. 6 shows a minimum value of pK sp at 30 • C for this work: Bhuiyan et al [37] and Bavic-Ivancic et al [38] also confirm this minimum value, contrary to Aage et al [20] and Burns and Finlayson [17]. It should be pointed out that the gap between our work and Bhuiyan et al [37] increases when temperature decreases.…”

“…Aage et al [20] determined the struvite solubility product with a radiochemical method at various temperatures. Burns and Finlayson [17] used pH and concentration measurements to investigate the influence of temperature on the solubility product of struvite.…”

Phosphate recovery through struvite precipitation by CO2 removal: Effect of magnesium, phosphate and ammonium concentrations

“…It was shown that the yield of struvite decreased upon increasing solution temperature from 25 to 60 • C [25]. All experiments were done at 25 • C. A series of experiments was done for the investigation of the effect of magnesium concentration in the supersaturated solutions on the precipitation of struvite.…”

Struvite precipitation for ammonium removal from anaerobically treated effluents

“…Very few studies have addressed the influence of temperature on struvite precipitation. Aage et al [40] and Ronteltap et al [12] observed a steady increase in the solubility of struvite with increasing temperature. However, no differences in the residual NH 4 + concentration were observed for effluent D1 at 4, Large amounts of suspended solids can inhibit struvite formation.…”
