Phosphorus recovery by struvite precipitation: a review of the impact of calcium on struvite quality [PDF]
Journal of Water Sanitation and Hygiene for Development, 2021 Abstract Precipitation of phosphorus (P) as a struvite product from wastewater and local magnesium (Mg) sources is considered as a high economical prudent venture, as it has shown to bring down the cost of producing the product. However, there is a significant concentration of calcium (Ca) in these Mg and most wastewater sources.

Adsorption and Precipitation of Tetracycline with Struvite
Water Environment Research, 2007The interaction of tetracycline with struvite during adsorption and precipitation processes was investigated. Tetracycline removal by adsorption was affected by solution pH, contact time, and struvite concentration. The lowest tetracycline removal (8.4%) was observed at pH 7.7, the dissociation constant (pKa2) of tetracycline.

Co-Precipitation of Cd with Struvite During Phosphorus Recovery
Chemosphere, 2023During the struvite recovery process, Cd, a hazardous metal commonly found in waste streams, can be sequestered by struvite. This study investigated the influence of Cd2+ on the precipitation of struvite. Quantitative X-ray diffraction (QXRD) results showed that the purity of struvite decreased from 99.1% to 73.6% as Cd concentration increased from 1 ...

Struvite Precipitation by Trypanosoma cruzi
The Journal of Parasitology, 1987It 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

Effect of humic substances on phosphorus removal by struvite precipitation
Chemosphere, 2015Humic substances (HS) are a major fraction of dissolved organic matters in wastewater. The effect of HS on phosphorus removal by struvite precipitation was investigated using synthetic wastewater under different initial pH values, Mg/P molar ratios and HS concentrations.

Electrochemical Precipitation of Struvite
Electrochemical and Solid-State Letters, 2006Pure struvite (magnesium ammonium phosphate hexahydrate) layers were deposited by an electrochemical method, from an aqueous solution containing phosphate, ammonium, and magnesium ions. According to interracial pH measurements, it was shown that the process is governed by a strong pH increase in the vicinity of the cathodic plate, due to the ...

Chemical Control of Struvite Precipitation
Journal of Environmental Engineering, 2003The control of struvite precipitation was investigated using a range of chemical inhibitors and chelating agents. Initial experiments investigated the mass of struvite that precipitated on jar tester impellers used to mix anaerobically digested sludge liquors. Mixing the liquors resulted in degassing of CO2 increasing the pH from below 7 to above 8. It

Struvite precipitation thermodynamics in source-separated urine
Water Research, 2007Struvite (MgNH(4)PO(4).6H(2)O) precipitation eliminates phosphate efficiently from urine, a small but highly concentrated stream in the total flux of domestic wastewater. Precipitation experiments with hydrolysed urine evaluated the solubility product of struvite. The stored and fully hydrolysed urine had an ionic strength of between 0.33 and 0.56M and

Study on precipitation of struvite and struvite-K crystal in goats during onset of urolithiasis
Research in Veterinary Science, 2010To learn more about the biomineralization process of struvite in ruminants, a seldom noticeable crystal, struvite-K, was investigated in six goats in which urolithiasis was induced by feeding a cottonseed meal and rice straw diet supplemented with MgO.

Phosphorus Recovery by Methods Beyond Struvite Precipitation
Water Environment Research, 2018Unintentional phosphate precipitation at water resource recovery facilities (WRRFs) causes operation and maintenance challenges. With global phosphorus (P) scarcity looming and receiving water eutrophication caused by excess discharges of P, intentional P recovery at WRRFs has been gaining traction. To date, struvite recovery as slow release fertilizer
