“…Struvite recovery from waste streams comes with technical difficulties associated with both water chemistry and the nature of the recovered solid product. For example, Ca interferes with struvite precipitation, and in many cases, livestock wastewater is high in Ca (Zhang et al, 2010; Tao et al, 2016). The use of different seed materials may lead to varying P recovery efficiency (Kataki et al, 2016), and contamination from the livestock waste stream may also be the source of substantial variation in the recovered materials (Massey et al, 2010).…”

Phosphorus recovery from wastewater as struvite (MgNH4PO4⋅6H2O) or dittmarite (MgNH4PO4⋅H2O) can decrease water pollution risk, as well as produce a P‐rich material suitable as fertilizer. However, most studies to date have focused on the removal of P from wastewater, rather than on characterization of the recovered P materials. The objective of this work was to apply microfocused X‐ray fluorescence (XRF) spectroscopy, and both bulk and microfused X‐ray absorption near edge structure (XANES) spectroscopy, to provide insight into the speciation of recovered P in various struvite‐containing and struvite‐like materials. Three materials were investigated: homogeneous crystalline struvite on apatite seed, homogeneous dittmarite, and heterogeneous struvite with sand contamination (referred to as the “sandy” material). The struvite materials were recovered from dairy wastewater, whereas the dittmarite was from a cheese processing plant. Phosphorus speciation in the crystalline struvite on apatite seed material was ∼17% apatite and 83% struvite; in the “sandy” material, P was ∼24% apatite and ∼76% struvite, with an uncertainty of approximately ±15%. The P K‐edge XANES spectra of recovered dittmarite appeared pure. These findings highlight the heterogeneity of recovered P materials and underscore the importance of P speciation to understand P release behavior and bioavailability from recovered phosphates. Core Ideas Multiple methods should be used to corroborate spectroscopic estimates of P speciation. Dittmarite P K‐edge XANES spectra are distinct from spectra of chemically similar struvite. Phosphorus K‐edge XANES spectroscopy can quantify Mg‐associated P >15 atom% P.

“…Struvite is basically an ammonium magnesium phosphate hexahydrate (NH 4 MgPO 4 .6H 2 O) (Moed et al, 2015) that has a distinctive orthorhombic crystal structure (Doyle and Parsons, 2002). The struvite formed in the wastewater from anaerobically digested dairy manure presents itself in a commonly found pyramidal form ( Figure 1) as examined by the scanning electron microscopy (SEM) (Tao et al, 2016). In groundwater reservoir facilities and desalination plants, crystal deposits found are called limestones (Ruelo et al, 2013), which mainly consist of calcium carbonate (CaCO 3 ) with iron (Fe), silicon (Si), sodium (Na), chlorine (Cl) and sulphur (S) as other constituents.…”

The palm oil mill effluent (POME) treatment process is exposed to the formation of crystal-like deposits where their accumulation could create a significant threat to achieving an efficient POME treatment. This article reviewed similar occurrences in other industries, discussed factors influencing the crystal formation and suggested possible solutions to be applied in the oil palm industry. From the review, it was found that crystal deposits have always been a nuisance and sometimes a significant threat to similar industries such as industrial, agricultural and municipal wastewater treatment facilities. Other industries where there is a handling process of certain type of fluids such as heat transfer and oil reservoir drilling fluids also faces similar problems. The article also presented the spectrum of methods for mitigation and removal of the crystal formed. For many cases, nutrient recovery through struvite precipitation has become attractive as it not only reduces crystal growth but at the same time prevents excessive nutrients discharge to the environment. Further exploitation of the recovered struvite as a fertiliser source could possibly generate additional income to the oil palm industry.

“…Struvite crystallization has also been investigated as a means for recovery of phosphorus, which can prevent eutrophication of surface waters and also provide a valuable fertilizer resource. Concern over P recovery is increasing because of its agricultural and industrial importance and the accelerating depletion of natural resources (Tao et al ., ). The use of struvite as a plant fertilizer could improve nutrient acquisition, mitigate the loss of a potential P resource, and support plant productivity in a sustainable manner (Zhang et al ., ; Li et al ., ).…”

Summary Struvite (magnesium ammonium phosphate‐MgNH4PO4·6H2O), which can extensively crystallize in wastewater treatments, is a potential source of N and P as fertilizer, as well as a means of P conservation. However, little is known of microbial interactions with struvite which would result in element release. In this work, the geoactive fungus Aspergillus niger was investigated for struvite transformation on solid and in liquid media. Aspergillus niger was capable of solubilizing natural (fragments and powder) and synthetic struvite when incorporated into solid medium, with accompanying acidification of the media, and extensive precipitation of magnesium oxalate dihydrate (glushinskite, Mg(C2O4).2H2O) occurring under growing colonies. In liquid media, A. niger was able to solubilize natural and synthetic struvite releasing mobile phosphate (PO43−) and magnesium (Mg2+), the latter reacting with excreted oxalate resulting in precipitation of magnesium oxalate dihydrate which also accumulated within the mycelial pellets. Struvite was also found to influence the morphology of A. niger mycelial pellets. These findings contribute further understanding of struvite solubilization, element release and secondary oxalate formation, relevant to the biogeochemical cycling of phosphate minerals, and further directions utilizing these mechanisms in environmental biotechnologies such as element biorecovery and biofertilizer applications.
