“…In the previous research, the authors reported that when the wastewater containing P, Mg, and NH 4 was treated in the MFC, struvite crystal deposited on the cathode, and when the wasterwater containing P and Mg but not NH 4 was treated, cattiite crystal deposited on the cathode [10]. The greater elution of P and Mg than any other inorganic mineral elements from the cathode in this research suggests that the compound containing P and Mg indeed deposited on the cathode.…”

“…The reactor was provided with the synthetic wastewater, containing sodium acetate as a substrate, a 100 mM phosphate buffer solution (NaH 2 PO 4 : 36 mM, Na 2 HPO 4 : 64 mM, NH 4 Cl: 12 mM, KCl: 3.5 mM, pH 6.8, electrical conductivity 11.2 mS/cm), minerals and vitamins described in previous publication [10]. The reactor was operated at room temperature.…”

“…Some adhering substances on the cathode were also thought to be responsible, but the removal of the substances could not restore the performance of the cathode to the extent close to that of the initial stage of operation in the previous studies. It is suspected that the incomplete restoration of theIt was reported previously that the treatment of the wastewater containing phosphorus (P), magnesium (Mg) and ammonium (NH 4 ) by MFCs led to the deposition of struvite crystal on the cathode [10]. Furthermore, the treatment of the wastewater containing P, Mg, but not NH 4 led to the deposition of cattiite, a type of magnesium phosphate.…”

Microbial fuel cells were operated with synthetic wastewater containing phosphate as a buffer and sodium acetate as a substrate. Linear sweep voltammetry showed the deterioration in the performance of the cathodes after operation (18-31% decrease of current density at 0.1V vs. Ag/AgCl). The immersion of the deteriorated cathodes in Milli-Q water and acidic and basic buffer solution improved the performance. The treatment with the acidic buffer solution restored the performance of the cathode to the extent almost equivalent to that of the cathode before operation (98-107% of current density at 0.1V vs. Ag/AgCl), whereas the treatment with Milli-Q water and the basic buffer solution did not restore the performance to that extent (92% of current density at 0.1V vs. Ag/AgCl). The improved performance by the immersion in Milli-Q water or the acidic buffer solution indicates that the water-soluble components are responsible for the deterioration in the cathode performance. Almost complete recovery of the performance in acidic condition suggests that salts that are highly soluble in acidic condition and poorly soluble in basic condition are responsible for the deterioration. The analysis of the eluted substances in the immersion solution suggests that these salts contained phosphorus, magnesium and calcium in a high concentration.

“…Limitations include the use of precious metals like platinum, issues with performance of the cathode which deteriorates when struvite particles accumulate on its surface and formation of microbial biofilms which block active sites and inhibit mass transfer, thus limiting struvite precipitation and necessitating addition of cleaning and scrubbing stages to the process (Hirooka and Ichihashi, 2013;Cusick et al, 2014).…”

Phosphorus recovery as struvite from farm, municipal and industrial waste: Feedstock suitability, methods and pre-treatments

et al. 2016

View full text Add to dashboard Cite

Global population growth requires intensification of agriculture, for which a sustainable supply of phosphorus (P) is essential. Since natural P reserves are diminishing, recovering P from wastes and residues is an increasingly attractive prospect, particularly as technical and economic potential in the area is growing. In addition to providing phosphorus for agricultural use, stripping P from waste residues and effluents lessens their nutrient loading prior to disposal. This paper critically reviews published methods for P recovery from waste streams (municipal, farm and industrial) with emphasis on struvite (MgNH 4 PO 4 6H 2 O) crystallization, including pretreatments to maximize recovery. Based on compositional parameters of a range of wastes, a Feedstock Suitability Index (FSI) was developed as a guide to inform *Manuscript Click here to view linked References researchers and operators of the relative potential for struivite production from each waste.

“…Formation of granules allows an optimal sludge recovery after clarification, but these granules are sensitive to free ammonia (Zou et al, 2015). Besides classical EBPR, very innovative P recovery devices can be considered on the basis of bio-electricity generating reactors (Hirooka and Ichihashi, 2013). Indeed, microbial fuel cells (MFC) allows P removal through chemical precipitation (around 80%) and microbial uptake (between 4% and 17%) (Tao et al, 2014).…”
