“…An air-cathode single-chamber MFC was used to recover phosphorus in the form of struvite crystal, which precipitated on the surface of the cathode electrode; however, the recovery rate of phosphorus was only 27%, accounting for a small portion of total phosphorus removal (70%-82%) [33]. Ammonia removal was examined in both single-and two-chambered MFCs, and the results suggested that nitrogen losses in the air-cathode system were mainly caused by ammonia volatilization due to elevated pH near the cathode, while nitrogen losses in the two-chambered MFC were primarily due to ammonium ion diffusion through the CEM [34].…”

“…Production of ammonia gas at the cathode from dissolved ammonium in anode solution, 25 as well as production of struvite via precipitation of the phosphorus has been shown. 26,27 The ability to transfer electrons in the reverse direction, i.e., from the cathode to microbes has also been reported, leading to the potential for bioelectrosynthesis of fuels and chemicals using biocathodes. 28 Several environmental applications have also been studied including clean-up of produced water 29 and bioremediation of pollutants.…”

“…Practically, struvite can be recovered from municipal landfill leachate [8], poultry manure wastewater [9], or urine [10]. Struvite also can be produced using microbial fuel cells [11]. Recently, struvite has been produce from fertilizer wastewater [12].…”
