“…7 Therefore, there is an increasing emphasis on efficiently recovering P from viable sources. [8][9][10][11] Landfill leachate, industrial wastewater, agricultural wastewater and slaughterhouse wastewater are some sources rich in nutrients such as N and P. 12 These waste streams can become highly contaminated from fertilizer runoff, livestock discharge and the decomposition of organic solid waste. Hence, treating them to reduce their environmental impact is essential.…”

BackgroundMicrobial fuel cell, a potential cost‐effective technology for the energy neutral treatment of wastewater. However, the successful implementation of this technology in resource recovery is still limited. In this study, a microbial electrochemical cell was designed and operated for 30 days. The critical factors assessed for removal and recovery of N and P as struvite from wastewater.ResultsThe optimization studies on critical factors like the chemical oxygen demand of wastewater (500–2000 mg/L) and cathode aeration rate (45–135 mL/min) were conducted using the pure culture of Escherichia coli. The system yielded an average power densityof 465 mW/m2, average current density of 915 mA/m2 and P recovery at an extent of 40% as struvite. Additionally the maximum reduction in the COD of 90% with an average coulombic efficiency of about 82% was obtained at a short interval of 30 days. The solubility studies of the recovered struvite for 12 h. at different pH from 4.5 to 9 showed maximum solubility of 80% at 4.5 and minimum of 3.5% at 9.ConclusionThis study moves one step closer to applying MFC technology for N and P‐rich wastewater treatment with concurrent struvite precipitation and electricity production. In this way, Sustainable Development Goals 2, 6, and 7 can be achieved through resource recovery, clean water, and bioenergy.This article is protected by copyright. All rights reserved.
