a Variations in NH4+-N and PO43--P of the three AnMBRs. The anodes of the eAnMBR comprised a conductive membrane and a graphite plate, while the anodes of the eRAnMBR included a conductive membrane and a Mg plate. Applied voltage of both the eRAnMBR and eAnMBR was 0.6 V. (Note: the word electro-AnMBR means we mention both the eRAnMBR and eAnMBR). NH4+-N and PO43--P concentrations in influent were 300 mg L−1 and 160 mg L−1, respectively. b X-ray Diffraction spectra of precipitates deposited on the cathode. c Mass and purity of struvite deposited on the cathode plate during the stable period, and the elements (total numbers, mean, standard deviation, minimum, median, maximum) of this box-plot were showed in the form of a table below the figure. Source data are provided as a Source Data file.
