Reactor performances along operation. a TMP, b total COD, and c suspended COD profiles of the control reactor (R–M: membrane without potential applied) and the electromembrane reactors R-0.3 (membrane with −0.30-V potential applied) and R-0.2 (membrane with −0.20-V potential applied). (Numbers that follow the ± signs are standard deviation (SD) in this study. Error bars in (b) and (c) are from Day 1 to 5 (n = 5), from Day 13 to 17 (n = 5), from Day 24 to 28 (n = 5), and from Day 38 to 42 (n = 5). Source data are provided as a Source Data file.)
