Corrigendum to ‘Anaerobic offsite Fe²⁺ releasing for electrocoagulation in ABMBR: Membrane fouling mitigation, nutrients removal and anodes protection’ [J. Water Process Eng., 39 (2021), 101706. https://doi.org/10.1016/j.jwpe.2020.101706] (Journal of Water Process Engineering (2021) 39, (S2214714420305845), (10.1016/j.jwpe.2020.101706))

The authors regret that parts of the Fig. 5 and Fig. 6 were wrongly presented. For Fig. 5, the Fig. 5e should be shown with the weight concentration of nitrogen (NH4+-N) but not NH4+; Fig 5f should be the weight concentration of phosphorus but not PO4-. The results of Fig. S4 a and Fig. S4 b in supplementary data were weight concentration of NO2- and NO3-, respectively. For Fig. 6, photos of cell 2 and cell 4 from day 101 were the same; photos of cell 1 and cell 2 from day 195 were the same, those photos were misused. The correct and final version of Figs. 5 and 6 are shown as following: [Formula presented][Formula presented]Unlabelled ImageUnlabelled Image Fig. 6 Appearance photos of the iron plate from cell 1 to cell 4 at different time periods.
