Water quality characteristics for (A) COD, (B) TSS, and (C) E. coli in each sampling point and the post-restart event t test. The five sampling points were influent (Inf), AnMBR, permeate (Perm), post-NCS (P-NCS), and effluent (Eff). The lines in the whisker plot indicate medians, boxes 25th and 75th percentiles. A paired samples t test was used to compare measurements between the post-restart events and the normal operations water quality characteristics. “ns” = p > 0.05, “*” = p ≤ 0.05, “**” = p ≤ 0.01, “***” = p ≤ 0.001, “****” = p ≤ 0.0001.
