3.3. Impact on trace organic contaminant removal
Among the 45 TrOCs monitored (Supplementary data Table S1), 13 compounds were consistently detected in influent samples during the experimental period of four simulated hazardous events, while 13 TrOCs were detected only occasionally (Fig. 3).

The MBR achieved high removal (>90%) of significantly
