Abstract

In complement to the initial study assessing the impact of hazardous events on membrane bioreactor (MBR) bulk performances, detailed assessment of the consequences of similar events has now been conducted on the removal of a wide range of trace organic chemical contaminants. The investigated chemicals include 12 steroidal hormones, 4 xenoestrogens, 2 pesticides, 23 pharmaceuticals and personal care products. Under salinity, DNP, ammonia and organic carbon shock conditions, overall removal of hydrophobic chemicals (log DpH7≥2.5) was not or only slightly affected. Since these chemicals are largely adsorbed to biomass, these results imply that biotransformation within the biomass structure itself was maintained. However, removal of hydrophilic chemicals (log DpH7
