[en] This study examines the effects of erythromycin on activated sludge from two French urban wastewater
treatment plants (WWTPs). Wastewater spiked with 10 mg/L erythromycin inhibited the specific
evolution rate of chemical oxygen demand (COD) by 79% (standard deviation 34%) and the specific
N–NH 4 þ evolution rate by 41% (standard deviation 25%). A temporary increase in COD and tryptophan-like
fluorescence, as well as a decrease in suspended solids, were observed in reactors with wastewater
containing erythromycin. The destruction of activated sludge flocs was monitored by automated image
analysis. The effect of erythromycin on nitrification was variable depending on the sludge origin.
Erythromycin inhibited the specific nitrification rate in sludge from one WWTP, but increased the
nitrification rate at the other facility.
