|[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.
