Estrogen concentration affects its biodegradation rate in activated sludge.

Abstract:

The effect of concentration on the biodegradation rate of the steroid estrogens, estrone (E1) and 17-alpha-ethinylestradiol (EE2), was studied in batch and continuous-flow reactor systems using fresh activated sludge from two sewage treatment plants. Between the concentrations of 0.03 to 10 μg/L in the batch system no consistent difference was found in the biodegradation rates for either estrogen. The biodegradation half-life was 0.3 to 0.7 h for E1, and 1.5 to 4.4 h for EE2 at 15 to 20°C. Ho...
