Influence of Hydraulic Retention Time, Sludge Retention Time, and Ozonation on the Removal of Free and Conjugated Estrogens in Japanese Activated Sludge Treatment Plants
Original language description
This study describes the occurrence, fate, and removal of free estrogens (estrone (E1), 17 beta-estradiol (E2), estriol (E3), 17 alpha-ethynylestradiol (EE2)) and their glucuronide and sulfate conjugates (estrone-3-sulphate (E1-3S), 17 beta-estradiol-3-sulfate (E2-3S), estriol-3-sulfate (E3-3S), estrone-3-glucuronide (E1-3G), 17 beta-estradiol-3-glucuronide (E2-3G), and estriol-3-glucuronide (E3-3G)) in 12 sewage treatment plants in Japan. Glucuronide conjugates were only rarely detected in sewage influents and entirely eliminated within the treatment plants. E1 was found at 69 ng/L, E2 at 108 ng/L, E1-3S at 18 ng/L, and E2-3S at 78 ng/L in the sewage influents. The average removal efficiency for E1, E2, and sulfate conjugates was 88, 92, and 93%, respectively, following activated sludge treatment. The removal of E1 and E2 was improved with increasing the sludge retention time (SRT), with the highest removal typically found from 12 days SRT onward. The removal of sulfate conjugates was
