Biological degradation of natural estrogens was investigated by separately spiking 17β-estradiol (E2) and estrone (E1) into activated sludge reactors operated in a semi-continuous flow mode under aerobic conditions. By conducting runs for simultaneous addition of glucose over the designated initial concentrations of 0, 10, 30, 50 and 100mgl −1 , respectively, the likely effect of the easily...
As the first systematic study dealing with the adsorption of estrogens by granular activated carbon (GAC), the removal behavior of 17β-estradiol (E2) and its biotransformation product of estrone (E1) in fixed GAC columns was examined using four biological activated carbon (BAC) columns (BAC-1∼BAC-4) generated by coating four GAC columns with detached microorganisms from the riverbed sediment of a...
