REMOVAL OF ESTROGENS BY ACTIVATED SLUDGE UNDER DIFFERENT CONDITIONS USING BATCH EXPERIMENTS

AbstractWastewater treatment by deactivated and activated sludge was investigated to evaluate the removal of estrogens [estrone (E1), 17β-estradiol (E2), 17α-ethinylestradiol (EE2)] via adsorption and degradation. Different treatment conditions were used, including three mixed liquor volatile suspended solid (MLVSS) concentrations, three methanol concentrations (carbon source) and three types of aqueous media (water, synthetic solution, and supernatant). The E2 was degraded the fastest by the bacterial community. In all cases the removal rate increased when the initial MLVSS and methanol con...
