“…The concentrations found in 2011 in the influent (Table 2) were notably variable and higher than those reported in the literature for standard urban wastewaters (Hamid and Eskicioglu 2012). However, Froehner et al (2011) found average concentrations of E1, 17a-ethynyl estradiol and E2 of 1.5 lg/L in the influent of different wastewater treatment plants in Brazil and claimed that these concentration levels coincided with those found by other authors.…”

A laboratory-scale, intermittently fed, organicbased vertical flow filter was tested as a pre-treatment of high-strength urban wastewater to reduce the risk of clogging in treatment wetlands. At an average hydraulic loading rate of 815 L/m 2 day and average surface loading rates of biological oxygen demand of 458 g/m 2 day, chemical oxygen demand of 594 g/m 2 day and suspended solids of 310 g/m 2 day, the organic-based vertical flow filter achieved removal efficiencies of 48 % of biological oxygen demand, 45 % of chemical oxygen demand, 69 % of suspended solids and 51 % of turbidity. For this unit, removals were significantly correlated with organic surface loading rates but not with hydraulic loading rate. Additionally, the organic-based vertical flow filter removed almost completely the hormone residues studied: estrone, 17b-estradiol, 17b-ethynyl estradiol, diethylstilbestrol, estriol, norethisterone and testosterone, most probably by the combination of adsorption onto the organic substrate and biodegradation. The efficiency of the combined system was remarkable for biological oxygen demand (97 %), chemical oxygen demand (89 %), suspended solids and turbidity (99 %), fecal coliforms and E. coli (99.9 %) and fecal enterococci (99 %).

“…This process is observed when bacteria use their existing enzymes to degrade steroidal hormones (Hamid and Eskicioglu, 2012;Yu et al, 2013). However, the positive effect of methanol was the same in the three studied cases because its concentration was held constant (750 mg L -1 ), which was done to compare the effects of the three different media.…”

-Wastewater 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 concentrations increased and when the macro-and micronutrients were present in the solution. In the experiments with deactivated sludge, the synthetic compound EE2 was more easily removed via sorption. The bacterial communities of the activated sludge were studied, which indicated a similarity of more than 75% between the different samples. A similarity of only 50% was found between the activated and deactivated sludges.
