“…4 shows that less than 20% of carbamazepine and tris(2-chloroethyl) phosphate were removed after 10 incubation days. In agreement with previously published studies, the photodegradation, biodegradation and sorption onto sludge of these compounds in activated sludge and biologicallybased WWTPs seem to be negligible [30,31]. Although some studies have demonstrated an active plant uptake of carbamazepine by rooted plants such as cucumber and Thypa sp.…”

Henry's law constant higher than 3 10 -1 Pa m 3 mol -1 (i.e. 4-octylphenol, galaxolide, and tributyl phosphate) were removed by volatilization due to the effect of air stripping. Whereas biodegradation was relevant for removing ibuprofen and caffeine, carbamazepine and tris(2-chloroethyl) phosphate behaved as recalcitrant. The use of microalgae was proved to be relevant for increasing the biodegradation removal efficiency of ibuprofen by 40% and reducing the lag phase of caffeine by 3 days. Moreover, the enantioselective biodegradation of S-ibuprofen suggested a biotic predominant removal process, which was supported by the identification of carboxy-ibuprofen and hydroxy-ibuprofen. The results from microalgae reactors fed with nutrients showed no clear evidences of microalgae uptake of any of the studied microcontaminants.

“…Moreover, the presence of plants, producing exudates and containing microorganisms on their surfaces, aids the removal of these compounds through both biodegradation and plant uptake (Dordio et al 2010;Reinhold et al 2010). These results agree with those found by Matamoros et al (2012a) for CAFF in laboratory assays using hydroponic cultures as well as those obtained by Zhang et al (2012bZhang et al ( , 2013a in a mesocosm study planted with Scirpus sp., in which removals of[85 % were achieved. The high polarity and lack of charge at environmental pH of both ACAPh and CAFF explain their uptake by aquatic plants (Trapp 2009).…”

“…However, as stated by Andreozzi et al (2003), when some microcontaminants, such as DCF, are exposed to sunlight, they are photodegraded either by direct or indirect mechanisms, which is consistent with the higher removal efficiency observed for DCF in uncovered, light-exposed reactors. Moreover, some studies have reported the influence of sunlight radiation on the removal of DCF in natural lakes and biologically-based reclamation plants (Matamoros et al 2012a).…”

“…These biologically-based water reclamation systems are typically located after secondary wastewater units and can be almost as effective as advanced treatment systems whilst avoiding the disadvantages of advanced systems (Imfeld et al 2009;Matamoros and Salvadó 2012). A further advantage is that these systems efficiently eliminate certain pharmaceuticals (Hijosa-Valsero et al 2010;Li et al 2014;Matamoros et al 2012a).…”

The presence of pharmaceuticals and endocrine-disrupting chemicals (EDCs) in wastewater treatment plant effluents is an issue of great concern due to the negative effects that these compounds may have on human health and ecosystems. The present study aims to assess the capacity of two aquatic plants (Lemna sp. and Spirogyra sp.), commonly found in polishing ponds, for removing six pharmaceutical compounds (diclofenac, acetaminophen, ibuprofen, carbamazepine, clofibric acid, and propranolol), two EDCs (17a-ethinylestradiol and bisphenol A), and one stimulant (caffeine) under laboratory-scale conditions. Planted and unplanted reactors fed with secondary-treated wastewater or ultrapure water in both covered and uncovered conditions were studied. The highest removal efficiencies, which ranged from 31 to 100 %, were achieved in uncovered planted systems containing secondary-treated wastewater after 20 days of incubation. The results demonstrated that non-charged compounds with a log Kow between 2 and 4 were affected by the presence of vegetation, probably due to their plant uptake, whereas negatively charged compounds were not. This highlights that the presence of plants in polishing ponds plays an important role in the removal of pharmaceuticals and EDCs.

“…Biologically based wastewater treatments are considered a sustainable alternative to conventional wastewater treatment. These biologically based systems have been used for wastewater treatment in small communities and found to be effective in removing emerging contaminants (Matamoros et al 2012;Garcia-Rodríguez et al 2014). Furthermore, Garcia-Rodríguez et al (2014) mentioned that these systems can also work in combination with other conventional technologies in order to enhance removal efficiency for a low additional cost.…”

The study of low-cost techniques for the tertiary treatment of wastewater is of global interest; above all low-energy techniques that do not require the use of chemicals. In this study, a wastewater treatment technology based on the filtration by a zooplanktonic population (Daphnia magna) is studied in controlled laboratory and mesocosm experiments for different hydraulic retention times (HRT). The efficiency of the treatment is evaluated in terms of particle removal efficiency. From laboratory experiments, HRT over 12 h and Daphnia concentrations above 50 individuals l -1 guarantee a particle removal efficiency greater than 30 %. However, low HRT of 6 h would require Daphnia concentrations above 70 individuals l -1 in order to obtain a particle removal efficiency of 20 %. The minimum removal efficiency of 2 % was for HRT = 3 h, independent of the Daphnia concentration. In the mesocosm, the growth of Daphnia individuals enhanced Daphnia magna filtering rates and higher removal efficiencies than those in the laboratory for the same HRT range. In the mesocosm experiments E. coli concentrations were reduced to a maximum of 2 logarithmic units. A balance equation model is proposed to predict particle removal efficiencies for varying HRT.
