“…In general, although the influent antibiotic concentrations were lower than the large-scale WWTPs in China, they are comparable to those reported in the large-scale WWTPs of other countries (Le-Minh et al, 2010;Dolar et al, 2012). This is not surprising because two thirds of inpatients on average use antibiotics in China, which is significant higher than WHO guideline of 30% (Hu et al, 2003).…”

a b s t r a c tThe occurrence and removal of 19 antibiotics (including four macrolides, eight sulfonamides, three fluoroquinolones, three tetracyclines, and trimethoprim) were investigated in two ecological (constructed wetland (CW) and stabilization pond (SP)) and two conventional wastewater treatment processes (activated sludge (AS) and micro-power biofilm (MP)) in a county of eastern China. All target antibiotics were detected in the influent and effluent samples with detection frequencies of >90%. Clarithromycin, ofloxacin, roxithromycin and erythromycin-H 2 O were the dominant antibiotics with maximum concentrations reaching up to 6524, 5411, 964 and 957 ng/L, respectively; while the concentrations of tiamulin, sulfamerazine, sulfathiazole, sulfamethazine, sulfamethizole and sulfisoxazole were below 10 ng/L. Although the mean effluent concentrations of target antibiotics were obviously lower than the influent ones (except ciprofloxacin), their removals were usually incomplete. Principal component analysis showed that the AS and CW outperformed the MP and SP processes and the AS performed better than the CW process in terms of antibiotics removal. Both the AS and CW processes exhibited higher removal efficiencies in summer than in winter, indicating biological degradation could play an important role in antibiotics removal. Because of the incomplete removal, the total concentration of detected antibiotics increased in the mixing and downstream sections of a local river receiving the effluent from a typical wastewater treatment facility practicing AS process. Nowadays, ecological wastewater treatment processes are being rapidly planned and constructed in rural areas of China; however, the discharge of residual antibiotics to the aquatic environment may highlight a necessity for optimizing or upgrading their design and operation.

“…The removal efficiency diminished considerably for micropollutants having neutral or positive charges. For example, the removal was near 100% fornaxoprene, versus 20% for acetaminophen (neutral) and 60% for athenolol (positive) [23].…”

“…In this sense, various studies have investigated the treatment of effluents on this scale, with a growing number devoted specifically to removal of micropollutants ( Figure 1). Dolar et al [23] investigated the removal of several micropollutants by reverse osmosis after passage through a MBR and observed that all the target compounds were below the limit of quantification. Likewise, Cartagena et al [17] obtained high removal rates (>99%) of various classes of micropollutants in the permeates from NF and RO membranes.…”

Micropollutants are defined as contaminants found in trace concentrations in water bodies that are persistent and bioactive, meaning they are not completely biodegradable and cannot be removed by conventional water treatment methods. Because of these aspects, their detection and removal pose a challenge to the scientific community. Among them are endocrine disruptors, drugs, agricultural chemicals, personal grooming products, industrial additives and others. These micropollutants are the cause for global concern, because their presence in water supply systems is suspected of causing health problems in humans and animals. To develop efficient techniques to remove them, it is fundamental to understand their physico-chemical properties and the available treatment types and conditions. Membrane separation processes (MSPs) and advanced oxidation processes (AOPs) are the focus of this literature review, as potential treatment methods to remove micropollutants. The former process stands out for high rejection rates (above 90%) of various micropollutants, but it generates a concentrated secondary waste stream. In turn, the latter process can remove micropollutants without generating secondary wastes, and can also be applied and combined with other treatment methods.

“…Thus, a plethora of several different new and pioneering methods have been developed and tested as final wastewater treatment to remove these pollutants, such as activated carbon adsorption (Yu et al, 2008), ozonation and advanced oxidation processes (Kim et al, 2008), membrane filtration (Snyder et al, 2007), reverse osmosis (Lee et al, 2012;Dolar et al, 2012) and bio-filtration (Reungoat et al, 2011). Unfortunately, each of them possesses several drawbacks and/or most of them are able to eliminate only specific contaminants.…”

a b s t r a c tThis study shows the evaluation of the possible use of the freshwater bivalve Dreissena polymorpha for the removal of some recalcitrant contaminants, namely many pharmaceuticals and drugs of abuse that are not sufficiently removed from civil wastewaters. This mollusk has an enormous filtering capability and is highly resistant to natural and anthropogenic stresses and to a significant bioaccumulation of lipophilic contaminants. All these characteristics may be particularly useful for the removal of compounds not easily eliminated by conventional wastewater treatment processes. To verify this hypothesis an experimental study was conducted at the pilot scale using a pilot plant installed in the largest wastewater treatment plant of Milan (Milano-Nosedo, Italy). First, we presented results obtained in several preliminary tests in order to evaluate the capability of zebra mussel specimens to survive in different wastewater mixtures, its filtering capacity and the possible influence of bio-and photo-degradation in the abatement of the molecules of interest. Finally, data obtained in the final tests demonstrated a capacity of this filter-feeder to reduce the concentrations of several pharmaceuticals and drugs of abuse higher than that obtained by the simple natural sedimentation, suggesting a possible implementation of the bio-filtration process in wastewater management.
