“…Therefore, higher influent concentration of carbamazepine as used in this study is probably not the main reason of the observed higher removal in the near-anoxic (DO = 0.5 mg/L) conditions. Finally, it is interesting to note that carbamazepine removal efficiency in our previous (aerobic MBR) studies Tadkaew et al, 2011;Tadkaew et al, 2010) and in the current study (aerobic part) has been consistent and significantly higher than the most of the available reports (Abegglen et al, 2009;Clara et al, 2005). Considering the fact that in our laboratory, sludge from one MBR was used to inoculate the MBR in a subsequent study, it is possible that all three MBRs (the one in the current study and those described in Tadkaew et al, 2011;Tadkaew et al, 2010)) harbored better carbamzepine degrading (converting) microbes, which may be furthermore effective under near-anoxic (DO = 0.5 mg/L) regime.…”

“…Removals typically ranging from negligible to less than 10% in conventional MBR have been frequently reported for carbamazepine (Abegglen et al, 2009;Clara et al, 2005;Zhang et al, 2008). In this study, a rather high average removal of 68 ± 10% was observed (Figure 3 a).…”

“…A comprehensive literature review conducted by the authors revealed the absence of any clear consensus about the effect of anoxic conditions on carbamazepine removal in MBR. For instance, negligible level of removal of carbamazepine was reported by Clara et al (2005) and Abegglen et al (2009), although different configurations of MBR (sequential anoxicaerobic MBR and aerobic MBR, respectively) were utilized in those studies. However, a few recent studies have reported better removal of carbamazepine under anoxic conditions during treatment in constructed wetland (Park et al, 2009) and river bank filtration (Maeng et al, 2011).…”

This study reveals for the first time that near-anoxic conditions (dissolved oxygen, DO = 0.5 mg/L) can be a favourable operating regime for the removal of the persistent micropollutant carbamazepine by MBR treatment. The removal efficiencies of carbamazepine and sulfamethoxazole by an MBR were systematically examined and compared under near-anoxic (DO = 0.5 mg/L) and aerobic (DO > 2 mg/L) conditions. Preliminary batch tests confirmed that sulfamethoxazole is amenable to both aerobic and anoxic biotransformation. However, carbamazepine-a known persistent compound-showed degradation only under an anoxic environment. In good agreement with the batch tests, during near-anoxic operation, under a high loading of 750 µg/L.d, an exceptionally high removal (68±10%) of carbamazepine was achieved. In contrast, low removal efficiency (12±11%) of carbamazepine was observed during operation under aerobic conditions. On the other hand, an average removal efficiency of 65% of sulfamethoxazole was achieved irrespective of the DO concentrations.

“…The effect of redox conditions or dissolved oxygen on the removal of PhACs in MBR has been reported in a few studies [144][145][146]. In a study by Suarez et al [147], PhACs were classified based on their biodegradation potential under aerobic and anoxic conditions: they observed that readily degradable PhACs such as fluoxetine and ibuprofen were biodegradable under both anoxic and aerobic conditions, while a few such as roxithromycin, naproxen, diclofenac and erythromycin were persistent in anoxic conditions but highly biodegradable under aerobic conditions.…”

Carbamazepine (CBZ), a pharmaceutical compound, has been proposed as an anthropogenic marker to assess water quality due to its persistence in conventional treatment plants and widespread presence in water bodies. This paper presents a comprehensive literature review on sources and occurrences of CBZ in water bodies, as well as toxicological effects and regulations of the drug. Given the documented side effects of CBZ on the human body when taken medicinally, its careful monitoring in water is recommended. CBZ residues in drinking water may provide a pathway to embryos and infants via intrauterine exposure or breast-feeding, which may cause congenital malformations and/or neurodevelopmental problems over long term exposure. An in-depth technical assessment of the conventional and advanced treatment technologies revealed the inadequacy of the standalone technologies. Compared to conventional activated sludge and membrane bioreactor processes, effective removal of CBZ can be achieved by nanofiltration and reverse osmosis membranes. However, recent studies have revealed that harsh chemical cleaning, as required to mitigate membrane fouling, can often reduce the long-term removal efficiency. Furthermore, despite the efficient performance of activated carbon adsorption and advanced oxidation processes, a few challenges such as cost of chemicals and regeneration of activated carbon need to be carefully considered. The limitations of the individual technologies point to the advantages of combined and hybrid systems, namely, membrane bioreactor coupled with nanofiltration, adsorption or advanced oxidation process.

“…However, the liquid effluent of enhanced wastewater treatment systems still contains considerable amounts of nutrients, putting pressure on the ecology of receiving surface waters (depending on the population density and the natural cleaning capacity of the receiving water bodies) [2]. For further optimization of wastewater treatment and the elimination of the remaining nutrients, pharmaceutical and endocrine disruptors, and other micropollutants, additional treatment stages are required such as nano filtration, reverse osmosis, activated carbon absorption, and advanced oxidation processes [25,26].…”

Terra Preta Sanitation (TPS) plays a key role in sustainable sanitation (SuSan) and in the sustainable management of resources such as water, energy, soil (agriculture), liquid and solid organic waste streams as well as in the development of sustainable urban environment and infrastructure systems. This paper discusses the advantages of, and requirements for, SuSan systems, focusing on TPS. Case studies showing the stepwise extension and re-development of conventional sanitation systems (CSS) using TPS technologies and system approaches are presented and discussed. Decentralized TPS systems integrated in sustainable urban resource management were implemented in the German cities of Hamburg and Berlin. The compilation of best practice examples and findings using the newest TPS systems illustrates the immense potential of this approach for the transformation from conventional to SuSan systems. For this purpose, the potential savings of drinking water resources and the recycling potential of nutrient components are quantified. The results strongly suggest the need to encourage the development and application of innovative decentralized sanitation technologies, urban infrastructures, and resource management systems that have TP as a key component.
