“…Like this study, Wijekoon et al (2015) observed an immediate decline in COD removal in the AnMBR right after the addition of trace organic contaminants into the influent, but the average value fully recovered after two weeks. An inhibition effect of SMX on the COD removal efficiency in the AnMBR system was also found by Wei et al (2019), with the initial SMX concentration of 10 mg/L. However, there are reports where the findings vary.…”

Sulfonamide antibiotics (SMs), as a class of antibiotics commonly used in swine industries, pose a serious threat to animal and human health. This study aims to evaluate the performance of an anaerobic membrane bioreactor (AnMBR) with and without supplying a new pomelo peel derived biochar to treat swine wastewater containing SMs. Results shows that 0.5 g/L biochar addition could increase more than 30% of sulfadiazine (SDZ) and sulfamethazine (SMZ)) removal in AnMBR. Approximately 95% of chemical oxygen demand (COD) was removed in the AnMBR at an influent organic loading rate (OLR) of 3.27 kg COD/(m 3 •d) while an average methane yield was 0.2 L/g COD removed with slightly change at a small dose 0.5 g/L biochar addition. SMs inhibited the COD removal and methane production and increased membrane fouling. The addition of biochar could reduce the membrane fouling by reducing the concentration of SMP and EPS.

“…Primary and secondary wastewater treatment processes are able to remove some ECs via sorption but often with poor efficacy (e.g., up to 28% for the NSAID diclofenac) . Meanwhile, more advanced treatment methods like anaerobic membrane bioreactors (AnMBRs) that combine the use of anaerobic digestion and membranes have seen great successes in EC removal with up to a 97% degradation rate for the antibiotic sulfamethoxazole . However, AnMBR technologies are costly to maintain and still susceptible to membrane fouling .…”

Occurrence of Emerging Contaminants in Southeast Asian Environments: Present Status, Challenges, and Future Prospects

The status of emerging contaminant (EC) profiles in Southeast Asia is currently unclear and often overshadowed by studies conducted in developed regions such as North America, Europe, and Asia. EC research in Southeast Asia is especially critical due to its high population density and poor sanitation infrastructure that introduce large amounts of ECs into the aquatic environment. This literature Review investigated the status of EC research in 11 Southeast Asian countries. Key pharmaceutical groups such as antibiotics (sulfamethoxazole, trimethoprim, sulfamethazine, ciprofloxacin, and lincomycin) and nonsteroidal anti-inflammatory drugs (NSAIDs) (diclofenac, acetaminophen, and ibuprofen) were among the most frequently studied group of ECs, while other significant groups of interests in this Review included per-and polyfluoroalkyl substances (PFAS) and phthalate esters (PAEs). With most Southeast Asian countries having agrarian economies and the onset of climate change, the overutilization of antibiotics and pesticides to meet the commercial demand for agriculture and livestock products is a major threat to aquatic environments and even human health in this region. This Review identifies understudied emerging contaminant groups in Southeast Asia such as disinfectants and transformation byproducts and recommends future research directions for Southeast Asia, particularly focusing on seasonal trends of EC input into surface and groundwater environments.

“…In this sense, biogas production has been reported to increase considerably in HRT of 36 h for pharmaceutical removal, with an average methane content of 78.5% higher than other HRTs (12, 18, 24 and 48 h) [77]. In general, the HRT applied for pharmaceutical removal in the AnMBR reactors ranged from 6 to 36 h [69,77,78].…”

Pharmaceutical residues are of environmental concern since they are found in several environmental compartments, including surface, ground and waste waters. However, the effect of pharmaceuticals on ecosystems is still under investigation. To date, the removal of these micropollutants by conventional treatment plants is generally ineffective, in addition to producing a considerable carbon footprint. In this sense, to achieve the current zero-pollution ambition, a reduction in the negative impacts of chemical substances such as pharmaceuticals on the environment must be aligned with initiatives such as the European Ecological Compact, Environment Action Programme, and Circular Economy Action Plan, among others. This review provides insight into the key drivers for changing approaches, technologies, and governance of water in Europe (Germany, Switzerland, and the UK), including improving wastewater treatment in sewage treatment plants for the removal of pharmaceuticals and their carbon footprint. In addition, an overview of emerging low-carbon technologies (e.g., constructed wetlands, anaerobic membrane bioreactors, and enzymes) for the removal of pharmaceuticals in sewage treatment works is provided. In general, the removal efficiency of pharmaceuticals could be achieved up to ca. 100% in wastewater, with the exception of highly recalcitrant pharmaceuticals such as carbamazepine (removal <60%). These technologies have the potential to help reduce the carbon footprint of wastewater treatment, which can therefore contribute to the achievement of the Europe Union’s objective of being carbon neutral by 2050.
