Summary: Anaerobic membrane bioreactors (AnMBRs) show promising applications in treating municipal wastewater, effectively removing chemicals with strong electron-donating functional groups and highly hydrophobic compounds. Adsorption and biodegradation are key processes for TrOCs removal, and combining membrane separation technologies with bioreactor technology can enhance removal efficiency. Operating conditions play a critical role in AnMBRs performance, and addressing challenges and future perspectives can lead to wider adoption and improved TrOCs removal.

Summary: Cytostatics are a major concern in cancer therapy due to their resistance to wastewater treatment processes and potential harm to organisms. The ubiquity of cytostatics in effluents and natural water streams raises concerns about environmental integrity. Membrane processes, known for their high removal rates for organic pollutants, have potential benefits in mitigating the entrance and spread of cytostatics in the environment. This comprehensive literature review explores the application of membrane-based processes for the treatment of cytostatic-contaminated wastewaters and waters, discussing operating conditions, removal mechanisms, toxicity, and implementation from an economic and environmental perspective.

Summary: Membrane bioreactors (MBRs) combine membrane separation with biologically activated sludge to produce high-quality effluent for water reclamation. This study investigated the removal of residual pollutants from MBR effluents using ferrate (VI) and compared it with ferric chloride (FeCl3). The results showed that ferrate was more effective than FeCl3, even at a lower dosage, and had properties of oxidation, coagulation, and disinfection, which can reduce post-treatment steps and expenses for water reclamation.

Summary: Cell-based toxicity testing is a valuable tool in (eco)toxicological research, allowing ethical evaluation of contaminants on marine megafauna. However, metal interactions with dissolved ligands in the microplate environment may affect exposure concentrations. This study established and evaluated cell-based bioassays for toxicity testing of metals in dugongs, showing that chromium was the most toxic metal, followed by cadmium. The research also highlighted the importance of understanding metal partitioning in cell-based assays for accurate toxicity assessment.

Summary: Antimicrobial resistance (AMR) is a major global health threat, and current surveillance programs lack monitoring outside healthcare settings. Wastewater testing can provide a simple and continuous way to survey AMR trends in the community. By monitoring wastewater in Greater Sydney, Australia, we found regular presence of extended-spectrum beta-lactamases-producing Enterobacteriaceae (ESBL-E), and occasional presence of carbapenem-resistant Enterobacteriaceae (CRE), vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA). Our study highlights the potential of routine wastewater surveillance for understanding factors driving AMR distribution.

Summary: This study evaluates the performance of a ceramic microfiltration membrane for extracting clean water and pre-concentrating microalgae. The results show that membrane fouling is specific to each microalgae species, but can be efficiently mitigated by aeration and regular backwashing. C. vulgaris exhibited considerable membrane fouling over time, while Scenedesmus sp. showed negligible fouling. The ceramic microfiltration membrane can simultaneously enrich the microalgae solution and recycle permeated water for microalgae cultivation.

Summary: Co-culture of microalgae-activated sludge has the potential to purify wastewater while reducing energy demand from aeration. This study used a mechanically stirred membrane photobioreactor to evaluate the impact of biomass retention time on treatment performance and membrane fouling. Results showed that the highest productivity was achieved at a biomass retention time of 7 days, with a lower retention time leading to increased fouling rates. The optimum biomass retention time of 7 days allowed for sufficient access to light and nutrient exchange for mutualistic interactions between microalgae and activated sludge.

Summary: Applications of advanced oxidation processes (AOPs) in water and wastewater treatment have been of great interest. UV-chlorine (UV-Cl) is emerging as a potentially cost-effective alternative to UV/hydrogen peroxide (UV-H2O2), showing efficient degradation of emerging chemicals in contaminated water. UV-H2O2 does not have superiority over UV-Cl in terms of disinfection by-product (DBP) formation. However, more investigation and pilot-scale studies are needed to establish UV-Cl as a reliable alternative to UV-H2O2.

Summary: Limited research has been conducted on microplastics (MPs) and tire wear particles (TWPs) in stormwater. This study provides information on the abundance of MPs and TWPs in Australia and offers strategies to mitigate MP pollution. The results indicate that stormwater serves as a pathway for MPs, including TWPs, to enter aquatic habitats. Constructed wetlands and microlitter capture devices can effectively reduce the transport of MPs from stormwater to receiving waterways.

This study investigated the performance of different lightweight green wall media in removing twelve emerging contaminants from greywater. The results showed that coco coir and media mix columns achieved excellent removal of all contaminants through adsorption, with some hydrophilic contaminants also undergoing biodegradation. However, further research is needed to investigate the synergetic contribution of plants and media in removing these contaminants in long-term vegetated green wall systems.

Summary: A novel carbon quantum dots decorated C-doped alpha-Bi2O3 photocatalyst (CBO/CQDs) was synthesized and showed significantly improved contaminants removal efficiencies. CBO/CQDs exhibited much higher ceftriaxone sodium degradation rate constant (k) compared to pure alpha-Bi2O3 and C-doped alpha-Bi2O3. The synergistic effect of carbon doping, CQDs loading, and reduced particle size of CBO/CQDs enhanced the utilization of visible light and efficient separation of photogenerated carriers.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
