Summary: In this study, a cost-efficient, environmentally friendly, and highly acidic biotrickling filter was investigated for the removal of H2S. The results showed that the removal efficiency of H2S and elimination capacity were influenced by the empty bed retention time (EBRT). The proportion of sulfate and elemental sulfur in the desulfurization products changed with the increase of EBRT. Microbial community analysis revealed that Acidithiobacillus, Thiobacillus, Sulfuricurvum, and Sulfobacillus were the dominant genera involved in the removal of H2S.

Summary: This study aims to understand the function of ClcR and CbsR, and it shows that CbsR positively regulates the transcription of cbsFAaAbAcAdB operon encoding the upstream pathway of chlorobenzene catabolism, while ClcR activates the transcription of clcABCDE operon encoding the downstream pathway.

Summary: This study investigates the fate of 20 emerging contaminants in ten municipal wastewater treatment plants. Both conventional and biological nutrient removal technologies are effective in degrading these pollutants. However, the removal of antibiotics is limited and further improvement is needed.

Summary: In this study, a combined rural sewage treatment facility based on anaerobic baffled reactor and integrated constructed wetlands was built to evaluate the removal performance, pathway, and mechanism for Ofloxacin (OFL) and conventional pollutants. The results showed that OFL and TN removal efficiency achieved 91.78% and 91.44%, respectively. Sludge adsorption was the primary removal pathway for OFL, and Proteobacteria played a crucial role in OFL removal.

Summary: The study investigated the removal of different natural organic matter components from boreal lake water in a full-scale drinking water treatment plant using granular activated carbon filters containing different commercial carbons. Results showed that coagulation-flocculation, flotation, and chlorine dioxide oxidation were effective in reducing organic matter content, while sand and GAC filtration were efficient in removing BDOC. It was concluded that complementary analyses such as LC-OCD, FEEM, and BDOC are beneficial for optimizing NOM removal in DWTPs, and comparing different GACs in full-scale studies is important due to variations in TOC removal efficiencies.

Summary: The removal of 18 bisphenols at wastewater relevant concentrations was investigated in Chlorella vulgaris cultures with pH adjusted to 6.8 and non-adjusted cultures with pH raised to above 10. Most bisphenols showed a correlation between removal and chlorophyll a concentration, indicating the crucial role of algae in their removal.

Summary: This review summarizes the removal of widely used antibiotics in constructed wetlands (CWs) and discusses the roles of substrate, macrophytes, and microorganisms in removing antibiotics. Vertical subsurface flow CWs have shown better performance in antibiotic removal. The adsorption behavior of antibiotics in wetland substrates is influenced by their physicochemical properties, substrate configuration, and operating parameters. Wetland plants can directly and indirectly affect antibiotic removal through uptake, degradation, and rhizosphere processes. Microorganisms can interact with antibiotics through biosorption, bioaccumulation, and biodegradation. Strategies for further enhancing antibiotic removal in CWs include optimizing operation parameters, innovating substrate, strengthening microbial activity, and integrating with other treatment technologies.

Summary: The combination of photocatalytic-biodegradation using polyurethane sponges modified with visible light-responsive g-C3N4 and mixed culture microbes resulted in 94% removal of ciprofloxacin. This method had a higher total organic carbon (TOC) removal rate compared to photocatalytic degradation alone. The microbial community primarily belonged to Proteobacteria, playing a major role in the efficient degradation process.

Summary: This study evaluated the removal of perfluorooctanic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) using granular activated carbon (GAC) harvested from filter-adsorbers in drinking water treatment plants. The results showed that GAC can achieve significant removal of PFOA and PFOS through adsorption. Factors such as GAC service time and empty bed contact time (EBCT) were found to affect the removal efficiency. An empirical model was proposed to predict the removal of PFOA and PFOS based on GAC service time and EBCT.

Summary: Landfill leachate treatment is challenging due to the complex chemical composition. This study identified factors associated with improved removal performance in wetland systems dosed with landfill leachate, with effluent recirculation playing a key role in adjusting composition and enhancing removal performance. Organic and nutrient removal in the hybrid wetlands primarily relied on adsorption, microbial degradation, and plant uptake, with different removal pathways affected by the imbalanced pollutant composition ratio.

Summary: The study isolated a strain, Cupriavidus oxalaticus T2, with the ability to simultaneously degrade phenol and denitrify under aerobic conditions. Strain T2 was able to effectively remove nitrate and phenol without accumulation of nitrite and ammonium, suggesting its potential application in eco-friendly wastewater treatment.
