Summary: This study critically reviewed the occurrence and removal of 17 alpha-ethynylestradiol (EE2) in municipal wastewater treatment plants (WWTPs). The results showed that the concentration of EE2 in municipal wastewater was generally higher than the reported lowest-observed-effect concentration, indicating an urgent need for EE2 removal in WWTPs.

Summary: This study investigated the removal of tetracycline (TC) in three parallel lab-scale nitrification MBRs with different ammonium loading rates (ALRs) at four different concentrations. The results showed that high TC removal efficiency (90.46%) was achieved in the MBR with the highest ALR (AN1000) at an influent TC concentration of 50 mg/L. Higher ALRs promoted TC removal at lower influent TC concentrations, while no significant difference was observed at higher influent TC concentrations, suggesting that heterotrophic degradation could be strengthened after long-term exposure to high TC concentration.

Summary: This study investigated the treatment of Ethinyl Estradiol (EE2) in swine wastewater using an Upstream Solids Reactor (USR), and proposed a new method for bio-feeding regulation to enhance the anaerobic biodegradation process. The addition of propionic acid was found to be more effective in enhancing the removal of EE2 compared to lactic acid. However, controlling the pH at extreme values hindered the fermentation process and negatively affected EE2 removal. The study provides insights into the anaerobic biodegradation of EE2 and suggests a new strategy for the bioremediation of refractory pollutants.

Summary: In this study, a membrane bioreactor (MBR) was used to separate extracellular free organic carbon (EFOC) during the culture of nitrifying bacteria in activated sludge, and it was found that MBR better enriches and cultures nitrifying bacteria compared to a sequencing batch reactor (SBR). The removal rate of NH4+-N and the nitrification rate by nitrifying bacteria in the MBR were significantly higher than in the SBR. The abundance of Nitrospira in the MBR was also much greater than in the SBR. The timely removal of EFOC by the MBR was identified as an important factor in promoting the growth of autotrophic nitrifying bacteria.

Summary: In order to reduce the hazard of sulfamethoxazole (SMX) to the water ecology, the removal mechanism of SMX in wastewater was revealed. The evaluation of PVDF/DA modified membrane in the membrane bioreactor (MBR) showed good removal ability for SMX after certain acclimation. The PVDF/DA membrane could alleviate membrane fouling, improve the service life of the membrane, and reduce its operating cost.

Summary: The role of sorption and biodegradation in a membrane aerated biofilm reactor (MABR) was investigated for the removal of 10 organic micropollutants (OMPs). It was found that biodegradation dominated the removal of selected OMPs at all biofilm stages, and the removal rate increased with the increase of biofilm thickness.

Summary: Overconsumption of pharmaceuticals is causing negative impacts on human and wildlife endocrine systems. Previous studies have investigated the occurrence and fate of pharmaceuticals in municipal wastewater treatment plants (WWTPs), but the understanding of their removal mechanism in both liquid and solid phases is limited. This study assessed pharmaceuticals in both liquid and solid phases in three municipal WWTPs with different treatment configurations, providing valuable information for the evaluation of the fate of pharmaceuticals in biological processes of WWTPs.

Summary: Sulfisoxazole (SIZ), a common antimicrobial, was found in surface water and groundwater along with nitrate. The interactions between SIZ biotransformation and nitrate removal were studied in a H2-based membrane biofilm reactor (H2-MBfR). SIZ did not affect denitrification in the H2-MBfR at low input concentrations, but its removal was inhibited by nitrate. Hydrogenation reactions were responsible for the formation of transformation products. Sulfate-reducing bacteria (SRB) played a role in SIZ biotransformation, possibly utilizing SIZ as an electron donor or acceptor. The H2-MBfR showed potential for treating nitrate and SIZ-polluted wastewaters due to concurrent SIZ removal and stable denitrification.

Summary: Wastewater treatment plants play a crucial role in preventing the discharge of emerging contaminants into the environment. However, the removal mechanisms of these contaminants are still not well understood. This study investigated the effects of operational parameters on the sorption and biodegradation of contaminants of emerging concern (CECs) in activated sludge biological treatment.The developed models successfully described the dynamic behavior of a large-scale WWTP and showed significant uncertainty reduction compared to traditional modeling approaches. The models also highlighted the importance of operational parameters in CECs removal, but no globally optimum conditions for CECs removal exist. These models could aid in the improved assessment and management of CEC fate and removal in WWTPs.

Summary: The presence of antibiotics in surface waters poses a threat to human and environmental health due to the potential development of antibiotic resistance. This study aimed to analyze the literature on the photolysis, sorption, and biodegradation of selected antibiotic compounds. The results showed that information is available for predicting the rates of direct and indirect photolysis for most antibiotics, but there is insufficient data on other processes such as biodegradation and sorption.

Summary: This study compared the performance of a fixed bed hybrid biological reactor (FBHBR) and a conventional activated sludge reactor (CAS) in treating synthetic oilfield produced water. The results showed that FBHBR could maintain high removal efficiency under different hydraulic retention times and had wider bacterial diversity. The similarity between the bacterial composition of the free sludge and the biofilm in FBHBR suggests the important role of biofilm detachment in bacterial development.

Summary: Pharmaceutical products have become indispensable in life, with indirect exposure through water potentially causing negative effects. Therefore, it is crucial to consider and characterize the efficiency of pharmaceutical removal during wastewater and drinking-water treatment processes. Various conventional and advanced wastewater treatment technologies are capable of removing pharmaceutical compounds, while drugs and their metabolites can also undergo natural degradation through attenuation processes.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
