Summary: This study compared the chemical properties and fouling potential of biopolymers extracted from secondary wastewater effluent and surface water during ultrafiltration. It was found that EfOM biopolymers were enriched in protein structures and caused more irreversible fouling compared to NOM biopolymers. Additionally, the presence of divalent cations increased the irreversibility of fouling, with a more significant impact on NOM fouling.

Summary: A new and scalable method for isolating extracellular vesicles (EV) from Citrus lemon juice samples was developed. The methodology involved preconcentration of the sample using ultrafiltration (UF), followed by purification using size-exclusion chromatography (SEC) and final preconcentration of the eluates. The isolates were found to contain exosome-like vesicles, exocyst-positive organelle (EXPO), and microvesicles through transmission electron microscopy and proteomic analysis. The efficiency of the isolation steps was evaluated using bicinchoninic acid assay (BCA), nanoparticles tracking analysis (NTA), and capillary electrophoresis (CE), showing good correlation between them. CE was proven to be a comprehensive tool for monitoring the EV isolation process, enabling the detection of soluble contaminants, macromolecular aggregates, and vesicle heterogeneity through fluorescent staining of encapsulated nucleic acids.

Summary: This study investigated the chiral inversion of 2-arylpropionic acids (2-APAs) and the associated microbial community under anaerobic conditions. The results showed diverse chiral inversion behaviors of 2-APAs, with some compounds exhibiting unidirectional inversion and others showing bidirectional inversion. Several bacterial genera were identified in the anaerobic digesters and predicted to have the gene involved in chiral inversion, but they were present at low abundances, explaining the limited extent of chiral inversion observed in this study.

Summary: Sebum from sebaceous glands is a rich source of volatile organic compounds (VOCs) that can be sampled non-invasively from the skin surface. However, there is a need to establish the effects of sampling approaches and environmental factors on sebum VOC profiles. In this study, a more standardized skin swab sampling approach was investigated, and the impact of sampling materials and preparatory conditions on VOC profiles was assessed using thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). The study highlights the importance of rigorous controls in sebum sampling and provides recommendations for future research.

Summary: Continuous online monitoring is important for ensuring reliable water quality outcomes and effective removal of microbial substances during advanced wastewater treatment processes. However, most microbial indicators cannot be continuously monitored online. This study used a combined ozonation-biological media filtration process to reduce microbial indicator concentration and developed models for predicting microbial indicator concentration changes. Machine learning algorithms were applied to identify physico-chemical predictors and their associations with microbial indicator reduction. Support vector machines (SVM) with a Gaussian kernel classifier showed superior performance in microbial removal prediction. The study provides an efficient method to predict the effectiveness of the O-3/BMF process in removing microbial indicators based on commonly measured physico-chemical parameters.

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: 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: Green walls provide a new and on-site method for treating and reusing greywater in urban areas. 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: Size exclusion chromatography (SEC) coupled with optical measurements is a popular method for analyzing dissolved organic matter (DOM) based on molecular size. This study utilized SEC with in-line absorbance and fluorescence scans to determine the apparent fluorescence quantum yield (Phi(f)) of DOM as a function of molecular weight (MW). The method was applied to measure Phi(f) of unknown DOM samples and to observe changes in Phi(f) following ozonation. This method provides a way to identify highly fluorescent size fractions of DOM for further analysis of its chemical composition and changes through different processing mechanisms.

Summary: The increase in natural organic matter (NOM) in boreal and north European surface waters poses challenges for drinking water treatment plants (DWTPs). High-frequency measurements from online spectrophotometers are commonly used in modern DWTPs to measure the chromophoric fraction of dissolved organic matter (CDOM) over time. These measurements can provide valuable information to optimize NOM removal and diagnose underperformance at the DWTP. However, the large datasets generated by automated monitoring systems require careful preprocessing and signal processing for interpretation. This work introduces AbspectroscoPY, a Python toolbox for processing time-series datasets collected by in situ spectrophotometers. The toolbox addresses challenges in data preprocessing and provides automated functions to compute various spectral metrics for the time-series data. It was demonstrated to be useful in identifying and quantifying variations in treated water quality over time. This toolbox represents a step towards automated early warning systems for detecting and responding to changes in water quality that may affect treatment performance.

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.
