Summary: Global warming has a clear impact on the natural water cycle, increasing extreme weather events and posing challenges to urban water supply systems. Diversifying water sources is a key to building resilience, and atmospheric water harvesting provides a direct point-of-use water source. Although it avoids the need for storage and distribution infrastructure, its high cost and low water generation rate limit its potential as a viable alternative to traditional water sources.

Summary: This study investigated the removal of PFOA and PFOS in constructed wetland coupled microbial fuel cell (CW-MFC) systems and their interactions with other elements. The results showed that the CW-MFC systems achieved a removal efficiency of over 96% for PFOA and PFOS, which were distributed throughout the system via wastewater flow and enriched in the electrode material and plants. However, the introduction of PFASs in the system led to a decrease in nitrogen removal and bioelectricity output, attributed to the accumulation of PFASs affecting microbial activity and community composition, damaging plant health, and impairing CW-MFC functioning.

Summary: The global outbreak of COVID-19 has had a significant impact on human society, and effectively blocking the spread of the virus is crucial for controlling the pandemic. Ozone-based inactivation and disinfection techniques have been proven to effectively kill the SARS-CoV-2 virus in various forms. However, the lack of unified information and discussion on ozone-based inactivation and disinfection in previous and current pandemics, as well as the absence of consensus on the main mechanisms of ozone-based inactivation, have hindered the establishment of best practices in utilizing ozone technology. This article reviews the research status of ozone disinfection on pandemic viruses, with a focus on sterilization kinetics and categorizing pandemic viruses into enveloped and non-enveloped viruses. The review aims to provide a useful reference for the safe and effective utilization of ozone in the post-pandemic era.

Summary: Drinking water supply in rural areas is a challenging issue, and low-cost, efficient water treatment processes are needed to provide safe and affordable drinking water. This study proposes and evaluates a bubbleless aeration BAC (ABAC) process with a hollow fiber membrane (HFM) assembly, which improves dissolved oxygen (DO) throughout the filter and enhances DOM removal efficiency. Results show that ABAC significantly increases DOC removal and decreases disinfection byproduct formation compared to a comparable filter without aeration. The proposed ABAC treatment, with its various advantages, is well-suited for decentralized drinking water systems in rural areas.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
