Summary: Considerable changes have been observed in recent years in surface waters' quality, such as an increase in dissolved organic carbon (DOC) concentrations and a shift in natural organic matter (NOM) composition towards low molecular weight (LMW), and these changes are expected to occur on a larger scale in the future. Given that surface water is the main source of potable water for many communities globally, these predictions are particularly concerning. Traditional treatment methods for surface water using coagulation are becoming inefficient due to the evolving water quality. The presence of natural organic matter in drinking water sources, its anticipated changes, and the related treatment problems are complex and urgent issues that require attention.

Summary: This study investigated the behavior and removal of nanoplastics (NPs) during conventional drinking water treatment processes. It was found that sand filtration had the highest efficiency in removing NPs, and slow sand filtration played a dominant role in the overall removal of NPs. These findings are valuable for estimating the NPs removal efficiency in typical DWTPs with similar water treatment chains.

Summary: Residual aluminum, specifically in the form of Ala-NOM complexes, is a significant contributor to nanofiltration membrane fouling in drinking water treatment. Increasing the concentration of both residual aluminum and coexisting natural organic matter aggravates membrane fouling. Residual aluminum produced from polyaluminum chloride has a higher membrane fouling potential compared to that produced from aluminum chloride.

Summary: Membrane ozonation using polydimethylsiloxane (PDMS) and polytetrafluoroethylene (PTFE) membrane contactors was used to treat bromide-containing, high-color natural organic matter (NOM) in groundwater. The study investigated the correlation between dissolved ozone concentration, water color, ultraviolet light absorption, bromate formation and various process parameters. The results showed that ozone dose played a major role in balancing bromate formation and NOM color removal, and could be controlled by adjusting gas concentration, hydraulic retention time, and Hatta number (Ha).

Summary: Microbubble technology shows promise in improving gas-liquid contacting processes, particularly in ozonation. Microbubbles enhance mass transfer, dissolved ozone residual, and compound removal. The improvement is attributed to an increase in specific interfacial area and a decrease in the mass transfer coefficient. No enhancement in hydroxyl radical production, bromate formation, or impact from background constituents was observed.

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 objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
