Summary: The research showed that briefly stopping the filter did not significantly reduce its efficiency, but prolonged operation before stopping could adversely affect the filtrate quality. After restarting the filter, the removal efficiency for coarser particles decreased for a longer period and to a greater extent compared to finer particles.

Summary: The study evaluates the operational energy and GHG emissions of a municipal wastewater treatment technology in Mumbai Metropolitan Region, India, showing the energy intensity for plant operation and COD removal. Additionally, there is analysis on the embodied energy in chemicals and building materials during the plant's life cycle. The study also found a correlation between wastewater inflow and energy consumption in wet-well pumping and blowers.

Summary: The study using an EU27 multiregional input-output model reveals environmental inequality in the CWE nexus. The EU27 countries significantly reduced CO2 emissions, water utilization, and energy consumption compared to the rest of the world in 2014, while maintaining economic output. This has profound effects on the global environment, with Germany, France, and Italy being the biggest beneficiaries in the EU27 CWE nexus.

Summary: Access to safe drinking water is a significant concern in China, particularly in rural areas. While the government has made efforts to increase access to tap water, the rate is still considerably lower than in urban areas and unevenly distributed across the country. Additionally, electricity, mainly electric kettles, contributes to the boiling of water, with 69% of households using this method. Further intervention and investment are necessary to improve drinking water safety in poor and remote rural areas.

Summary: This study evaluated the influence of water and wastewater treatment on reducing the concentrations of trace elements in drinking water in the Western Pomerania Voivodeship in Poland. The results showed that both water treatment and wastewater treatment were effective in reducing the concentrations of harmful elements, while essential elements remained within acceptable limits.

Summary: This study numerically models and comprehensively analyzes the energy, exergy, economic, and environmental impacts of a solar collector. The use of certain nanofluids is found to significantly save energy and water consumption in the collector. The study also reveals the influence of inlet temperature on the collector's efficiency and energy production cost.

Summary: The atmospheric water generator (AWG) is a commercially available device that produces large volumes of water from the air in a short time. It can be used in most regions of the world to address chronic and acute drinking water scarcity. However, the impact of air chemical composition on the quality of AWG-produced water is not well understood. In a survey conducted in a heavily polluted industrial environment, AWG-produced water was found to meet drinking water standards for most contaminants, except for specific parameters such as nickel, dichloromethane, and ammonia.

Summary: This study assessed the impact of weak magnetic fields on drinking water microbial communities using flow cytometry. The results showed that the applied magnetic fields selectively promoted the growth of certain microbial groups under nutrient-rich environments and inhibited the growth of others. These findings suggest that magnetic field treatment can enhance biostability and potentially serve as a sustainable method for microbial community management.

Summary: Contaminated industrial wastewater is a severe cause of health diseases. This study collected cross-sectional data from manufacturing firms in order to investigate the factors influencing the intention to install wastewater treatment plants and provide policy suggestions to developing countries' governments. The results showed that environmental knowledge, installation cost, firm reputation, and corporate social responsibility positively influence the intention, while awareness of the risk associated with contaminated wastewater has a negative influence. Government incentives, on the other hand, do not have an impact. The study also found that firm size moderates the relationship between variables. Overall, this study provides valuable insights and policy suggestions for addressing water scarcity and health issues caused by contaminated industrial wastewater.

Summary: The demand for new buildings and infrastructure poses considerable strain on the natural environment, requiring the use of tools like life cycle assessment to assess and improve environmental performance. The EPiC Database in Australia provides hybrid embodied environmental flow coefficients for construction materials to address incomplete process data and improve the environmental performance of construction projects.

Summary: A data-driven Bayesian Network (BN) model was developed for a large Australian drinking water treatment plant, which can predict the probability of different incoming raw water quality ranges during wet weather events. The model relies on expert consultation and historical data of different types and amounts. It can be used to assess different dam water release scenarios for mitigating water quality challenges in drinking water treatment.

Summary: Despite considerable efforts, we are not on track to meet the SDGs by 2030. The Sino-US trade war and the COVID-19 pandemic have increased trade protectionism, which may hinder the achievement of the SDGs. This study examines the impact of international trade on global energy and water inequality and finds that while international trade can alleviate energy inequality, it has a minor effect on improving global water inequality.

Summary: This study presents a comparison of different bottled drinking water brands available in Lahore, Pakistan. The analysis of physical, chemical, and microbiological parameters revealed significant differences in the quality of water. One brand was found to have higher levels of sodium and arsenic than permissible limits, while some brands were deficient in essential minerals. The data presented in this study can serve as baseline information for future reference.
