Summary: China has implemented stricter effluent standards for wastewater treatment plants in order to protect the aquatic environment, but this has come at the cost of increased resource consumption and greenhouse gas emissions. Our study finds that upgrading the standards to the Special Discharge Limit by 2030 would significantly increase electricity consumption and operating costs for the wastewater treatment sector, and also lead to substantial regional differences in terms of resource burden.

Summary: This paper analytically studies the long-run effects of renewable portfolio standards on electricity prices and finds that the effects depend on the nature of the long-run average cost. The paper also discusses the differences between the long-run effects and the short-run effects, as well as the effects of increasing the stringency of an existing standard versus introducing a new standard.

Summary: Anaerobic membrane bioreactors (AnMBRs) are a promising technology for water reuse, but there is currently fragmented evidence for their potential and efficacy in this regard. This article reviews the latest developments in municipal wastewater treatment using AnMBRs and evaluates their potential application for water reuse. The findings suggest that, under stable operation, AnMBRs can produce water suitable for agricultural reuse. However, without post-treatment, AnMBRs cannot meet non-potable reuse standards across important parameters such as COD, BOD5, NH3-N, and TP. The analysis of key operational parameters provides insights into the operation of AnMBRs for non-potable reuse, including influent water matrix, pH, temperature, hydraulic retention time, system, and membrane configuration. An assessment of post-treatment technologies highlights a tradeoff between cost and effluent quality based on the specific reuse requirements. The article concludes by discussing the challenges and limitations of using AnMBRs for reuse applications and outlines a pathway to maturity for effective treatment trains.

Summary: The salinity exchange process involves transferring salts from seawater or brackish water to treated wastewater to produce desalinated water for drinking purposes. This method has been successfully demonstrated using electrodialysis, showing promising results in laboratory-scale systems with low energy consumption. Further evaluation is needed for implementing this technology on a larger scale using real water.

Summary: The planned reuse of treated wastewater is considered an effective approach for sustainable water resources management. However, sociocultural acceptance might hinder its success. This study investigates the perceptions and social acceptability of individuals with higher education towards treated wastewater reuse. The results reveal that the public is more receptive to indirect uses but strongly rejects direct reuse. Education level correlates with knowledge about sanitation issues but not with the acceptability of treated wastewater reuse for different purposes.

Summary: Morocco, a water-scarce developing country, aims to increase treated wastewater reuse for irrigation agriculture. However, the current regulation needs improvement to ensure more efficient technologies and address environmental and health risks. The study demonstrates the feasibility of increasing wastewater reuse and emphasizes the importance of considering quality standards, water scarcity, and cultural perception for optimal solutions.

Summary: This study aims to explore the interactions between electricity consumption, disposable income, wastewater discharge, and economic growth in 14 Chinese megacities. The findings suggest that a decrease in electricity consumption efficiency leads to a reduction in disposable income and an increase in wastewater discharge intensity, while an increase in wastewater discharge intensity also lowers power efficiency. Furthermore, the development of these cities still comes at the cost of polluting the water environment. Policy implications are proposed to avoid negative interactions that hinder sustainable development.

Summary: Improving sewage discharge standards can reduce the eutrophication potential of the system, but increases the impacts on fossil energy depletion, global warming potential, human toxicity, freshwater ecological toxicity, and acidification potential. It is necessary to decrease the moisture content of dewatered sludge and prioritize physical methods for advanced treatment, and use clean energy to minimize trade-offs with other environmental impacts. The efficiency of energy recovery in the sludge disposal system is critical to the total environmental impact of the entire system, offering opportunities for improvements.

Summary: This study investigates the feasibility of replacing chemical fertilizers with treated wastewater for agricultural irrigation and fertilization. A double modeling method is proposed to optimize crop production and minimize environmental costs, taking into account the nutrient concentration in the reclaimed waters. The results show that high levels of crop production can be achieved through wastewater irrigation, but there are limitations when the nutrient concentration is low.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
