Sponge city green infrastructure offers a solution to flooding and pollution, providing additional benefits like recreation and clean air. However, understanding public preferences for sponge city green infrastructure's ecosystem services and balancing its co-benefits poses challenges, especially regarding financial sustainability. This study used a discrete choice experiment with 1,154 residents from three Chinese sponge cities to assess the monetary value of five sponge city green infrastructure benefits: improving black and malodorous water bodies, flood prevention, mitigating urban heat island effects, rainwater reuse, and landscape recreation. Analyzing data via the mixed logit model, distinct preferences for sponge city green infrastructure benefits emerged. Residents across all cities were significantly willing to pay for rainwater reuse, indicating a gap in existing research. Preferences varied for other benefits, with positive responses for water body improvement and flood prevention but indifference towards heat island effect and mixed views on landscape recreation. This information is crucial for stormwater managers to optimize sponge city green infrastructure design and fee evaluation.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"93 1","pages":"39-64"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145971119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Confirming or rejecting this hypothesis is critical, given the escalating economic and environmental costs of nutrient-induced ecosystem imbalances which amount to billions annually in water treatment, agricultural losses, and biodiversity decline worldwide. This review achieves its breakthrough by synthesizing insights from academic papers, patents, and industry reports, uncovering interdisciplinary links between polymer chemistry, environmental engineering, and agricultural science that enable novel modifications to polymer composites. The growing market for next-generation adsorbents and fertilizers, driven by stricter nutrient discharge regulations and demand for sustainable inputs, presents profit-driven business opportunities.

The experiments are conducted for 5 to 30 mg/L, 1 to 2 kg, and 1 to 6 for Ci, maa, and MR, respectively. The effect of brine recirculation on the investigated system is also reported in this paper. The obtained results have shown an enhancement of up to 21% in the value of GOR with this system. Moreover, nearly 80% of the fluoride disposal to nature as concentrated brine can be prevented using the adsorption unit. The current study is carried out to prevent fluoride disposal in the reject stream. However, the proposed system can obtain freshwater at the community level without disposing of harmful contaminants in rejected water by incorporating other adsorption materials.

Anammox bacteria were successfully enriched from river sediments in a fixed-bed reactor using a nonwoven fabric as a support medium. Subsequently, the bacteria were immobilized onto porous polyvinyl alcohol carriers, demonstrating stable attachment and enhanced nitrogen removal efficiency. Performance evaluation experiments confirmed a high nitrogen conversion rate of 4.3 kg-N m-3 d-1 with stable long-term operation even under increasing nitrogen loading rates. This approach eliminates the need for external bacterial sources, enabling cost-effective and sustainable nitrogen treatment in regions where anammox technology has not yet been applied. The findings highlight the potential for localized wastewater treatment using indigenous microbial communities, with microbial analysis revealing the predominance of Candidatus Brocadia on the carriers, supporting stable nitrogen removal even under increasing loading rates. These insights emphasize the value of exploring adaptations that can enable effective operation under a broad range of temperature conditions.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"93 2","pages":"131-145"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146107429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study proposes a remote sensing method to quantify blue WF (BWF), green WF (GWF), and total WF (TWF) for crops in the upper Cauvery River Basin (UCB) using evapotranspiration (ETa) datasets derived from the vegetation coefficients (Kv), rather than relying on generalized FAO Kc tables. Using a stacked ensemble algorithm, study downscaled ETo and rainfall to a 500 m. Fine-scale seasonal BWF, GWF, and TWF for selected crops were mapped for the study period from 2015 to 2019. Our results show that while most crops predominantly depend on GW with minimal blue water extraction, paddy (Summer-IRR) and ragi (Rabi-RF) exhibit disproportionately high BWF, indicating critical hotspots of irrigation pressure and groundwater stress. Limited rainfall makes summer paddy strongly reliant on irrigation (BW), whereas Kharif maize utilizes GW, underscoring significant implications for water management policy. The high BWF and GWF values for ragi in 2016 highlight the impact of drought on WF, representing a distinction. This work provides a reference regional dataset of BWF, GWF, and TWF for the UCB, supporting improved understanding of water consumption dynamics, thereby informing future agricultural water management planning.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"93 2","pages":"202-226"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146107337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a novel soft sensor framework based on an adaptive long short-term memory (LSTM) ensemble for influent water quality prediction. The framework integrates a temporal pattern attention LSTM (TPA-LSTM) model with preprocessing techniques, including the Hodrick-Prescott Filter (HP) for trend extraction and density-based spatial clustering of applications with noise (DBSCAN) for anomaly detection. Missing data are addressed using Newton's Interpolation Method. This combined HP_DBSCAN approach extracts informative features and enhances data quality. The TPA-LSTM model is trained on the preprocessed water quality dataset, enabling accurate prediction of key parameters (e.g., BOD, COD, NH3_N). Comparative analysis demonstrates the superior performance of this hybrid-algorithm model over a single LSTM, highlighting the benefits of the adaptive ensemble approach. The hybrid-LSTM model, in comparison to the single LSTM, has improved the average fitting correlation for seven water quality indicators by 52.7% and reduced the prediction error by 62.1%. Experimental results validate the effectiveness and applicability of the proposed soft sensor for influent quality prediction in WWTPs.

Analyses followed the WHO and Ethiopian standards, with spatial-temporal variations evaluated via one-way ANOVA and Pearson correlation. The results were compared with the WHO and Ethiopian standards, and residual chlorine was monitored at 2-h intervals (four times per sampling day) during monthly sampling events conducted over three consecutive months in both dry and wet seasons. Most parameters met standards; however, iron in boreholes, TDS in BH2, and turbidity in the spring (wet season) exceeded permissible limits. Total coliforms occurred in all sources, while chlorine levels were excessive in reservoirs (up to 8.7 mg/L) but low in distribution, revealing rapid decay and heightened contamination risk. Water quality declined from source to distribution due to weak chlorination, poor sanitation, and aging infrastructure. Strengthening chlorination, protecting springs, improving drainage and waste management, and regular monitoring are essential to ensure safe and sustainable drinking water for the community.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"93 2","pages":"164-184"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146107334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
