The models aim to predict the periods where significant peaks of salinity occurs, whereas the tools aim to distribute the wastewater and reclaimed water streams to diverse applications (industrial, agricultural) and/or treatments (conventional treatment, reverse osmosis) to maximize the amount of wastewater reused in efficient and sustainable way. During the 2D simulated period, wastewater conductivity was in range of 2100-2700 µS·cm-1. Although this conductivity was over the limit required for industrial reuse, the digital solution implemented in this study enabled to recover 71% of the total wastewater produced for industrial purposes and 10% for irrigation, only discharging 19% of the total.

In this study, Z-scheme heterojunction BM-x composites consisting of bismuth bromide oxide (BiOBr) and iron-based metal-organic backbone (MIL-100(Fe)) were successfully synthesized using ethylene glycol as a solvent. The composites were characterized using various techniques. BM-x exhibit abundant functional groups, large specific surface areas, and narrow band gap energy, thus provide numerous active sites for catalytic reactions and respond well to visible light. Notably, BM-7 displays remarkable catalytic activity in a visible light-activated permonosulfate (PMS) system and achieves a degradation rate of 99.02% over 100 mg/L gold orange II (AO7) within 60 min. The effects of BM-7 and PMS addition, initial AO7 concentration, initial pH, inorganic anions, and humic acid on the degradation system were investigated. The proposed mechanism of the Z-scheme heterojunction in the BM-7 photocatalyst demonstrates effective photoelectron transfer from the BiOBr conduction band to the MIL-100(Fe) valence band, resulting in excellent catalytic activity. Radical burst experiments identified 1O2, h+, and ·O2- as the main active substances. BM-7 has high stability and reusability, with a degradation rate reduction of only 14.48% after three recycles. These findings provide valuable insights into using persulfate combined with visible light.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 4","pages":"363-381"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143524732","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}

In this study, the MPs' removal efficiency of a full-scale wastewater treatment plant (WWTP) and the internal interaction of microorganisms, antibiotic resistance genes (ARGs), and heavy metals with MPs were investigated. The dominant MPs in urban sewage were polyurethane (PU), acrylate copolymer (ACR), fluororubber, and polyethylene. MPs in wastewater were removed by WWTP with a total efficiency of 76%. The removal efficiencies of ACR, ethylene-vinyl acetate copolymer, polybutadiene, poly(tetrafluoroethylene), polystyrene, and polypropylene reached 100%. The highest concentration of MPs PU in the influent got a removal efficiency of 93.41%. The interactions between MPs, heavy metals, microorganisms, and ARGs involved adsorption, hydrogen bonds, coprecipitation, and polar interaction. Heavy metals and MPs formed larger aggregated particles, which were removed in the primary process. Heavy metals accumulated in sludge pose ecological risks to soil during landfill or compost to fertilizer. The release of MPs from WWTPs leads to accumulation in organisms and soil. It may affect the entire food chain and promote the transmission of ARGs in the environment, posing potential threats to the entire ecosystem.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 4","pages":"438-452"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143524726","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}

A comprehensive exploration of uncertainty quantification resulting from errors in ET in hydrological model simulations is presented, highlighting the imperative to scrutinize this facet amidst diverse uncertainties. There are two approaches for addressing uncertainty in potential evapotranspiration (PET) inputs as discussed: directly considering uncertainty in PET data series or accounting for uncertainty in the parameters used for PET estimation. Furthermore, details are provided about the existing error models for PET measurements, revealing a limited number of studies that specifically account for ET-related uncertainties. Researchers commonly address ET errors by considering both systematic and random errors; some studies suggest that systematic errors in PET have a more substantial impact compared to random errors on hydrological model responses. In summary, the objective of this paper is to offer an in-depth exploration of uncertainty associated with PET inputs and their influence on hydrological modeling.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 3","pages":"235-251"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415490","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}

As a crucial distributary, the Hooghly River is significantly impacted by human activities, particularly near ferry terminals and pilgrimage locations. Water samples (4 L) were taken from eight critical sites during pre- and post-monsoon periods at high tide, concentrating on important physico-chemical and biological attributes. Though pre-monsoon water quality largely adhered to BIS guidelines, heightened chemical oxygen demand and total coliform (TC) levels indicated potential pollution hotspots, likely caused by ferry movements and religious gatherings. Post-monsoon data revealed acceptable pH and temperature ranges but flagged concerns due to increased biochemical oxygen demand and TC counts, especially in high-traffic zones. The water quality index varied between 213 and 282, with a higher pre-monsoon value of 282 and a post-monsoon value of 213, primarily influenced by total dissolved solids, hardness, alkalinity, and conductivity. The comprehensive pollution index ranged from 1.30 to 1.33, surpassing the acceptable limit.

The initial transportation of urban pipe network systems plays a critical role in this process. These systems involve processes such as fermentation, hydrogen production, acetic acid production, and methane production, generating gases, such as methane and carbon dioxide. Despite their importance, the mechanisms underlying entropy changes during organic matter degradation remain underexplored. This study establishes a 1,200-m-long urban sewer pilot system to analyze pollutant degradation through reaction equations. A novel method, based on standard molar reaction enthalpy changes, is developed to calculate entropy changes, revealing distinct stages of entropy increase. Results indicate that environmental entropy rises primarily during sugar degradation and acetic acid production, while entropy decreases during glucose degradation and methanogenesis. During sewage transport, the heat released from pollutant degradation exceeds that associated with greenhouse gas emissions, leading to a general increase in entropy in the external environment. The findings of this study could help to predict the actual influent quality of wastewater treatment plants and facilitate the optimization of wastewater treatment.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 4","pages":"424-437"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143524725","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}
