However, limited modelling studies have investigated the effect of sediment and solid waste accumulation on the performance of UDSs during extreme loading conditions. In this research, the influence of combined scenarios of sediment and solid waste deposition and extreme rainfall on urban flooding in the upper Lubigi catchment in Kampala was investigated. The collected high-resolution rainfall data and water level observations in combination with field observations were used for model calibration and validation. The results show three locations that account for over 50% of the flooded volume in the catchment, based on the existing conditions. A near-complete blockage of sediment and solid waste at three culvert crossings increased the flood volumes by up to 40% for higher (≥50 years) return periods and by up to 105% for low return periods (≤10 years). This research underscores the importance of using high-resolution rainfall data in flood modelling, as well as the necessity of improved UDS asset management, and effective solid waste and sediment management in order to achieve resilient and sustainable water management in cities.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 6","pages":"757-782"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744044","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}

Within the Circular Economy, this involves the circular exchange and reuse of water, energy, and resources among participating businesses, enhancing resource valorisation in manufacturing. However, as a distinct business model, InSym requires collaboration among multiple stakeholders working toward a shared goal, posing challenges in achieving mutually beneficial outcomes. Operations Research (OR) - particularly computer modelling and simulation techniques - can help mitigate risks in InSym implementation by enabling an experimental approach to decision-making. This paper presents a hybrid modelling framework to support InSym decision-making. The framework integrates four OR techniques: Agent-Based Simulation (ABS), Discrete-Event Simulation (DES), System Dynamics (SD), and Multiple Criteria Decision Analysis (MCDA) to develop a hybrid InSym model. ABS captures stakeholder behaviour, DES simulates operational processes, SD represents dynamic interactions, and MCDA incorporates stakeholder perspectives. The model evaluates collective treatment strategies for olive mill wastewater, addressing key challenges such as scattered small-scale olive mills, seasonal wastewater discharge, and high organic loading. This innovative framework addresses InSym decision-making at operational, tactical, and strategic levels, transforming the economy-environment dilemma into a win-win scenario for olive oil businesses and local authorities.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"501-523"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634664","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 requires low-salinity water, but this area is frequently affected by saline intrusion, thus creating water-related conflicts between the different economic activities. This study proposes a digital solution that combines dynamic simulation model (that predicts seawater intrusion and runoff) with digital tools, i.e., smart equalization (control algorithm) and matchmaking platform (decision support system). 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. The approach implemented in this study would be very useful to be replicated in coastal areas where saline intrusion is relevant.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 3","pages":"280-294"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415442","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 conditions tested were 19.3 mA/cm2, 30 min, and 3.8 L/min. For AD tests, raw and pretreated WAS were digested in an OxiTop® OC 110 apparatus for 15 days. Inactivation of faecal coliforms, Salmonella spp., and bacteriophages reached more than 5 logs when EO was combined with AD. In contrast, EO alone did not inactivate these parameters, while AD achieved eliminations around 3 logs. Moreover, the combined process inactivated 91% of the initial viable helminth eggs, considerably higher than AD (29%) and EO (0%). The results suggest that EO separates extracellular polymeric substances and segregates particles, including microorganisms, that are exposed to environmental factors (e.g., volatile fatty acids or ammonia) during AD, showing a synergistic effect.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 3","pages":"311-320"},"PeriodicalIF":2.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415443","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 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}

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}
