This study introduces a novel concept of joint regulation of urban agglomeration based on watershed features and spatial topological norms. From the perspective of urban agglomeration, three new modes are proposed to guide flood storage and drainage in plain cities: (1) storing before discharging, (2) discharging before storing, and (3) discharging while storing. The modes aim to facilitate coordination among neighboring cities in an urban agglomeration and enhance the temporal and spatial coordination of flood storage and drainage. Multi-layer tree rules are established to allocate modes to cities based on the spatial characteristics of flood risk, storage, and drainage performance. The fact case proves that the mode has certain practical applicability. There are 35, 151, and 30 plain cities that use DS, DWS, and SD modes, respectively, out of 221 total. Most urban agglomerations employ at least two different joint regulation modes. The multi-layer tree rules for mode allocation presented in this study provide theoretical guidelines for flood management in plain cities across various regions.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 6","pages":"714-730"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744048","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 aim of this study was to investigate the effects of polyacrylic acid-based nanoplastics (PANPs) on microorganisms in activated sludge. The PANPs were characterized in terms of their material composition, size, zeta potential, and additive content. Acute (30 min) and prolonged (up to 6 h) toxicity tests were performed to evaluate negative effects on heterotrophic and nitrifying microorganisms in activated sludge. In addition, ready and inherent biodegradability tests were performed to assess their degradation in the environment and within wastewater treatment plants, respectively. The results showed a significant acute inhibition of heterotrophic and nitrifying activity (up to 55 and 72%, respectively) at the highest concentration tested (100 mg/L, 30 min), primarily attributed to the presence of 1-dodecanol detected in the PANPs. This effect decreased with prolonged exposure, likely due to the volatilization of 1-dodecanol. Nevertheless, the PANPs were found to be non-biodegradable in both the ready and inherent biodegradability tests. Although PANPs do not appear to pose a long-term threat to the activated sludge, their persistence in the environment raises concerns about possible accumulation.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"626-638"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634624","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 study developed a cost-effective approach to reduce the phenolic content in OMW using modified granular-activated carbon (GAC). Commercial GAC, chosen for its high surface area and adsorption capacity, was modified via oxidative treatment with concentrated nitric acid and reductive treatment using 10 wt.% ammonia solution. The modified GAC samples were tested for phenolic compound (PC) adsorption from OMW under varying surfactant types, concentrations, and pH levels using a batch method. The optimized conditions revealed that reduced GAC at pH 9 achieved the highest removal efficiency, reducing the phenolic content by 88% after 48 h. Surfactants had no significant effect on the performance of reduced GAC. Desorption tests after 7 and 32 days indicated a minimal release of PCs, confirming strong binding to the GAC surface. These findings demonstrate the potential of reduced GAC as a sustainable and cost-efficient solution for treating OMW, addressing the critical challenges in water resource management and environmental pollution in regions like Jordan.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"567-580"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634656","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}

One way to accomplish this is to treat and reuse spin cycle effluent from washing machines. The spin cycle, being the last washing cycle, yields comparatively cleaner effluent, necessitating less intensive treatment, rendering it an attractive target for treatment and reuse. This study presents the first instance of characterizing and treating this effluent. The average values for spin cycle effluent for chemical oxygen demand, biochemical oxygen demand, pH, conductivity, turbidity, total nitrogen, and orthophosphate were found to be 241.8 ± 88.4 ppm, 36.9 ± 14.3 ppm, 7.2 ± 0.9, 223.4 ± 46.7 μS/cm, 85.9 ± 20.1 NTU, 7.2 ± 3.1 ppm, and 4.6 ± 1.7 ppm, respectively. The treatment study was conducted at a 2-L scale using aluminum electrodes in a bipolar setup and utilized three liquid and three solid detergents. The treatment process consisted of sequential utilization of electrocoagulation flocculation and granular activated carbon which resulted in excellent treatment, with a 92.7 ± 3.6% reduction in chemical oxygen demand, an 87.2 ± 9.7% reduction in total nitrogen, a 91.4 ± 2.9% reduction in orthophosphate, and a 93.3 ± 4.7% reduction in turbidity. Utilizing the reuse potential of the spin cycle effluent with this process will allow households to actively contribute to sustainable water management practices.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"482-500"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634670","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 reports generated by surveyors help companies to plan for the maintenance and rehabilitation of sewage pipes. A surveyor needs to record the water level at the start of every survey and any point of significant change in level. Recording the water level provides insight into the cross-section area being surveyed, highlighting any underlying issues with the pipe. An abrupt change in water level can indicate a poor gradient of pipe, a build-up of debris, or even hidden structural damage. However, manually recorded water levels are often unreliable due to factors like surveyor experience, the camera angle, light conditions, and pipe shape. In this paper, we have discussed and compared six methods for the automated estimation of water levels in sewage pipes. Using the segmentation masks extracted with DeepLabv3 as inputs into an Extra Trees regressor achieved the most accurate results. To perform an objective comparison of the techniques, mean absolute error (MAE), root mean square error (RMSE), and max error were used as evaluation metrics.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 6","pages":"746-756"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744049","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}

Low-impact development (LID) practices are effective in reducing urban runoff, but selecting optimal combinations based on cost, performance, and service benefits remains crucial. This study presents a comprehensive framework for optimizing urban stormwater management by integrating a simulation-optimization module, which consists of stormwater management model-SUSTAIN models, with a multi-criteria decision-making module. To guide decision-makers, it introduces two novel criteria - sustainability index, derived from reliability, resiliency, and vulnerability indices, and vegetated LID coverage to account for LID's extra environmental benefits such as air quality improvement and aesthetics, alongside cost. The proposed methodology is applied to Tehran's District 11, where four LID scenarios, including green roofs (GR), rain barrels (RB), bioretention cells (BC), porous pavements (PP), and vegetated swales (VS), are evaluated using the WASPAS method. Scenario 2 (RB, BC, and VS) is identified as the most favourable due to its cost-effectiveness, even though it has lower vegetated LID coverage than two of the other scenarios. This study offers a practical tool to balance multiple objectives in urban stormwater system design and management, promoting sustainability and cost-efficiency.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"654-668"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634619","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}

Many unrelated studies have introduced or used energy-related terms to describe changes to wastewater treatment plant energy balances based on these technological innovations. Unfortunately, these wastewater energy-related terms are not well defined in the literature, with many used interchangeably and/or inconsistently. To address this shortcoming, this study (1) identified and defined the most prominent energy-related terms in academic literature, (2) proposed a classification schema, and (3) explored trends in term usage over time. Energy-related terms identified from the literature were defined and classified based on the term's functional role in the context of wastewater treatment plant energy use. Specifically, each term was classified as a wastewater treatment plant's long-term energy 'state', a descriptive short-term energy 'condition' at the plant, or an energy 'mechanism' that drives a plant from one state to another. The trend analysis concluded that the development of energy-related wastewater literature has generally outpaced the baseline rate of academic publishing in all fields. The results of this study can ensure clear communication between actors in the wastewater treatment sector by standardizing definitions for energy-related terms.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 6","pages":"671-683"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743918","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 study reports a new method for improving ES low-temperature anaerobic fermentation for VFA production using peracetic acid (PAA) pretreatment and elucidates the underlying mechanisms. The results showed that at 10 °C, PAA significantly enhanced the release of organic matter during ES anaerobic fermentation, increasing the soluble chemical oxygen demand concentration in the fermentation liquid, thereby creating conditions for subsequent acidification processes and VFAs accumulation. When the PAA dosage was 9%, the production of VFAs reached approximately 239.5 mg COD/g volatile suspended solids (VSS), which was 1.47 times that of the control group. Mechanistic analysis revealed that PAA improved sludge hydrolysis and acidification under low-temperature conditions but inhibited VFAs consumption, increased the activity of enzymes related to the hydrolysis and acidification processes, and suppressed the activity of F420, thereby enhancing VFA accumulation.
