This study mainly focuses on providing an in-depth review of the characteristics of effluents, available treatment processes, and regulatory frameworks for managing five common commodity manufacturing industry effluents (textile, pulp and paper, dye, leather, and rice mill). All these manufacturing industries consume large amounts of water and subsequently produce tons of effluents. Direct disposal of these effluents in the open environment poses potential hazards to the environment and human health and requires mitigation before discharge. Different conventional technologies are available to treat these effluents, which are associated with certain merits and demerits and highlighted here. The review also emphasized the most frequently applied process technologies to reduce BOD and COD load from the effluents of particular industries, with their limitations. Therefore, assessing economically viable and sustainable wastewater treatment approaches is crucial. It is concluded that conducting cost-benefit analysis in terms of BOD and COD removal efficiency and life cycle assessment is a must to select the most economical and sustainable solutions for the existence of any technology.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"92 6","pages":"856-878"},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145201671","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 liquid fractions of PSs after TAP yielded 348 ± 66 L/kg CODadded of biogas. They produced up to 29 ± 7% of the biogas from hydrolysates. In contrast, the liquid fraction of WASs after TAP yielded 395 ± 34 L/kg CODadded of biogas and produced up to 77 ± 4% of the biogas from hydrolysates. Additionally, the dewaterability of WAS increased by about 54%, while the dewaterability of PS decreased by roughly 48% after thermal treatment. With digestion of the liquid fraction and disposal of the solid fraction in WAS treatment with TAP at pH 11, biogas production increased by 4%, and the discharged sludge volume decreased by 10%. Although net electricity generation decreased by 22%, the digester volume could be reduced by 90%, allowing for more capacity for co-substrate digestion in WWTPs.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"92 6","pages":"903-918"},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145201692","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 objective of this study was to evaluate the efficacy of a BRC in mitigating runoff quantity, reducing peak flow rate, and improving water quality parameters (i.e., sediment, nutrients, heavy metals, and indicator bacteria) 8 years post-construction. Total runoff volume reduction was substantial (83%), accredited to mature vegetation promoting evapotranspiration, canopy interception, and hydraulic properties of the mature BRC soil. Additionally, the BRC provided similar peak flow mitigation (median 93%) to newly constructed BRCs in the literature. Significant reductions in event mean concentrations and loads of sediments (>88%), particulate-bound nutrients (>60%), and heavy metals (>70%) were observed. In many cases, the BRC had better - or at least similar - pollutant removal efficiencies than younger BRCs. The excellent function of this BRC provides evidence that these systems may improve over time, given proper long-term maintenance.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"92 5","pages":"752-769"},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145064842","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}

Daily weather data during the wheat-growing period were collected from 1970 to 2018 for the Amritsar district of Punjab state in India. To improve evapotranspiration estimation, a well-defined area of artificial intelligence called machine learning is used. To improve the accuracy of evapotranspiration estimation during the wheat-growing period, a model was developed by random forest (RF), support vector machine (SVM) and artificial neural network (ANN) using different weather input combinations. Based on the evaluation done using various standard statistical criteria during calibration and validation performance of RF was found to be best, followed by SVM and ANN. The model developed by (Tmax, Tmin, RHM, RHE and Rs) weather input combination was ranked first. Two weather input combinations (Rs, Tmax) and (Rs, Tmin) performed excellently by RF and SVM, while the weather input combination (Tmax, Tmin) performed excellently by the ANN. Hence, these input combinations can be used in the estimation of evapotranspiration when the availability of data is limited. From this study, it can be concluded that instead of a large amount of weather data, ET0 estimation can be done with a few data points by the machine learning technique.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"92 6","pages":"819-842"},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145201725","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}

Physicochemical characterization revealed that BPP-slag exhibited the highest soluble P removal efficiency (92.17%) at 30 g L-1 dosage, attributed to its high metal oxide content (e.g., Ca2+, Mg2+).

Unfortunately, traditional water quality monitoring in sewers is expensive and not comprehensive enough to provide detailed data on pollution across an entire catchment. However, with the increasing digitization of society, alternative data sources such as mobile positioning data offer new opportunities to assess wastewater production and dynamics. In this study, we investigate the relation between mobile positioning data and wastewater flows in five catchments in Switzerland with different characteristics and sizes, using data from the largest Swiss telecom provider and simple multiple linear regression models. The initial results of this study are promising although the degree of correlation observed between mobile positioning data and wastewater production is rather low (R2 between 0 and 0.73) and varies greatly from catchment to catchment. As expected, we find nonlinear effects in the data that indicate that advanced models - incorporating factors like flow distances and dynamic travel times - are needed for reliable predictions. Also, data privacy issues limit its use in small catchments, highlighting the need for domain-specific preprocessing. This approach holds potential for urban drainage, wastewater treatment, drinking water, epidemiology, and climate adaptation.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"92 5","pages":"669-682"},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145065836","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}
