Conducted in a juice factory in Nafplio, Greece, the primary objective is to explore the recovery of polyphenols from water by-product streams generated during orange juice production. The research aims to evaluate the effectiveness of a mobile wastewater treatment unit in selectively adsorbing polyphenols onto a polymeric resin. The following three extraction methods are compared: conventional solvent extraction, subcritical water extraction (SWE), and supercritical CO2 extraction (SFE). To determine the most efficient extraction method, the polyphenol profiles of the extracts were analyzed using UHPLC-Q-Orbitrap-MS/MS, identifying flavonoids, terpenes, coumarins, and anthocyanins. SFE not only was the most efficient method but provided the most diverse and abundant profile. The research highlights the potential of converting industrial by-products that would otherwise be treated as wastewater, into valuable resources that generate revenue, promote circular economy practices, and enhance sustainability in the fruit and vegetable processing sector. The economic viability of polyphenol extraction is also discussed, emphasizing its significance and impact on various industries. The findings support integrating advanced extraction technologies to maximize resource recovery and minimize environmental impact.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"540-553"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634625","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}

Mathematical modeling of membrane bioreactor (MBR) treatment is a powerful tool for predicting effluent quality. In this study, a bioreactor coupled with a membrane filtration process (MBR) was employed to treat municipal wastewater. An experimental design based on the response surface methodology (RSM) was applied to investigate the effects of operating conditions, such as hydraulic retention time (HRT), aeration rate (AR), and transmembrane pressure (TMP), on the removal efficiencies of chemical oxygen demand (COD), total suspended solids (TSS), and total nitrogen (TN). The results demonstrated a strong agreement between experimental data and model predictions. Furthermore, the RSM results display the effects of the operating parameters and their interactive effects on pollution removal. The maximum removal efficiency was achieved, exhibiting 95% of COD, 99.7% of TSS, and 93% of TN. These findings provide the effective use of statistical modeling to enhance MBR process performance, achieving sustainable and energy-efficient conditions.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"453-468"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634658","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}

Al/nZVI/C@F granules were synthesized using a liquid-phase reduction method combined with high-temperature calcination. By comparing the removal of methylene blue dye by granules, the optimum preparation conditions were determined as follows: Fe:C = 5:1, fly ash = 50%, calcination temperature = 800 °C, and holding time = 1 h. Static batch experiments revealed that under optimal conditions (PFOA concentration = 25 mg/L, solid-liquid ratio = 30 g/L, pH = 3, reaction temperature = 15 °C), Al/nZVI/C@F achieved a PFOA removal rate of 97.83%. The removal efficiency of Al/nZVI/C@F (93.90%) was significantly higher than that of commercial iron-carbon (12.75%). After 45 days of dynamic column experiments, the removal efficiency of nZVI/C@F and Al/nZVI/C@F for PFOA (50 mg/L) remained above 60%, demonstrating strong practical application potential. Further adsorption-desorption experiments revealed that nZVI/C@F and Al/nZVI/C@F primarily removed 50 mg/L PFOA through adsorption. For a lower PFOA concentration of 0.5 mg/L, the defluorination rates were 53.2% for nZVI/C@F and 68.9% for Al/nZVI/C@F. High-performance liquid chromatography-tandem mass spectrometry was used to analyze the intermediates formed during PFOA removal, leading to a proposed degradation pathway.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"609-625"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634668","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}

Analytical probabilistic models (APMs) in conjunction with particle swarm optimization (PSO) were used to design a detention pond system at three sub-catchments of a watershed that discharge into a common point. The objective is to design multiple ponds upstream such that the pollution control target downstream is met at the minimum cost. Given the cost of purchasing land plus the cost of construction/maintenance of the ponds in the sub-catchments, the result shows that pond depths of 2.0 m in all three sub-catchments give the least total cost. A runoff control of 88, 94, and 90%, and pollution control of 59, 45, and 66% were obtained in Ponds 1, 2, and 3, respectively, while satisfying the overall watershed's pollution control target. A sensitivity analysis was conducted by varying the land costs and different performances were obtained. The APM/PSO model can search for the optimum design parameters that satisfy upstream runoff control performances and the overall pollution control target downstream. The advantage of the approach is that it can be applied to any combination of ponds in a larger watershed.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"592-608"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634617","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 IEDEO process showed excellent performance for the simultaneous removal of bio-refractory organics and inorganics in the chlorpyrifos wastewater. In contrast with the single EO process, the results of energy consumption, UV-vis spectra, and GC-MS showed that the oxidation performance for chlorpyrifos wastewater by IEDEO was carried out more efficiently. The biodegradability of the chlorpyrifos wastewater pretreated by IEDEO was significantly improved. The total salt removal (90.3 ± 2.1%) from the chlorpyrifos wastewater obtained by IEDEO was significantly higher than the 5.8 ± 1.6% removal attained with the EO process. The COD removal of chlorpyrifos wastewater by the IEDEO process was 25.5 ± 1.2%, and the energy consumption of the IEDEO process was 15.1 ± 1.6 kWh kg-1 COD at 2 h, representing a 60-65% reduction compared to the EO process. This indicated that the IEDEO process was a valuable pretreatment technique for biological treatment.

However, the EBPR process can experience upsets due to a lack of influent carbon or inadequate anaerobic zones. By using a sidestream EBPR (S2EBPR) process, carbon can be generated internally through fermentation processes and a higher anaerobic mass fraction can be attained in smaller volumes. This study investigates nutrient removal and microbial community trends in a full-scale S2EBPR demonstration at the Calumet Water Reclamation Plant. The study aims to improve a process model of the system by better representing the activity of glycogen-accumulating organisms (GAO) and potential competitors of phosphorus-accumulating organisms (PAO), which were found in high abundance in this study. Modifying anaerobic hydrolysis, GAO glycogen storage and ORP activity parameters resulted in model prediction improvements of approximately 5% for nitrate and nitrite and 10-60% for phosphorus. The study also uses shotgun metagenomic sequencing to profile denitrification pathways of PAO and GAO. It shows that denitrifying GAO may contribute to nitric oxide reduction to a greater degree than denitrifying PAO. This study improves process modeling predictions for S2EBPR and highlights the potential role of denitrifying PAO and GAO in combined phosphorus and nitrogen removal in S2EBPR.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 5","pages":"469-481"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634675","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 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}

During the rendering process, large amounts of condensate and housekeeping wastewater (CWW and HKWW), solids and greenhouse gases are released into the environment imposing a huge pollution threat. Rendering condensate wastewater also causes many issues that commonly affect biological treatment processes such as pH inhibition, nutrient deficit and temperature. Therefore, the main objective of this work was to simulate the nutrient removal from a sequencing batch reactor (SBR) through the differential nitrogen overload of CWW. With aid of simulation, results found that the current SBR system does not remove carbon and nitrogen as much as other biological systems. This is due to low biodegradation of chemical oxygen demand (COD), the high content of inert particulate carbon (XI), identified in the fractionation of HKWW, and the toxic and inhibitory effect of ammonium present in CWW. When the system is overloaded with nitrogen from CWW there is little removal of biochemical oxygen demand (BOD), ordinary heterotrophic organisms (OHO) outnumber autotrophic nitrifying organisms (ANO) and ammonium toxicity occurs, all contributing to a failure to remove nutrients.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 6","pages":"731-745"},"PeriodicalIF":2.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744040","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}
