This study aimed to refine the N2O emission factor originating from treated sewage water by conducting year-round research on the production of dissolved N2O in rivers with varying concentrations of organic matter, N, and dissolved oxygen. There were differences in the N2O emission factor derived from the nitrification reaction of ammonium (NH4)-N due to the impact of N pollution load caused by the inflow of treated sewage water into rivers with different water qualities. The calculated N2O emission factor for rivers with relatively high water quality concentrations was 0.0028 kgN2O-N kgNH4-N-1, and the calculated average N2O emission factor originating from treated sewage water in rivers was 0.0026 kgN2O-N kgNH4-N-1.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 9","pages":"1022-1031"},"PeriodicalIF":2.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144080776","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-hundred and nine antibiotic compounds were reported across 80 studies, with sulfonamides, fluoroquinolones, and macrolides being the most frequently detected classes, while amphenicols and aminocyclitols were the least monitored. Advanced analytical techniques such as liquid chromatography and mass spectrometry are the most common approaches used for antibiotic quantification. Modeling efforts remain limited, with kinetic models, Risk Quotient (RQ) assessments, and Wastewater-Based Epidemiology (WBE) representing the main approaches identified.

This research deals with fermentation and hydrolysis by controlling the OFMSW storage (silage) conditions. Using only naturally occurring microorganisms as inoculum, OFMSW fermentation in a semi-continuous reactor at pH values of 4, 5, and 6 was performed. During 6 days, samples were collected and analyzed daily for VFAs, ethanol, and lactic acid. At pH 4, the main products were ethanol, lactic acid, and acetic acid; at pH 5, lactic acid predominated, decreasing after day 4; at pH 6, acetic acid formed rapidly and after day 1, the concentration remained constant. At pH 6, butyric acid reached the highest concentration of all VFAs. The microbial diversity increased with pH. Metataxonomic analysis supports the possibility that the fungus of the Pichia genus is responsible for ethanol production and that various bacteria are responsible for VFAs, lactic acid production, and acetogenesis. Acetogenesis was the main pathway for the decrease in lactic acid and ethanol over time.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 9","pages":"1044-1057"},"PeriodicalIF":2.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144080770","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}

Sediment beds extending over the entire pipe (i.e., continuous deposition) and localized deposits were examined under different flow rates and outlet control conditions. Continuous deposition changes the cross-sectional area of the sewer pipe, while localized deposits act similarly to short bottom obstructions. The energy losses induced by a localized deposit at various locations were found to be nearly identical, particularly in cases with backwater effects. To illustrate the relationships between the flow rate, water level, and deposit characteristics, hydraulic performance curves can be developed. The inverse problem, which involves estimating parameters characterizing sediment deposition using observed flow rates and upstream and downstream water levels, can be solved by matching hydraulic performance curves with numerous scatter points from actual monitoring data to obtain the best fit. As there is a wide range of sediment deposition patterns that result in the same overall energy loss, the concept of equivalent sediment bed height is introduced to be applied in real-world scenarios.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"91 9","pages":"1058-1076"},"PeriodicalIF":2.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144080772","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}

Studies have been conducted to evaluate its potential reuse in various processes such as agriculture, construction material manufacturing, pollutant absorption, and its reuse as a coagulant. This study evaluated the recovery of aluminum via acid treatment in WTS from a drinking water treatment plant (DWTP) that supplies water for a population of 413,484 inhabitants, using different pH levels and mixing speeds. The efficiency of the recovered coagulants was evaluated for the removal of color and turbidity in raw and wastewater. The main results showed a maximum aluminum recovery at a pH of 1.5 with values up to 810.5 mg Al/L, with pH being the most influential factor in the process. The removal of color and turbidity of 95.84 and 97.06% were achieved in wastewater and 69.78 and 69.73% in raw water, respectively.

Besides, sewage treatment plants (STPs) play a crucial role in further adding to the microplastic pool of the environment, especially in water and soil resources. As conventional STPs are not primarily meant to remove microplastics, treated effluent and sludge contain a significant amount of microplastic items which are ultimately discharged into the surface water/soil. The present study investigated the role of selected STPs of Central India in contributing microplastics to the environment. Inlet, outlet, and sludge samples were collected from seven STPs and analyzed for the presence of microplastics. Microplastics were found in all samples with higher amounts in the inlet samples (3-35.5 items/L) compared to the outlet samples (2-13.5 items/L). Nevertheless, sludge samples showed the highest amount of microplastics (16-389 items/kg) for all the STPs under study. Size, shape, color, and chemical composition of microplastics was varied with considerable presence of polyethylene, polypropylene, polyethylene-terephthalate, polyvinylchloride, polystyrene, polyamide, polyacrylamide, polyester, and polyurethane. Discharge of these microplastic items in the surface water and terrestrial ecosystems may result in serious consequences for ecology and human health.

The microorganisms were immobilized on biofilm carriers, achieving significant reductions: 83% COD, 93% turbidity, and 67% oil and grease. For the second method, we employed a UV-Fenton-based advanced oxidation process, optimizing Fe2+ dosage (42.4 mg/L) and H2O2 concentration (412.1 mg/L). This process demonstrated substantial reductions: 89% COD, 95% turbidity, and 72% oil and grease.
