The ratio of channel length to breadth (α) and the ratio of channel width to depth (β) of a serpentine flow channel on Escherichia coli inactivation efficiency were investigated. Simulations revealed that when α was 1.0, the flow channel had a uniform velocity distribution and performed the longest microbial residence time. Furthermore, biodosimetry tests indicated that when β was 1.0, the reactor resulted in a maximum inactivation efficiency of 3.7 log when the distance between the UV LEDs and the water was 11.5 mm. The optimal aspect ratio β led to the ideal balance between microbial residence time and UV irradiance, resulting in the highest UV fluence (10.6 mJ/cm2) for the bacteria. The inactivation efficiency observed at the aforementioned aspect ratio was approximately 48% higher than that observed at an aspect ratio of 2.56. Additionally, decreasing the distance between the UV LEDs and the water from 11.5 to 3.5 mm enhanced the inactivation efficiency at all aspect ratios because of the considerable increase in UV irradiance in the water.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-11"},"PeriodicalIF":2.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556319","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}

Several studies have dedicated efforts to treat the residue from coffee processing, while recovering lignols of industrial interest. Given this scenario, the nutrients in the coffee husk can enhance microbial growth, providing optimal conditions for the microorganisms to produce metabolites that may have medicinal properties. Deep eutectic solvents (DES) are a class of solvents and/or catalysts designed on demand for specific uses, being used to enhance extraction processes of coffee husk. Our present study was successful establishing conditions where the coffee husk enhanced the growth of microorganisms from two Brazilian biomes, the endophytic fungus from Cerrado and the actinomycete, from Atlantic Rainforest in Boraceia, São Paulo. The DES composed by ChCl/LA (1:10) was selected as cosolvent for the extraction, while it also optimized microbial cultivation conditions. Coffee husk was an excellent supplement for culture media, once the fungus FE316 produced Fumiquinazoline A, Tripprostatin B and Pseurotin A, while the actinomycete AC154 produced Trichorozin-IV as metabolites only expressed when in addition to the coffee husk.

The objective of this bench-scale study was to compare the effectiveness of several NaOCl, NaOCl-NaCl and NaCl regeneration solutions on the performance of a zeolite column loaded with a synthetic EIMWW. The NaOCl experiments confirmed that effluent pH, total chlorine level, and free chlorine levels during the chlorine regeneration were positively related, thus indicating that ammonia is oxidized to nitrogen gas accompanied by production of hydrogen ions. This led to the regeneration of TAN-containing sites but it also regenerated sites containing K and Ca, this appears to be accomplished through the Na ions in the NaOCl solution and H+ ions generated in the breakpoint chlorination reaction. The three regeneration schemes worked effectively, they did not significantly impact TAN uptakes and TAN selectivity. The NaOCl-NaCl regeneration scenario was superior to the NaOCl regenerations as it was faster and resulted in shorter low-pH periods that may damage the zeolite. And unlike the NaCl regeneration, the NaOCl-NaCl used regenerant was essentially TAN free, so it permits regenerant reuse and avoids creating a secondary waste stream. Thus, zeolite column treatment coupled with NaOCl-NaCl regeneration is a practical approach for the treatment of TAN-laden EIMWW.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-14"},"PeriodicalIF":2.2,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143556315","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 results indicate that metal ions inhibit CB biodegradation, with the most pronounced inhibitory effects observed at concentrations of 10.0 mg/L (Zn²⁺), 50.0 mg/L (Fe³⁺), 2.5 mg/L (Cd²⁺), and 3.0 mg/L (Hg²⁺).

We utilise the environmentally extended multiregional input-output (EE-MRIO) model based on China's 2012 and 2017 provincial MRIO table. The empirical finding demonstrate that emission responsibilities assigned to the ICT sector under CBA is greater than those under SRA, IBA and PBA. Regional emissions are highly concentrated under the PBA and IBA. The absolute amount of ICT emission responsibility increased under all accounting method, but the increase in the national share varied significantly. The inter-sectoral carbon emission transfer pattern, shows ICT sector exhibits dual carbon lock-in effects, demonstrates strong supply-chain dependencies, upstream procurement anchored in energy-intensive sectors (S23, S14, S13), while downstream consumption shows path-dependent concentration in S23, S29. Inter-regional transfer exhibits significant regional heterogeneity. In economically developed provinces like Guangdong, Beijing and Zhejiang, the ICT sector has a significant downstream-pushing effect and notable upstream-pulling effect on other regions. Conversely, in less developed northeastern and northwestern provinces, the ICT sector, mainly serving local consumption, leads to minimal upstream and downstream carbon emissions effect.

If the filtrate enters a non-sterile environment, bacterial regrowth occurs. The question arises as to how much regrowth potential is removed by membrane filtration. This study investigated the extent of regrowth of autochthonous bacteria in water from a building with integrated ultrafilter and in treated wastewater that had undergone ultrafiltration in the context of water reuse. The 7-day regrowth of filtrates was reduced on average by approx. 69% and 20% compared to the non-filtered waters. To better understand the behaviour and kinetics of regrowth and how much of the nutrient pool is retained by stripping water of its biomass, three different water types (drinking water, river water and reservoir water) were subjected in a laboratory study to membrane filtration using pore sizes between 0.45 µm down to 0.05 µm. The reduction in the regrowth potential depended on the water type. Filtration reduced the 7-day regrowth potential most strongly in case of drinking water (≥70%), while the reduction was less pronounced for river water and reservoir water (approx. 40%). The kinetics of regrowth over 14 days differed significantly between the water types with peak regrowth reached fastest in case of filtered river water (4 days), followed by filtered reservoir water (4-7 days) and slowest in case of filtered drinking water (14 days). There were also distinct differences in the unfiltered waters, with positive regrowth in case of drinking water and negative regrowth in case of reservoir and river water.","PeriodicalId":12009,"journal":{"name":"Environmental Technology","volume":" ","pages":"1-12"},"PeriodicalIF":2.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143540849","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}
