Applying phosphate-based corrosion inhibitors to the system can exacerbate disinfectant decay by providing nutrients to biofilms growing inside premise plumbings. In this study, we evaluate the impacts of corrosion inhibitors on biofilms' structural and chemical properties that form in premise plumbing, and the resulting implications for disinfectant decay. Two commonly used phosphate-based (phosphate blends and phosphate) corrosion inhibitors were added separately to simulated drinking water for biofilm development over 1 to 2 years. Optical coherence tomography (OCT) imaging showed that the studied biofilms' thickness, porosity, and porous structure did not change after exposure to free chlorine for 24 h or monochloramine for 120 h. Compared with groundwater biofilms, phosphate-based biofilms had the highest overall porosity due to their many connecting channels. The phosphate-based biofilms consumed free chlorine or monochloramine at a faster rate than groundwater biofilms. Experimental results showed that phosphate-based biofilms consumed more monochloramine after 96 h of contact than other biofilms. A separate set of experiments involving disinfectant decay with suspended biomass material, together with the OCT results, provided parameters for a simplified quasi-first-order reaction–diffusion model so that predictive modeling of decay in biofilms under stagnation conditions could be attempted without parameter fitting. The biofilm modeling results provided a close estimate for free chlorine decay while underestimating monochloramine decay. In agreement with the experimental results, the model results indicate that the phosphate-based biofilms led to slightly faster free chlorine consumption and monochloramine consumption than groundwater biofilms and indicate that diffusion limitation imposed by biofilm pore structure on disinfectant decay is important. The study results suggest that using phosphate-based corrosion inhibitors may lead to a rapid depletion of residual disinfectant during stagnation in the presence of biofilms.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136102752","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}

Andrew Ramsburg","doi":"10.1089/ees.2023.0053","DOIUrl":"https://doi.org/10.1089/ees.2023.0053","url":null,"abstract":"Permeable reactive barriers (PRBs) are being considered for treatment where the discharge of nitrate plumes contributes to eutrophication (e.g., Cape Cod, MA). PRBs enhance denitrification through the addition of carbon-based amendments such as the injection of emulsified vegetable oil (EVO). The use of EVO to stimulate denitrification foregrounds aspects of carbon utilization, dosing, longevity, and secondary effects in ways that differ from the application of EVO at hazardous waste sites. The overall objective of this study was to develop and evaluate a process-based modeling approach for simulating denitrification stimulated and supported by EVO. A series of one-dimensional column experiments assessed emulsion retention, production of soluble substrate, and utilization of carbon for nitrate reduction. Retention of 5.5 g dispersed phase emulsion resulted in sustained reduction of nitrate (∼43 mg/day) at ∼2 m/day porewater velocity. Biokinetic processes underlying the model are based on the two-step denitrification description of the Activated Sludge Model (ASM) No. 3. Biokinetic processes were integrated within the flow and transport simulator COMSOL to simulate the column experiment. The model capitalizes on the biokinetic parameters available in the ASM literature to limit the number of site-specific fits of model parameters. Simulation results demonstrate how this approach can result in reasonable predictions, although model performance was enhanced by fitting two parameters—yield coefficients for nitrate and nitrite. Comparisons with existing biokinetic transport models that were similarly fit to the column data suggest that the better overall descriptions of the column data using the process-based model stem from a more robust handling of spatial and temporal distribution of biomass. Sensitivity analyses highlight the importance of accurately describing the transformation of complex carbon into soluble substrate, and the subsequent utilization of that substrate. This research establishes a foundation for exploring implications of carbon processing on dosing, longevity, and effectiveness in denitrifying PRBs.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136102748","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}

However, there is little documentation on the microbial community structures in real-world family farm digesters. This work compared microbial community structures in four family digesters with a near-by municipal digester. Included in the family digesters was a high-altitude family digester located on Mt. Everest in Mosi, Nepal (2,634 m elevation). Differences in the community structures included the prevalence in family digesters of Bathyarchaeota MGC-6. MCG-6 is an archaeal population putatively involved in autotrophic acetate generation and conversion of cellulose to sugars. In addition, Rikenellaceae DMER64, a population thought to degrade sugars, was more prevalent in the family digesters. The ratio of Methanothrix to hydrogenotrophic methanogens was higher in the family digesters. In addition, the dominant species of syntrophic hydrogen-producing bacteria differed. Syntrophobacter and Syntrophomonas species, documented for their critical roles in waste activated sludge digesters, were not detected. In conclusion, observed differences in microbial community composition suggested a capacity to support different substrate conversion pathways and a major role of Archaea beyond methanogenesis among the studied digesters.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"126 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136102581","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}

Andrew Ramsburg","doi":"10.1089/ees.2023.0064","DOIUrl":"https://doi.org/10.1089/ees.2023.0064","url":null,"abstract":"The biotransformation of atenolol, sotalol, and metoprolol by mixed culture denitrifying communities was examined as a function of carbon availability and pharmaceutical concentration to explore the possible roles of cometabolism and direct substrate utilization. Sotalol and metoprolol were not found to be transformed. A matrix of conditions explored the biotransformation of water resource recovery facility relevant (25 μg/L) and chemical oxygen demand (COD)-equivalent (10–100 mg/L) atenolol concentrations in batch reactors (1 L) containing 25 mg-N/L nitrate. Carbon (MicroC® 2000) conditions included Nonlimiting (COD:N ratio >10), Partially Limiting (COD:N ratio = 2–3), and Limiting (COD:N ratio <1). Reactors without atenolol served as denitrification control experiments. Results suggest that atenolol did not appreciably influence nitrate reduction. The extent of atenolol degradation was independent of carbon availability. In the experiments conducted in the μg/L range, 30–40% biotransformation was observed. Scant degradation at higher concentrations suggested that direct utilization of the pharmaceutical was either unlikely or occurring slowly and independent of the pharmaceutical concentration. Process-based modeling using the Activated Sludge Model framework assessed denitrification across carbon availability conditions and incorporated three individual pharmaceutical biotransformation modeling strategies: (1) direct metabolism model; (2) cometabolic model, and (3) biotransformation kinetic model. Results suggest that there was insufficient evidence to suspect direct metabolism meaningfully contributed to the reduction in atenolol concentration. The cometabolic process-based model, including both growth and nongrowth-linked rate coefficients offered the best model performance, although growth-linked cometabolism was limited and not readily apparent across all experiments (growth-linked transformation coefficient <0.4 g-atenolol·g-COD−1). Thus, the biotransformation kinetic model is favored for monitoring and forecasting biotransformation in larger-scale systems because use of the parsimonious model (rate coefficient of 7 mg-atenolol·g-COD−1·d−1) resulted in only modest performance reductions. The biotransformation model represents an improvement over pseudo first-order models as it is a mixed-order kinetic model that is linked to transient biomass conditions.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"201 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135510078","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}
