However, poor maintenance can lead to sediment buildup, increasing the risk of urban flooding and downstream water pollution. This study investigates sediment characteristics and accumulation in CBs and proposes an evidence-based cleaning strategy through a field study in Calgary, Alberta, across 28 CBs in 2023 and 2024. The results indicate that sediment accumulation rates and metal concentrations vary with land use, being higher in CBs near houses and roads than in those near grassed areas. Sediment composition and metal concentrations exhibit vertical stratification, with smaller particles (i.e., clay and silt) having higher metal concentrations in the bottom layers, while larger particles form an armoring layer at the surface. This segregation, together with the armoring layer, helps to protect metal-rich small particles from scouring during storm events, potentially reducing the release of pollutants. Sediment scour analysis reveals a sharp increase in scour when the free depth ratio - the distance from the sediment surface to the CB lead (i.e., outlet pipe) invert divided by the CB diameter - falls below 0.2. Therefore, CBs should be cleaned when this ratio approaches 0.2.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"93 3","pages":"346-367"},"PeriodicalIF":2.8,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146182743","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 incorporation of AC markedly accelerated TCE oxidation by enriching contaminants within its microenvironment and promoting reactive species (ROS) generation. The optimal PS/iron/TCE molar ratios with 0.5 g L-1 AC were 20/10/3 for the PS/ZVI/TCE system and 20/60/3 for both PS/FeS/TCE and PS/FeS2/TCE systems. Scavenging and electron paramagnetic resonance (EPR) analyses identified hydroxyl radicals (HO•), sulfate radicals (SO4-•), and singlet oxygen (1O2) as the dominant ROS responsible for TCE degradation. All three systems maintained over 90% removal efficiency across a wide pH range (3-9). Anion interference tests revealed that bicarbonate (HCO3-) strongly inhibited ROS formation, while other anions had minor effects. Experiments using actual groundwater confirmed the robustness of the AC-iron systems, which achieved efficient degradation of chlorinated alkenes, while exhibiting limited activity toward saturated chlorinated alkanes. Overall, this research highlights the synergistic role of AC and iron-based materials in PS activation and provides valuable insights into selective CHC degradation in a complex groundwater environment.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"93 4","pages":"520-533"},"PeriodicalIF":2.8,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147322325","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}

Therefore, facultative microbial strains capable of both heterotrophic nitrification-aerobic denitrification and phosphorus accumulation are highly desirable, as they can enhance nutrient removal efficiency by maximizing carbon utilization within a single biological process. In this study, a multifunctional bacterium, Pseudomonas putida S3, was isolated from excess sludge collected from a municipal wastewater treatment plant. Batch experiments optimized their nutrient removal, with sodium citrate as the preferred carbon source, ammonium chloride as the nitrogen source, a C/N ratio of 6, and a nitrogen-to-phosphorus ratio of 15. Under aerobic conditions, strain S3 exhibited excellent simultaneous nitrogen and phosphorus removal. The observed removal of ammonia nitrogen, reaching 73.33%, together with a simultaneous 71.53% decrease in total nitrogen within 48 h under aerobic conditions, supports heterotrophic nitrification and suggests potential aerobic denitrification. Moreover, S3 achieved complete removal of phosphorus from the aqueous phase under aerobic conditions, accompanied by the intracellular formation of metachromatic granules. These findings highlight strain S3 as a promising microbial candidate for advanced treatment of low C/N wastewater and provide a theoretical basis for resource-oriented utilization of excess sludge.","PeriodicalId":23653,"journal":{"name":"Water Science and Technology","volume":"93 3","pages":"332-345"},"PeriodicalIF":2.8,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146182798","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}

Membrane fouling is a key challenge to the practical application of SHSO in cleaning oily wastewater. This study designed and meshed a hybrid system that integrates SHSO membrane filtration with gravity separation via a hydrocyclone using ANSYS Fluent. The hydrocyclone performs a gravity separation on the initially produced water to break down and evict larger oil droplets from the mixture before passing it through the SHSO membranes. This assists significantly in reducing the fouling time of the SHSO membrane, hence contributing to the improved filtration efficiency of the membrane. The SHSO membranes developed were able to separate oil from water at an efficiency ranging from 97.55 to 99.65% for a membrane with one fluid outlet and 99.99% in the case of dual membranes with two fluid outlets. The hybrid system resulted in high separation efficiency and high anti-fouling abilities.
