This study investigated the hydraulic characteristics of stormwater sumps and their design optimization for sediment retention using physical experiments. Particle image velocimetry was utilized to measure the flow field, and the use of internal structures was investigated for improving solids retention. Results indicate that these internal structures can significantly improve the sediment removal efficiency of suspended solids with an average size of 125 μm, resulting in an efficiency improvement of 20-30%. Additionally, a modified Péclet number was proposed to more accurately evaluate the sediment removal efficiency of stormwater sumps, and recommendations were provided for further improving and optimizing sump design. This study provides insights into the hydraulic characteristics of stormwater sumps and has important implications for optimizing and designing particle removal systems for various industrial and environmental applications.

Arsenic-contaminated groundwater is widely used in agriculture. To meet the increasing demand for safe water in agriculture, an efficient and cost-effective method for As removal from groundwater is urgently needed. We hypothesized that Fe (oxyhydr)oxide (FeOOH) minerals precipitated in situ from indigenous Fe in groundwater may immobilize As, providing a solution for safely using As-contaminated groundwater in irrigation.

Mycoremediation is a biological treatment approach that relies on fungi to transform environmental pollutants into intermediates with lower environmental burden. Basidiomycetes have commonly been used as the target fungal phylum for bioaugmentation in mycoremediation, however this phylum has been found to be unreliable when used at scale in the field. In this study, we isolated, characterized, and identified potential polycyclic aromatic hydrocarbon (PAH) degrading fungal isolates from creosote-contaminated sediment in the Elizabeth River, Virginia.

Manganese (Mn), abundant in the Earth's crust, can act as an oxidant or a reductant for diverse nitrogen biotransformation processes. However, the functional microorganisms and their metabolic pathways, as well as interactions, remain largely elusive. Here, a microbial consortium was enriched from a mixture of freshwater sediments and activated sludge by feeding ammonium, nitrate and Mn(II), which established manganese-driven co-removal of nitrate and ammonium with removal rates of 5.

The ecosystem regulating services from tidal flats, such as removal of organic pollutants, provided by natural tidal flats are being increasingly recognized, yet quantitative evaluation remains limited. Here we evaluated a nationwide capacity of natural purification in tidal flats. Using in situ sediments from five along the Korean coast (Incheon, Gunsan, Sinan, Gwangyang, and Busan), we applied a mesocosm system informed by 18 years of riverine monitoring data from national surveys.

The extensive agricultural use of the fungicide difenoconazole (DIF) and its associated toxicity increasingly damage ecosystems and human health. Thus, an urgent need is to develop environmentally friendly technological approaches capable of effectively removing DIF residues. In this study, strain A-3 was isolated for the first time which can degrade DIF efficiently.
