Gravimetric and Number Distributions of Urban PM Residuals from Urban Maintenance Practices
(ASCE, 2021-10-30)Particulate matter (PM) recovery from street sweeping (SS), catch basin (CB), and unit operation (UO) is essential for sustainability of these urban hydrologic functional units (HFUs). PM inventory in HFUs is of increasing ... -
Sorption and Release of Nickel and Zinc Using a Mixed-Algae Community Collected from a Mine Drainage Passive Treatment System
(ASCE, 2021-11-25)Mine water from upwellings in Commerce, Oklahoma is treated by the Mayer Ranch Passive Treatment System (MRPTS) to remove contaminants. Nickel [Ni(II)] and zinc [Zn(II)], which are toxic to both plants and animals when ... -
Desorption Isotherms for Poly- and Perfluoroalkyl Substances in Soil Collected from an Aqueous Film-Forming Foam Source Area
(ASCE, 2021-10-27)Bench-scale experiments were performed to evaluate poly- and perfluoroalkyl substance (PFAS) desorption from vadose zone soils collected at a site historically impacted with aqueous film-forming foam (AFFF). A sequential ... -
Fe3+-NTA-Catalyzed Homogenous Fenton-Like Degradation of Trichloroethylene in Groundwater at Natural pH (∼8.0): Efficacy, By-Products, and H2O2 Utilization
(ASCE, 2021-10-21)The ferric-nitrilotriacetate (Fe3+-NTA)-catalyzed homogenous Fenton-like reaction (i.e., Fe3+-NTA/H2O2) has received increasing interest for environmental applications, but its potential in degrading trichloroethylene ... -
Impact of Inherent Magnesium in Biochar for Phosphate Removal from Reclaimed Water Streams
(ASCE, 2021-12-11)In water treatment processes, the use of biochars has risen due to their relative abundance, sustainability, and low cost compared with conventional technologies. The objective of this work was to investigate the physical ... -
The Influence of Pollution Sources on CH4 and CO2 Emissions in Urbanized Wetland Areas of a Tropical Reservoir, Southeast, Brazil
(ASCE, 2021-10-18)Wetlands play an important role in biodiversity protection and ecosystem services provision but are susceptible to continuous degradation from the urban environment. In this study, objectives have been made to evaluate the ... -
Application of Micro–Nano Bubbles to Improve the Performance of Reverse-Osmosis Membrane against the Gypsum Scaling
(ASCE, 2021-10-27)The present study investigated the effects of air micro–nanobubbles (AMNBs) on calcium sulfate dehydrate (gypsum) scaling over a reverse-osmosis (RO) membrane in a lab-scale plate-and-frame module processing brackish water. ... -
Assessing the Scale Dynamics of the Rainfall Retention of Green Roofs in a Subtropical Climate
(ASCE, 11/1/2021)Various studies have provided insights about how green roof rainfall retention capacity is affected by factors including typology, vegetation, growing media’s physical-chemical-biological properties, drainage system, climate ... -
The Water Quality Improvement through Two Pollutant Load Allocation Methods in Gehu Lake, China
(ASCE, 12/1/2021)Due to many industrial and domestic pollution sources gathered around Gehu Lake and the lack of effective reduction measures, the ammonia nitrogen and total phosphorus in a large area of the lake exceed the standard. In ... -
