Cellular Automata-Based Mechanistic Model for Analyzing Microbial Regrowth and Trihalomethanes Formation in Water Distribution Systems
(ASCE, 1/1/2021)This paper describes a novel cellular automata-based mesoscale multispecies reactive-transport (CA-MSRT) model for predicting microbial regrowth and trihalomethanes (THMs) formation in water distribution systems (WDSs) ... -
Effects of Biochar on Methane Oxidation and Properties of Landfill Cover Soil: Long-Term Column Incubation Tests
(ASCE, 1/1/2021)Landfill gas poses significant risk to global climate change. Landfill gas is composed of very high concentrations of methane (CH4), nearly 50% by volume. The present study investigates the use of biochar amendment to silty ... -
Oxidation Macrokinetics of Sulfite in the Zinc-Based Wet Flue Gas Desulfurization Process
(ASCE, 2/1/2021)The zinc oxide method is one of the most popular flue gas desulfurization processes, especially for the control of low-content sulfur dioxide. In this process, zinc sulfite can be oxidized to form a soluble zinc sulfate, ... -
Efficient Adsorption of Tetracycline Using Cu+-Modified SBA-15 and Its Adsorption Mechanism
(ASCE, 1/1/2021)Cu+-modified SBA-15 (Cu+/SBA-15, SBA-15 refers well-ordered hexagonal mesoporous silica) was prepared for adsorption of tetracycline (TC) by the pH adjusting reduction method. Some Cu+ species (Cu2O) are aggregated on the ... -
System for Identifying Ships Using High-Sulfur-Content Fuel Oil in Port Waters
(ASCE, 2/1/2021)This study develops a system named Wuhan University of Technology Intelligent Tracer (WUT-iTracer) for identifying ships using high-fuel-sulfur-content (FSC) fuel oil in port waters. The system integrates a land-based ... -
Absorption of SO2 from a Gas-Air Mixture by Solutions Containing Iron Compounds
(ASCE, 12/1/2020 )The chemisorption of sulfur(IV) oxide (SO2) from air by natural aqueous media containing iron (Fe) ions is a current area of research interest. At the same time, studies of SO2 absorption from gases with higher concentrations ... -
SARS-CoV-2 in Detroit Wastewater
(ASCE, 11/1/2020 )Untreated wastewater samples were collected from the Great Lakes Water Authority (GLWA) Water Resource Recovery Facility (WRRF) located in southeast Michigan between April 8 and May 26, 2020. The WRRF is the largest ... -
Disinfection of Fecal Sludge Using Solar Thermal Water Heating: Sludge Management Option for Developing Countries
(ASCE, 12/1/2020 )This study investigates a solar thermal water heating system that is effective in drying and disinfecting fecal sludge (FS) and recovering nutrients and water resources that happen to have fertility values for agricultural ... -
Carbon-Dioxide and Hydrogen-Sulfide Removal from Simulated Landfill Gas Using Steel Slag
(ASCE, 12/1/2020 )Municipal solid waste landfills are a source of major greenhouse gases such as methane (CH4) and carbon dioxide (CO2) and emit a trace amount of hydrogen sulfide (H2S). Recently, steel slag has extensively been used for ... -
Erosion on Cohesive Deposition in Storm Sewers
(ASCE, 12/1/2020 )Erosion of sediment deposition in storm sewers is dominated by the bed shear stress and the deposition characteristics. A laboratory study investigated the critical shear stress and erosion processes for different types ... -
