Framework for Evaluating the Impact of Water Chemistry Changes in Full-Scale Drinking Water Distribution Networks on Lead Concentrations at the Tap
(ASCE, 2020)Release of lead (Pb) in drinking water from lead service lines has been extensively studied in single pipes, and the importance of water chemistry has been reported. However, the impact of variations in water chemistry ... -
Sensor Placement Optimization Software Applied to Site-Scale Methane-Emissions Monitoring
(ASCE, 2020)Advances in sensor technology have increased our ability to monitor a wide range of environments. However, even as the cost of sensors decline, only a limited number of sensors can be installed at any given site. The ... -
Efficient Removal of Metronidazole by the Photo-Fenton Process with a Magnetic Fe<sub>3</sub>O<sub>4</sub>@PBC Composite
(ASCE, 2020)Fe3O4-coated pretreated biochars (Fe3O4@PBC) were prepared for the first time by a Fe(III)-ethanol solution impregnation-calcination method. When photo-Fenton catalysts were used, their effectiveness in removing metronidazole ... -
Hydrologic Comparison of Prescriptive and Water Balance Covers
(ASCE, 2020)The objective of this study is to compare the hydrology of prescriptive and water balance cover designs for Larimer County Landfill in Colorado via hydrologic models parameterized from laboratory-measured testing of ... -
Remediation of Cd Contaminated Soil in Microbial Fuel Cells: Effects of Cd Concentration and Electrode Spacing
(ASCE, 2020)A microbial fuel cell (MFC) was constructed to remediate cadmium (Cd) contaminated soil, and the effects of Cd concentration (0, 5, 20, and 100 mg/kg) and electrode spacing (3, 6, and 9 cm) on reactors were studied. ... -
Application of Cyanobacterial Consortium to Remove Ammoniacal-N, Phenol, and Nitrate from Synthetic Coke-Oven Wastewater as Tertiary Treatment
(ASCE, 2020)This investigation focused on phycoremediation of pollutants from synthetic coke-oven wastewater using a cyanobacterial consortium of Leptolyngbya sp. and Planktothrix sp., and biomass production. Lethal dose analysis was ... -
Kinetic Analysis and Treatment of Compost Leachate Using Data from a Plant-Scale Hybrid Anaerobic Reactor
(ASCE, 2020)Compost leachate is one of the most strongly polluting wastewaters, which is found in significantly large amounts. The major objective of this research was to study the biological treatment of compost leachate in an ... -
Preparation of Flower-Like Ag@AgBr/ZnO Photocatalyst and Photocatalytic Degradation Mechanism on Cefuroxime Sodium
(ASCE, 2020)An Ag@AgBr/ZnO modified photocatalyst was prepared by a simple one-step hydrothermal method. The composites were well characterized by various analytical techniques, and the influence of an Ag@AgBr/ZnO system on the ... -
Effect of Biomass and Operating Condition on Biodegradation Capacity of a Mix of Pharmaceuticals (Carbamazepine, Ibuprofen, and Ciprofloxacin) in a Membrane Bioreactor
(ASCE, 2020)There is no existing applicable law that regulates compounds of emerging concern (CECs), so they remain a global concern because they are easily taken up by organisms. Because of the current need, different processes have ... -
Aqueous Phosphate Removal and Electricity Production Using an Iron–Air Fuel Cell
(ASCE, 2020)Phosphorus (P) surplus is a key factor in water eutrophication, and aqueous phosphate removal is a concern. In this study, ferrous ions (Fe2+) were generated in situ by iron–air fuel cells and were used in the removal of ... -
