Biochar as a Carrier of Struvite Precipitation for Nitrogen and Phosphorus Recovery from Urine
(American Society of Civil Engineers, 2018)Struvite precipitation is a promising approach to recover nitrogen (N) and phosphorus (P). However, poor solid−liquid separation of struvite precipitation crystallization can significantly decrease resource recovery ... -
Effect of Quality Electrolyte Fluid on Removing MTBE from a Clay Soil Using Electrokinetic Technique
(American Society of Civil Engineers, 2018)Methyl tertiary butyl ether (MTBE) is a chemical product and the most commonly used gasoline oxygenate. It is characterized as a pollutant for soil and water that has effects on human health. Research on the remediation ... -
Effect of Lake Nitrogen Fixation on Watershed Export under Loading Reduction Scenarios
(American Society of Civil Engineers, 2018)Coastal eutrophication is an important problem, and nitrogen input from the watershed is a primary cause. Consequently, management efforts often focus on lowering watershed N export by reducing the N loading (e.g., from ... -
Vegetated Swales for Managing Stormwater Runoff from Secondary Roads
(American Society of Civil Engineers, 2018)Secondary roads play an important role for connecting local communities to principal county and state highways and, in some cases, may account for a large proportion of the state-maintained road systems. Existing swales ... -
Preparation and Characterization of Polyacrylonitrile/Aluminum Oxide Nanofiber Adsorbent Modified with 2-Amino-3-Methyl-1-Hexanethiol for the Adsorption of Thorium (IV) Ion from Aqueous Solution
(American Society of Civil Engineers, 2018)In this study, a novel polyacrylonitrile/aluminum oxide (PAN/Al−ONPs) nanofiber adsorbent modified with 2-amino-3-methyl-1-hexanethiol (AMH) was synthesized by a combination of hydrothermal and electrospinning and evaluated ... -
Degradation Kinetic and Remediation Effectiveness of 1,4-Dioxane-Contaminated Groundwater by a Sono-Activated Persulfate Process
(American Society of Civil Engineers, 2018)The well-known biorefractory organic material 1,4-Dioxane (1,4-D) is difficult to degrade in groundwater by classical treatment processes. The sono-activated persulfate process was applied to remediate 1,4-D-contaminated ... -
Pilot-Scale Polyhydroxyalkanoate Production from Paper Mill Wastewater: Process Characteristics and Identification of Bottlenecks for Full-Scale Implementation
(American Society of Civil Engineers, 2018)In this study, the suitability of paper industry wastewater for production of polyhydroxyalkanoate (PHA) was investigated in a pilot reactor in an industrial setting. The pilot plant was designed as a three-step process ... -
Catalytic Removal of Remazol Brilliant Blue R by Manganese Oxide Octahedral Molecular Sieves and Persulfate
(American Society of Civil Engineers, 2018)In this paper, manganese oxide octahedral molecular sieves (OMS-2) as a novel catalyst were used in activation of persulfate (PS) for Remazol Brilliant Blue R (RBBR) dye removal. The dye removal efficiencies of different ... -
Impact of Biosolids on Indigenous Soil Denitrifying Bacteria
(American Society of Civil Engineers, 2018)A major drawback to land application of biosolids is the potential environmental release of nonregulated organic contaminants that accumulate in the biosolids during the wastewater treatment process. In particular, because ... -
