Retention and Distribution of 1-Naphthol and Naphthol Polymerization Products on Surface Soils
Publisher: American Society of Civil Engineers
Abstract: Sorption and extractability of naphthol and naphthol polymerization products (NPP) were evaluated in two surface soils. NPP were generated by the addition of horseradish peroxidase and
Case Studies Can Fill a Critical Need in Environmental Engineering Education
Publisher: American Society of Civil Engineers
Sorption of Tertiary Butyl Mercaptan to Indoor Materials in Contact with Air or Water
Publisher: American Society of Civil Engineers
Abstract: This study reports sorption of the malodorant 2-methyl-2-propanethiol, commonly known as tertiary butyl mercaptan (TBM), to selected indoor materials. The phase distribution of TBM in gas-solid and aqueous-solid systems ...
Occurrence and Degradation of Estrogenic Nonylphenol and its Precursors in Northeast Kansas Wastewater Treatment Plants
Publisher: American Society of Civil Engineers
Abstract: Estrogenic nonylphenol polyethoxylates (NPnEOs) constitute an important class of nonionic surfactants that find wide use in industrial and domestic cleaning products. These chemicals can undergo partial biotransformation ...
Luminol-Based Enhanced Chemiluminescence Assay for Quantification of Peroxidase and Hydrogen Peroxide in Aqueous Solutions: Effect of Reagent pH and Ionic Strength
Publisher: American Society of Civil Engineers
Abstract: The effect of reagent pH and ionic strength was evaluated on the horseradish peroxidase (HRP)-luminol-
Student Learning in a Multidisciplinary Sustainable Engineering Course
Publisher: American Society of Civil Engineers
Abstract: An existing multidisciplinary course on sustainable engineering in developing societies was expanded to include sustainability issues and challenges faced in the developed world. The new course consisted of independent ...
Soil Washing and Biotreatment of Petroleum‐Contaminated Soils
Publisher: American Society of Civil Engineers
Abstract: Soil washing was evaluated in combination with biological treatment as a decontamination technology for petroleum‐contaminated soils. The bench‐scale soil washing system utilized to clean the soils also fractionated the ...
Pilot-Scale Evaluation of Denitrification Drainage Bioreactors: Reactor Geometry and Performance
Publisher: American Society of Civil Engineers
Abstract: Denitrification drainage bioreactors are emerging as an innovative practice to address water quality concerns stemming from nitrate leaching from drained agricultural lands. Although installation of these systems has begun ...
Modeling and Calibration of Drainage Denitrification Bioreactor Design Criteria
Publisher: American Society of Civil Engineers
Abstract: Design methods for agricultural drainage denitrification bioreactors must be optimized for these novel systems to provide maximized water quality improvement. The objective of this paper was to further develop science-based ...
