RISMotivations of Program Partners for Environmental Sustainability and Persistence of Benefits
Publisher: American Society of Civil Engineers
Abstract: It is becoming more common for sustainability-related engineering classes to engage in various forms of service and project learning activities that provide assistance to partners. However, few efforts have examined the ...
Relative Impact on GAC Usage Rates of Operating Strategies for Treatment of Contaminated Groundwater
Publisher: American Society of Civil Engineers
Abstract: The former Nebraska Ordnance Plant has groundwater contaminated with a mixture of trichloroethylene (TCE) and the high explosive RDX that is treated in a system of eight granular activated carbon (GAC) contactors. A ...
GAC Contactor Design for NOM Removal: Implications of EBCT and Blending
Publisher: American Society of Civil Engineers
Abstract: Many drinking water utilities may choose to use granular activated carbon (GAC) to remove disinfection by-product precursors from their water to comply with proposed U.S. Environmental Protection Agency rules. Activated ...
Pollutant Load Estimates Using Regression Models with In-Stream Measurements
Publisher: American Society of Civil Engineers
Abstract: A continuous in-stream water quality measurement (CWQ) study was carried out in two Lincoln, Nebraska urban watersheds. Discrete stormwater samples were collected at the study sites during 17 storm runoff events over a ...
Disinfection By-Product Precursor Adsorption as Function of GAC Properties: Case Study
Publisher: American Society of Civil Engineers
Abstract: Four different granular activated carbons (GACs) were tested at the bench scale for the adsorption of disinfection by-product (DBP) precursors and were found to be spent at different rates for the Lincoln (Nebraska) water ...
Pollutant Load Estimates Using Regression Models with In-Stream Measurements
Publisher: American Society of Civil Engineers
Abstract: A continuous in-stream water quality measurement (CWQ) study was carried out in two Lincoln, Nebraska urban watersheds. Discrete stormwater samples were collected at the study sites during 17 storm runoff events over a ...
Niche for Steam Stripping in Treating Dilute SOC-Contaminated Waters
Publisher: American Society of Civil Engineers
Abstract: As regulatory limits for contaminants in air and water become increasingly stringent, interest in steam stripping to remove synthetic organic compounds (SOCs) from industrial waters has increased. To identify situations ...
Intensive Environmental Sustainability Education: Long-Term Impacts on Workplace Behavior
Publisher: American Society of Civil Engineers
Abstract: The University of Nebraska Partners in Pollution Prevention (P3) program has provided a results-oriented intensive sustainability course since 1997. This course focuses on providing students with application tools to promote ...
Framework for Evaluating Sorbent Usage Rate of Various Sorption Column Configurations with and without Bypass Blending
Publisher: American Society of Civil Engineers
Abstract: This study evaluated the system performance in terms of sorbent usage rate (SUR) of single column, two-column parallel, and lead-lag configurations, both with and without bypass blending, based on two normalized parameters ...
Selection among Aqueous and Off-Gas Treatment Technologies for Synthetic Organic Chemicals
Publisher: American Society of Civil Engineers
Abstract: A methodology for selecting the least-cost treatment technology for waters contaminated by organic wastes was developed using performance and cost models. This methodology simplifies the selection of the least expensive ...
