Evaluation of fuel ethanol releases in a pilot-scale aquifer tank: Source dynamics, NAPL migration and microbial community response
Ethanol is playing a key role in current discussions on energy, agriculture, taxes and the environment. This work addresses the potential environmental impacts and behavior of subsurface fuel-ethanol releases. A continuous-flow ...
Settling characteristics of fractal aggregates
The settling velocity of aggregates found in engineered water and wastewater treatment facilities are usually assumed to follow Stokes' law. These particles, however, are typically porous and may be fractal in nature. As ...
Effect of recirculation on the performance of a trickling filter
Abstract Not Available.
Bacteria and fullerene: The microbial response to fullerene water suspensions
The current nanotechnology boom necessitates timely research into the health and environmental impacts of nanomaterials to enhance their eco-responsible manufacture, use, and disposal. Using the water-insoluble C60 as a ...
Kinetics of core material dissolution in the presence of inhibitors for application in geologic carbon sequestration
With increased attention on rising carbon dioxide levels, carbon capture and sequestration (CCS) has become a commonly proposed solution. CCS has been studied for several decades, but is being researched more and more ...
The Water Footprint of Fuel Ethanol
Biofuels (Le., biomass-derived fuels) play a key role in discussions in the United States about energy security, agriculture, taxes and the environment. Although their potential to reduce our dependence on foreign oil and ...
Effect of calcium (II) and iron (II) on the precipitation of calcium carbonate and iron carbonate solid solutions and on scale inhibitors retention
Mineral scale formation is important to many areas of science and engineering, from drinking water treatment to oceanography to oil and gas production. In some cases mineral deposition is beneficial, as in water treatment ...
1D and 2D Methods for Modeling Floodplains under Storm Surge Conditions
This study evaluates a 1D and a 2D method for analyzing the combined effect of inland rainfall and hurricane-induced storm surge on a coastal floodplain. Horsepen Bayou near Clear Lake, southeast of Houston, Texas is ...
The Impact of Palustrine Wetland Loss on Flood Peaks: An Application of Distributed Hydrologic Modeling in Harris County, Texas
This study uses a distributed hydrologic model to assess the impact of wetland loss on flood peaks. There is large agreement among hydrologists that wetlands have significant flood-mitigation potential. However, the lack ...
Transport of carbon nanomaterials in natural rocks and their application in oilfield exploration
This report studies the application of carbon nanomaterials as a novel type of tracer in detection of residual oil. The carbon nanomaterials studied include oxidized carbon black (OCB) coated with different molecular weight ...
