Degradation of Phenolic Compounds Using Laccase or Peroxidase Enzymatic Treatment
(2010-07-16)
To remove ammonia from wastewater most refineries use biological treatment employing suspended biomass because there is no secondary pollutant. The main purpose of biological treatment is to accelerate the oxidation process ...
The Effects of Land Cover, Climate, and Urbanization on Groundwater Resources in Dauphin Island
(2011-11-21)
The effects of land cover change, climate change, and population growth on the groundwater resources of a barrier island were explored in this study. The relationship between land cover and groundwater recharge was studied ...
In situ Degradation of Trichloroethylene in Soil and Groundwater with Stabilized Zero Valent Iron Nanoparticles and Catalytic Hydrodechlorination with Supported Palladium Nanoparticles
(2012-05-03)
Chlorinated solvents, such as trichloroethylene (TCE), are potent carcinogens and have been found in soil and groundwater at thousands of National Priorities List sites in the U.S. To facilitate in-situ chlorinated solvents ...
The Feasibility of Using Alternative Fuels to Produce Portland Cement
(2012-02-08)
The production of cement involves a combination of numerous raw materials,
strictly monitored system processes, and temperatures on the order of 1500 °C.
Immense quantities of fuel are required for the production of ...
Development of a Biennial Review Procedure for Updating Liquidated Damage Rates Used in Construction Contracts
(2008-09-09)
This research effort sought to develop statistically justifiable means for developing a schedule of liquidated damage (LD) rates to be adopted by the Alabama Department of Transportation (ALDOT). The procedure outlined ...
The Utilization of Alternative Fuels in the Production of Portland Cement
(2008-09-09)
The production of portland cement converts many different raw materials into clinker, in the presence of temperatures on the order of 1,500 degrees Celsius. Historically, nonrenewable fossil fuels have been used to maintain ...
Evaluating Water Quality Impacts of Alternative Management Practices through Development of a BMP Database
(2008-09-09)
Agriculture and forestry are two important industries in the State of Alabama, and each is historically known to cause nonpoint source (NPS) pollution problems. Currently, the U.S. Environmental Protection Agency (USEPA) ...
Potential Negative Effects of Adding Phosphate-Based Fertilizers to Lead In Metal-Contaminated Soils
(2008-09-09)
The potential negative effects of adding phosphate amendments for lead (Pb) remediation in Pb-contaminated soils were studied using column and batch experiments. Soils contaminated with high levels of lead as well as ...
Evaluation of Erosion and Sediment Control Best Management Practices: Use of Silt Fence Tieback Systems and Anionic Polyacrylamide on Highway Construction Sites
(2008-09-09)
Every year the construction process exposes millions of acres of earth to the elements of wind, rain, and snow. This greatly increases the potential for erosion; therefore, the need for efficient erosion and sediment ...
Immobilization of Mercury Using Iron Sulfide Minerals
(2008-09-09)
Mercury is a pervasive pollutant that has caused environmental and health problems throughout the world. Numerous industries including coal-fired power plants and chlor-alkali plants have discharged mercury into the ...
