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 ...
