Effect of ethanol on BTEX biodegradation in aerobic aquifer systems
(University of Waterloo, 2008-01-04)Ethanol can affect the biodegradation of gasoline hydrocarbons in groundwater. High concentrations of ethanol can be toxic to subsurface microorganisms that are otherwise capable of degrading hydrocarbons, such as benzene, ... -
Fate and Transport of Naphthenic Acids in Glacial Aquifers
(University of Waterloo, 2004)Naphthenic acids (NAs) are carboxylated alkanes and cycloalkanes concentrated in wastewater during oil sands processing. The general chemical formula is C{n}H{n+Z}O{2}, where n represents the number of carbon atoms and ... -
Numerical Simulation of Hydrocarbon Fuel Dissolution and Biodegradation in Groundwater
(University of Waterloo, 2000)The behaviour of hydrocarbon fuels in contaminated groundwater systems is studied using a multicomponent reactive transport model. The simulated processes include residual NAPL dissolution, aerobic and anaerobic ... -
The Physical Mechanisms of Microbiological Cellular Transport, Storage, and Metabolism of Aromatic Hydrocarbon-Degrading Soil Microbiota
(University of Waterloo, 2021-06-01)The Monod bioreaction equation, though justified from extensive practical use, has been found to have limited mechanistic basis (Enouy, Walton, et al., 2021). To attempt to gain a biological mechanistic representation of ... -
Remediation of Pentaerythritol Tetranitrate (PETN) Contaminated Water and Soil
(University of Waterloo, 2007-11-28)Pentaerythritol tetranitrate (PETN), a nitrate ester, is widely used as a powerful explosive and is classified as a munitions constituent of great concern by DoD in U.S.A. It is an environmental concern and poses a threat ...
