Assessment of the Potential Functional Diversity of the Bacterial Community in a Biofilter
(University of Waterloo, 2006)A biofilter removes biodegradable contaminants from air by passing it through a biologically-active packed bed. The microorganism community is of fundamental interest but has been the focus of few studies. This work ... -
Behaviour of Oxygenates and Aromatic Hydrocarbons in Groundwater from Gasoline Residuals
(University of Waterloo, 2007-01-23)ABSTRACT This study focuses on the dissolution and near-source attenuation of oxygenated gasoline hydrocarbons in groundwater from two gasoline residual sources: one containing gasoline with 9.8% methyl tert butyl alcohol ... -
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, ... -
Effect of Fuel Ethanol on Subsurface Microorganisms and its Influence on Biodegradation of BTEX Compounds.
(University of Waterloo, 2000)Ethanol is used as fuel in neat form in some countries (Brazil and India) or blended with gasoline (Europe, Canada and the United States). The benefits of ethanol use include octane enhancement, a cleaner environment and ... -
Layer-by-layer Self-assembly Membranes for Solvent Dehydration by Pervaporation
(University of Waterloo, 2013-12-09)In this study, polyelectrolyte membranes were prepared by layer-by-layer self-assembly on top of an interfacially polymerized polyamide substrate, and these thin-film-composite membranes were studied for pervaporative ... -
Optimizing Solvent Extraction of PCBs from Soil
(University of Waterloo, 2009-08-04)Polychlorinated biphenyls (PCBs) are carcinogenic persistent contaminants. Although their manufacturing in North America ceased in the late 1970s, their high heat resistance made their use widespread over their production ...
