Input/output energy analysis of regional water pollution control

Creator:: Heggen, Richard J.
Abstract:: Two strategic approaches to water quality control in Oregon's Willamette River are presently being utilized: point source treatment and flow augmentation. Dry weather releases from reservoirs are for authorized purposes other than water quality. Reservoirs can participate in pollution control by summer flow augmentation where authorized water resource objectives (flood...

Bacterial toxicity and metabolism of three hydrazine fuels

Creator:: Kane, Donald A.
Abstract:: Hydrazine based fuels are used by the Air Force for the Titan II and Minuteman III missiles and the F-16 aircraft and by the National Aeronautics and Space Administration for propulsion systems and the Space Shuttle Program. These uses represent significant production, transportation and storage of these fuels, and, as...

The geochemical partitioning and bioavailability of trace metals in marine sediments

Creator:: Oakley, Stewart M.
Abstract:: Trace metals in the aquatic environment are generally concentrated on the surface of solid geochemical phases which eventually become incorporated into estuarine and marine sediments. The mechanism of trace metal concentration is believed to be adsorption with various geochemical phases such as hydrous metal oxides, clays, and organic matter. Metals...

The effect of dissolved oxygen concentration on the activated sludge process

Creator:: Swanson, Gregory R.
Abstract:: Since the introduction of pure oxygen activated sludge systems in the late 1960's, proponents have claimed several advantages resulting from the elevated dissolved oxygen (DO) levels maintained. However, numerous comparative studies have failed to produce a consensus of professional opinion regarding the validity of these claimed advantages. The purpose of...

Substratum-aerated-biofilm reactor for treatment of carbonaceous and nitrogenous wastewaters

Creator:: Abdel-Warith, Ahmed S.
Abstract:: This study involves the development of a biofilm reactor that supports growth of a deep biofilm on a gas permeable membrane. The reactor solution is not aerated, and oxygen is supplied through the membrane. The reactor is termed a substratum-aerated-biofilm reactor or SAB. With adequate concentrations of electron-donors and electron-acceptors,...

Effects of substrate interactions, toxicity, and bacterial response during cometabolism of chlorinted solvents by nitrifying bacteria

Creator:: Ely, Roger L.
Abstract:: Cometabolic biodegradation processes, important for bioremediation of hazardous waste sites, are not well understood and have not been modeled thoroughly. Toxic effects and bacterial responses to toxicity may change intracellular enzyme levels, rendering traditional enzyme kinetics models inappropriate. This document presents a novel cometabolic enzyme kinetics model that incorporates enzyme...

Cometabolic degradation of polycyclic aromatic hydrocarbons (PAHs) and aromatic ethers by phenol- and ammonia-oxidizing bacteria

Creator:: Chang, Soon Woong
Abstract:: Cometabolic biodegradation processes are potentially useful for the bioremediation of hazardous waste sites. In this study the potential application of phenol-oxidizing and nitrifying bacteria as "priming biocatalysts" was examined in the degradation of polycyclic aromatic hydrocarbons (PAHs), aryl ethers, and aromatic ethers. We observed that a phenol-oxidizing Pseudomonas strain cometabolically...

Biodegradation of methyl tert-butyl ether (MTBE) and its breakdown products by propane and iso-pentane grown Mycobacterium vaccae and Graphium sp. : cometabolism, inhibition, kinetics, and modeling

Creator:: Martínez-Prado, Maria Adriana
Abstract:: Mycobacterium vaccae JOB5 and Graphium sp. were studied to evaluate their ability to cometabolize methyl tert-butyl ether (MTBE) and its metabolites after growth on two different alkanes, propane and iso-pentane. Both cultures were capable of cometabolizing MTBE and the metabolites, tert-butyl formate (TBF) and tert-butyl alcohol (TBA). MTBE, TBF, and...
