INFLUENCE OF ADSORPTION AND OXYGEN LIMITED BIODEGRADATION ON THE TRANSPORT AND FATE OF A CREOSOTE PLUME: FIELD METHODS AND SIMULATION TECHNIQUES (HYDROCARBON, GROUNDWATER, MODELING, TRACER TEST)
… hydrocarbon contaminated ground water is present and is contained within a large plume of elevated chloride concentrations. This difference in size could be due to two processes: adsorption and biodegradation. A series of field tests and computer simulations were performed to identify which …

Nitrification and denitrification in the activated sludge process
… using influent organics as the carbon source and nitrate as an electron acceptor to see if any oxygen savings could be obtained. The key research tools used were mathematical modeling, computer simulation, the library, and discussions with experienced operating engineers. A mathematical model …

The reduction of bromate in drinking water by activated carbon
… has been studied. Both granular activated carbon and powdered activated carbon have been used to reduce bromate. Solution characteristics which influenced the reduction of bromate during this study include solution pH, initial bromate concentration, ionic strength of the solution, the presence of …

Analysis and control of voltage dynamics in electric power systems
… The thesis is divided into two parts: analysis and control of voltage dynamics. In the analysis section, the interaction of machines dynamics with the dynamics of decentralized load voltage controls, such as ULTC (under load tap changers), is investigated. A detailed reduced-order machine …

Advanced aerobic digestion to optimize pathogen reduction: Staged pre-treatment in aerobic digestion
Land application of biosolids is a desirable solution for smaller communities that utilize aerobic digestion. However, traditional aerobic digestion produces Class B biosolids at best which raises public concern regarding the fate of pathogens following land application. The main goal of this work …
