Anaerobic Biodegradation Of Trichloroethylene With The Addition Of Sugar Using Activated Carbon-Fluidized Beds, Suxan Huang

Dissertations

Anaerobic biodegradation of trichloroethylene (TCE) was carried out in a two-stage granular activated carbon fluidized bed bioreactor. The intermediate products were identified as: dichloroethylene (DCE), vinyl chloride (VC), 1,2-dichloroethane (DCA) and chloroethane (CA). Of the three geometric isomers of DCE, the trans-1,2 dichloroethylene (TDCE) was found to be the most predominant species, The production of DCA suggested a diverted reaction sequence from the conventional sequential reductive dechlorination pathway postulated in the past literature. CA was believed to be a product of VC and/or DCA. The co-substrate glucose was implicated for this reaction specificity. Based on our data and on other's …

Air Stripping Of Volatile Organic Contaminants Using Rotating Disc Contactor, Kai-Ping Hsueh

Dissertations

Previous studies have suggested that the transfer of VOCs to the atmosphere by air stripping may be a convenient and potentially cost-effective method to remove these compounds from the water. A Rotating Disk Contactor (RDC), similarly to other aeration devices, can provide intimate contact between the VOC-bearing water and air. It is believed that under carefully selected operating conditions, the RDC system are more competitive with packed tower than other aeration methods. The objectives of this study were to evaluate the feasibility of using the RDC to strip VOCs from the contaminated water and to develop a mathematical model to …

Theses

Based on the anatomical structure, a structural model of the visual system was established. System responses of different stimulations were analyzed based on the model. More extensive study was made on the system impulse response. A mathematical model with parameters representing prominent process components was developed to represent the system response in a compact form and the parameters were statistically studied to correlate to the real physiological characteristics of the visual system. The parameters of the model were used to fit the system intensity response function. The result shows that it is a more quantitative way to construct the system …

The Effects Of Degraded Indoor Air Quality On Employees Working In High Rise Office Buildings, Richard Patrick Luongo

Theses

An examination of the effects of poor indoor air quality on workers in high rise office buildings was conducted. These effects are manifested physiologically, psychologically and economically and originate from sources inside and outside the building, as well as from the building's ventilation system. These sources include combustion products, microorganisms, volatile organic chemicals, cigarette smoke and miscellaneous chemicals. Lower productivity and higher absenteeism are the initial results of these effects. If the situation becomes chronic, an erosion of trust between employer and employee can occur which may eventually serve as the basis for litigation, such as worker's compensation claims and …
