Overcoming Technological Challenges For The Commercialization Of The Circulating Fluidized Bed Bioreactor For Municipal Wastewater Treatment, Michael J. Nelson
Overcoming Technological Challenges For The Commercialization Of The Circulating Fluidized Bed Bioreactor For Municipal Wastewater Treatment, Michael J. Nelson
Electronic Thesis and Dissertation Repository
The fluidized bed bioreactor as an attached growth wastewater treatment process has demonstrated advantages over suspended growth processes for municipal wastewater treatment applications. However, previous studies have also demonstrated potentially serious disadvantages in terms of energy consumption and maximum reactor size of high flow applications.
In this work, a cost analysis using the CapdetWorks, supplemented by calibrated model data taken from GPS-X was performed to determine the cost effectiveness of the circulating fluidized bed bioreactor (CFBBR). This study demonstrated that the CFBBR is most cost competitive at low flow below 5 MGD. A 10%-20% reduction in net present values on …
Co2 Derived Carbon Capture Using Microalgae In A Photobiocrec Unit, Maureen D. Cordoba Perez
Co2 Derived Carbon Capture Using Microalgae In A Photobiocrec Unit, Maureen D. Cordoba Perez
Electronic Thesis and Dissertation Repository
Microalgae has the potential to contribute to carbon dioxide capture, resulting in the production of alternative fuels and valuable chemical products. To accomplish this, high-efficiency photobioreactors must be conceptualized, designed, and established, in order to achieve high inorganic carbon conversion, superior light utilization, and unique fluid dynamics.
In this PhD Dissertation, experiments with Chlorella vulgaris were carried out, in a 0.175L especially designed PhotoBioCREC unit, under controlled radiation and high mixing conditions. This unique design involves 1 mm-2 mm alumina particles, which keep photoreactor walls always clean, without compromising photon transmittance. Sodium bicarbonate (NaHCO3) was supplied as the …
Growth Viability Assay Assessment For Disinfectant Screening, Paavana Jayaram
Growth Viability Assay Assessment For Disinfectant Screening, Paavana Jayaram
Electronic Thesis and Dissertation Repository
Disinfectant screening is an important step for manufacturing and approval of disinfectants. Screening helps identify the effectiveness, target microbe, minimum inhibitory concentration, and contact time. A standard screening test must be able to assess these parameters effectively over a broad range of formulations and microbes. Currently, there is no unified method to analyze disinfectants, a standard test is selected based on the application. This project aimed to identify a standard method that can be used over a broad range of microbes irrespective of disinfectant composition. Microbicidal activity of Hydrogen peroxide and Quaternary ammonium-based disinfectants was evaluated by Fluorescein diacetate (FDA), …
Development Of A Recombinant Brewing Yeast To Produce Beer From Hemp Extract (Cannabis Sativa L.), Mehmet Ugur Gulmen
Development Of A Recombinant Brewing Yeast To Produce Beer From Hemp Extract (Cannabis Sativa L.), Mehmet Ugur Gulmen
Electronic Thesis and Dissertation Repository
The Cannabis industry is a rapidly-growing market in Canada. With the legalization of edible products in 2019, many cannabis-derived candies, baked goods, beverages appeared on shelves. Cannabis beer can be brewed by replacing barley with pretreated cannabis plant. However, using a traditional brewing yeast to brew cannabis beer will result in incomplete fermentation which will affect the beer’s composition and flavour because traditional brewing yeasts are not able to utilize xylose which is an abundant carbohydrate in lignocellulosic extracts. Using a recombinant strain of a brewing yeast and a xylose-fermenting yeast can overcome this issue. The work presented in this …
