Book Masters Theses in the Pure and Applied Sciences

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book Simultaneous Modeling of Competitive Adsorption and Dual Substrate Biodegradation in Completely Mixed GAC Reactors

Download or read book Simultaneous Modeling of Competitive Adsorption and Dual Substrate Biodegradation in Completely Mixed GAC Reactors written by Ulrich Karl Traegner and published by . This book was released on 1990 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fluidized-bed anaerobic GAC reactor, operating with GAC replacement, has been demonstrated to promote effective treatment of high strength industrial wastewaters which contain refractory and toxic chemicals that resist biodegradation and inhibit the fermentation of the biodegradable constituents of a wastewater. The objective of this study was, to develop a mathematical model, capable of predicting the steady-state and transient performance of three fluidized-bed anaerobic GAC reactors treating synthetic wastewaters consisting of the readily biodegradable acetate, the biodegradable, adsorbable, but self-inhibitory phenol, and the non-biodegradable, inhibitory but adsorbable o-cresol. These reactors were operated with different GAC mean solids residence times, varying from 8 days to 60 days. Special features of the activated carbon mixed-culture biofilm model include: diffusional mass transport across a concentration boundary layer and within the biofilm, and the distinction between two microbial species, namely the phenol and the acetate utilizing microorganisms, which compete for attachment surface and spatial occupation within the limited space of the biofilm. Transport of phenol and o-cresol within the GAC particle was modeled using competitive adsorption and the homogeneous surface diffusion model. The model furthermore incorporated the effects of inhibition of phenol degradation by o-cresol, and biomass loss by shearing. Equilibrium and kinetic parameters in this model were obtained from independent isotherm and closed batch adsorption experiments. Biokinetic constants were determined from closed batch experiments using fermenter effluent as a source for microorganisms. The model predictions were in good agreement with the experimental data for the full range of operational conditions of the anaerobic reactors. In this study it was found that the overall first-order shear loss coefficient can not be assumed constant, but varies with the degree of biomass coverage of the carbon particles. This finding was supported by experimental results of biological activity measurements on the active biomass. Since no a priori distribution was assigned for the two microbial species present in the biofilm, the composition within the biofilm changed for each steady-state of operation. The non-uniform species distribution of the microorganisms resulted in preferential shearing of one microbial group over another. This differential shear was verified experimentally.
