Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
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 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was 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 have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.

Download or read book Continued Evaluation of Oxygen Use in Conventional Activated Sludge Processing written by Union Carbide Corporation. Linde Division and published by . This book was released on 1972 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: A process (called UNOX) for treating municipal wastewater using high-purity oxygen in the activated sludge process was further evaluated at Batavia, New York in a full scale wastewater treatment plant. The present evaluation places emphasis on the production rate, filtration, and digestion characteristics of oxygenated waste activated sludge. Operation was conducted at two different system loadings over a period of three months. The filtering characteristics of waste activated sludge from an oxygenation system were investigated. Waste activated sludge was aerobically digested in 800-gallon batches using high-purity oxygen. The economics of oxygenation systems as compared with conventional diffused air aeration systems were revised from the cost estimates presented in initial work.

Available in PDF, EPUB and Kindle. Book excerpt: "Waste activated sludge is commonly treated through anaerobic digestion (AD) in wastewater treatment plants to reduce the amount of solids waste to handle and recover energy. AD reactors are typically operated at a temperature higher than ambient to increase the kinetics of the rate-limiting step in AD process. However, since heating takes up a considerable proportion of the recovered energy, and waste disposal accounts for a substantial portion the operation budget, many pretreatment and operational methods have been developed to enhance the biosolids re-duction and potentially improve the energy recovery. One of the least investigated strategy to improve energy recovery is to reduce the operation temperature of AD once the pretreatment is applied to the waste activated sludge. This is the topic of the study in this thesis. This thesis investigated the improvement in the performance of the digestion of ozonated waste activated sludge at 15°C and room temperature (22.6±0.3°C) with the addition of zero-valent iron (ZVI) and the separation of the digester in a two-stage process. The experimental period was divided into two phases. In Phase I, a high-rate single-stage process was applied to three 4-L reactors at two different temperatures (one at 15°C and two at room temperature). ZVI pow-der was added to the 15°C and one of the two reactors at room temperature. By comparing the performance of the ZVI-free reactor (control), the effect of ZVI on pre-ozonated AD was evalu-ated. In Phase II, both reactors receiving ZVI in Phase I were transformed into two-stage diges-tion systems (i.e., fermentation reactor followed by a methanogenic reactor), while the other operation parameters (ZVI dosage, temperature, and ozone dose to the WAS) remained the same. Results obtained over 278 days of operation revealed that the addition of ZVI in Phase I increased the biogas production by 24% when operating at room temperature and increased the proportion of biomethane in the biogas from 65% to 74%. These improvements were associated with the more efficient conversion of hydrolyzed chemical oxygen demand (COD) into bio-methane because the volatile suspended solids (VSS) destruction did not significantly change. In Phase II, ZVI-dosed two-stage anaerobic digestion showed an increase in specific methane production of 5% at 15°C and 14% at room temperature compared to the same reactors in Phas-es I. These improvements were only slightly higher than the changes in the average perfor-mance of the control reactor (single-stage ZVI-free reactor at room temperature), which rec-orded an increase in specific methane production of 3%. In conclusion, ZVI addition improved the biomethane production of anaerobic digestion at low temperatures, but its effect on solids reduction was limited. Conversely, staging did not appear to provide clear additional benefits to the process. This work will contribute to the optimization of energy recovery from anaerobic digestion, and may provide new avenues to enhance the process performance for small process-es that are more sensitive to the impacts of environmental conditions"--
