Identifiying cost savings through energy conservation measures in mechanically aerated activated sludge treatment processes in southeast FloridaUnknown Date (has links)
This thesis presents a model which estimates energy and cost savings that can be realized by implementing Energy Conservation Measures (ECMs) at mechanically aerated wastewater treatment plants (WWTPs) in southeast Florida. Historical plant monitoring data is used to estimate savings achieved by implementing innovative aeration technologies which include : 1) Fine Bubble DIffusers ; 2) Single-Stage Turbo Blowers ; 3) Automatic Dissolved Oxygen (DO) Control. Key assumptions for modeling performance of each technology are researched and discussed, such as trends in the future cost of electricity, efficiency of blowers, and practical average DO levels for each scenario. Capital cost estimates and operation maintenance (O&M) costs are estimated to complete life-cycle cost and payback analyses. The benefits are quantified on an individual and cumulative basis, to identify which technologies are cost-beneficial. The results demonstrate that levels of payback of 20 years or less are available at the three WWTPs studied. / by Eric Stanley. / Thesis (M.S.C.S.)--Florida Atlantic University, 2012. / Includes bibliography. / Electronic reproduction.

Government Policy and Private Organizational Forms: Analysis of Refuse Collection and Disposal in Three Metropolitan CitiesWright, Thomas 01 January 1996 (has links)
This study explores refuse collection as a municipal service using qualitative methods to examine how government makes decisions about residential refuse collection services in Portland, Gresham, and Beaverton, Oregon. The study explores the history of refuse collection in these three cities to identify factors that influence bureaucratic behavior and decision making when selecting a municipal service delivery option for refuse collection. Public choice and public policy analysis theory are used to discuss those non-monetary considerations present when government makes decisions about service arrangements. Qualitative data was collected from public officials and private haulers involved in refuse collection in the three cities. This qualitative process was to capture, in context, the development of the industry. The use of a single criterion in determining choice of private organizational forms may not create the results desired by municipal governments. Choice in the selection of a service arrangement has two important aspects: (1) the array of service arrangement options that can be developed and (2) the contextual environment within which bureaucrats operate and which influences the decision making process. It was found that decisions about which type of service arrangement to use for refuse collection did not always stem from monetary factors such as cost. Non-monetary factors such as tradition, legal considerations, and lobbying can influence decisions about which type of service arrangement to use.
