Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson Dec 2014

Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson

Master's Theses and Project Reports

Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.

In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced ...


Climate Planning In Politically Conservative Cities: A Case Study Of Seven Climate Action Plans, Coleman Moore Frick Jun 2014

Climate Planning In Politically Conservative Cities: A Case Study Of Seven Climate Action Plans, Coleman Moore Frick

Master's Theses and Project Reports

Current research indicates that the potential risks associated with human-induced climate change are likely to increase in frequency and intensity. Although there have been several attempts, no effective international treaty or policy has been enacted by the United States with the purpose of combating this global issue. In the past decade, local climate action plans (CAPs) have emerged as a planning solution designed to reduce greenhouse emissions (GHGs). Previous studies have examined CAP attributes, but no research has focused solely on climate planning in politically conservative jurisdictions. This research finds that of 245 CAPs completed to date nationally, approximately 90 ...


City Of San Luis Obispo Open Space Vegetation Management Plan, Danielle Rose Althaus Jun 2014

City Of San Luis Obispo Open Space Vegetation Management Plan, Danielle Rose Althaus

Master's Theses and Project Reports

This Master’s Professional Project is focused on the development of a draft Vegetation Management Plan for the City of San Luis Obispo Open Space properties. The purpose of the plan is to provide a comprehensive document which identifies how the city is addressing wildfire preparedness in city-owned open space properties. Methods used in plan development include a literature review, content analysis, geographic information systems (GIS), a course audit, and consultation with city staff and other stakeholders. Each open space property is identified in the plan, describing its location, vegetation, topography, assets, access points, water supply, evacuation routes, historical fire ...
