Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Master's Theses
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 …
Application Of A High-Performance Optically Enhanced Solar Thermal Collector System, Timothy H. Cameron
Application Of A High-Performance Optically Enhanced Solar Thermal Collector System, Timothy H. Cameron
Honors Theses
In an effort to make Union College a more environmentally friendly campus, this research project focuses on the application of Union’s liquid-based solar thermal collector system. The motivation for this research project is due to the increasing demand for renewable energy sources in order to decrease our society’s dependence on fossil fuels. The system features nine, 16-tube, evacuated tube solar modules which absorb radiant solar energy from the sun. Through a two loop system, thermal energy is stored in water within two-80 gallon storage tanks. This research project involves the design, construction, and analysis of two applications in order to …
