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 …
Promoting Renewable Energy Generation In The United States: The Debate Over Renewable Portfolio Standards, Joe Cerne
Economics Theses
Incentivizing renewable energy growth in the 21st century is, and will continue to be, a highly debated topic. As of late, legislative initiatives have prompted the enactment of various renewable portfolio standards aimed at stimulating renewable energy growth. Using data regarding each state’s energy production, this paper finds that there is no significant change in renewable energy output following the initiation of a renewable portfolio standard. We conclude that renewable energy growth is virtually unaffected by renewable portfolio standards and as such, we agree with much of the literature implying other means are necessary in order to adequately shift …
