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 …

Sustainable Fire Clearance Using Goats Teaching Unit, Elida Noren Moore

Agricultural Education and Communication

This project was created in order to fulfill the need of creating a unit of teaching for sustainable fire brush clearance using goats. The beginning goes over all the literature that was used to help create the project as well as the thought process that was followed in order to write the unit. These decisions were crucial for figuring out what was going to be included in the unit as well as the activities and lecture prompts that are provided. The unit covers everything from fire history and fire regulations in the state of California, to the care and treatment …
