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 …

Design And Implementation Of Iso:9001 Standards At Sigma 6 Electronics, Inc., Robert Kirkpatrick, Dylan Geisen, Simon Schermerhorn
Industrial Technology and Packaging
ISO 9001 certification is a very long process that can take even the most dedicated team years to complete. For smaller companies such a process could be costly, confusing, and arduous. While many resources exist, it takes nearly the same amount of effort to tailor fit the examples as it does to create a whole new set.
The purpose of this senior project is to research examples and help fit them to a small manufacturing company, Sigma 6 Electronics, Inc. An interlinked, or combined, quality manual/procedures were chosen to aid Sigma 6 Electronics through making the documentation clear and perfectly …
