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 …

Charge. Point, Lauren Alessandra Wilson

Architecture Senior Theses

The goal of this thesis is to reduce dependence on fossil fuels, lower the carbon emission footprint, and ignite a paradigm shift towards clean energy usage. Architecture can play a role in increasing the accessibility of sustainable modes of transit by changing the way energy is produced and distributed throughout the city. Accepting both the reliance and privatization of the automobile as givens, this idea caters to a transitional stage of travel, shifting from internal combustion engine vehicles to electric powered vehicles. Current technological limitations are stunting the momentum of a sustainable transit phenomenon, i.e. EV battery charge time and …
