Improving Flow Distribution In Small-Scale Water-Supply Systems Through The Use Of Flow-Reducing Discs And Methods For Analyzing The Effectiveness Of Solar Powered Pumping For A Drinking Water Supply In Rural Panama, Briana I. Drake

Dissertations, Master's Theses and Master's Reports - Open

As continued global funding and coordination are allocated toward the improvement of access to safe sources of drinking water, alternative solutions may be necessary to expand implementation to remote communities.

This report evaluates two technologies used in a small water distribution system in a mountainous region of Panama; solar powered pumping and flow-reducing discs. The two parts of the system function independently, but were both chosen for their ability to mitigate unique issues in the community. The design program NeatWork and flow-reducing discs were evaluated because they are tools taught to Peace Corps Volunteers in Panama.

Even when ample water …

A Technical And Cultural Feasibility Assessment Of Household Microbial Fuel Cells For Use In Hanan'g District, Tanzania, Erinn Kunik

Dissertations, Master's Theses and Master's Reports

Microbial fuel cells (MFCs) are an emerging electricity generation technology that has the potential for use in developing countries. This study assessed the feasibility of using MFCs in Tanzania through technical analysis of a MFC prototype alongside with interviews with Tanzanians for a cultural feasibility assessment of MFCs. For the technical analysis, this study evaluated the inputs needed for a household MFC to operate and produce electricity with cattle manure as a fuel and evaluated the electrochemical and chemical performance as well as the fecal coliform reduction of the manure during MFC operation. For this study, a MFC was built …
