Brittney Dawney

I am currently employed as an environmental engineer for a consulting firm in Ontario, Canada, where I work on environmental projects for the railway and automotive industries, as well as emergency spill response. I am a graduate of the Civil Engineering program at Queen's University. After completing the general portion of the curriculum and gaining basic knowledge in the areas of environmental engineering, hydraulics, structural design, and geotechnical engineering, I decided to focus my studies on environmental engineering and appropriate technology. As an undergraduate, I was a member of the Queen's Applied Sustainability Group (QAS) - Appropedia page here.

Interested in water, sanitation, and hygiene for international development, with a focus on applications of appropriate technology in impoverished regions.

Research: Optimizing the SODIS Method by Decreasing Turbidity with NaCl[edit | edit source]

Research that I completed as a member of QAS has been published in the Journal of Water, Sanitation, and Hygiene for Development. The research investigates the use of common table salt (NaCl) as a flocculating agent to remove suspended clay particles in solution as a pre-treatment to Solar Water Disinfection (SODIS). The project page is available Decreasing turbidity to optimize solar water disinfection on Appropedia. The full Open Access version of the article is available here.

Past Projects[edit | edit source]

Household Water Treatment[edit | edit source]

This research was aimed at decreasing turbidity in water prior to solar water disinfection (SODIS) using basic table salt (NaCl) to facilitate flocculation of particles and subsequent settling. My project page can be viewed here.

Appropriate Technology[edit | edit source]

I worked on a project for MECH 425, where my focus was on the development of a low-cost household water treatment unit based on solar water disinfection (SODIS) technology. The aim of the project was to optimize the traditional SODIS design by decreasing turbidity prior to solar treatment. It should be able to be reproduced with minimal materials and technical knowledge in almost any place of need. The MECH 425 AT Project page can be found here.

Green IT[edit | edit source]

I worked on a Green IT project for MECH 425: Engineering for Sustainable Development. The goal of the project was to encourage organizations to employ energy conservation measures that will both reduce their operational costs and minimize their environmental footprint.
My group created an original model that can be used by organizations that are looking to capitalize on energy conservation measures. This particular model will allow organizations to explore the financial and environmental savings that are possible by shifting from using conventional ground and air mail services to electronic document sharing systems. A full description of my group's project and the model can be found here.

Waste Management[edit | edit source]

As an individual project for CIVL 472: Waste Management, I conducted a critical review of the current state of waste management methods employed by municipalities that experience very heavy tourist traffic. The city of Paris was used as a case study and its current means of waste management and diversion techniques were explored and compared to more effective contemporary methods in other cities. Recommendations were offered for application of these techniques to Paris and other highly-concentrated tourist regions in the world.

The Appropriate Technology Sourcebook reviews over 1,150 of the best books on appropriate technology. Most of the literature in the sourcebook is under copyright although some is in the public domain; those in the public domain are in the process of being made available by students in MECH 425: Engineering for Sustainable Development.

Green AT Project[edit source]

Hi Brittney

This is Simon (MECH 425), I just have a question regarding to the Green AT project topic that u chose - Water Purification system. I have an idea of natural convected solar water purification system. Basically it heats up the air using piles of aluminum can(painted in black) under the sun and the heated air is then directed(natural convection) to power a water vaporizer (heat exchanger). I just wondering if there is any overlapping with your project.

Solar PV end of life[edit source]

Hi Brittney

All very good points and questions -- there is considerable work that has gone into recycling efforts for PV -- and actually my group is just finishing a paper that focuses on setting up policy to encourage manufacturers to collect, disassemble and recycle their modules. Most of the materials in PV modules can be re-used. See this [1] for what we have been up to -- Joshua 22:45, 2 February 2010 (UTC)

AT Sourcebook[edit source]

Hey group.. heads up here...

The housing and construction section on the AT Sourcebook page has approximately 80 entries. Our CD only had 47... so we are missing about 30 and don't even have files. Something to talk about tonight at 9:30.
