LifeStraw Project
Dear Friends:
My husband is organizing a mission with the "Engineers Without Borders" to transport and provide life-saving water filters to people in West Africa in the Summer 2008. The project is under construction and want you to know that you will be able to donate to this cause in the near future. The best part is that the money goes directly into purchasing filters and getting them into the hands of the people without any middlemen.
To learn more about the filters view the site below.
The LifeStraw is an instant water purification filter designed by the Danish Vestergaard Frandsen Group.[1]. The device is able to clean bacteria, such as typhoid, salmonella, Escherichia coli, and cholera, from water for people living in third world countries[2].
Construction: The LifeStraw is a plastic tube 25 centimeters long and 29 millimeters in diameter[3], and costs around $2.00[4]. Water that is sucked through the straw first passes through a mesh of 100-micrometer spaces, then through a mesh of 15-micrometer spaces. Water then passes through a chamber with iodine-coated beads, killing remaining bacteria. The water passes through an empty chamber, then finally passes through active carbon, removing the iodide taste and medium-sized bacteria.[5] The entire process is powered by regular sucking, similar to using a conventional drinking straw, and filters up to 700 liters of water.[6] The filter currently does not work against Giardia lamblia, but the company is working on that.
