Water Filtration System in a Straw
By Larry Greenemeier
Sometimes, it's the simplest technologies that have the greatest potential impact on people's lives. Take the Vestergaard Frandsen Group's mobile personal filtration system, otherwise known as LifeStraw. It is a powder-blue plastic tube—much thicker than an ordinary straw—containing filters that make water teeming with typhoid-, cholera- and diarrhea-causing microorganisms drinkable.
The filters, made up of a halogenated resin, kill nearly 100 percent of bacteria and nearly 99 percent of the viruses that pass through LifeStraw. A University of North Carolina at Chapel Hill evaluation tested the device's performance in water containing Escherichia coli B and Enterococcus faecalis bacteria and the MS2 coliphage virus as well as iodine and silver. The results indicated that LifeStraw filtered out all contaminants to levels where they don't pose a health risk to someone drinking the water. To view complete article:
