Clean water is a constant concern for third world countries and nanotechnology may provide a solution. The problem is solved by using a teabag shaped and sized filter which is used as a sieve for the water.
Developed in South Africa by Marelize Botes, the University of Stellenbosch researcher is conducting final tests on the tiny water filter in her laboratory. The microbiologist said that the filter is much cheaper than bottled water as well as any other filter on the market.
It literally brings a practical application of nanotechnology to the poorest of people. The bag contains active carbon granules and is made from nanofibers treated with biocide. This kills bacteria rather than simply filtering them away from the water.
This is a water filter which will find great use in the continent of its invention. Countries such as Somalia, Mauritania and Sudan have high need of such technology to curb water borne illnesses. It is simple to use and effective to boot.
