Nanotechnology – the Future of Drinking Water?
Regions of the world suffering from extensive droughts and water shortages might find a long-term solution with nanotechnology, researchers are saying.The reality of this type of water filtration system could be closer than some think, because other technologies are too expensive and difficult to maintain for the poor conditions in which the inhabitants live. Carbon nanotubes, being simple in design but very effective in operation, might be the answer. The structure of these tubes allows only very small molecules – such as water molecules – to pass through. The thickness of these carbon fibers is less than a billionth of that of a strand of human hair, which still keeps out harmful agents such as bacteria, viruses and metals.
In addition to the efficient engineering behind these nanotubes, the power needed to drive water through a system would be comparatively low to conventional practices. It’s important to take note of this effort to bring clean water to a drought-stricken population, because over one billion people alive today are without access to safe drinking water. An estimated 2.4 billion people on top of that are said to have improper water sanitation, with the majority living in developing countries.
