nanotechnology in water tratment

Water treatment
Given the importance of clean water to people in developed and developing countries, numerous organizations are considering the potential application of nanoscience to solve technical challenges associated with the removal of water contaminants. Technology developers and others claim that these technologies offer more effective, efficient, durable, and affordable approaches to removing specific types of pollutants from water. A range of water treatment devices that incorporate nanotechnology are already on the market and others are in advanced stages of development. These nanotechnology applications include:

•Nanofiltration membranes, including desalination technologies;
•Attapulgite clay, zeolite, and polymer filters;
•Nanocatalysts;
•Magnetic nanoparticles; and
•Nanosensors for the detection of contaminants.
