Altair cleans up drinking water
Altair Nanotechnologies has teamed up with the University of Nevada, Reno, US, to create nanomaterials for purifying drinking water. The technology will help to remove heavy metals, such as arsenic and selenium.
“The arsenic content in drinking water is a significant problem worldwide and in most of the western United States,” said Richard Bjur, director of the University of Nevada’s Office of Technology Liaison.
Altair will employ its technique for making titanium dioxide nanoparticles into porous crystalline catalyst support structures. The company can also incorporate additives onto the surface of these structures using chemical modifiers. The university, meanwhile, will provide its patents covering the removal of arsenic from drinking water using lanthanum compounds.
Altair expects that combining the two technologies will provide a large surface area of reactive material on a stable substrate that allows high rates of water flow and water purification.
Altair is also developing nanomaterials with applications in fuel cells, solar cells, energy-storage devices, thermal spray coatings, catalysts, cosmetics, paints and environmental remediation.
