Water Purification using Carbon Nanotubes

摘要

Seldon Technologies has developed a carbon nanotube (CNT) based filtration media (Nanomesh) that takes advantage of the inherent properties of CNTs (high strength, high surface area, electrical conductivity, etc.). Because CNTs represent the ultimate limit in a fiber's diameter, the material achieves highly efficient filtration with a minimum of a pressure drop. This equates to lower power consumption to achieve the desired product (in this case, clean water). Over the past six years, Seldon has demonstrated the feasibility of using its material to clean water, air and fuels. In 2007 Seldon was issued a patent [1] for the filtration of fluids using CNTs. Additionally Seldon has demonstrated that it is possible to produce large quantities of Nanomesh on papermaking machines largely using off-the-shelf processing equipment.
