Nanofilter's electropotential eliminates contaminants

摘要

The fiber feels like soft paper, but it's made of nanosized strings of minerals. When water flows through this material, its nanosized, aluminum-oxide-based strands grab and hold microscopic pathogens and other tiny particles.rnThe science behind it seems simple: the flowing water sets up a positive charge on the nanofibers, which can adsorb passing particles. Those particles include pathogens such as E. coli and Salmonella according to tests conducted by the fiber's maker, Ahlstrom Filtration LLC, and other companies that use the material in their products.
