`Super` sand could improve water filtration
Ordinary sand, such as that from beaches, could be used to filter dirty water using a nanotech-based technique developed by researchers. Sand, which retains bugs and chemicals in water flowing through it, has been used as a cheap water filtration method for hundreds of years. Coarse sand filters water faster than finer sand, but produces water that is less clean. Now, a team of scientists in ...
