Abstract
The invention is a device for purifying drinking water that has at least one fibrous structure. Preferably, there is an upstream and downstream fibrous structure. Each fibrous structure is a mixture of nano alumina fibers and second fibers arranged in a matrix to create asymmetric pores and to which fine, ultrafine, or nanosize particles are attached. Preferably, the device has an upstream antimicrobial for sterilization of retained microbes. The device is substantially more efficient at removing soluble contaminants such as halogens from a fluid stream than those previously available and is also able to retain turbidity, bacteria, and virus.
Claims30
A filtration device, said filtration device comprising at least one cartridge, each said cartridge having a support member that supports at least one fibrous structure, each said fibrous structure comprising nano alumina fibers and second fibers mixed with said nano alumina fibers, wherein said second fibers are arranged to create asymmetric pores.
A device for purifying drinking water, said device comprising 1+y upstream fibrous structures and 1+n downstream fibrous structures, wherein y is any integer from 0 to y and wherein n is any integer flom 0 to n, each said fibrous structure comprising nano alumina fibers and second fibers mixed with said nano alumina fibers, said second fibers arranged to create asymmetric pores, said 1+y upstream fibrous structures further comprising a plurality of particles deposited on said nano alumina fibers.
