Preparation of hand-held gravity-driven water filters with high throughput and water disinfection performance |
| abstract |
A hand-held gravity-driven water filter with high throughput and water disinfection performance is formed. The membranes used in the water filters can be made using electrospinning and non-solvent induced phase inversion. A novel composite membrane structure (interwoven composite structure) was designed to further enhance water permeability and mechanical strength. Composite membranes may be composed of nanofibers of different diameters from the same polymer or different polymers. The porosity and surface pore size of the membrane can be controlled. Silver nanoparticles can be loaded in situ on the surface of the membrane. The developed filters are effective in removing a wide range of contaminants (e.g., pathogens, suspended solids, and heavy metals). The purification process can be performed under gravity drive (with options for mechanically enhanced filtration) without the need for electricity. |
