High Flux Ultrafiltration and Nanofiltration Nanofibrious Membranes Containing Cellulose Coating by Ionic Liquids

An improved, cost-effective, and non-toxic separation membrane for oil/water emulsions and several fluid separation systems Background: Conventional composite membranes currently run into the issue of pore blockage when soaked in amine solutions. The clogged pores create increased coating thickness, which decreases the flux rate. Cellulose is being...

High-flux thin-film nanocomposite reverse osmosis membrane for desalination

Use of nanofiber composites to create a higher filtration rate in reverse osmosis for energy efficient separation Background: Reverse osmosis (RO) is one of the most energy efficient separation technologies to remove salt ions from brackish water or seawater. Conventional RO membranes possess a thin film composite (TFC) structure, containing an ultra-thin...

High Flux and Low Pressure Drop Nanofibrous Microfiltration Membranes for Removal of Bacteria and Viruses

A novel application of composite nanofibers for the creation of high performance water filters. Background: Waters contaminated with bacteria, viruses, and toxic heavy metal ions are responsible for up to 1.8 million deaths each year. Although methods such as ultra-filtration and reverse osmosis have been discovered to remove viruses, these methods...
