GRAPHILTER

GRAPHILTER recognizes OSN membrane could provide an efficient and environmentally sustainable alternative to current nanofiltration methods based on organic solvents. Solvent recovery and separation of oil compounds utilizing thermal evaporation processes consume tremendous energy. Organic solvent nanofiltration (OSN) is an energy-efficient separation technique that can be potentially used for solvent recovery and separation of oil compounds in the vegetable oil industry. The Company's GO-based organic solvent nanofiltration (OSN) membrane is a solvent-resistant nanofiltration membrane that gives a profound performance in long-term continuous operations. The excellent resistance of the composite layer (a hybrid of GO/polymer composite) has solved the damaging issue of OSNs in long-term operations. The OSN membrane also reduces the separation temperature from boiling point to room temperature.
