Via Separations offers a more modular and resource efficient separation solution enabled by novel membrane materials. By pioneering a new filtration membrane based on graphene oxide for fine liquid filtration in challenging environments, the material platform improves selectivity between key nanofiltration solutes and can operate with dramatically increased temperature stability, solvent resistance, and oxidizer tolerance. Physical separations have the potential to reduce the 15% of total US energy consumption used for evaporation and distillation-based separations by a factor of 10. Spun out of the Grossman Group at MIT, Via Separations is poised to be among the first to produce commercial graphene oxide-based products that will extend the boundaries of liquid filtration.
