MEMBRION is an NSF SBIR funded spin-out from the University of Washington that has developed a novel membrane technology that lowers the cost of filtering molecules in harsh environments. It’s made from commodity silica gel, commonly found as a desiccant in food packing, with pores as small as a few molecules wide. Low cost molecular filters also have commercial upside with the potential to capture a market that spans applications in water purification, pharmaceutical development, gas separations, batteries, fuel cells and food processing.
