Membrane filtration is a pressure-driven separation process that MS® MF membrane has helped pioneer for the industrial, food, water, chemical, and biotechnology markets, as well as for those providing environmental protection.
MS®MF membrane serve as highly-engineered, physical barriers that permit the passage of materials only up to a certain size, shape or character. MS® offers membrane products in a variety of configurations, materials and sizes; each designed to meet specific application needs.
There are multiple membrane materials currently employed for liquid/liquid, liquid/solid and gas/solid separation: PES membrane, PTFE membrane, PVDF membrane, NY membrane and PP membrane.
