Membrane filtration (MF) is a pressure-driven filtration process that can remove unwanted particles and contaminants from liquids and gases. The technology is used in many industrial large-scale applications as it enables industries to cost-effectively run cleaner and compliant operations free of harmful particles and contaminants.
Simply put, membrane filtration methods employ a membrane for the filtration process. A membrane is a thin layer of a semi-permeable material, which provides a physical barrier to separate molecules and particles of various sizes and characteristics. Even the smallest elements, such as bacteria and viruses, can be rejected by membranes. A membrane can be made of several organic and inorganic materials and constructed in various module designs.
This enables different types of liquids and gases to be filtered. Membrane filtration is a pressure-driven technology. No chemicals are added to treat the water and gases. Chemicals are only needed for membrane cleaning to maintain superior hygiene. Thus, it is a clean technology, securing a greener future.
