Introduction to SWRO Membrane
SWRO (Seawater Reverse Osmosis) membrane is a crucial component in seawater desalination technology. It works based on the principle of reverse osmosis, which allows water molecules to pass through the semi - permeable membrane while rejecting salts, minerals, and other impurities. This process is energy - efficient compared to traditional desalination methods and has become the mainstream technology for producing fresh water from seawater. SWRO membranes are widely used in coastal cities, islands, and industrial areas with high water demand but limited fresh water resources. They are also applied in some large - scale water treatment projects to meet the strict water quality requirements for various industries.
