Introduction to SWRO Membrane
Seawater reverse osmosis (SWRO) membrane is a crucial component in the seawater desalination process. It works based on the principle of reverse osmosis, where pressure is applied to the seawater side to overcome the osmotic pressure, forcing water molecules to pass through the semi - permeable membrane while retaining salts, impurities, and other solutes. This technology has revolutionized the way we obtain fresh water from the vast and abundant seawater resources. SWRO membranes offer high salt rejection rates, high water flux, and long - term stability, making them an ideal choice for large - scale desalination plants and various industrial applications where high - quality water is required.
