Reverse osmosis (RO) membranes play a critical role in water filtration by removing impurities, contaminants, and dissolved solids from water. These semi-permeable membranes feature tiny pores that allow water molecules to pass while blocking larger particles, such as salts, chemicals, and microorganisms. Operating under pressure, the water is forced through the membrane, separating impurities into a concentrated waste stream. This results in clean, purified water on one side and brine on the other. RO membranes are essential for residential, commercial, and industrial applications, offering effective solutions for safe drinking water and specific processes requiring high-purity water. Their efficiency ensures reliable filtration.
