What Is A Reverse Osmosis Membrane?

Reverse osmosis membranes are a critical part of commercial and industrial water treatment systems. A reverse osmosis (RO) membrane filters out dissolved salts, contaminants, and impurities by allowing only water molecules to pass through. It plays a critical role in the RO system, directly determining the quality of the purified water. As membranes age, they clog or degrade, which reduces water output and purity. Replacing old membranes restores system efficiency, maintains water quality, and prevents strain on other components. Regular replacement keeps the system running smoothly and avoids costly repairs.
