Reverse Osmosis (RO) is a membrane separation technology that uses pressure difference as the driving force. When the applied pressure exceeds the osmotic pressure of the feed water, water molecules pass through the semi-permeable membrane into the permeate channel, while dissolved impurities (such as ions, organic matter, bacteria, and viruses) are retained on the other side and discharged through the concentrate outlet.

This process achieves efficient purification and separation of water. RO technology is internationally recognized as one of the most efficient and reliable methods for producing purified water. It is widely used in industrial production, drinking water purification, laboratory water preparation, food and beverage, and pharmaceutical industries to remove dissolved solids, microorganisms, and other contaminants from water.
