Working principle of reverse osmosis pure water equipment

Reverse osmosis pure water equipment uses a high-pressure pump to pressurize raw water, forcing water molecules to pass through a semi-permeable membrane (reverse osmosis membrane), while dissolved salts, organic matter, bacteria, and other impurities are retained, thus purifying the water. The core process includes:

Pretreatment: Removing large particles and residual chlorine through multi-media filtration and activated carbon adsorption;

Reverse osmosis: Under pressure of 5-8 MPa, water molecules pass through a 0.2-micron-thick polyamide membrane, while impurities are intercepted;

Post-treatment: Further purification through ultraviolet sterilization or ion exchange.
