The Reverse Osmosis System (RO) stands as a core solution in modern water treatment technology. Leveraging its high-efficiency separation capability and broad application scenarios, it has become one of the key technologies addressing global water scarcity and pollution challenges.
Working Principle of the Reverse Osmosis System
The essence of the Reverse Osmosis System lies in the selective permeability of semipermeable membranes. Its operational principle is based on reversing natural osmosis: By applying external pressure (typically 6–20 bar), water molecules are forced to pass through an RO membrane with a pore size of 0.0001 microns (0.1 nm) from a high-concentration solution (e.g., saline water), while dissolved salts, organic compounds, microorganisms, and other impurities are retained. This achieves water purification without heating or chemical additives, making it a physical separation technology characterized by low energy consumption and no secondary pollution.
Key Components of a Reverse Osmosis System
1. Pretreatment Unit: Includes multi-media filters, activated carbon adsorption, and softening units to remove suspended solids, residual chlorine, and reduce water hardness, safeguarding RO membranes from fouling.
2. High-Pressure Pump: Provides the pressure required to drive water molecules through the membrane, serving as the primary energy consumption source in the system.
3. RO Membrane Modules: Constructed from materials like polyamide composite membranes (PA), these modules reject over 98% of dissolved contaminants, including heavy metals, viruses, and colloids.
4. Post-Treatment Unit: Enhances product water purity through methods like UV sterilization or ion exchange units to meet specific industrial requirements.
