Reverse osmosis filter is also known as high in the 1960s developed a membrane separation technology. Because it has no phase change materials, low energy consumption, simple equipment, room temperature operation and strong adaptability and so, after forty years of development, has been widely used in various fields of national economy. From the film, components and devices to research and development, has become a mature technology of reverse osmosis membrane separation technology, it is not only used in seawater and brackish water desalination, and in electronics, petrochemical, food, health, and environmental engineering defense and other areas play an important role. Reverse osmosis is a pressure differential driven membrane separation technology, is currently the most advanced membrane separation technology. Reverse osmosis membrane is a driving force in the pressure difference effects wastewater reuse reverse osmosis desalination apparatus, allowing only water molecules through a semipermeable membrane barrier various solute and solid particles. The main factors that affect the rate of reverse osmosis desalination equipment and working: 1. ion valence: rejection rate increases while improving ion valence, bivalent, trivalent salt rejection rate is higher than monovalent salts; 2. Molecular Size : desalination rate with increasing molecular diameter and improved; 3. Raw water temperature: When the raw water temperature rises, due to lower viscosity of water desalination rate; 4. raw water concentration: when the raw water concentration is increased, the rate of decline in desalination; 5. Working pressure: When working pressure increased rejection rate has increased but not significantly; 6. PH value: under acidic conditions, although the film is not easy to plug the lowest reverse osmosis desalination plant, but the rejection rate should decline; 7. hydrogen trends: For contain compounds, strong hydrogen removal rate is very low reverse osmosis desalination unit prices, such as water, phenol and ammonia; (also, therefore able to achieve the removal of impurities in the water and solutes and achieve the purpose of separation of water and other substances: 8. Organic materials: organic matter in water pollution effects on membrane reverse osmosis desalination plant, the performance of organic matter, the more volatile the film 9. Water hardness: the higher the hardness of the water film more prone to clogging, for high hardness water should be softened, reducing Hardness and then into reverse osmosis; 10. solids: solids great harm to the reverse osmosis membrane, must be pretreated Beijing reverse osmosis desalination plant, rich students, sewage treatment by reverse osmosis desalination plant in Guangzhou Environmental Protection Engineering Co., rich students.
