Hebei Industrial Reverse Osmosis Equipment Supplier Explains: The Working Principle of Industrial Reverse Osmosis Equipment

　　 Hebei Industrial Reverse Osmosis Equipment Suppliers Before the explanation, let's first understand what osmosis is. Osmosis is a common phenomenon in nature. For example, if a cucumber is placed in salt water, the cucumber will lose water and shrink. The process of water molecules in the cucumber entering the salt solution is the osmosis process. If a pool is divided into two parts using a membrane that only water molecules can penetrate, inject pure water and salt water to the same height on both sides of the membrane. After a period of time, it can be found that the amount of pure water has decreased, while the amount of salt water has increased. We call the phenomenon of water molecules migrating through the membrane into the salt water osmosis. The rise of the salt water level is not endless; it will reach an equilibrium point at a certain height. At this time, the pressure represented by the liquid level difference between the two ends of the membrane is called osmotic pressure. The magnitude of osmotic pressure is directly related to the concentration of salt water.

　　Through the above Hebei Industrial Reverse Osmosis Equipment Suppliers introduction, let's look at what reverse osmosis is. After the above device reaches equilibrium, if a certain pressure is applied to the surface of the liquid on the salt water side, the water molecules will migrate from the salt water side to the pure water side. The phenomenon of liquid molecules migrating from a dilute solution to a concentrated solution under pressure is called reverse osmosis. If we add salt water to one end of the above facility and apply pressure exceeding the osmotic pressure of the salt water to the other end, pure water can be obtained at the other end. This is Hebei Industrial Reverse Osmosis Equipment Suppliers the principle of industrial reverse osmosis equipment. There are two key factors in producing pure water in industrial reverse osmosis equipment. One is a selective membrane, which we call a semipermeable membrane, and the other is a certain pressure.

　　In short, Hebei Industrial Reverse Osmosis Equipment Suppliers what we are talking about is that there are many pores on the reverse osmosis semipermeable membrane. The size of these pores is equal to the size of water molecules. Since bacteria, viruses, most organic pollutants, and hydrated ions are much larger than water molecules, they cannot penetrate. It passes through the reverse osmosis semipermeable membrane and separates from the water passing through the reverse osmosis membrane. Among the various impurities in water, soluble salts are difficult to remove. Therefore, the water purification effect of reverse osmosis often depends on the high or low desalination rate. The high or low desalination rate of reverse osmosis mainly depends on the selectivity of the reverse osmosis semipermeable membrane. At present, the desalination rate of high-selectivity reverse osmosis membrane elements can be as high as 99.7%.
