What is the working principle of reverse osmosis equipment? 2012-02-10 16:24:02(Has been accessed 18146 times) System of reverse osmosis equipment, desalination rate is generally 98-99%, the desalination rate in most cases is to meet the requirements in the electronics industry, high pressure boiler feed water, the individual in the pharmaceutical industry on pure water requirements may be higher. The single-stage reverse osmosis equipment can not meet the requirements.
Penetration phenomenon is common in nature, such as a cucumber into the salt water, the cucumber will be smaller due to water loss. The water molecules in the cucumbers into the brine solution process is the penetration process. If only the water molecules through the film will be a pool partition into two parts, on both sides of the diaphragm were injected into pure water and saline to the same height. Reverse osmosis equipment over a period of time can be found in the pure water surface is reduced, the salt water surface increased, water molecules migrate through the diaphragm to the salt water of the phenomenon is called the penetration phenomenon. Saline liquid level rise is not endless, to a certain height will reach an equilibrium point. At this time the diaphragm both ends of the surface represented by the pressure is called osmotic pressure. The size of the osmotic pressure is directly related to the concentration of salt water.
The balance of the above devices, if you put some pressure on the surface of the brine side, this time, the water molecules will migrate to the pure water side by the salt water side. Liquid molecules under pressure by the process of migration in dilute solution to concentrated solution, a phenomenon known as reverse osmosis phenomenon. If salt water is by adding more facilities at one end, and to exert pressure over the brine osmotic pressure in the end, we can get pure water at the other end. This is the reverse osmosis water purification principle.
The key to reverse osmosis equipment and facilities, the production of pure water there are two, one is a selective membrane, which we call semi-permeable membrane, the second is a certain pressure. Simply put, reverse osmosis semi-permeable membrane has many holes, the size of these holes the size of the water molecules, most of the organic pollutants and hydrated ions than water molecules is much greater due to bacteria, viruses, and therefore can not through over reverse osmosis semi-permeable membrane with water through reverse osmosis membrane phase separation. Many kinds of impurities in the water soluble salts is the most difficult to clear, therefore, often according to the level of the desalination rate to determine the effect of reverse osmosis water purification reverse osmosis desalination rate depends mainly determined by reverse osmosis semi-permeable membrane selectivity, the present, the high selectivity of reverse osmosis membrane elements desalination rate can be as high as 99.7%.
