Detailed description
First, reverse osmosis pure water equipment working principle overview
Reverse osmosis technology is developed in recent years in China, a modern high-tech. Reverse osmosis is the application of a pressure greater than the osmotic pressure of the solution, so that water through a special semipermeable membrane, separated from the solution. Because this process and the infiltration of the opposite, so called reverse osmosis. According to the different osmotic pressure of various materials, you can use a solution than the osmotic pressure reverse osmosis method to achieve the separation of the solution, extraction, purification and enrichment purposes. The reverse osmosis unit is mainly separated from the ion range in the solution, which does not require heating, and no phase change process, and therefore less energy than conventional methods. Reverse osmosis device small size, simple operation, the scope of application is relatively wide. With reverse osmosis device, the treatment of industrial water, do not consume a lot of acid and alkali, no secondary pollution, its operating costs are relatively low. Reverse osmosis membrane separation technology, referred to as RO technology. I RO water purification company can make the recovery rate of 75%, desalination rate as high as 98% or more, and the key components of the US imports of reverse osmosis membrane, so that the water quality is guaranteed and the water quality and stability. System pre-processing part of the equipment are imported multi-valve control, so that the entire system is simple, high technical content, and RO water machine can also reduce the amount of acid and alkali emissions, is conducive to environmental protection. Reverse osmosis pure water equipment system according to different source water quality using different technology. General tap water by a reverse osmosis water equipment system, the water conductivity <10μS / cm, after the secondary reverse osmosis system after the water conductivity <2μS / cm or even lower, after the reverse osmosis system with ions The exchange equipment or EDI device can produce ultrapure water, making the resistivity up to 18 megohms (conductivity = 1 / resistivity).
Second, reverse osmosis water equipment works
Permeation is common in nature, such as a cucumber into the salt water, cucumber will lose water and become smaller. The process of water molecules entering the brine solution in the cucumber is the osmosis process. If a water-only membrane can be used to partition a pool into two parts, respectively, on both sides of the diaphragm were injected with pure water and brine to the same height. Over a period of time can be found pure water level decreased, and salt water level increased. The phenomenon of migrating water molecules into the brine through this membrane is called infiltration. Salt water level is not endless, to a certain height will reach a balance point. At this time the difference between the two sides of the diaphragm on behalf of the pressure is called osmotic pressure. The osmotic pressure is directly related to the concentration of brine. After the above device reaches equilibrium, if a certain pressure is applied to the liquid level of the brine, the water molecules will migrate from the brine end to the pure water end. Liquid agent molecules under pressure from the dilute solution to the concentrated solution of the process of migration This phenomenon is called reverse osmosis phenomenon. If brine is added to one end of the above facility and a pressure is applied at that end beyond the osmotic pressure of the brine, we can obtain pure water at the other end. This is the principle of reverse osmosis water equipment. Reverse osmosis facilities to produce pure water there are two key, one is a selective membrane, we call semi-permeable membrane, the second is a certain pressure. In short, the reverse osmosis semipermeable membrane has a large number of holes, the size of these holes and the size of water molecules, due to bacteria, viruses, most of the organic pollutants and hydrated ions are much larger than water molecules, The reverse osmosis semipermeable membrane is separated from the aqueous phase through the reverse osmosis membrane. In the water a variety of impurities, the dissolved salts are the most difficult to remove.Therefore, often based on the level of desalination to determine the reverse osmosis water purification effect of reverse osmosis desalination rate depends mainly on the reverse osmosis semipermeable membrane The selectivity. At present, the higher selectivity of the reverse osmosis membrane element desalination rate can be as high as 99.7%.
