Technical principle and process analysis of two stage reverse osmosis equipment
1. This product is the latest two-stage reverse osmosis purification water equipment manufactured by Wenzhou Haidoneng Environmental Protection Technology Co., Ltd. The production time is 20 tons. The reverse osmosis equipment system adopts different processes according to different water quality of the source water.In general, after the water is treated by the first-stage reverse osmosis equipment system, the water production conductivity is less than 10 μs /cm, and after the second-stage reverse osmosis equipment system, the water production conductivity is less than 2 μs /cm or even lower. After the reverse osmosis equipment system, the ion exchange equipment or EDI equipment can be used to prepare ultra-pure water, and the resistivity can reach 18 megohm (conductivity =1/ resistivity).
2. Reverse osmosis equipment is a reverse osmosis membrane that forces water molecules to pass through water molecules selectively with the help of pressure, that is, the principle of reverse osmosis water purification. This device is for the reverse osmosis device root according to the different osmosis pressure of various materials, which can be separated, extracted, purified and concentrated by reverse osmosis method greater than osmosis pressure.Can remove more than 98% of the dissolved salts and more than 99% of the colloid, microorganisms, particles and organic matter, become the modern pure water, space water (ultra pure water) engineering equipment.
3. Reverse osmosis technology is a modern high-tech technology developed in China in recent years.Reverse osmosis is to apply a pressure greater than osmotic pressure to the solution, so that the water through a special semi-permeable membrane, separated from the solution.Because this process is the opposite of osmosis, it is called reverse osmosis.According to the different osmotic pressure of various materials, the reverse osmosis method larger than osmotic pressure can be used for some solution to achieve the purpose of separation, extraction, purification and concentration of the solution.Reverse osmosis device, mainly to separate the range of ions in the solution, it does not need heating, there is no phase change process, so the energy consumption is lower than the traditional method.Reverse osmosis equipment is small in size, simple in operation and wide in application.With reverse osmosis equipment, industrial water treatment, does not consume a lot of acid and alkali, no secondary pollution, its operation cost is relatively low.Reverse osmosis membrane separation technology, referred to as RO technology.
