Foreword: Nanjing Shuaibo Machinery Equipment Factory is a high-tech enterprise specializing in the production of complete sets of fluid equipment such as two-stage reverse osmosis pure water equipment , multi-effect distilled water machine and liquid distribution system. It has been committed to the development of China's water treatment industry. With the spirit of enthusiasm, advanced technology and rich practical experience, we provide our customers with quality and stable pre-sales and after-sales services in various water treatment fields.
Reverse osmosis technology is an effective membrane separation technology for today's zui advanced and zui energy saving. The principle is that these substances and moisture are separated according to the osmotic pressure of the solution, according to the fact that other substances cannot pass through the semipermeable membrane. Since the membrane pore size of the reverse osmosis membrane is very small (only about 10 A), it is possible to effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water (removal rate is as high as 97% to 98%). Reverse osmosis is a widely used desalination technology in high-purity water equipment. It is separated from organic matter in the range of ions and molecular weight in solution; reverse osmosis (RO), ultrafiltration (UF), microporous membrane filtration ( Both MF) and Electrodialysis (EDI) technologies are membrane separation techniques.
The principle of reverse osmosis :
First of all, we must understand the concept of "infiltration". Infiltration is a physical phenomenon. When two different concentrations of water, such as a semi-permeable membrane, separate, it will be found that the water with a small amount of salt will pass through. The membrane penetrates into the water with high salt content, and the salt is not penetrated. Thus, the salt concentration on both sides is gradually merged to equal. However, it takes a long time to complete the process. This process is also called For infiltration. However, if a pressure is applied to the water side with a high salt content, the result can stop the above-mentioned permeation. If the pressure is increased, the water can be infiltrated in the opposite direction, and the salt is left. Therefore, the opposite The principle of permeation and desalination is to apply a pressure greater than the natural osmotic pressure in the salty water (such as raw water), so that the penetration proceeds in the opposite direction, and the water molecules in the raw water are pressed to the other side of the membrane to become clean. The water, in order to achieve the purpose of removing impurities and salt in the water.
