Do you know the working principle of reverse osmosis RO membrane? Author: Reverse osmosis, also known as reverse osmosis (RO). It uses a certain pressure to separate the solvent in the solution through a reverse osmosis membrane (or semi-permeable membrane). Because it is opposite to the direction of natural penetration, it is called reverse osmosis. According to the different osmotic pressures of various materials, the reverse osmosis method greater than the osmotic pressure can achieve the purpose of separation, extraction, purification and concentration. The principle of reverse osmosis RO membrane reverse osmosis is a high-tech membrane separation technology, its pore size is very small, mostly ≤10×10-10 (10A), it can remove the ion range and molecular weight organic matter in the filtrate, such Bacteria, viruses, heat sources, etc. It has been widely used in the production of seawater or brackish water desalination, electronics, medical pure water, drinking distilled water, space water, and also used in biological and medical engineering. The characteristic is that it can separate or concentrate the solute and water under normal temperature conditions, so the energy consumption is low; the impurity removal range is wide, and the inorganic salt and various organic impurities can be removed; the high water reuse rate; the separation device is simple and easy Operation and maintenance. Application scope of reverse osmosis RO membrane: preparation of space water, purified water, distilled water, etc.; wine manufacturing and degrading water; pre-preparation of water for pharmaceuticals, electronics and other industries; concentration, separation, purification and preparation of water distribution in chemical processes; boiler make-up water Desalination and soft water; desalination of sea water and brackish water; water and wastewater treatment in papermaking, electroplating, printing and dyeing industries. Reverse osmosis is a high-tech membrane separation technology developed in the 1960s. It has a small pore size and can remove organic matter with a small ion range and molecular weight in the filtrate, such as bacteria and viruses.
