(' , ' h', , reverse osmosis, the English name, is a new membrane separation technology developed in the 1960s. It is a membrane separation and filtration technology that uses pressure difference as power. It originated from the American aerospace industry in the 1960s. The research on science and technology was gradually transformed into civilian use, and it has been widely used in scientific research, medicine, food, beverages, seawater desalination and other fields. In industrial ultrapure water, such as electronics, electric power ultrapure water, chemical industry, electroplating ultrapure water , the preparation of boiler feed water and ultrapure water for medicine is often used as the first stage treatment of deionization and electrodeionization (D). Compared with the traditional use of ion exchange resin as the preliminary pretreatment process, reverse osmosis has It has the advantages of more economical, more energy-saving, more stable operation and more reliable water quality, and can greatly extend the regeneration cycle of the post-stage ion exchange resin and the cleaning cycle of the electrodeionization (D).
bz ' , ' h', , >bz'' >Osmosis is a physical phenomenon. When two waters containing different concentrations of salts are separated by a semi-permeable membrane, you will find that the water on the side with less salt content will pass through the membrane. It penetrates into water with high salt content, but the salt contained does not penetrate. In this way, the salt concentration on both sides is gradually blended until it is equal. This process is called natural osmosis. Reverse osmosis is a kind of pressure-driven, with the help of A separation method that uses the selective interception of a semipermeable membrane to separate solutes and solvents in a solution.
