Description

technical field

[0001] The invention relates to reverse osmosis membrane water treatment technology, which is a scale inhibitor for reverse osmosis membrane. technical background

[0002] Reverse osmosis technology is a membrane separation technology that uses pressure difference as power. It can remove all impurities in water - various ions, molecules, organic matter, colloids, bacteria, viruses, heat sources, etc. New technology for polluted water treatment. In recent years, membrane technology has been increasingly widely used in desalination, ultrapure water preparation, sewage treatment and various separation and purification processes in the electronics, chemical, pharmaceutical, food and other industries.

[0003] At present, the development of reverse osmosis membrane is increasing rapidly, and its application is becoming more and more extensive. Reverse osmosis systems are used in all walks of life and even in people's daily life. In the future, domestic water wi...
