The professional term for pure water equipment is reverse osmosis equipment, which utilizes the principle of osmosis to produce purified water or pure water. Reverse osmosis is a membrane separation technology that forces the solvent (water) from the feed solution to permeate through the membrane to the other side. Substances such as ions, organic matter, bacteria, and viruses are retained on the feed side of the membrane and then discharged with the concentrated stream, thereby achieving the separation of water from other substances in the water. Reverse osmosis (RO) equipment produces water of very high purity. In industrial production, it is often used for raw water desalination to produce pure water, purified water, etc. The reverse osmosis process is commonly used to produce pure water, purified water, and ultrapure water, involving industries such as chemicals, coal power, circulating cooling, electronics, electroplating, metallurgy, boiler feed water, domestic drinking water, biotechnology, nuclear power, food processing, and more.
