Basic overview
Ultrapure water was originally produced by the U.S. scientific and technological community in order to develop ultrapure materials (semiconductor original materials, nano-fine ceramic materials, etc.) by applying distillation, deionization, reverse osmosis technology or other appropriate supercritical fine technology. Pure water has been widely used in biology, medicine, automobile and other fields. Except for water molecules (H20), this kind of water has almost no impurities, no bacteria, viruses, chlorinated dioxins and other organic matter. Of course, there are no minerals and trace elements required by the human body. Ultra-pure water has no hardness and has a better taste. Sweet, also often called soft water, can be drunk directly or boiled. Ultra-pure water is a degree that is difficult to achieve with general technology. If the resistivity of water is greater than 18MΩ*cm, it is called ultrapure water if it is close to 18.3MΩ*cm.
At present, the commonly used process methods for purifying water quality in medical ultrapure water equipment include distillation, reverse osmosis, ion exchange, filtration, adsorption, and ultraviolet oxidation. Ultrapure water equipment generally can roughly divide the water purification process into 4 major steps, pretreatment (primary purification), reverse osmosis (production of pure water), ion exchange (production of 18.2MΩ.cm ultrapure water) and terminal Treatment (production of ultra-pure water that meets special requirements). Common preparation methods: pretreatment + secondary RO + UV + EDI + polishing + microporous.
