The four types of pure water commonly used in laboratories are water deionized water, reverse osmosis water, and ultrapure water. These four different types of pure water have different water treatment processes and use different water. Let’s take a look at the common laboratory Several kinds of pure water equipment.
Purified water equipment is divided into the following four types according to the rate of laboratory water production:
Deionized water machine is a kind of deionized water equipment, which is a water treatment device that removes anion water in water through reverse osmosis, electrodialysis, ion exchanger, EDI and other methods.
The laboratory water purifier adopts a two-stage reverse osmosis water treatment process, an enhanced pre-three-stage pretreatment system, which effectively removes impurities and particulate matter, and produces RO pure water and UP ultra-pure water. One machine with dual purposes, can produce pure water with a resistivity of up to 18.2 megohms. The pure water produced by the pure water instrument is mainly used for experimental water and analytical instrument water. The most commonly used equipment for producing pure water in laboratories is ultra-pure water equipment. The pure water equipment is equipped with a raw water pretreatment system and an ultra-purified post-treatment system (mixed bed ion exchange water treatment technology, EDI water treatment technology, and ultra-pure water treatment technology). Filter membrane, pyrogen-removing ultrafiltration membrane, ultraviolet germicidal lamp and TOC ultraviolet digester, terminal filter), reverse osmosis purification system. To Among them, the reverse osmosis membrane can remove organic matter, microorganisms, and more than 98% of the remaining trace ions, organic matter and other impurities in the raw water quality at one time. The ultra-purification post-treatment system is connected to the reverse osmosis membrane system, and the main purpose is to gather a variety of water treatment technologies to remove the remaining trace ions, organic matter and other impurities in the water to meet the final water quality index requirements for different purposes.
