Ultrapure water, which is a high-purity water, is often used in industries such as aerospace, electronic information, cosmetics, medical and pharmaceutical, and semiconductors. It is called ultrapure water because of its simple composition, which contains almost nothing except hydrogen atoms and oxygen atoms. Metal ions, minerals, organic matter, trace elements, etc., which are present in ordinary water, are not present in ultrapure water, and bacteria and microorganisms are also removed. Therefore, the use of ultrapure water as a raw material for production or to clean precision products in industrial production is of great value to ensure product safety.
So, how is such high-purity water produced?
This is produced by professional EDI ultrapure water equipment. This is an ultra-pure water production equipment that adopts the "two-stage reverse osmosis + EDI" technology, and the effluent quality strictly implements the relevant requirements and the quality is reliable.
Two-stage reverse osmosis means that the water treatment in the equipment is filtered through two reverse osmosis membrane systems to fully remove various impurities contained in the water. The reverse osmosis membrane uses nano-level separation materials, with good water penetration effect and large membrane flux, and it can achieve water filtration without any chemical reaction assistance, only through simple pressurization operation. After the treatment of the two-stage reverse osmosis membrane system, the metal ions, organic matter, microorganisms and bacteria in the ultrapure water are basically removed, and the effluent quality is very good.
EDI technology enables deep desalination of ultrapure water. It can enable charged operation in the equipment, thereby accelerating the ion migration rate and effectively improving the desalination rate. The influent water in the EDI stage is the secondary reverse osmosis produced water, and the concentrated water produced after desalination by EDI technology can be returned to the primary reverse osmosis production tank to enter the next treatment stage.
The combination of these two technologies provides a strong guarantee for the quality of ultrapure water production, which can achieve continuous and stable production, and has the advantages of strong automation, low energy consumption and no pollution, and has been widely recognized in industrial production.
