Ultrapure water has a high application value in industrial production and is an indispensable raw material in the production of many fields, such as the production and cleaning of chips, picture tubes, phosphor screens, liquid crystal displays, picture tubes, batteries, etc. The reason why ultrapure water can be widely used in industrial production is because of its high purity, simple composition, basically no other elements except hydrogen atoms and oxygen atoms, which has almost no impact on the production quality of industrial products, and can fully guarantee the product quality.
The production process of ultrapure water is strict, and simple filtration, activated carbon adsorption, sterilization, etc. cannot make its water quality meet the requirements, and professional ultrapure water equipment is required to meet the production standards. "Reverse osmosis + EDI + polishing mixed bed" together constitute the production process of ultrapure water equipment, which can complete the production of ultrapure water with quality and quantity.
Reverse osmosis technology adopts reverse osmosis membrane technology with high filtration precision, good water permeability effect and strong anti-pollution ability, which can realize the separation and removal of nanoscale impurities in ultrapure water. It does not require chemical reagents and only needs to be driven by applying pressure on the inlet side to drive ultrapure water filtration. In this way, impurities such as organic matter, metal ions, minerals and microorganisms that need to be removed can be effectively removed from ultrapure water. The reverse osmosis membrane is not easy to be polluted, easy to clean, strengthens the resistance of ultrapure water equipment, and prolongs the service life of the equipment.
EDI is a treatment technology to achieve deep desalination of ultrapure water, which can realize charged operation, accelerate the ion migration rate, and make the desalination effect in the production process of ultrapure water more prominent. In addition, the EDI treatment process will not produce any acid and alkali waste liquid, no environmental protection burden, avoid the trouble of acid and alkali neutralization reaction to treat wastewater, and improve the production efficiency of ultrapure water.
Reverse osmosis technology and EDI technology are the dominant technologies in ultrapure water equipment, and the polishing and mixed bed technology strengthens the effluent quality of ultrapure water equipment and sets the level of production quality for ultrapure water. With these strong technical support, ultrapure water equipment has the comprehensive advantages of stable production, simple installation, strong automation and high effluent quality, and can serve industrial production with quality and quantity.
