Industrial deionized water ultra pure water equipment

Industrial deionized water is mainly suitable for the purification treatment of surface water, groundwater, reservoir water, tap water and other water sources. Deionized water refers to water after removing impurities such as ions. It can be classified into three levels based on the content of impurities: the online conductivity of the produced water is less than 10 μ S/cm; The online conductivity of the produced water is less than 1 μ S/cm; The online conductivity of the produced water is less than 0.1 μ S/cm; Industrial water can be customized according to different practical uses to meet different needs. Permeation source deionized water equipment has wide applicability, stable effluent quality, and low cost. When the industrial water quality requirements are low, the effluent quality should reach a conductivity of less than 10us/cm, while when the requirements are high, the resistivity should reach 18.2M Ω.

Deionized water treatment equipment process:

Tap water → Multi medium filter → Activated carbon filter → Softener → Intermediate water tank → Low pressure pump → Precision filter → Primary reverse osmosis → PH adjustment → Mixer → Secondary reverse osmosis (with positive charge on the surface of the reverse osmosis membrane) → Pure water tank → Pure water pump → Intermediate water tank → EDI water pump → EDI system → Microporous filter → Water point

Industrial deionized water equipment process:

The first method is to use cation anion exchange resin to obtain deionized water. Generally, after passing through, the conductivity of the effluent can be reduced to below 10 US/cm, and then it can reach below 1 US/cm through a mixed bed. However, the water produced by this method has extremely high cost and too many particle impurities, which cannot meet the ideal requirements.
The second method is pre-treatment (i.e. sand carbon filter+precision filter)+reverse osmosis+mixed bed process. This method is currently widely used, and the investment cost of reverse osmosis is not high. Moreover, it can remove 90% of the ions that have already been added to the water, and the remaining ions can be removed through mixed bed exchange, which can make the effluent conductivity reach about 0.06. This is currently a popular method.
The third method is to use reverse osmosis membrane for pre-treatment, just like the second method. The difference is that the mixed bed used later uses EDI continuous desalination membrane blocks instead, which eliminates the need for acid-base regeneration resin and instead uses electric regeneration mode. This completely makes the entire process environmentally friendly and pollution-free, and the treated water quality can reach over 15M Ω. This method requires a significant initial investment, but the overall maintenance cost is extremely low, making it suitable for enterprises with significant growth.

Characteristics of Industrial Deionized Pure Water Equipment:

1. Continuous water supply: Adopting a dual tank configuration, one for use and one for backup, it can automatically switch to uninterrupted water supply.
2. effluent quality: The water quality is stable and excellent, and the effluent pH value is close to neutral. Short term changes in operating conditions (such as influent quality or composition, operating flow rate, etc.) have little impact on the effluent quality of the mixed bed.
3. Intermittent operation has little impact on the effluent quality, and the time required to restore the water quality to before shutdown is relatively short.
4. The equipment has a high degree of automation and can operate fully automatically without human supervision, saving labor costs.
Application scope:
It is mainly used for pre-treatment of boilers, thermal power plants, chemical, light industry, textile, pharmaceutical, biological, electronic, atomic energy and pure water treatment. It is also used in industrial production for hard water softening and deionized water preparation. It can also be used for decolorization and purification of food and drugs, recovery of precious metals and chemical raw materials, electroplating wastewater treatment, etc.
