What is the use of ultrapure water equipment in the electronics industry?

The advanced technology of EDI high-purity water equipment.

No chemical regeneration agents are required, and there is no pollution in the production process, which is a clean production;

There is no need to stop for regeneration, and continuous production of high-purity water with stable water quality (15 18m cm);

Stable and reliable operation, simple maintenance and low operating costs;

It occupies a small area and saves the cost of site construction.

The main role and scope of application of EDI high-purity water equipment.

The role of EDI is to remove salt. Under the premise of using RO permeate water to remove 97 99% ions, EDI can directly purify reverse osmosis permeate to the standard of pure water, high-purity water and ultra-pure water, without the use of ion exchange mixed bed, and the resistivity of the permeate can reach up to 18 m cm.

EDI equipment has a wide range of applications in industries with high water quality requirements. In the electronics industry, scientific research laboratories, inspection and analysis industries commonly used EDI to produce ultrapure water above 18 cm , in the fine chemical, power generation, electroplating industry commonly used EDI to produce more than 15 cm of high-purity water, in hospitals and pharmaceutical industry commonly used EDI to produce more than 5 cm of purified water, in the food and beverage industry to use EDI to produce more than primary pure water, etc.

Ultrapure water equipment for the electronics industry can make the water quality more stable, can efficiently remove various salts in the water, and the desalination rate can reach 99%, fundamentally improve the quality of water quality, and extend the working cycle, helping enterprises to achieve stable production.

Process flow of ultrapure water equipment for electronics industry:

Water source inlet -- raw water storage tank -- multi-media filter -- activated carbon filter -- scale inhibition device -- 5 micron precision filter -- two-stage reverse osmosis pure water unit -- reverse osmosis water storage tank -- EDI ultra-pure water production unit -- ultra-pure water storage tank.

Ultrapure water equipment for the electronics industry is used in the production of batteries.

Because the electrolyte in the battery is equipped with very strict requirements for pure water. The electrical conductivity of water is usually required to be above 10 trillion ohms.

The battery industry has a high demand for water, so when choosing water treatment equipment, it will choose the equipment with the best effluent quality, and ultrapure water equipment has become its preferred target.

Electronics, semiconductors, liquid crystal displays and other industries often need to use extremely pure ultrapure water in the production process. If the water quality does not meet the requirements of the production process water or the water quality is unstable, it will affect the treatment effect and service life of the subsequent process, so the quality of the water is very important. Ultrapure water equipment has a good effect in purifying water quality, and it is the water treatment equipment that many enterprises will choose.

Ultrapure water equipment generally includes pretreatment system, reverse osmosis device, post-treatment system, cleaning system and electrical control system.

The pretreatment system generally includes a raw water pump, a dosing device, a quartz sand filter, an activated carbon filter, a precision filter, etc. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine, and meet the inlet requirements of reverse osmosis. The equipment configuration of the pretreatment system should be based on the specific conditions of the raw water.

The reverse osmosis device mainly includes a multi-stage high-pressure pump, a reverse osmosis membrane element, a membrane shell (pressure vessel), a bracket and so on. Its main function is to remove impurities in the water, so that the quality of the produced water meets the requirements of use.

The aftertreatment system is an added configuration in cases where reverse osmosis does not meet effluent requirements. It mainly includes one or more types of equipment such as yin bed, yang bed, mixed bed, sterilization, ultrafiltration, EDI, etc. The post-treatment system can better improve the quality of the reverse osmosis effluent to meet the requirements of use.

The cleaning system is mainly composed of cleaning water tank, cleaning water pump and precision filter. When the reverse osmosis system is polluted, the effluent index cannot meet the requirements, and the reverse osmosis needs to be cleaned to restore the efficacy.

The electrical control system is used to control the normal operation of the entire reverse osmosis system. Including instrument panels, control panels, various electrical protection, electrical control cabinets, etc.

The above systems together form a complete set of ultrapure water equipment, the purity of the industrial pure water prepared by the ultrapure water equipment can reach 18m·cm, and the system is stable, the service life is long, and the wastewater generated in the production process can be reused and regenerated, energy saving and environmental protection.

Jingderui has the answer for you:

Nowadays, there are three main types of ultrapure water system processes, and the other processes are basically derived from different combinations and collocations on the basis of these three categories. The advantages and disadvantages of these three processes are now listed here.

1. The first process used by EDI electronic special ultrapure water equipment mainly uses ion exchange resin, and the advantages show that the investment is less and the place occupied is not very large, but the disadvantages are also very obvious, and it must be regenerated frequently, which has a certain damage to the environment.

2. The second process uses reverse osmosis technology as a pretreatment device technology, the shortcomings of this process are more serious than the previous process, and the initial investment is much higher than the previous one, and the only advantage is that the regeneration time interval of EDI electronic special ultrapure water equipment is relatively long, and there is also a certain degree of pollution to the environment.

3. The third process is also to use reverse osmosis as a pretreatment equipment, and the third method is the most economical and environmentally friendly process for producing ultrapure water, without equipment regeneration, and the surrounding environment is basically pollution-free. However, the disadvantage is that the capital investment is still too high compared to the above two methods.

Ultrapure water equipment is actually pure water equipment, because pure water is said to be water without impurities, but the process used is different, generally speaking, reverse osmosis water also belongs to pure water, pure water is just a general term.

The difference between ultrapure water equipment and other equipment is mainly due to the different processes, the industry generally calls the water treated by EDI equipment or mixed bed treatment process called ultrapure water, and the equipment that adopts sterilization and sterilization system in the equipment and meets the GMP requirements is called purified water equipment, and only the water treated by reverse osmosis process is called pure water equipment.

Ultrapure water equipment is a kind of water treatment, which adopts pretreatment, reverse osmosis technology, ultra-purification treatment and post-treatment methods to remove the conductive medium in the water almost completely, and remove the colloidal substances, gases and organic substances that do not dissociate in the water to a very low level.
