Why use high purity water machine and ultra pure water machine

The water purifier and the ultra-pure water machine can be distinguished from the name first, the water purifier is used to produce pure water, and the ultra-pure water machine is used to produce ultrapure water. Due to the different standards of water production, the water production process is different. Different from the water purifier, the ultrapure water machine is equipped with a purification column behind the reverse osmosis membrane, and the purification column is used to further desalinize the pure water produced, and finally reach the national standard for laboratory water and the first-class water standard.

The water purifier is a five-stage filtration method, which mainly filters out all the harmful substances in the tap water, and the water that comes out is pure water that can be drunk, which is equivalent to the pure water sold on the market, and cannot be used in the experimental process.

What is the difference between a water purifier and an ultrapure water machine?

The effluent quality of the ultra-pure water machine is higher than that of the purified water machine, the purified water machine is mainly a multi-stage filter element to optimize the water quality of the equipment, the water production process of the pure water purifier does not need to add chemicals, the pure physical filtration adsorption and reverse osmosis method is adopted, the pure water machine mainly has a drinking water purifier, which is also called a household water purifier, and a pure water machine that meets the requirements of the laboratory, that is, a laboratory pure water machine. The ultra-pure water machine mainly adopts pretreatment technology, reverse osmosis technology and ultra-purification treatment. It can remove the conductive medium in the water very thoroughly, and can also reduce the colloidal in the water to a minimum, the resistivity produced by the ultrapure water machine is greater than 10 trillion under normal circumstances, and the water above 10 trillion is called ultrapure water, and the effluent quality of the general ultrapure water machine can reach more than 18 trillion ohms.

How to choose an ultrapure water machine needs to consider the model, power, voltage, working pressure, sterilization rate, type, water temperature and other factors, such as ultraviolet germicidal lamps, ultraviolet disinfection lamps, materials, etc.; The models include SSY-UP, SSY-UPH, SSY-UPJ, SSY-UPII, etc.; The rated voltage is 220V, 380V, etc. Wait. The ** of ultrapure water equipment is about 20,000 yuan per unit, and the expensive ones are more than 100,000 yuan.

Before you choose, it is recommended to consult "Water Think" to let you fully understand the characteristics of ultrapure water machine for your reference.

1. LCD screen, real-time animation display of water production process.

2. The system adopts PLC control + PCB series module control.

3. Two-stage pretreatment column filtration is used to effectively remove particles and organic matter in water, and the replacement is simple and convenient.

4. The main machine adopts an integrated design, with compact structure and small footprint.

5. It has the functions of water quality exceeding the standard discharge, consumables replacement time prompt, and regular water intake, so that the equipment operation is more stable.

6. The system has strong fault diagnosis ability, and can predict alarms and instructions according to parameters such as pressure and water quality.

The expensive one must be the best.

The choice of ultrapure water machine needs to be comprehensively considered according to your own needs and actual situation, which can be used as a reference from the following aspects:

1.Water production capacity: When choosing an ultrapure water source to start, it is necessary to consider the water production capacity according to factors such as household population and drinking water volume, generally speaking, the water production capacity of household ultrapure water machine is between 5-15 liters per hour.

2.Filter element type: The type of filter element of ultrapure water machine affects its filtration effect, and the common types of filter elements are reverse osmosis, ultrafiltration, nanofiltration, etc., among which the filtration effect of reverse osmosis membrane is the best, but it is also relatively high.

3.Maintenance cost: The filter element of the ultrapure water machine needs to be replaced regularly, so you need to consider whether the maintenance cost is suitable for your financial affordability. Generally speaking, ultrapure water machines with relatively low filter consumables** are more economical and practical.

4.Ease of operation: When choosing an ultrapure water machine, it is necessary to consider whether it is convenient to operate and maintain, in addition, the capacity of the water storage tank and the automatic water dispensing function are also factors that need to be considered.

5.Product quality: When choosing an ultrapure water machine, you need to choose a brand with reliable quality, so as to ensure that the water quality is clean and healthy, and it is more safe to use.

Considering the above factors, choosing an ultrapure water machine should be more scientific and reasonable, so that your home drinking water is more secure.

Six key points for purchasing ultrapure water machine:

The choice of ultrapure water machine is mainly based on budget, brand, pure water process, water quality needs, water consumption, and application.

1. Pre-spine calculation: buy according to your actual budget before purchasing, choose the right product for yourself, and avoid overspending consumption. Foreign brands of water purifiers are expensive, generally about 50% higher than domestic brands, and cottage brands are cheaper, but the quality cannot be guaranteed.

2. Brand: After knowing our budget, now we have to consider which brands of ultrapure water machine brands to choose. There are many domestic and foreign brands, so you can choose the right brand according to your budget.

3. Pure water process: The distilled water process has been abandoned by most laboratories, because the water quality produced is not high, which is time-consuming, laborious and costly, resulting in unsatisfactory laboratory results. At present, most of the reverse osmosis process is used to produce water quality that can meet national standards, and is being used by most laboratories.

And now the process of domestic water purifier can be comparable to that of foreign brand water purifier, and our technology is not inferior to them, and some processes are even better than them.

4. Water quality requirements: purchase the specific model of ultra-pure water machine. For example, if the tap water you use locally is the water source, then the UPT and UPD series of water purifiers can be satisfied; If your local water source is underground well water, then the UPR series is sufficient.

5. Water consumption: The purpose of the machine is determined by Hayano Yuan, you can choose according to the daily water consumption of the laboratory, and the specific water output per hour is 5L-90L different models.

6. Application: After the water source problem is solved, you can consider it according to your own water needs, for example, your experimental water is mainly pure water, or you need ultrapure water, or both, at this time we can choose the machine of pure water outlet, or the machine of ultrapure water outlet, or the machine of double outlet.

How to distinguish between ultrapure water equipment and pure water equipment:

1.The working principle of pure water equipment is to exert a certain pressure on the water, so that the water molecules and ionic mineral elements pass through the reverse osmosis membrane, and most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses and other dissolved in the water cannot penetrate the reverse osmosis membrane, so that the permeated pure water and the impenetrable concentrated water are strictly separated.

The pore size on a reverse osmosis membrane is only microns, while the diameter of viruses is generally microns, and the diameter of ordinary bacteria is microns. The water flowing out of the pure water equipment meets the drinking water standard.

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

2.Different water quality standards: the effluent quality of pure water equipment generally meets the latest version of the "New Standard for Industrial Drinking Water", while the water quality of ultrapure water equipment has relatively strict requirements, generally according to the particularity of the industry, the selection of conductivity of 12m m m m, and other different levels of ultrapure water equipment.

Pure water No. 1 water treatment: There is no essential difference between ultrapure water equipment and pure water equipment, the principle is the same, but the process used is slightly different. The difference between ultrapure water and pure water is the resistivity, and it is generally called ultrapure water if it exceeds or approaches this limit.

The conductivity of produced water is different, the conductivity of pure water is between 2-10us cm, and the conductivity of ultrapure water is ; Heavy metals, bacteria, particle number and other indicators are also very different, pure water impurity content is ppm level, while ultrapure water is ppb level, simply said that there are no impurities in the water produced by ultrapure water equipment, close to theoretical water; The areas used are also different.

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

Pure water equipment, which uses mainly reverse osmosis membrane technology. Its working principle is to apply a certain pressure to the water, so that the water molecules and ionic mineral elements pass through the reverse osmosis membrane, and most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses and other inorganic salts dissolved in the water cannot penetrate the reverse osmosis membrane, so that the permeable pure water and the impermeable concentrated water are strictly separated; The pore size on a reverse osmosis membrane is only microns, while the diameter of viruses is generally microns, and the diameter of ordinary bacteria is microns.

The pure water equipment adopts advanced reverse osmosis technology, and its working principle is to apply a certain pressure to the water, so that water molecules and ionic mineral elements pass through the reverse osmosis membrane. Most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in water cannot penetrate the reverse osmosis membrane, so that the permeable pure water and the impermeable concentrated water are strictly separated.

Ultrapure water equipment is based on reverse osmosis technology, adding ion exchange and terminal treatment technology, and some also have advanced ion desalination, ultrafiltration and UV photooxidation equipment. Remove as thoroughly as possible the common soluble inorganics, organic matter, particulate matter, microorganisms, soluble gases and other impurities common in natural water.

The effluent quality of pure water equipment generally meets the new version of the "New Standard for Drinking Water".

The water quality of ultrapure water equipment has relatively strict requirements, generally according to the particularity of the application industry, the conductivity needs to reach 12mq, 15mq, 17mq, 18mq, and other different levels of ultrapure water.

The pure water equipment adopts the reverse osmosis process, the pressure exerted on the water, the water passes through the reverse osmosis membrane with a pore size of only microns, and filters out the impurities such as viruses and bacteria in the water or microns.

The commonly used process methods of ultrapure water equipment include distillation, reverse osmosis, ion exchange, filtration, adsorption, ultraviolet oxidation, etc., and the water purification process is roughly divided into four steps, pretreatment (primary purification), reverse osmosis (production of pure water), ion exchange (can produce ultrapure water) and terminal treatment (production of ultrapure water that meets special requirements).

To distinguish the difference between pure, high-purity and ultrapure water in the water treatment industry, the main thing is to look at their respective conductivity and salt content.

1. Pure water: pure water, also known as pure water, deionized water, refers to the water that meets the sanitary standards of drinking water as the raw water, through the electrodialyzer method, ion exchanger method, reverse osmosis method, distillation method and other appropriate processing methods, the preparation of sealed in the container, and does not contain any additives, colorless and transparent, can be directly drunk water, can also be called pure (chemically), used more in the test, and because it is made by distillation and other methods, it is also called distilled water. The best space water and distilled water on the market are pure water; However, it is better to drink less pure water, because it does not contain too many minerals that the human body needs.

Pure water does not conduct electricity easily and is an insulator. Lead-acid batteries should be rehydrated with pure water.

2. High purity water: High purity water is water with extremely high chemical purity, in which the content of impurities is less than. At present, the purity of high-purity water made by people has been reached, and the impurity content of it is lower.

High-purity water mainly refers to water with a temperature of 25, a conductivity less than , a pH value and the removal of other impurities and bacteria.

High-purity water refers to water that removes almost all the conductive media in the water, and removes the colloidal substances, gases and organic substances that do not dissociate in the water to a very low level. The salt content of high-purity water is below and the conductivity is less.

3. Ultrapure water: water with an ultrapure water resistivity of 18m*cm (25). It is often used in the integrated circuit industry for the cleaning of semiconductor raw materials and utensils, the preparation of photolithography masks and the water vapor source for silicon wafer oxidation.

In addition, ultrapure water is used in the production of other solid-state electronic devices, thick and thin film circuits, printed circuits, vacuum tubes, etc.

Pure water equipment is generally only the RO system, and the ultrapure water is generally added with EDI, mainly because of the difference in effluent quality. The general conductance of the RO effluent monopole is about 10, and the two-stage can be less than 5. Ultrapure water requires a resistivity of more than 10 general.
