What is the difference between ultrafiltration water purifier and reverse osmosis water purifier?

Ultrafiltration water purifiers can only filter coarsely, which can filter out large particles, sediment, etc. Only when your water quality is good enough, you can make do with it, the reverse osmosis water purifier almost removes all the impurities in the water during the manufacturing process, which is the original face of water, can be directly drunk raw, sweet and refreshing, and the benefits to the human body are many: (1) High solubility, the strongest affinity with human cells, and the effect of promoting metabolism.

2) It can eliminate the greasy in the human digestive system, eliminate blood lipids on the blood vessels, and reduce cholesterol. It is good for patients with high blood pressure, arteriosclerosis, and coronary heart disease. (3) When decocting Chinese medicine, it can brew the ingredients of the inherent medicine hidden in the herb without reservation, and the Chinese medicine can give full play to the medicinal properties.

Drinking purified water while taking the medicine will help the drug fully dissolve and absorb and improve the efficacy. (4) It can moisturize, eliminate secretions, maintain delicate luster, and is the cheapest beauty product. (5) Purified water can delay the absorption of ethanol, prevent diarrhea after drinking, and have an anti-hangover effect.

6) Brewing tea with pure water can properly adjust the dissolution of tannic acid, so that the tea color is bright, the tea taste is mellow, not only the taste is good, there is no tea rust, you can better experience the artistic conception of "three points of tea, seven points of water". (7) Cooking soup with purified water is delicious and delicious. (8) The use of pure water for automobile water tanks, humidifiers, electric irons, etc., will not scale and can prolong the service life.

9) It is used to raise fish, because of its high oxygen content and no chlorine gas, fish live better (10) Pure water is oxygen-rich water, which can activate cells and internal organs, and enhance immunity and resistance.

The upstairs is really nice. However, reverse osmosis water can only be called safe water for drinking.

Truly healthy water should be:

1.Safe and pollution-free (reverse osmosis water has done this).

2.It is rich in minerals and trace elements (reverse osmosis water is obtained after multi-layer filtration and reverse osmosis membrane (membrane) treatment, which is very clean and free of minerals and trace elements).

3.Water molecules are small molecules (only small molecules can pass through a hydrophilic channel of only 2 nanometers, enter the cell, activate the cellular enzyme system, activate tissue cells, promote microcirculation, improve the body's immunity, and is conducive to health and longevity. Reverse osmosis water, that is, pure water, does not have these and is not easily absorbed by the human body).

4.Weakly alkaline (Weakly alkaline water can help maintain acid-base balance in blood and body fluids, allowing the body to fight bacteria, viruses, inflammation, and disease more effectively.) Reverse osmosis water is acidic, and long-term drinking is not good for human health).

5.Negative potential (promotes metabolism and enhances human immunity).

6.Rich in active hydrogen (due to the large amount of active hydrogen, the redox potential of hydrogen-rich activated water can reach -400mV, with strong antioxidant capacity, can effectively scavenge oxygen free radicals; ）

Shenglian water purifier has one machine and two waters, and at the same time meets the concept of safe and healthy drinking water for families!

The latter can remove all harmful substances and is the safest.

From the point of view of filtration accuracy, reverse osmosis is better.

The reverse osmosis water purifier uses reverse osmosis membrane filtration, with a filtration accuracy of microns, equivalent to one millionth of a hair, and is currently the membrane with the highest filtration accuracy, with a service life of about 2 years.

Therefore, the manufacturing cost of this membrane is also expensive, and the inconvenience caused by it is that it needs to be plugged in, which will produce a certain amount of concentrated water. However, this part of the concentrated water can also be used to water flowers, flush toilets, etc., compared with the water wasted in bathing, the concentrated water produced by the water purifier is still very small.

Features of ultrafiltration water purifiers:

Through the high-precision physical purification process of ultrafiltration membranes, almost all sediment, rust, bacteria, visible suspended solids, algae and macromolecular organic matter can be removed from the water.

Most ultrafiltration machines use a three-layer structure such as pre-PP filter element, ultra-filter filter element, and post-activated carbon, in which the PP filter element needs to be replaced in about 3-6 months, and the life of the ultrafiltration filter element can be maintained for about 12-24 months according to the use.

The ultrafiltration water purifier itself does not need to be powered and does not produce waste water because it is filtered by the tap water's own water pressure.

The main differences: filtration accuracy and water purification effect.

The main difference between a reverse osmosis machine and an ultrafiltration machine is the filtration accuracy.

The filtration accuracy of the ultrafilter is mostly nanometers, with 1 micron PP cotton filter element and activated carbon filter element, it can filter out rust, sediment, bacteria, viruses, organic matter and bleaching powder above the particle size of nanometers, and can be directly drunk in areas with good water quality and no heavy metal pollution, but it is generally recommended that you boil the water before drinking.

The filtration accuracy of the reverse osmosis water purifier can reach microns, in addition to the above substances, it can also filter out metal ions and water-soluble salts, and the filtered water is almost pure water, which can be directly drunk, suitable for seriously polluted areas and users with high requirements for water quality.

The main difference: the wastewater rate.

The water purifier needs to discharge a certain amount of wastewater when making water, and a part of the water is consumed to flush the filter membrane. Generally speaking, there is not much waste water from ultrafiltration machine, and there is more wastewater from ordinary reverse osmosis machine, usually 1:3, that is, 3 parts of wastewater should be discharged to make 1 part of pure water.

Some brands claim to have a 1:3 ratio of wastewater, but in fact there is a ratio of 1:4 or 1:

5. Coupled with the water that rinses the filter membrane, the wastewater ratio even reaches 1:8 or even 1:10!

There is a lot of wastewater, and I am panicked! Not only does it cost money, but it also wastes the country's precious water resources!

Faced with the dilemma of the industry with too high wastewater rate, Oubiyuan focuses on the research and development of new technologies, breaks through the bottleneck of the industry, and launches the micro-wastewater technology with national invention patents, with a wastewater ratio of 3:1, and only 1 wastewater is discharged when producing 3 parts of pure water, which saves nearly 90% of water compared with ordinary RO machines. After the wastewater rate is reduced, the cost of water is also greatly reduced, and the cost per ton of water is only half of that of bottled water, saving money and worry.

Minor differences. 1. Effluent flow:

The effluent flow of the ultrafilter is large, about 60-70L per hour.

The reverse osmosis water purifier has a fine filtration structure, and the 50g model with the highest penetration rate on the market produces only water per hour. However, generally such water purifiers are equipped with water storage buckets, and the user's experience is the same for drinking. Of course, if you want to get a better drinking experience, you can choose a 400g high-flux reverse osmosis water purifier, which can produce 60L of water per hour, and can also save cabinet space.

2. **: The cost of the filter element of the reverse osmosis water purifier is high and the production process is complex, so it is higher than the ultrafiltration machine.

European high-end brand aquaphor water purification equipment authorized **Shangtai Ward (Beijing) Technology****.

Reverse osmosis is better.

1. Reverse osmosis and ultrafiltration, the core components are membrane elements. There are three main differences:

1) The pore size of the reverse osmosis membrane is only 1 100 of the ultrafiltration membrane, so the reverse osmosis water purifier can remove heavy metals, pesticides, chloroform and other chemical pollutants in the water, and the ultrafiltration water purifier is powerless to do so; The ultrafiltration water purifier can remove particulate pollutants and bacteria, reverse osmosis can remove all-round.

2) The effluent water quality and the testing standards of the health department are different, for example, the effluent bacteria index, the ultrafiltration water purifier is "general water quality processor", and the total number of colonies is 100 ml; The reverse osmosis water purifier is 20 ml, which is much stricter, and of course, the water quality of the reverse osmosis water purifier is much better than that of the ultrafiltration water purifier.

3) The reverse osmosis water purifier is a qualitative water supply, pure water for drinking, and concentrated water for washing; The ultrafiltration water purifier is generally used as washing water; It can also be used as drinking water when the tap water is of good quality.

2. The advantages of reverse osmosis water purifier are: water quality is safe, and it can remove various harmful impurities in the water; It has a good effect on water supply special events; The taste of the water is better; It can reduce the hardness of water, and the boiling water container does not scale;

Its disadvantages are: pump, power consumption, electrical safety problems; There are many joints, high water pressure, and the failure rate and water leakage probability are relatively high; The structure is complex and more expensive.

3. The advantages of ultrafiltration water purifier are: generally no pump, no power consumption, no electrical safety problems; There are few joints, low water pressure, and the failure rate and water leakage probability are relatively low; The structure is simple and cheap;

Its disadvantages are: poor removal of chemical contaminants in water; The effect on water supply special events is poor; The taste of the water is slightly worse; The hardness of the water cannot be reduced, and if the hardness of tap water is high, the boiled water container may be scaled.

Is it better to have ultrafiltration or reverse osmosis for water purifiers?

Both are very good, and Lisheng's after-sales service is guaranteed.

Reverse osmosis is recognized in the international community, which can remove all impurities, such as bacteria, heavy metals, etc., and meet the standard of drinking water. Water purifiers can generally only filter some macromolecular impurities, and some small molecular impurities such as viruses and bacteria cannot be filtered out, especially in areas with poor water quality. Reverse osmosis can be drunk directly.

The first one should be good, relatively clean, safe to use, recommended.

I think the water purifier is better than ultrafiltration.

Recommended for drinking ultrafiltration Water purifier Ultrafiltration retains various minerals required by the human body in the water, and the pH of the water is neutral.

Drinking reverse osmosis produced water for a long time can cause the loss of calcium and magnesium in the human body, and the water is weakly acidic.

You can't simply say which one is better, the main thing is to suit your needs and local water quality.

After understanding the different filter membranes, you will have a clear judgment yourself, and the following icon may be convenient for you to understand and help you choose.

Each is good in its own way, for the following reasons:

2. RO reverse osmosis:Filter out almost all harmful substances and residues in the water. Able to meet the standard of direct drinking. For some users, ** is slightly higher, there is wastewater, and electricity consumption is a hurdle that cannot be passed in the heart.

Reverse osmosis and ultrafiltration are both commonly used water purifier filtration technologies, and their main differences are in the filtration level and treatment effect.

Filtration level: Ultrafiltration is a coarser physical filtration method, the filtration pore size is generally about microns, which can filter out substances larger than bacteria, such as sediment, rust, fibers, etc., but cannot filter out some small molecules or ions, such as viruses, bacteria, heavy metals, pesticides, etc.

Reverse osmosis is a more detailed filtration technology, through high pressure reverse osmosis of water through the semi-permeable membrane, can completely filter out ions, organic matter, bacteria, viruses and other small substances in the water, to achieve a high water purification effect.

Treatment effect: Therefore, when choosing a water purifier, you should choose according to your actual needs. If it is only to filter out larger particles in the water, ultrafiltration can meet the demand; If high-quality purified water is required, reverse osmosis is a better option.

Water purifiers can be divided into three types: ultrafiltration, nanofiltration and reverse osmosis, and their differences are mainly reflected in the filtration accuracy, scope of application and **.

1. The filtration accuracy is different. The filtration accuracy of ultrafiltration membranes is generally between microns and 1 micron, which can remove harmful substances such as sediment, rust, and large particles of impurities in water, but cannot remove bacteria, viruses and other microorganisms. The reverse osmosis membrane filtration precision is microns, the good and bad will all be filtered, and after filtration, it is completely pure water, which can be directly drunk.

2. The scope of application is different. Ultrafiltration membranes can work under high pressures and can remove dissolved salts, colloidal substances, organic matter and various impurities in water, but cannot remove microorganisms such as bacteria and viruses. The reverse osmosis membrane can work at room temperature and has a wide range of applications, suitable for families, hospitals, enterprises and other places that require high water quality.

3. **Different. According to the different filtration accuracy and scope of application, the ** of ultrafiltration water purifier is generally less than 300 yuan, while the ** of nanofiltration membrane and reverse osmosis water purifier is usually more than 1000 yuan.

For safe water, RO reverse osmosis water purifier is preferred.

Facing ultrafiltration water purifier and reverse osmosis water purifier. First, when the tap water pollution is more serious, choose a reverse osmosis water purifier, which has a better filtration effect.

Second, families who need direct drinking need to choose a reverse osmosis water purifier can meet the requirements of direct drinking.

Third, in areas with better tap water quality, choose ultrafiltration water purifiers, which are more cost-effective and cost-effective.

The difference between the two is in:

The pore size of the membrane element, the pore size of the reverse osmosis membrane is only one percent of the ultrafiltration membrane, so the reverse osmosis water purifier can remove heavy metals, pesticides and chloroform and other chemical pollutants in the water, but the ultrafiltration water purifier cannot do this.

Ultrafiltration water purifiers can mainly remove particulate pollutants and bacteria from the water, but these reverse osmosis water purifiers can also do it. Both kinds of water purifiers have their own advantages and disadvantages, and they are not as strong as the one that is absolutely strong. The use of water purifiers depends on the local water quality.

For water sources with good water quality, such as municipal tap water, ultrafiltration water purifiers can meet the needs of daily life. For industrial pollution, reverse osmosis water purifiers can be used in areas where water quality is difficult to guarantee.

1. Advantages of reverse osmosis water purifier.

The reverse osmosis water purifier can remove all kinds of harmful impurities in the water, can be drunk directly, and the taste of the water is relatively good, which can effectively reduce the hardness of the water, and the container after boiling water does not produce scale. In addition, it is currently a relatively fine membrane separation product. The filtration method is reverse osmosis membrane, the filtration accuracy reaches microns, and electricity is used.

It can filter out sediment, rust, colloids, organic matter, bacteria, viruses and heavy metals. After filtration, the purity of the water source is high, and it can be drunk directly, but it is high, and there will be wastewater, which is suitable for all kinds of water quality.

Second, the advantages of ultrafiltration water purifier.

The ultrafiltration water purifier usually does not need a pump and does not consume electricity, and generally uses the normal water pressure of municipal tap water, which produces less wastewater and retains minerals and trace elements in the water.

If your city is polluted by heavy industry, it is best to choose a reverse osmosis water purifier with comparative insurance. The filtration accuracy of the reverse osmosis membrane of the water purifier reaches microns, which is one millionth of a hair, which can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water, and completely remove the water alkali and scale.
