Is the filter element of reverse osmosis water purifier universal?

Yes, but not as good as the original, good is the original good, you can look at Lawrence, Switzerland, in fact, it is also very good.

The RO membrane of reverse osmosis is generally general, as for the pre-filter element, most of them are now ten-inch standard filter elements, or Korean quick-connect filter elements, and some are snap-on filter elements, the same type can be replaced, different types, you can only find a machine to ask you.

Hello, As far as I know, the water filtered by reverse osmosis is pure water, that is, white water and distilled water.

A few years ago, two couples in Shanghai did not want to have children and tap water, so they began to enter a large number of Master Kong mineral water (purified water) on the day of pregnancy, and then their children could not speak or walk at the age of three, and went to the hospital for hypochondriasis.

After investigation, it turned out that Master Kong mineral water has no minerals, it is pure water, and children cannot get nutrients from water (newborn children get nutrients from water and milk) ( What do you think of ordinary water purifiers.

Can the water filtered out by reverse osmosis meet the needs of the human body On July 10, 2000, Guangzhou** was logged out"Purified water should not be drunk in large quantities for a long time, and experts remind infants, young children and adolescents to be especially cautious"reports.

The all-round water purifier of the times has nine cores and sixteen levels of filtration, you may not know, whether there are viruses, microorganisms and bacteria, how to look down.

The first transparent PPF fiber core (PP film).

Filters large particles of impurities in the water and reduces the turbidity of tap water.

The second is precision activated carbon.

Filter. Filter water from odors, discoloration, organic chemicals, pesticides, pesticides.

and chloroform (a strong carcinogen) and residual oxygen to improve water quality.

The third CTO activated carbon core.

The effect is the same as the second one).

The fourth hollow fiber ultrafiltration membrane.

Filter water from sediment, rust, bacteria, viruses, parasites.

Admit that ultrafiltration membranes can't filter out all bacteria).

The fifth channel is a nano-far-infrared photon generator.

Transmits far-infrared rays.

Sterilization and disinfection are followed by disturbing the large molecule water to produce small molecule water (small molecule water can enter the cell and supply the cell).

The sixth way is the nano high energy generator.

High-tech patented multi-composite materials are used"Totipotent nanologins"It can generate small molecule water, activate water quality, and so on.

The seventh course: Muyu Stone Maifan Stone.

Muyu stone and maifan stone have strong adsorption capacity, which can adsorb heavy metals in water and release more than 50 kinds of trace elements.

The eighth path is negative potential.

It causes a large amount of negative potential (mainly negative oxygen ions) to be generated in the water

The ninth path is small T33

It further adsorbs residual fine organic matter, completely removes odors, improves taste, makes water quality more delicious, and is convenient for direct drinking.

That's what I know, thank you.

The water made by the reverse osmosis water purifier has a filtration accuracy of microns, only water molecules can pass through, and the application of aerospace technology makes the water close to pure water, but the trace elements still exist, and it is the healthy water that the human body needs!

The effluent after a simple reverse osmosis device cannot be purified because reverse osmosis cannot remove hardness ions (scale) from the water alone.

Each has its own advantages and disadvantages, and it is best to choose according to the quality of local tap water.

If the local tap water quality is acceptable, you can also buy an ultrafiltration water purifier. But the filtered water must be boiled before it can be drunk. Because the water filtered out by the ultrafiltration water purifier has not yet reached the level of pure water, but the ultrafiltration water purifier does not need to be electrified, and no wastewater is generated.

The reverse osmosis water purifier filters out pure water, which has neither harmful substances nor beneficial substances, and can be drunk directly. However, the reverse osmosis water purifier not only needs to be powered to use, but also produces a large amount of wastewater, which is not suitable for long-term drinking in large quantities. It is suitable for purchase and use in places where the local tap water quality is very poor or there is secondary pollution.

Now many manufacturers have launched both pure water outlets, which can be directly drunk, and purified water outlets, which can be used for boiling water for cooking.

No matter what kind of water purifier you buy, all kinds of filter elements in it must be replaced regularly, otherwise the water purifier will become a dirt collector, which is harmful to human health.

For example, the service life of PP cotton filter element is 3-6 months, the activated carbon filter element is 6-12 months, the reverse osmosis filter element is about 24 months, and the ultrafiltration filter element is between 24-36 months.

The user must change the filter element regularly according to the quality of the local tap water and the amount of water used.

This problem needs to look at the local water quality situation to choose, can not say which is good and which is not good, the filtration accuracy of the ultrafiltration water purifier can reach microns, can filter out most of the impurities in the water, but for the area with relatively large water alkali, it is impossible to remove the water alkali, and the filtration accuracy of the reverse osmosis water purifier can reach microns, basically only water molecules can pass, so the filtration is basically pure water, and the boiled water is not water alkali, so it is recommended that you choose a reverse osmosis water purifier with double water outlet, This water purifier can make purified water and mineral water, which can meet different needs such as cooking and making tea, respectively.

It is able to remove all kinds of harmful impurities.

The water tastes good.

It can reduce the hardness of water, and boiling water is not easy to produce scale.

But his ** is generally more expensive.

The ultrafiltration water purifier does not use a pump and does not consume electricity, which is relatively safe and has a low failure rate.

But the water purification effect is not good.

So reverse osmosis is better.

I think reverse osmosis should be better, because most homes have to use this kind of water purifier.

With the increasingly serious environmental protection problems, people pay more and more attention to health, from the drinking water aspect, generally buy a water purifier to drink healthy pure water. There are two types of water purifiers on the market, one is reverse osmosis, and the other is ultrafiltration, so which of the two is better? The following is a detailed introduction, let's take a look.

With the increasingly serious environmental protection problems, people pay more and more attention to health, from the drinking water aspect, generally buy a water purifier to drink healthy pure water. There are two types of water purifiers on the market, one is reverse osmosis, and the other is ultrafiltration, so which of the two is better? The following is a detailed introduction, let's take a look.

First, let's look at the difference between reverse osmosis and ultrafiltration. (1) The effluent water quality is different from the testing standards of the health department, to give you an example, the effluent bacteria index, ultrafiltration water purifier according to the "general water quality processor", the total number of colonies is 100 ml; However, the reverse osmosis water treatment equipment is 20 ml, the requirements are more stringent, of course, the effluent quality of the reverse osmosis water treatment equipment should be much better than that of the ultrafiltration water purifier. (2) Reverse osmosis water treatment equipment is a separate water supply, pure water is provided for drinking, and concentrated water is used for washing; Ultrafiltration water purifiers are usually used as washing water; When the tap water quality is relatively high, it can also be used as drinking water ultrapure water equipment.

Let's look at the introduction of the advantages and disadvantages of the two. (1) The advantages of ultrafiltration water purifier are: usually no pump, no power consumption, no electrical safety problems; There are few joints, small water pressure, and the failure rate and water leakage probability are relatively low; Simple structure, affordable and affordable; The disadvantages are:

The removal of chemical contaminants in water is not effective; It is not effective for water supply special events; The taste of the water is not good; The hardness of the water should not be reduced, and if the hardness of the tap water is high, the boiling water container may become fouled. Ultrafiltration membrane can remove macromolecules, colloids, proteins, particles, etc. in the solution, and has the characteristics of low pressure, large water production and convenient operation. By testing the purification effect of the hollow fiber ultrafiltration membrane device for deep purification of the raw water for liquor production, it is shown that the ultrafiltration membrane water purification device can effectively eliminate the secondary pollution of water in the pipe network and further improve the water quality.

2) The advantages of reverse osmosis water treatment equipment are: water quality is safe, and it can effectively remove all kinds of harmful impurities in water qualityIt has a strong effect on water supply special events;The taste of the water is better;It can effectively reduce the hardness of water quality, and the boiling water container is not good for scaling;Its disadvantages are: pump, power consumption, electrical safety issues;There are many joints, high water pressure, and the failure rate and water leakage probability are relatively highThe structure is more complex and more expensive.

In short, reverse osmosis and ultrafiltration are both methods of water purification, and due to the different principles of action of the two, the effects and wide range of applications are also different. So, which of the two is better?We can't make a conclusion, it still depends on the actual water quality and the actual needs of the buyer, what we have to do before buying is to grasp the advantages and disadvantages of the two, and choose a more suitable one for ourselves based on our own needs.

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 drunk directly, which is 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 also 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****.

Ultrafiltration water purifiers cannot be directly drinkable, because the filtration accuracy of ultrafiltration water purifiers is microns, which is coarse filtration, which can filter out harmful substances such as heavy metals. Of course, it can be drunk after boiling. The reverse osmosis water purifier can be drunk directly, and the reverse osmosis filtration accuracy is microns, which can filter out heavy metals.

Why emphasize heavy metals, because heavy metals are very harmful to the human body. If you are in the northern region, it is recommended that you must use a reverse osmosis water purifier.

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

First of all, ultrafiltration and reverse osmosis are two types of filtration technologies.

1. Ultrafiltration (UF): The filtration accuracy is in microns, which is one of the high-tech technologies in the 21st century. It is a membrane separation technology that uses differential pressure, which can filter out harmful substances such as rust, sediment, suspended solids, colloids, bacteria, macromolecular organic matter and other harmful substances in water, and can retain some mineral elements that are beneficial to the human body.

It is the core component in the production process of mineral water and mountain spring water. The ** rate of water in the ultrafiltration process is as high as more than 95%, and it can be easily flushed and backwashed, not easy to clog, and has a relatively long service life. Ultrafiltration does not need to be pressurized, and can be filtered only by relying on tap water pressure, with large flow and low cost, which is more suitable for the comprehensive purification of household drinking water.

2. Reverse osmosis (RO): The filtration accuracy is about microns, which is an ultra-high-precision membrane separation technology using pressure difference developed in the early 60s in the United States. It removes almost everything from water (both harmful and beneficial) and allows only water molecules to pass through.

In other words, in the process of making water with reverse osmosis membranes, nearly 50% of tap water will be wasted.

Ultrafiltration water purifiers only have 3 to 5 layers of physical filtration, no reverse osmosis technology, so there is no reverse osmosis membrane, and of course there is no need for a pump. Filtration relies on water pressure, which is direct filtration, without the need for a water storage bucket. **Comparatively cheaper. No electricity.

In addition to the physical filtration of the ultrafiltration water purifier, the reverse osmosis water purifier also uses reverse osmosis technology, with a reverse osmosis membrane, a booster pump, and a water storage bucket, but at the same time, some water that is only physically filtered (can be used to wash clothes, etc.) will be discharged in the process of water production. This is the kind of one I have at home (the pump broke down recently, the warranty was over, and the after-sales price was 400, but I bought a 100 from the Internet and replaced it myself). **Relatively expensive.

To use electricity. It is recommended that if you have rice, you should buy reverse osmosis.
