Difference between ultrafiltration membrane water purifier and reverse osmosis water purifier

When our families buy water purification equipment, they must have been very carefully considered, because the functions of different water purification equipment are different. Only by purchasing a good and most suitable water purification equipment can we guarantee the water quality safety of our families. The two types of water purifiers widely favored by consumers are ultrafiltration membrane water purifier and reverse osmosis water purifier. What's the difference between the two kinds of water purifiers? You may not know much about it, so I'll give you a detailed introduction today.

Ultrafiltration membrane water purifier

Reverse osmosis water purifier adopts reverse osmosis membrane filtration technology. Reverse osmosis membrane is a selective permeable membrane, which can remove all dissolved heavy metal ions harmful to human body in water, other ions dissolved in water, and organic substances harmful to human body such as carbon tetrachloride and chloroform in water, as well as water in raw water The seeds are reserved for drinking, and the others, including bacteria, viruses, pollutants and scale, are discharged as concentrated water.

Ultrafiltration membrane water purifier adopts ultrafiltration membrane filtration technology. Ultrafiltration membrane purification technology is pure physical filtration. It relies on the micropores on the surface of ultrafiltration membrane for screening. It can filter suspended solids, particles, bacteria, colloids, viruses and other macromolecular substances in water, while retaining minerals beneficial to human body.

Ultrafiltration membrane water purifier -- difference of produced water quality

Both reverse osmosis water purifier and ultrafiltration membrane water purifier can provide drinking water up to the drinking water quality standard, but the water produced by reverse osmosis water purifier is better than that by ultrafiltration water purifier. Because the reverse osmosis water purifier can remove the harmful heavy metal ions dissolved in the water and the micro colloid and other pollutants, but the ultrafiltration technology can not remove the micro colloid and other pollutants.
The above is to introduce some working principles of ultrafiltration membrane water purifier and reverse osmosis water purifier and the difference of water quality. I hope you can understand that in our life, it is very important to have a good water purifier. Only by using the correct and appropriate water purifier can we provide a very good health guarantee for our domestic water 。

Which kind of water heater is safer and more comfortable to choose at home

What kind of domestic water heater is good? Newly decorated house, install water heater in bathroom, I don't know which one to choose. Electric water heater, gas water heater, solar water heater and air source water heater are all popular types of water heaters. The following are introduced to see which is your most satisfactory.

What kind of domestic water heater is good - electric water heater

At present, there are storage type traditional electric water heater and instant electric water heater, which meet the needs of different users. However, the electric water heater is prone to the danger of electric shock, and it completely depends on electric energy to heat, which is slow, unstable water temperature and large power consumption.

What kind of domestic water heater is good - gas water heater

Gas water heater is a type of water heater with mature technology. It can be heated quickly, without waiting, and it is easy to use. The water output is also relatively large, which can meet the needs of many people. However, after installation, it is necessary to ensure that it can be used in a well ventilated environment, otherwise poisoning accidents and explosion risk will occur.

What kind of household water heater is good - solar water heater

Solar water heater is to rely on solar energy to heat water, energy saving and environmental protection suitable for rural installation, urban area is not suitable for installation, but now there is a balcony dedicated solar water heater. It is not economical to use solar water heater in areas with insufficient illumination. Electric auxiliary heating can also be used, but the power consumption is relatively large. At least one third of the time in the use of electric heating, very inconvenient.

What kind of domestic water heater is good - air energy water heater

Due to the separation of water and electricity, the air energy water heater does not need the electric heating element to contact with water, so there is no hidden danger of electric shock, and it does not discharge any harmful body, so it is safe. The volume of the air energy water heater is also relatively small, and the water output is large, which saves more space than the traditional water heater. Also has the function of high temperature sterilization, can enjoy a cleaner bath to enjoy, let the bath become more healthy.

The above four common types of water heater, through the introduction of each aspect, we can find that each water heater has its own advantages and disadvantages. When selecting, users need to pay more attention to comparison, and choose according to their own actual needs. Comparatively speaking, air source water heater is a kind of water heater with more energy saving, environmental protection and higher safety performance. At present, the strength of market development is far from enough, and people's understanding is not in place. I believe that with the continuous popularization of air energy water heaters, and with the deepening of people's understanding, it will obtain greater development space in the future.

Introduction of different types of water heaters

In our family when buying water heater, I believe it will be combined with their own actual situation, to decide which kind of water heater to buy and install. However, some consumers are not particularly clear about the differences of various water heaters, so today I will introduce various types of water heaters for you to choose more conveniently.

The electric water heater is easy to use

There are two types of electric water heater: water storage type and instant heating type. The former is simple to install, constant temperature, low energy consumption, not affected by the height of the floor, not bulky, takes up more space, preheating time is long, need to wait, easy to scale, need to clean regularly, replace the magnesium rod. The latter has the advantages of fast water discharge, small volume and simple installation and use. However, the power is large, and the water yield is small when the water temperature is low in winter.
According to different classification standards, there are different types of gas water heater, no matter which type, generally speaking, it is in line with the actual situation of our country, and can meet the needs of people. Gas water heater has the advantages of high heating efficiency, fast heating speed, stable temperature regulation, continuous use for many people, low purchase price and low energy consumption. However, in the process of use, gas poisoning is easy to occur, so the safety is not very high.

Economic and environmental protection of solar water heater

Solar water heater is a kind of water heater which is usually assembled by vacuum heat collecting tube. As long as there is sunlight, it can generate heat. It is a kind of water heater with outstanding effect of economy, safety, environmental protection and energy saving. However, there are also some defects, such as easy to burst the vacuum tube, high installation cost, not low maintenance cost, easily affected by the climate, electric auxiliary heating in winter. It is easy to breed bacteria and microorganisms when water is still for a long time, and scale will be produced on the inner wall after long use.

Which water heaters are better - air water heaters are not restricted by the weather

Air energy water heater has the advantages of energy saving, environmental protection, safety, not limited by weather conditions, long service time, but the installation price is high, the volume is relatively large, and the selection requirements for installation are also very high. However, it can not be used in winter in the colder parts of the north.

The above is a small series for you to introduce several different types of water heater, there is no way to say which is absolutely good, but according to different circumstances we can choose different types of water heater to use, there is no best water heater, only the most suitable water heater is what we need.

The difference between pure water machine and water purifier

Nowadays, many users are not clear about the difference between water purifiers and water purifiers. Although water purifiers are a kind of water purifiers, it would be a big mistake to think of water purifiers as water purifiers. First of all, the big difference is that the filtration method of the water purifier is more scientific than the filtration method of the pure water machine. Next, I will talk about the differences between them.

The difference between water purifier and water purifier-safety

The filter material of the water purifier is selective. It can not only selectively filter the known substances in the established water quality, but also focus on the harmful substances; the water purifier does not selectively filter, and it filters everything.

The difference between pure water machine and water purifier-life adaptability

The human body needs clean and hygienic water, not pure water. Judging from this, the water purifier filters harmful substances and retains the mineral elements that are beneficial to the human body, making it more suitable for domestic water filtration; the water purifier filters everything, and the water contains almost no other substances, and the filtered water is not conductive, which is beyond In view of the characteristics of nature, the effect of long-term drinking of pure water without natural attributes on the human body needs further research. Therefore, the industrial use of pure water machines is more extensive.

The difference between pure water machine and water purifier-environmental protection

Water purifiers generally do not use electricity, and there is almost no waste water, so they are relatively environmentally friendly and low-carbon; water purifiers require electricity to be used, and must have at least 50% of waste water, so they are wasteful and not environmentally friendly.

The difference between a pure water machine and a water purifier-adapt to the water source

The water purifier is more suitable for municipal tap water sources and water sources with a clear degree of pollution; the water purifier is more suitable for unknown water sources and special occasions.

The difference between pure water machine and water purifier-cost performance

The price of water purifier is relatively cheap, the maintenance cost is low, and the cost performance is high; the water purifier is too complicated, the price is relatively expensive, the maintenance cost is also high, and the cost performance is low.

After comparison, we can see the obvious difference between water purifiers and water purifiers. They have their own advantages and disadvantages. When purchasing, you can decide whether to buy a water purifier or a water purifier according to your actual needs.

Which is better, a water purifier or a water softener

Among the many water purifiers, water purifiers and softeners are two of the more common ones. Many users are a little confused when choosing a water purifier. Which one is better? For this question, different users have different needs, so the answers given are also different. The following is a detailed introduction from the principle, function, advantages and disadvantages of water purifiers and water softeners.

The water purifier has good purification effect and long use time

The water purifier uses 0.01 micron ultrafiltration membrane separation technology, which can effectively remove harmful substances such as water, sand, rust, suspended matter, colloids, bacteria, viruses, and macromolecular organics. The filtration density of the water purifier is relatively high, and the water filtered by the water purifier, like mineral water, can be directly consumed. The flow of the water purifier is large, which can meet the demand of a large number of users. The filter element of the water purifier can be used for a long time, and can realize the effect of automatically cleaning the filter element to avoid secondary pollution.

The water purifier does not need to consume electricity, and at the same time, it does not produce waste water or waste. However, the water purifier also has some shortcomings. For example, for areas with hard water quality, the effect of removing scale and alkali is not good, and it is suitable for areas with medium hardness and below. The peculiar smell in the water cannot be completely eliminated, and the heavy metals in the water cannot be completely removed, so the taste of the water is relatively poor and it is not very good to drink. It is troublesome to replace the filter element of the water purifier.

Water softener can remove alkali and scale

According to the principle of ion exchange, the water softener uses Na+ to exchange Mg2+Ca2+ to reduce the hardness of the water to less than 70 mg/L to become soft water. The main function of this water treatment equipment is to remove alkali and scale. The water softener can remove the scale, and the water alkali is also no problem. When in use, the water output is relatively large, the water pressure will not be reduced, and the cleaning ability is strong. Daily drinking can be assured, and washing face, bathing, etc. can also protect the skin, beautify and nourish the skin. Used for washing clothes, etc., saving washing supplies and reducing the intensity of housework. The water produced by the water softener water treatment equipment is most suitable for domestic water. The water softener cannot clean bacteria, viruses, and organic matter directly, so it cannot be drunk directly. It needs to be boiled before drinking. Need to consume salt during regeneration; and produce a certain amount of waste water.

Through the above introduction, we can find that the difference between water purifier and water softener is quite big. For northern areas with serious scales, it is a good choice to choose a water softener to make the water purification effect more obvious. For the southern region, the water purifier can play a more ideal role.
