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.

Talking about the difference between pure water machine and direct drinking machine

Water quality has become a big problem in today's society. In order to improve the water quality, there are many products, including pure water machine and direct drinking machine. What is the difference between these two products? Next, I'll give you an answer. Let's talk about the difference between the pure water machine and the direct drinking machine. Let's look at it together.

The difference between pure water machine and direct drinking machine

The direct drinking machine is a kind of device which can purify municipal tap water into direct drinking water, or at the same time, it can heat, cool and distribute the purified water by consuming electric energy.

Water purifier is a kind of water purification equipment which uses multi-stage filter element to purify water quality. The physical methods such as filtration, adsorption and reverse osmosis without adding chemical substances are used in the treatment. According to the water purification accuracy of water purifier, it can be divided into drinking water purifier, also known as household water purifier and laboratory water purifier which can meet the requirements of laboratory pure water quality.

Difference between pure water machine and direct drinking machine - different advantages

The water in the direct drinking water dispenser is purified and reaches the standard of direct drinking water. For example, the direct drinking water machine of runsuo in the United States adopts reverse osmosis low-pressure RO membrane filtration treatment. The purified water after treatment is fresher, safer and more hygienic than barreled water, which is also one of the biggest advantages of the direct drinking water machine. Direct water dispenser has strong water supply capacity. If you want to drink hot water and warm water, you can drink it at any time as long as the temperature is enough, which is simple and convenient. Direct drinking water dispenser will automatically cut off power when encountering electric leakage and other dangerous situations, so it is safer to use.

With RO reverse osmosis membrane as the core filter element, the water purifier has a filtration accuracy of 0.0001 μ m (1 mm = 1000 μ m), which can remove 100% of the secondary pollutants such as rust, colloid, organic matter, bacterial virus and other macromolecular substances in tap water due to pipe aging and water tank pollution. Only a small part of water molecules can pass through the filtration membrane to completely purify the water quality, Truly achieve pure effect. Generally, purified water will be equipped with pre activated carbon, post activated carbon and other filter elements to deeply purify, absorb impurities, and improve the taste, so as to drink more mellow directly.

Through the above description, we can better understand the difference between pure water machine and direct drinking machine, which will help people better choose their own products. We can know the difference between pure water machine and direct drinking machine through other ways. Because there are many products in today's society, it is very necessary to understand the differences between them.

Advantages and differences between pure water machine and ultrafiltration machine

The water purifiers and ultrafiltration machines that we will introduce today are the most mainstream products on the market. Their most important filter elements are filter elements and reverse osmosis technology. As a member of the water purification system family, what are their differences and advantages? In fact, the water purification system also includes water purifiers, central water purifiers and so on.

The difference between pure water machine and ultrafiltration machine-ultrafiltration machine

principle

Ultrafiltration is a pressurized membrane separation technology that allows small molecular solutes and solvents to pass through a special membrane with a certain pore size under a certain pressure, so that macromolecular solutes are impermeable and stay on one side of the membrane. Macromolecular substances have been partially purified. Ultrafiltration can be divided into three types: microfiltration, ultrafiltration and reverse osmosis according to the operating pressure applied and the average pore diameter of the membrane used. The operating pressure used by reverse osmosis is greater than that of ultrafiltration, often reaching 35×10^5 Pa～140×10^5 Pa. The average pore size of the membrane is the smallest, generally less than 10 angstroms. It is used to separate small molecular solutes, such as seawater desalination. , High-purity water, etc.

advantage

No waste water, no electricity, water can be discharged by tap water pressure, convenient and simple to use. At present, ultrafiltration membrane water purifiers are widely used in the south, especially in places with low scale. At the same time, water purifiers are also used as water purifiers for units, schools, banks, etc. These water purifiers are more effective, safer and more reliable to use, and ensure healthy drinking water.

Disadvantage

Incomplete filtration. If the water contains heavy metals and toxic and harmful substances, the ultrafiltration membrane will not filter thoroughly. At the same time, the problem is that the ultrafiltration membrane produced by some small manufacturers is of poor quality and it is difficult to guarantee the filtration effect. The membrane pores are not uniform. The filtering problem is also very serious.

The difference between pure water machine and ultrafiltration machine-pure water machine

principle

It is to filter the floating matter in the water, heavy metals, bacteria, viruses, etc. are removed. It has a higher filtration technology. Household water purifiers generally use four or five levels of filtration. The first level is a pp cotton filter element, and the second level and The third grade is activated carbon (a well-made manufacturer can combine the second and third stages into one), the fourth grade is RO reverse osmosis membrane, and the fifth grade is precision activated carbon, which is mainly used to improve the taste, so pure water machine comparison Suitable for areas with more serious tap water pollution.

advantage

Due to the small membrane pores, the filtration is thorough, which can effectively remove impurities, bacteria, viruses and other harmful substances in the water, and at the same time remove all heavy metals. The quality of the water coming out is pure water with better taste, which is widely used in medical and sanitation industries.

Disadvantage

The amount of waste water is large, electricity is required, and the installation is relatively complicated and troublesome. Because the water purifier adopts multi-stage filtration, the auxiliary filter element is frequently replaced, which causes the cost to rise, and it is easy to breed the hidden danger of secondary pollution. It is difficult to use a water purifier as a whole-house water purifier or a central water purifier because of its low water quality and flow rate, so the water purifier works better.

In addition to the filter elements of the two types of water purifiers introduced in the article today, other water purifiers such as ceramic filter elements are actually forbidden to be used abroad, because the filtering effect is not good, the cost is not high, and it is difficult to meet the water quality requirements. So if you want to buy a water purifier, you can use today's article as a reference.

The difference between water purifier and water softener

Water treatment equipment includes many types, including water softeners, water purifiers, and water purifiers. At the same time, they also perform their duties and each have their own specialties. Today, I will give you a brief introduction to the water purifier and water softener. What are the differences between water purifiers and water softeners, which are also water treatment equipment, and where are their respective areas of responsibility, can they replace the existence of one party? The following explains the difference between water purifiers and water softeners in detail!

Different structure

Water purifiers can be divided into vertical ultrafiltration water purifiers and horizontal ultrafiltration water purifiers according to different installation methods. The vertical ultrafiltration water purifier is composed of PP cotton, granular activated carbon, compressed activated carbon, external pressure ultrafiltration membrane, and T33; the horizontal ultrafiltration water purifier is composed of a stainless steel shell, an internal pressure ultrafiltration membrane, and KDF. The water softener is mainly composed of: multi-way valve controller, resin tank, strong acid cation exchange resin, water distributor, salt valve, salt tank, etc. The materials and structures of water purifiers and water softeners are very different, which leads to differences in the objects and scope of their use.

Different use

The water purifier is a Zhengzhou water treatment equipment that filters bacteria and impurities in the water. The main target of removal is: floating substances, heavy metals, bacteria, viruses, etc. As for water softeners, they are much simpler. Water softeners are Zhengzhou water treatment equipment used to soften water. They target hard water and target the magnesium and calcium ions contained in hard water.

Different working modes

The water purifier uses five-stage filtration technology to process water into water that can be used for human consumption. The five-stage filtration is: the first stage is a filter element, also known as PP cotton; the second stage is granular activated carbon; the third stage is precision compression Activated carbon; the fourth grade is reverse osmosis membrane or ultrafiltration membrane; the fifth grade is post activated carbon, mainly used to improve taste. Compared with the water purifier, the water softener also uses five processes to achieve the water purification function and soften the hard water. The five processes are divided into: work (sometimes called water production), backwash, salt absorption (regeneration), slow flushing ( Replacement), fast flushing five processes.

The above is the difference between a water purifier and a water softener. The difference between the two types of water purifiers is very big. Carry out a detailed investigation of the water quality and purchase water treatment equipment under the guidance of professionals.
