Water is the source of life, so how can the water purifier without a unified standard be absolutely

There is no absolute safety, there is no absolute thing in this world, and the water purifier can only greatly reduce the harmful substances in the water and purify the water quality to the greatest extent.

Water purifier, also known as water purifier and water purifier, is a water treatment equipment that carries out deep filtration and purification of water quality according to the requirements of water use. The water purifier that we usually talk about generally refers to a small purifier used for home use.

The core of its technology is the filter membrane in the filter element device, and the main technologies are ultrafiltration membrane and RO reverse osmosis membrane. The water purifier can effectively filter out rust, sand and gravel, colloids in the water, and adsorb residual chlorine, smell, discoloration, pesticides and other chemicals in the water. It can effectively remove bacteria, germs, toxins, heavy metals and other impurities in water.

The application of water purification technology in the field of drinking water makes the phenomenon of "water and soil adaptation" quickly become a thing of the past, and effectively solves the endemic diseases caused by excessive harmful substances in groundwater in many places.

According to the pipeline design level, it can be divided into two categories: gradual tightening water purifier and self-cleaning water purifier. The traditional water purifier is a gradual water purifier, and its internal pipeline design filter element is loose in front and tight in the back, which is composed of PP meltblown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon, which is generally composed of these 5 stages connected end to end. Retention is deposited inside the filter element and needs to be manually dismantled and cleaned at regular intervals to ensure proper machine operation.

The other type is a more advanced self-cleaning water purifier, the machine is designed with two channels, and a washing water channel is added, as the washing water of ordinary domestic water passes through the channel, the raw water side of the filter element in the machine, especially the membrane filter element, is washed to achieve the role of self-cleaning, and the water that has been flowed out of the head and tail sections of the washing faucet is used to discharge the intercepted dirt in a timely and rapid manner, the structure is designed reasonably, saving the trouble of manual dismantling and washing, and eliminating the re-pollution of the institution itself, at the same time, It also reduces energy consumption costs. The self-cleaning water purifier adopts the new principle of quality circulation, and the impurities are cleaned out at any time, and the inner core is clean to avoid secondary pollution, see the working principle below for details.

However, consumers should pay attention to identify that the self-cleaning water purifier is different from the automatic sewage water purifier, computer automatic flushing water purifier and automatic backwashing water purifier seen on the market, the former is the whole machine self-cleaning, that is to say, all the filter elements inside the machine have a certain self-cleaning function; The latter flushes only one of the cartridges and not the entire machine. In layman's terms, a self-cleaning water purifier is equivalent to installing a garbage disposer on the pipeline, and the dirt can be cleaned out at any time without staying in the machine. The traditional non-self-cleaning water purifier is equivalent to placing multiple garbage cans in the room, and the dirt is usually temporarily stored in the machine, so it needs to be drained, dismantled and cleaned regularly, and the filter element needs to be replaced frequently.

Smart water purifier.

It refers to a water purifier equipped with an LED display screen and functions such as voice function, temperature monitoring control, temperature alarm, water level control, water level monitoring and alarm.

I think that because water is safe before it is purified, it is safe even if there is no uniform standard.

No water purifier can be absolutely safe.

The drinking water we use is of a certain quality assurance, and then it is purified so it is clean.

There is no absolute thing in this world, and water purifiers can only greatly reduce harmful substances in water.

The water purifier used in the household is safe and reliable tap water before the water is purified.

The water that the water purifier evolved was safe and reliable tap water before it was purified.

Because the water is safe before it is purified.

At present, the process that can retain the beneficial elements has ultrafiltration, nanofiltration and other technologies, and it is not absolutely safe, and the process of completely removing harmful substances and retaining the beneficial elements is not yet, only the pure water function of the RO reverse osmosis technology process can purify the water very cleanly, but there is no beneficial trace elements retained.

Summary. Hello!

Innovation, differentiation and focus are the core.

For the product water purifier, (+ is the core interest level.

Hello! Innovation, differentiation and focus are the core.

I choose it among this.

Brand is the core interest of a business.

1. Products, 2. Enterprise-Consumer, 3. United States.

Please fill in the form as above.

With the rapid development of the economy, people's living standards are also improving, mineral water, pure water, natural water and other drinking water methods for consumers to choose, more choices, naturally is a good thing, but also let many consumers worry, because of all kinds of water and various sayings, how to choose has been bothering consumers, let Frankny explain it for you in detail.

As we all know, there are three main types of common water: tap water, purified water and mineral water. There are various water sources in our lives, and generally substandard water has no impact on watering flowers, laundry, and cleaning rooms in daily life.

Tap water. 1.China's current drinking water standards are not strictly implemented, and the water quality of some tap water leaves the factory is not up to standard.

2.Tap water must be disinfected for drinking, but the existing methods of disinfection are not safe enough.

3.Tap water needs to reach the end user's home, but the transmission process is complex, and the secondary pollution is serious, such as aging pipes.

4.Tap water is generally boiled and is still a threat.

Bottled water. People have recognized the incompleteness of tap water, and bottled water has become one of the new and common drinking methods, and it may also be a safe and healthy drinking method for the majority of consumer groups, but is this really the case? Franny wants to say that in fact, bottled water and tap water also have a lot of insecurity.

1.Bottled water is not healthy;

2.Bacteria breed quickly, and the secondary pollution is serious.

Bottled water is used in combination water dispensers, but once the bottled water is opened, it is easy to be polluted by the air, which will breed a large amount of organic matter, and the bottled water on the market is sterilized by ozone, ozone is a strong oxidant, which itself will make people oxygen poisoning, causing some adverse reactions, and ozone will also react with minerals in the water to produce some carcinogenic substances.

Bottled mineral water.

Perhaps compared with tap water and bottled water, everyone thinks that bottled mineral water is a more reassuring way to drink water, although it usually meets the drinking water standards stipulated by the state, but bottled mineral water also has certain drawbacks.

The existing products of bottled mineral water are mixed, and the quality control is not easy! There are many products related to mineral water on the market, but they are mixed, for example, in the access to water sources, so it is difficult to monitor the quality of mineral water. Many unscrupulous manufacturers actually use tap water as mineral water, and the source of mineral water is also extremely difficult to control.

Purify the water. Authoritative ** and water purification experts have pointed out that the best way to drink water now is to install a water purifier, which is safe and affordable!

1.Water purifiers are generally multi-stage filtration, which can efficiently filter all pollutant substances in the water and ensure the purity of the water.

2.The water purifier is installed in the user terminal, and the secondary pollution problem is very rare.

3.The water purifier is directly connected to the tap water, filtered through the tap water, with low economic cost, suitable for ordinary families, and drinking clean water is no longer the privilege of local tyrants.

In today's increasingly severe environmental pollution, if you want to drink water safely and healthily, it is recommended to install a suitable water purifier and treat the water before drinking.

1. Solve the secondary pollution of tap water.

After the tap water is disinfected with chlorine, it can kill viruses and bacteria, but cannot remove heavy metals and volatile substances. After the tap water is transported by the pipeline for a long time, it is susceptible to secondary pollution, so the tap water will basically choose to boil before drinking, but boiling can only solve the problem of bacteria, can not solve the problems of sediment, rust, heavy metals, volatile substances and bacterial corpses, and the residual chlorine in the tap water will produce chloroform after boiling at high temperature, chloroform is a standard carcinogen, so just boil, the quality of drinking water will not be fundamentally improved, and it will cause serious hidden dangers to health.

2. The best choice to replace bottled water.

A barrel of bottled water ranges from about 70 yuan, the cost is high, and most of this water is tap water processed by large water purifiers or pure water machines, and few natural wells are on the market; At the same time, bottled water has a short storage time, is easy to deteriorate, and is in an open state after being connected to a water dispenser, which will be polluted by pollutants in the air, so it is not an ideal drinking water solution.

3. The cost of bottled water is extremely high.

Bottled water is listed as daily water by a few wealthy families, but this method is too expensive and may not be as effective as a water purifier.

4. It meets the standard of raw drinking and the cost is low.

The water purifier can effectively separate and remove all kinds of pollutants, such as bacteria, residual chlorine, heavy metals, volatile substances, rust, sediment and other impurities and harmful substances in the water, and the cost is much lower than that of bottled water.

It's like air pollution, smog, and wearing a mask.

With the continuous development of economy and society, people's living standards are constantly improving, tap water has become more and more unable to meet people's daily needs for drinking water, water purifiers have begun to enter people's field of vision, and are widely used. We all know that water is the source of life, so the quality of drinking water is related to people's health, therefore, the purchase of water purifiers can not be sloppy, must be carefully selected. We all know that the purer the drinking water, the better, so how do we choose a water purifier scientifically in life?

The first point is to see whether the water purifier has a sanitary approval document. When choosing a water purifier, don't just pursue low**, but choose products approved by the Chinese Ministry of Health, check whether the approved product model matches the actual product model, and you can also check the water approval documents of the Ministry of Health through the Internet, or call the local health supervision department to verify the legitimacy and authenticity of the product brand.

The second point is to compare the strength of well-known brand water purifier companies. Because its filter element is a consumable, the water purifier needs to be replaced regularly, which requires professional and technical personnel to clean, maintain and disinfect, otherwise impurities will be deposited in the water purifier, resulting in the reduction of the function of the filter element, which is easy to breed bacteria, thus affecting health. Only large companies with a good reputation can provide high-quality water purification equipment and ensure after-sales service in the later stage.

The third point is that the more filters the water purifier is, the better. The reason why the water purifier can purify tap water is through the joint action of several internal filter elements, although the primary filtration can have a certain effect, but the material of the filter element is the most important. Therefore, the filter element must be made of good material.

Fourth, water consumption is a measure. Generally speaking, the water consumption of a household can be divided into two categories: one is domestic water for daily life, such as cleaning, washing and bathing, and the other is domestic drinking water, such as drinking, cooking rice and soup.

Different types of domestic water have different requirements for water quality, and we must choose a water purifier with corresponding purification function according to the type of water used.

First of all, we have to see whether the water purifier has a national approval document, the second is to pick a well-known brand of water purifier, and the third is that the filter material of the water purifier is very important, and it is necessary to pick a good one.

Water purifiers should give priority to choosing big brands, at least the sanitary quality is guaranteed, and secondly, it is necessary to choose the ones that are easy to clean, and the water purifiers generally need to be cleaned every two or three months.

The mineral content of water in each region is different, so it is necessary to choose a bad mineral ratio according to the needs of the human body.

There are generally two types of water purifiers. Reverse osmosis water purifier and ultrafiltration water purifier.

The most important thing for ultrafiltration water purifier is the ultrafiltration membrane, the ultrafiltration membrane of this small household machine is domestic, and the filtration effect is to remove all the impurities except for mineral ions, because the mineral ions are retained, so the scaling calcium and magnesium are not removed, which is suitable for areas with good water quality.

Reverse osmosis water purifier is mainly reverse osmosis membrane, and the effluent is pure water. In areas with poor water quality (generally poor in the north), ultrafiltration cannot achieve the desired effect, so reverse osmosis water purifiers are selected.

There are several types of reverse osmosis membranes: Dow membrane, Huitong membrane, and Shihan membrane, and Dow membrane (remember that it is Dow this Dow) is the best.

The reverse osmosis water purifier needs to be pressurized, and the difference between the pump is not very big, but the reputation of the delta is really good.

I don't understand the solenoid valve, who cares about this little thing, ......

The first choice for water purifiers is the United States and Germany, and the two of them are the fathers of water purifiers in the world Some filter elements or something are patented by them Other brands want to use this technology, and they can also charge for it, so the question of buying other brands of genuine products and costs remains to be determined.

There are two definitions of water self-purification: the broad definition refers to the polluted water body, through the physical, chemical and biological actions in the water, the pollutant concentration is reduced and restored to the level before pollution; The narrow definition refers to the process by which microorganisms in a water body oxidize and decompose organic matter so that the water body can be purified.

The self-purification of water body is mainly achieved through three aspects.

Physical Action. The physical process consists of the gradual sinking of the sedimentable solids, the dilution and mixing of suspended solids, colloids and dissolved contaminants, and the gradual reduction of concentrations. Dilution is an important physical purification process.

Chemical action. Due to oxidation, reduction, acid-base reaction, decomposition, compounding, adsorption and cohesion, the existence form of pollutants changes and the concentration decreases.

Biological effects. Pollutants are degraded due to the activities of various organisms (algae, microorganisms, etc.), especially the oxidative decomposition of organic matter in water by microorganisms. It plays a very important role in the self-purification of water bodies. Physical processes such as precipitation, dilution, and mixing of pollutants in water bodies, chemical and physicochemical processes such as redox, decomposition and compounding, adsorption and coagulation, and biochemical processes often occur at the same time, affect each other, and are intertwined with each other.

Generally speaking, physical and biochemical processes play a major role in the self-purification of water bodies.
