Water purifier knowledge, PP cotton articles

Most household water purifiers or pure water machine first-stage filter cartridges are made of PP cotton filter. The first-stage filter will not only directly affect the water quality, but also affect the subsequent three or four-stage filtration effect. The life of the filter element, so the quality of the PP cotton filter is especially important for the water purifier.
What is a PP cotton filter
PP cotton filter, also known as melt-blown PP filter, uses non-toxic and odorless polypropylene particles, which are heated, melted, spun, drawn, and shaped to form a tubular filter. If the raw material is mainly polyester fiber, it can be called PP melt-blown filter.What are the advantages of the PP cotton filter?
Let the particles in the water be invisible
When the water flows through the PP cotton filter, it enters the interior from the outer layer. The inner layer of the PP cotton filter is smaller, the smaller the aperture is, the higher the filtration precision is. Therefore, the particulate impurities will bridge when passing through the PP cotton filter channel. phenomenon. This allows those particles smaller than the pores to be intercepted by the PP cotton, and the various particulate impurities in the water are invisible, and all are filtered by the PP cotton filter.

Multi-layer gradient structure, large amount of dirt
The PP cotton filter adopts a multi-layer gradient structure: the outer layer is coarse and the inner layer is fine; the outer layer is relatively loose and the inner layer is tight. This multi-layer gradient structure allows each layer of the PP cotton filter to intercept and store impurities in the water, and the amount of dirt is naturally large.
Clean and hygienic, large filtration flow
PP polypropylene filter raw material polypropylene fiber is entangled by self-adhesive, does not require bonding of other materials, and has a clean chemical composition that meets food hygiene standards. In addition, the three-dimensional labyrinth structure of the PP cotton filter allows it to have a larger surface area and a higher porosity. The large surface area and more small holes allow the water to pass through the PP cotton quickly, and the filtration flow is increased.

Good stability, acid, alkali, organic solution, etc.
The raw material of the PP cotton filter is polypropylene. The chemical stability of polypropylene is very good. Besides being attacked by concentrated sulfuric acid and concentrated nitric acid, it is stable to various other chemical agents. Because PP cotton has good stability, it is widely used in various fields such as chemistry and electronics.

The reason why PP cotton is widely used in the pre-filter filter of water purifiers is precise because of these advantages and the low production cost. However, the PP cotton filter can only filter out large particles of impurities in the water. For heavy metal ions and microorganisms in the water, it is also required to be subjected to deep filtration treatment for the subsequent filter element.

The PP cotton filter has a uniform and dense pore size, and the highest precision of filtration can reach 1μm. It is mainly used to filter out impurities larger than 1μm in tap water. In addition, the filtration process of the PP cotton filter is because the PP cotton filter belongs to the first filter of the water purifier. More than 80% of the impurities will be filtered out at this level, and the more impurities are filtered, the easier the filter element will block. Therefore, the life of the PP cotton filter is very short. The area with poor water quality may need to be replaced after more than two months, and the area with better water quality will not exceed six months. Therefore, if you purchase a PP cotton filter inside the household water purifier, in order to avoid secondary pollution of the water purifier and affect the filter effect of the filter, it is recommended that you replace the filter every 3-6 months.

The role of the water purifier is not just to drink water!

The role of the water purifier is not just to drink water!

Many people in the modern world choose to evade many things without knowing three words, but often you don’t know but it doesn’t mean it doesn’t exist. Just like water, seemingly clean water does not mean the presence of no dirt. Even if it is not seen by the naked eye, it will still damage our body and affect the health of ourselves and our families. Especially in this fast-paced, fast-paced era, heavy industry pollution is flooding every inch of air and water we have. Although we can’t choose air, we can choose good water.

Installing a water purifier is a guarantee for the safety of household drinking water. In fact, everyone knows that the water purifier is nothing more than the end drinking system, mainly to solve the problem of drinking water in our family, but in fact the water purifier is divided into three systems, according to the needs of the family, you can use different systems, the following small series Take everyone to find out:

First, the pre-filter system

This kind of system is generally installed behind the water meter of the household water inlet pipe. The main function is to remove impurities visible in the water, such as sand and rust. It is used to protect daily household appliances from water and to prevent blockage of water pipes.

Second, the end of the direct drinking system

This system is believed to be very familiar to most people. It is to purify our daily drinking water. It is usually divided into two types: ultrafiltration and reverse osmosis. These two types have obvious differences. Ultrafiltration top 10 best water purifiers It can remove bacteria and viruses in the water, while retaining the mineral elements contained in the water, but it will not remove the scale in the water; the reverse osmosis water purifier is actually a pure water machine, which can remove all the substances in the water, including of course The mineral elements contained in the water, so for the difference between the two, Xiaobian suggested that the ultrafiltration water purifier should be installed in the south. Because the hardness of the water in the south is low, it is recommended to use the reverse osmosis water purifier in the north because of the hardness of the water in the north. Higher.

Third, the whole house water purification system

This system is actually a combination of a central household water purifier and a central water softener based on the end drinking system and the front water purification system. The central water purifier is connected to the pre-filter and is generally installed in the kitchen. It can effectively remove residual chlorine, bacteria, viruses, heavy metals, and various organic substances in the water to ensure the water is clean and sterile. The central water softener, as its name suggests, is the water purification system that softens the water. The main function is to use the resin separation technology or nanocrystalline technology to remove excess calcium and magnesium ions in the water and reduce the hardness of the water. It is generally used for bathing and washing clothes, so the cleaning will make the skin is smoother and the clothes are softer.

Do you know the role of the water purifier?

Do you know the role of the water purifier?

About the water, the purifier is now something that every household must install. The lack of water on the earth has made the quality of today’s groundwater worse and worse. If there is no water purifier at home, it seems that it is difficult to drink pure tap water. But in life, the existence of household water purifiers can really purify tap water to the point where it can be directly consumed. So what are the real rhetoric about the home water purifier? What are the mistakes?

First of all, the slogan advocated by the manufacturer said that 100% of the clarification, the water purification effect of the water purifier can really achieve the promise of the manufacturer? The answer is no, although the water purifier is called water purifier, its clean water The effect is not as exaggerated as it is said. Water purifiers often remove impurities from the slurry through adsorption and filtration devices, but when it comes to drinking directly, it is impossible to filter out all the microorganisms inside the water.

There are also some unscrupulous merchants who even claim that the water purifier is a functional water purifier that can purify the water to the point where it can cure all diseases. What the manufacturer said is the left ear and the right ear. The water purifier is blown high again. The water purifier is only a clean water object. Its pure water is through physical effects, and it can’t reach all the substances in the 100% filtered water. Staying, the magical effect of removing all the substances.

So in the end, what is the role of the water purifier? Today, explain the three main functions of the water purifier. First of all, the water purifier can remove the odor. Many times when we drink tap water, the first reaction is why we feel the rust smell in the water, the smell of sand and gravel, and even the smell of fish. It is derived from most of the pollution of groundwater, although it can reach the point of drinking, today’s groundwater has lost its proper taste compared to the previously sweet mountain spring groundwater.

The way to remove the taste of the water purifier is very physical and scientific, and one of the processes is to add it inside, but it is also easy to remove some chemicals so that the tap water can be restored after purification by the water purifier. Sweet and clear taste.

The second function of the water purifier is to remove impurities. Many people know that the water purifier is actually to let the impurities in the water be fully filtered and absorbed, giving us safer drinking water, and the specifications of these impurities are large. Everything is small. After a long period of time, the filtration system inside the water purifier also needs to be replaced regularly. But don’t think of these features too magically. It is something that can purify rust, silt, algae.

Then the last part of the water purifier is to remove the bacteria. The water purifier is the reverse osmosis principle that can remove a large part of the bacteria. It can absorb the bacteria in the water to the place where it should go, thus decomposing better and better. Good quality water, let us drink. So is there really a need to install a water purifier at home? In fact, it can be separated according to people’s living standards and quality. If you feel that you want to give your family a higher quality and healthy life, then installing a water purifier is for you. A very necessary thing. However, if the filter element cannot be replaced in time after installation, or if there is no repair and maintenance for a long time, it will nourish more bacteria, so it is necessary to properly consider this problem.

What are the water pollution?

What is water pollution?

Water pollution classification
There are two types of water pollution: one is natural pollution; the other is man-made pollution. At present, the most harmful to the water body is man-made pollution. Water pollution can be mainly divided into chemical pollution and physical pollution according to different pollution impurities. And biological pollution in three major categories.
Chemical pollution
Polluted impurities are water pollution caused by chemicals. Chemical pollution can be divided into 6 categories according to specific pollution impurities:
(1) Inorganic pollutants: The inorganic pollutants polluting water bodies are acid, alkali and some inorganic salts. Acid-base pollution changes the pH value of water bodies, hinders the self-purification of water bodies, and corrodes ships and underwater buildings, affecting Fishery.
(2) Inorganic toxic substances: inorganic toxic substances that pollute water bodies are mainly substances with potential long-term effects such as heavy metals, mainly including mercury, cadmium, lead, arsenic and other elements.
(3) Organic toxic substances: The organic toxic substances polluting water bodies are mainly various organic pesticides, polycyclic aromatic hydrocarbons, aromatic hydrocarbons, etc. Most of them are synthetic substances, which are chemically stable and difficult to be decomposed by organisms.
(4) Aerobic pollutants: organic acids such as carbohydrates, proteins, fats, phenols and alcohols contained in domestic sewage and certain industrial wastewaters can be decomposed by microorganisms. In the process of decomposition, a large amount of oxygen is required. Called aerobic pollutants.
(5) Plant nutrients: mainly plant nutrients such as nitrogen and phosphorus in domestic and industrial sewage, and residual nitrogen and phosphorus in farmland drainage.
(6) Oil-based pollutants: mainly refers to the pollution of oil to water bodies, especially marine oil production and tanker accidents.
Physical pollution
Physical pollution includes:
(1) Suspended material pollution: suspended matter refers to insoluble substances contained in water, including solid materials and foam plastics. They are wastes from domestic sewage, garbage, and mining, quarrying, construction, food processing, papermaking, etc. The suspended matter caused by water and soil loss in water or farmland affects the appearance of water, hinders the photosynthesis of plants in water, reduces the dissolution of oxygen, and is unfavorable to aquatic organisms.
(2) Thermal pollution: If the cooling water from various industrial processes is directly discharged into the water body without taking measures, it may cause the water temperature to rise, the dissolved oxygen content to decrease, and the toxicity of some toxic substances in the water to increase. Thus endangering the growth of fish and aquatic life.
(3) Radioactive pollution: Due to the development of the atomic energy industry, the exploitation of radioactive mineral deposits, the establishment of nuclear tests and nuclear power plants, and the application of isotopes in the fields of medicine, industry, and research, the radioactive wastewater, and waste are significantly increased, causing certain radioactive pollution.
Biological pollution
Domestic sewage, especially hospital sewage and some industrial wastewater polluting water, can often bring in some pathogenic microorganisms. For example, some pathogenic bacteria originally found in the intestines of humans and animals, such as typhoid fever, paratyphoid fever, cholera bacteria, etc. can pass through humans and animals. The feces are polluted and enter the water body and spread with the water. Some viruses, such as hepatitis virus and adenovirus, are also found in polluted water. Some parasitic diseases such as amoebic dysentery, schistosomiasis, leptospirosis, etc. It can also be spread by water. Preventing the contamination of water by pathogenic microorganisms is also a major issue to protect the environment and protect human health.
The source of water when the earth is formed
Source of water
The Earth is the only planet among the eight major solar systems covered by liquid water. The origin of water on the earth is very different in academics. There are dozens of different water formation theories. There are opinions that in the early days of the formation of the earth, the original Hydrogen in the atmosphere, oxidized synthetic water, and water vapor gradually condense and form oceans. It is also believed that the formation of the earth’s nebula material originally contained water. In addition, it is believed that silicates and other substances in the original crust are affected by volcanoes. Influence and reaction, precipitation of water. There are also views that the comets and meteorites attracted by the earth are the main sources of water on the earth, and even the water on the earth is still increasing.
When we open the world map, when we face the globe, most of the area presented to us is bright blue. Looking at the earth from space, the earth we live in is an elliptical, extremely beautiful azure sphere. Water is the most natural material on the surface of the earth. It covers more than 70% of the earth’s surface. The earth is veritable big water polo.
Some people may ask: Where is the water coming from? Is there water on earth?
When the earth was just born, there was no river, no ocean, no life, its surface was dry, and there was little water in the atmosphere. Now the vast sea, the endless river, the vast lakes, the strange shape The eternal years of ice and snow, as well as the underground springs and the rain and snow in the sky, where did the water come from?
The original Earth is a mixture of interstellar matter differentiated by the solar nebula. Its basic composition is hydrogen and nitrogen and some dust. Solid dust gathers to form the core of the earth, surrounded by a large amount of gas. When the earth is formed, the structure is loose. The quality is not large, the gravitation is small, and the temperature is very low. Later, as the earth continues to shrink, the radioactive material of the core generates energy, causing the earth’s temperature to rise continuously. Some substances slowly warm and melt, and heavier substances such as iron and nickel. The nucleus is formed at the center, and the lightest material floats on the surface. As the surface temperature of the earth gradually decreases, the surface begins to form a hard crust. However, due to the high temperature inside the earth, the magma activity is very intense. The volcanic eruption is very frequent. The earth’s crust is also constantly changing. In some places, ridges form peaks, and some places sink to form lowlands and valleys. At the same time, a large amount of gas is emitted. As the earth’s volume shrinks, gravity also increases. At this time, these gases are unable to get rid of the earth. The gravitational force, which surrounds the earth, constitutes the “primitive earth atmosphere.” The original atmosphere is composed of various components, and water vapor is among them. One.

What is the role of the water purifier?

What is the role of the water purifier?

The function of China’s best water purifier is to perform water treatment for deep filtration and purification treatment of water quality according to the requirements for the use of water.

The core of the technology is the filter membrane in the filter element device. At present, the main technology is derived from the ultrafiltration membrane and the RO reverse osmosis membrane.

The water purifier can effectively remove rust, sand and gravel, colloids and chemical reagents such as residual chlorine, smell, color and pesticide in the water.

It can effectively remove impurities such as bacteria, germs, toxins, and heavy metals in water.

The application of water purification technology in the field of drinking water makes the phenomenon of “unacceptable soil and water” soon become history, effectively solving the local diseases caused by excessive harmful substances in groundwater in many places.

Extended information:
The working principle of the water purifier:

First stage: Microfiltration membrane: Microfiltration membrane removes various visible objects/dust and impurities in tap water. This particulate matter comes from pipe aging, rust, secondary pollution of roof tanks, and so on.

Second stage: Compressed carbon: Compressed carbon removes chlorine and organic impurities such as harmful pesticides. It also absorbs the odors, colors, and odors of organic compounds in water, which are derived from the disinfection by-products of tap water.

Third stage: Ultrafiltration membrane: Ultrafiltration membrane can remove bacteria, viruses, and spores from water.

The fourth stage: the filter life indicator: the inside of the device is designed for the gear structure. As the water flows through, the gear rotates to move the inner one axially until the water outlet is blocked, and the water flow cannot pass, that is, through the design. The itinerary calculates the total amount of water in the water purifier to ensure that the water is safe.

What is the water purifier? What are the functions of the water purifier?

What is a water purifier? What are the functions of the water purifier?

Water is the source of life. We have to drink water every day, so the quality of drinking water is closely related to our health. The function of the water purifier is to filter out floating objects such as heavy metals, bacteria, and viruses in the water. So, what is the water purifier? What are the functions of the water purifier? Let’s take a look at the knowledge of the water purifier!
How is the water purifier good?
1, the water has no pollutants
Common pollutants are mainly bacteria, viruses, heavy metals, organic matter, inorganic substances, cyanobacteria, red worms, colloids and so on. The main function of the water purifier is to filter out these harmful substances to ensure the safety of the water.
2, effectively remove residual chlorine
The main disinfection process in the waterworks is to make chlorine into the water, which is why tap water has the taste of bleach. Residual chlorine is not pollution. The country requires that the tap water to the household must contain chlorine. However, residual chlorine will produce carcinogen chloroform in the water, and the taste of the bleaching powder will also affect the taste of the water. In addition to the general form of residual chlorine in the water, the purifier is activated carbon adsorption, then the quality and service life of the activated carbon determines the adsorption effect.
3, no secondary pollution
Whether the water filtered by the water purifier can be drunk depends on whether the water purifier itself will cause pollution, so the choice of the material and filter material of the water purifier is particularly important. For example, as mentioned above, the quality of activated carbon has been exceeded by many domestic models of water purifiers. The main reason is the use of wood charcoal and coal charcoal. The activated carbon used in the water purifier is preferably coconut shell charcoal, which is processed from the coconut shell and is more expensive. In addition, some manufacturers promote their products with the addition of medical stone, which can increase the minerals in the water. This is nonsense. Products with such substances cannot pass the national quality inspection.
What are the functions of the water purifier?
1. Remove the sediment and rust from the water.
Most of the tap water comes from rivers, and there are naturally some river sands in the water. The wide-scale filtration of the water company is impossible to completely remove the sediment. The rust is derived from the oxidation of the tap water pipe, and the filter element of the water purifier filters out 0.01 UM of impurities, which can be completely filtered out through the water purifier.
2, remove organic pollution in water
Organic pollution in tap water is very serious in industrial cities, and these organic pollutions are quite harmful to the human body. The water company does not have such large equipment to remove this organic pollution, and the activated carbon adsorption filter of the household water purifier can completely remove the organic pollution.
3. Soften tap water and remove heavy metal ions from water
There are a lot of heavy metal ions in the tap water, and the human body ingests too much heavy metal, which will bring human life to life. RO reverse osmosis household water purifier can completely remove heavy metal ions in water and reduce the hardness of the water.
4. Remove bacteria from tap water
Due to the extensive filtration effect of the water company, it is difficult to ensure the filtration effect. Therefore, before using tap water, the tap water must be filtered through secondary filtration to completely remove all the bacteria.
5, remove chlorine from tap water
Water companies usually use chlorine gas in the water for disinfection and bleaching. However, chlorine itself is a toxic gas that dissolves in water and forms a health hazard. If a household water purifier is installed, the activated carbon adsorption filter in the water purifier can remove chlorine from the tap water to eliminate health hazards.
Water is very important to health. The contents of how the water purifier is good and what functions of the water purifier are introduced are introduced here. Friends who are interested in knowing may wish to refer to it, I hope to be helpful!

The water purifier is good, you have to look at the filter material.

The water purifier is good, you have to look at the filter material.

Nowadays, everyone’s living conditions are getting better and better, and environmental pollution is getting worse. In some areas, drinking water is in a polluted area. In this case, many families began to choose to install a water purifier to filter tap water.
However, some people say that it is not safe to use a top 5 water purifier because the trace elements in the water will be filtered out. Some people say that the water purifier will also cause secondary pollution. Is this really true? To answer this question, we must first understand how water purifier works.

Now many home appliance manufacturers and various emerging manufacturers are producing water purifiers, more and more types, but the working principle is nothing more than two: ultrafiltration water purifier and reverse osmosis water purification.
Ultrafiltration refers to the purification of the solution, separation or concentration membrane through the separation technology to achieve the purification of the solution.
Therefore, the water purifier is mainly removed from some substances harmful to the human body. And qualified water purifiers use food-grade materials, which are generally pollution-free.
If your body function properly and you can guarantee a normal diet, even if you drink water filtered by a water purifier for a long time, your body will not have any problems. Conversely, drinking water after filtering harmful substances is safer for the human body.
Groundwater and lake water are the main sources of domestic water, but the two water sources need to be treated in depth with the test report data. Different process flows are provided according to different water quality. The main filter materials for filtering groundwater are RO membrane, PVC alloy ultrafiltration membrane, Manganese sand, KDF, activated carbon, chloroform, soft water resin, disc filter, mineral fossil, etc.

Manganese sand itself is a strong oxidant that can oxidize iron ions in water and has good performance of removing manganese and iron. It is an ideal product for removing iron and manganese from the water supply and drainage industry. According to the sanitary standard of drinking water in China, the iron content is ≤0.3mg/L and the manganese content is ≤0.1mg/L. Drinking iron with excessive iron content for a long time will seriously affect the health of the body.
Technical requirements for manganese sand for removal of iron and manganese:
1. The average density of the natural manganese sand filter material is generally in the range of 3.2 g/cm3 to 3.6 g/cm3. Except for those with special requirements for density in use.
2. The hydrochloric acid solubility of natural manganese sand filter should not exceed 3.5% (percentage by mass, the same below).
3. The sum of the breaking rate and the wear rate of the natural manganese sand filter should not exceed 3%.
4. Natural manganese sand filter material should be free of visible soil, shale, and foreign debris, and the mud content should not exceed 2.5%.

As an important filter material for water purification and decontamination, it plays an irreplaceable role in the scene of more and more modern water purifiers. Purified water can be drunk without harm to the body, but it is not encouraged to drink more. After all, Pure purified water also means serious environmental pollution. It is more hopeful to control the pollution of water sources and make our lives greener.

Water Purifier Filter Replacement Guide

Water Purifier Filter Replacement Guide

“I am willing to buy a water purifier, not willing to change the filter”, which is a common psychology of many water purifier users.
Is the filter too expensive? Too lazy? Afraid of trouble?

Even if the ultra-filter core is very long, it doesn’t want to change.
Even if the machine reminds you several times, I don’t want to change it.
Or just buy a cheap “cottage” filter and put it on.
But Xiao An wants to remind me, but don’t “be a big loss”~
As the “core” component of the good quality water purifier, once the filter element is blocked or the quality is not enough, it is like a problem with the “heart and lung function” of the person, which not only has a poor filtering effect but also makes the whole machine dull.
Imagine if the filter element fails, what are the dirty things and bacteria that cannot be filtered?

The filter element will not change for a long time, it may…
1, the filter effect is weakened, can not be purified

The adsorption capacity of the filter element is saturated, and the filter effect of the blocked filter element is greatly reduced. At this time, the filter element is like “a cup full of water.” Continued use will not only achieve the purification effect but will also “overflow”, resulting in lower purity. If you continue to use this impure water, it will let harmful impurities enter the body and affect your health.
2, overload work, filter grade damage

Household water purifiers are generally filtered step by step. If the filter element is blocked, impurities such as sediment and rust in the water will enter the next-stage filter element, so that the filter element that was not responsible for filtering large particle impurities bears an extra burden, thereby shortening its life. Just because of the bad habit of “changing the filter cartridge from time to time”, you need to lose two or more filter cartridges.

Analysis: The role of the water purifier and the benefits after installation

Analysis: The role of the water purifier and the benefits after installation

As a kind of living utensils, water purifiers are more and more important in real life. There are water purifiers in many places. The cost of water purifiers is not high, and the water filtered by them has reached the standard of raw drinks. It can effectively filter all kinds of pollutants and ensure the cleanliness of the water. Then, let’s introduce the role of the water purifier and the benefits of installing the water purifier.

The role of the water purifier
1. Improve tap water
Common waters harmful to the human body include: industrial wastewater, pesticide-contaminated water, heavy metal water, animal wastewater, etc.; common harmful substances in water are bacteria, viruses, E. coli, particulate impurities, residual chlorine and so on. The water purifier can purify all the above toxic water, and at the same time can remove the harmful substances contained in the above water. The mission of the top 5 household water purifier is to purify the water and improve the water source. It can be installed in the kitchen to purify the tap water (groundwater). It can effectively remove harmful substances such as viruses, impurities, residual chlorine, and heavy metals in the water, and wash vegetables, cook rice and soak the fruits with purified water. They are very healthy and beneficial.
2, instead of barrel bottled water
The cost of bottled water is extremely high, which is not suitable for daily use by the family. Bottled water is listed as daily water by most wealthy families. However, this method is too high for consumption and is not suitable for large-scale use, and the effect may not be like a water purifier. The barreled water is connected to the water dispenser, which has a high cost, short useful period and is more susceptible to secondary purification. A bucket of water is about 70 yuan, the cost is higher, and the water is tap water that is processed by a large water purifier or pure water. There are very few natural wells. A bucket of water is stored for a short period of time and is easy to change. It is in an open form after being connected with the water dispenser and will be purified by the purifying substance in the air.

Water purifier benefits
1. Tea: There is no residual chlorine, and the tea is more fragrant and purer.
2, use clean water to make hot pot: the top is not bleached, the soup color is positive, the taste is purer.
3,  mung bean soup: 30 minutes mung bean completely flowering, clear soup green water (cooked with tap water mung bean soup red, red foam on the top, and a long time).
4, cooking rice, steamed rice, noodles, stir-fry: no chlorine smell, rice is more fragrant.
5, electric kettle boiling water: no water, no cleaning.
6, clean the ophthalmic lens: reduce scratches, cleaner.
7, wash your face, wash your hands, take a shower: the skin is delicate and white, no longer greasy, save time and detergent.
8, laundry, towels: no longer yellow, hard;
9, extend the life of electrical appliances: water heaters, washing machines, electric irons, humidifiers, etc.

Is the water purifier useful? Xiaobian to tell you

Is the water purifier useful? Xiaobian to tell you

As the saying goes: People take food as the sky, food as the water, and water as the net.
To this end, many families have installed water purifiers to protect their family’s drinking water. However, some people believe that the tap water in the home is qualified by the water treatment plant. If the water purifier is installed, it is a kind of repeated investment, which is unnecessary consumption.

First of all, let’s first understand the channels through which tap water may be polluted after leaving the factory.
The first is the water pipe network. The tap water is delivered to the user after long-distance transportation through the water supply network. However, for a long-term tap water pipeline, after a long period of use, it will inevitably cause aging corrosion problems, which will have a great impact on the water quality of the tap water, causing yellowing, sediment, rust and other pollution in the water quality of the user’s home. problem.
This is followed by pollution from secondary water towers and water tanks. If the water tanks of some high-rise communities are not cleaned for a long time, a large number of pollutants will be stored. Long-term accumulation will lead to heavy pollution of tap water, and the tap water delivered to each household will not meet the standard of direct drinking.
Speaking of this, the following small series teaches you a few simple ways to identify the water quality at home.

Identify the water quality at home
1, look at the water
Fill the water with a glass with high transparency, and see if there are suspended impurities and precipitated impurities in the water against the light. If there are impurities in the water, it means that the water quality is too bad to meet the drinking standard.

2, smell the water
After picking up the water in a glass, smell it. If you can smell the bleaching powder (chlorine), it means that the residual chlorine in the tap water is excessive.

3, taste the water
Tasting the boiled water, the taste of the mouth is awkward, indicating that the hardness of the water is too high.

4, look at the kettle
Look at the commonly used kettle in the house, is there a layer of yellow scale on the inner wall? If there is a description that the hardness of the water is too high (the calcium and magnesium salts are too high).

5, the water has a sticky feeling and is greasy
If the water body is found to have a certain viscosity, the specific performance is that there is a hanging wire when the faucet is closed, the chopsticks can be drawn, and the hand feels slippery when washing hands, indicating that the water body may be contaminated by organic matter.

The quality of water in daily life can be distinguished by the above five methods. What if there is pollution? Can the best price of water purifier be solved? I believe that many people have a little knowledge of the home water purifier.

Is there any use of water purifier?
The working principle of the water purifier is to purify the water layer by various levels of filter elements (such as PP cotton, activated carbon, reverse osmosis membrane, etc.) to achieve the purpose of removing impurities.
The water purifier is useless, there is a way to judge, according to the following four steps, you can intuitively feel the role of the water purifier.
1, observe the filter
When you change the filter, you will understand how much harmful substance it has helped you with;

2, sewage treatment
When you see if the discharged sewage is as clean as tap water, you will understand whether the water purifier is useful;

3, fan sound method
Take a glass of tap water and a cup of purified water and smell if there is any residual chlorine or other odors;

4, observe the faucet
After installing the water purifier, observe whether there are any foreign objects such as sediment and rust in the faucet.

Why do you need to change the filter regularly?
The filter element of the water purifier is like the “kidney” of the human body. The water quality of the water purifier does not depend on the quality of the filter element but also depends on whether the filter element is replaced in time. If the filter element is not replaced for a long time, it will cause water blockage, not only the water will become smaller, but the filtration effect will also change. Weak, so that the water passing through the water purifier will not be well purified, and the purity will naturally decrease.

It is worth noting that due to a large number of bacterial impurities in the filter element, the tap water will be subject to secondary pollution, resulting in water that is dirtier than the original tap water. Therefore, users must develop a good habit of regularly changing the filter.
