Is the water purifier used in the end? Worth loading?

When it comes to water, many people don’t agree. I always say that there is no problem with water. People in a previous life have been drinking water like this. Why did we use a hot sale water purifier when we arrived in our generation? Then I will ask you, did they have fertilizer, herbicides, and pesticides in those days? How high is their food production? You may say that these are not the main problems. The problem is that water can still be drunk. If you can’t drink, the country should take care of it. Then I will tell you that you can drink, but you will get various diseases. You have not found these. Are there more and more cancers in rural areas? Are you getting younger? why? Because of the water and air, we drink have changed.

Two major sources of pollution
In the past 20 years of reform and opening-up, China’s economy has developed rapidly, but environmental pollution has become increasingly serious, especially drinking water pollution. According to the statistics of the national environmental department, 82% of the rivers in China are polluted to varying degrees; among the seven major river systems in China, the river section that is not suitable for drinking water sources is close to 40%; 78% of the rivers in urban waters are not suitable for drinking water sources. About 50% of urban groundwater is contaminated. At present, China’s waterworks still adopts traditional treatment processes, which cannot effectively remove trace contaminants in the dissolved state, especially organic pollutants, causing some harmful substances, including carcinogenic, teratogenic, mutagenic and other trace organic substances to remain in drinking water. in. According to the statistics of the Institute of Environmental Health Inspection of the Chinese Academy of Preventive Medicine (1997), according to China’s current standard of drinking water hygiene (the standard is only equivalent to the level of the developed countries in the 1970s), 76.1% of the population in China does not meet the hygiene standards. Water, the toxicological indicators exceeding 3% are Fe, Mn, fluoride, nitrate, sulfate and so on. Endemic diseases caused by drinking water are often reported in China. It is worth noting that in recent years, research on the poisoning of drinking water has been strengthened. More than 10,000 kinds of chemicals have been detected in water, and there are more than 100 kinds of carcinogenic and carcinogenic substances. Drinking water pollution has become a global public hazard.
According to a World Health Organization (WHO) survey, 80% of diseases worldwide and 50% of child deaths are associated with poor drinking water quality. More than 50 kinds of digestive diseases, infectious diseases, various skin diseases, diabetes, cancer, stone disease, cardiovascular disease, etc. due to poor drinking water quality; 50 million children die every year due to water pollution, 35 million people with cardiovascular disease, 70 million people suffer from stone disease, 90 million people suffer from hepatitis, and 30 million die from liver cancer and stomach cancer.
The hazards caused by water pollution mainly include the following aspects:
1) The water body is contaminated by pathogenic microorganisms, which can cause various infectious diseases such as cholera and typhoid fever.
2) Water bodies are contaminated by harmful organic substances (such as phenol, benzene, chloroform, carbon tetrachloride, pesticides, synthetic laundry detergents, etc.), causing various poisoning and diseases.
3) The water body is contaminated by heavy metals (Hg, Pb, Cu, etc.) and other inorganic poisons (chloride, arsenide, nitrite, etc.), causing various poisoning.

Purify water quality
So how do you improve water quality and improve water retention? The ways to improve water quality are generally:
1) Water source protection;
2) Water plant renovation;
3) Pipeline water supply;
4) Water purification of the pipe network terminal.
The protection of water sources or the renovation of waterworks can improve the quality of tap water to a certain extent, but it cannot solve the problem fundamentally, especially the secondary pollution of pipelines. Judging from China’s current national conditions, it is foreseeable that the renewal of equipment and technology in the waterworks and the overall renovation of the water pipe network will be difficult to achieve in 10-20 years.
Even with the use of pipelines for water supply, there are many problems in terms of project cost, design and construction, management and maintenance, water fee collection, health indicators, and safety level, and it only solves the problem of drinking water and cannot meet the full range of water consumption of households. Demand, no matter economically or in use, can not bring real benefits to consumers. On the other hand, the pipeline water supply can only be used for new construction. For a large number of existing residences, the water pollution problem cannot be solved due to the re-laying of the pipeline.
According to the International Health Organization study, the most effective way to enjoy healthy water is to install a water purifier at the end of the municipal water supply network, that is, the household water terminal, which can fundamentally solve the secondary pollution problem of the water pipeline, and through the depth of the terminal. The treatment is supplementing and perfecting the urban tap water treatment process so that the water quality of the tap water is greatly improved as a whole, which not only meets the needs of household drinking water but also satisfies the needs of household consumption, bathing, washing and the like in all aspects. From the engineering point of view, whether it is cost, construction difficulty, management and maintenance, use cost, health indicators, and safety level, the use of household terminal water purifier is the best choice to solve water pollution. Even in western developed countries where tap water can be drunk, 70% of households have installed household terminal water purifiers to avoid secondary pollution of the pipeline network.

The working principle and treatment of water purifier

Posted on by

The working principle and treatment of water purifier

working principle
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 household water purifier to ensure that the water is safe.

Most of the water purifiers adopt the progressive structure of the screen filter principle. The multi-stage filter elements are connected in series, and the precision of the filter elements is arranged from low to high in order to realize the multi-stage filter element to share and retain dirt, thereby reducing the filter plugging. And the number of manual sewage, wash and wash, and the period of replacement of the filter. Another new design idea is to apply the self-cleaning structure of the principle of mass distribution. Its design idea is no longer to provide as much space as possible for contaminant pollution, but to adopt a principle of separation to separate a small part of the clean water, at the same time, as far as possible, let the raw water flow as usual, so that the dirt is taken away with the water flow in time, so that the water does not rot. In this way, both purified water is obtained, and it is not easy or difficult to precipitate dirt in the machine, avoiding secondary pollution and greatly reducing filter loss, and the water quality is better, safer, and energy-saving than low carbon. This new principle of self-cleaning water purifier won the gold medal of the 7th International Invention Exhibition, which is a one-in and two-out structure. It improves the concentration of raw water impurities in the machine due to the structural defects of the traditional water purifier. The higher the accumulation, the more the sewage becomes, and therefore the self-cleaning water purifier has no concept of sewage and sewage water purifiers instead of washing water. With the improvement of living standards, the popularity of water purifiers will become wider and wider, and new technology products are better meeting people’s needs.

According to the water quality treatment method, the water purifier can be divided into the following 10 categories:

1. Softening method

It refers to removing or reducing the hardness of water (mainly calcium and magnesium ions in water) to a certain extent. During the softening process, water only softens the water and does not improve water quality.

2. Distillation

It refers to boiling water and collecting the steam to cool and condense into a liquid. Distilled water is extremely safe drinking water, but there are some issues to be further explored. Since distilled water does not contain minerals, this has become a reason for opponents to suggest that people’s life expectancy is aging. In addition, the distillation method is costly and consumes energy, and cannot remove volatile substances in water.

3. Boiling method

It refers to the drinking of tap water after boiling. This is an ancient method that is widely used in China. Boiling water kills bacteria, but some chemicals and heavy metals cannot be removed, even if their content is extremely low, so drinking is not safe.

4. Magnetization

It refers to the treatment of water by the effect of a magnetic field, called magnetization of water. The process of magnetization is the process in which the magnetization process is completed after the water passes through the magnet in a direction perpendicular to the magnetic lines of force. China’s magnetization of water is still in the initial stage of practice and research. Foreign water purifiers do not have the requirement of magnetization function, because magnetized water is not in the scope of clean water, but is a medical problem.

5. Mineralization

It refers to the addition of mineral elements (such as calcium, zinc, barium, etc.) that are beneficial to the human body on the basis of purification. Commercially available water purifiers generally achieve mineralization by adding moissanite to the water purifier, but the Ministry of Health has clearly stated that “the wading products must not promote any health care function”.

6. Ozone, ultraviolet sterilization

These aspects can only be sterilized, remove heavy metals and chemicals that do not fall into the water, and the killed bacteria remains in the water and become pyrogens.

Water purifier principle

Posted on by

Water purifier principle

The water purifier works in a variety of ways: single-machine filtration, two-stage filtration, three-stage filtration, four-stage filtration, five-level, and five-level filtration.

1. Single-stage filtration: use 1μm or 5μm PP cotton fiber filter + UDF coconut shell granular activated carbon filter to remove more than 5μm float and particulate matter in water. Clearwater source and activated carbon adsorption can effectively absorb water and odor in water. The residual chlorine improves the taste of the water. Only suitable for high-quality drinking water sources.

2, two-stage filtration: use 1μm or 5μm PP cotton polypropylene fiber filter to remove more than 5μm float and particulate matter in water to clarify the water source;

3, three-stage filtration: use 5μm PPF polypropylene fiber filter to remove more than 5μm float and particulate matter in water to clarify the water source.

4, four-stage filtration: 0.5μm CF whole diatom microporous ceramic filter can remove rust, red worm and float and particle materials in water more than 0.5μm, clarify the water source;

5. Five-level and above-level filtering: With the development of technology, the highest level of filtering is 10 or higher.

Recommended use of water purifier

Recommended use of water purifier

As for the water purifier, it should have a history of more than ten years. As the Wanfeng brand, why has there been a product of water purifiers, but it has never been widely promoted to the market? This is due to various factors. of.
People who have worked in chemical production or have studied chemistry carefully know that the surface of carbon particles has the function of adsorbing particles. Then the real principle of the water purifier is here. Many groups in the society boast magical water purifiers, and then they are desperately premium or participate in cheap gifts to entice consumers, a water purifier sells sky-high prices. As a brand development strategy, we absolutely cannot do such a thing.
The water quality after the five-pole filtration of the water purifier is indeed very good and is the standard for achieving pure water. However, according to China’s national conditions, long-term drinking of pure water will greatly reduce the individual’s immunity, and there is no real help for health. Moreover, every ton of tap water can only produce one ton of purified water, and two tons are waste water, causing a large loss of water resources.
If fake or inferior goods appear in the market or go through the streets, the products that are promoted by the assembly will probably be unqualified products, especially the quality of plastics, which may cause harm to the body.
Water purifier products, because there are multi-channel sales links, there are also problems of overcapacity, the product design of each factory, business is not the same, the quality of after-sales accessories and accessories are a series of problems.
Collecting the above factors, the Wanfeng brand’s water purifier has been in an obscure state.
We believe that a house must be used for clean water in the true sense. After many years of improved testing of German technology, the following recommendations are recommended:
1. Use the method of entering the household water, only need to wash the filter element frequently, no need to replace the filter element, which greatly helps to extend the service life of household water heaters, faucets, triangle valves and showers. (The following figure)

2. Use the ultimate version of the Wanfeng water purifier (below)

Advantages comparison: 1. No motherboard controller. 2. No power requirements. 3. No pumping booster equipment. 4. No pressurized barrel. 5, ultimately will not produce any after-sales service needs. 6. The purified water quality meets the national standard for mineral water, and healthy particles are not lacking. 7, no waste water, will not cause the loss of water resources. 8. Installation and use of the original metal pipe will not cause secondary pollution to the water quality. 9. The water flow pressure is clear at a glance. 10, the amount of water is more than five times that of ordinary water purifiers.
In summary, a rational choice of water purification equipment can really help healthy drinking water.

Is there any use of the water purifier? Four steps to understand the truth

Posted on by

Is there any use of the water purifier? Four steps to understand the truth

The brands and types of water purifiers on the market are so dazzling that consumers are not only questioning: Are these water purifiers really useful? What does it purify?

Let’s take a look at the details below with Xiaobian. Even if the water source is pure water, from the water source to the household faucet, and not to mention the pollution of tall buildings and underground reservoirs, there are several kinds of pollution that are inevitable:

First, rust
The water is transported by a galvanized iron pipe, and water and iron are oxidized to form red iron oxide, which further oxidizes to form black ferric oxide. Pipes in new buildings are more susceptible to oxidation. Almost everyone has this experience. The faucet is turned on for the first time every morning, and the red material in the effluent is rust.

Iron is an essential element of the human body, but as one of the indicators of drinking water, the iron content per liter of water must not exceed 0.3 mg.
If the naked eye can distinguish the color of rust in the water or can taste the taste of rust, then the iron content in the water is greatly exceeded, the iron content exceeds the standard, not only the perception, poor taste, long-term drinking, will increase the burden on the kidney, leading to the endocrine system disorders, high blood pressure and other diseases.
Second, lead and other heavy metals
During the transportation process, there will be a lot of heavy metals such as lead dissolved in the water. Long-term drinking will increase the burden on the liver and kidneys of the human body, and easily cause diseases in the liver, kidney, heart, and nervous system.

Third, chlorine
Chlorine is a strong oxidizing agent with a pungent odor and a mouthfeel. Chlorine is a tap water disinfectant widely used internationally.
The residual chlorine is chlorinated and disinfected. After a certain period of contact, the amount of chlorine remaining in the water. According to international requirements, the safety of residual chlorine is the end of the pipe network (at the household tap) should be kept at 0.05 mg/liter of water to control the growth of bacteria in the transportation process, so the city supply tap water contains residual chlorine.

Fourth, bacteria
Whether it is surface water or groundwater as a source of water, bacteria and E. coli in tap water can be said to be ubiquitous. Water is the source of life. The water contains nutrients, and the water has relative thermal stability, thus providing an excellent environment for the growth and reproduction of various bacteria.

Is water purifier useful?
A water purifier is a product that removes suspended solids from water and organic compounds, inorganic compounds, heavy metals, bacteria that are harmful to the human body, and retains the vector elements and minerals required by the human body. The water treated by the water purifier, although apparently no different from the original water, has undergone significant changes in water quality.

The working principle of the water purifier is to purify the water layer by various filter elements to achieve the purpose of removing impurities. The filter element of the water purifier mainly includes a granular activated carbon filter element, a reverse osmosis filter element and a rear activated carbon filter.

The filter element with good material can remove impurities such as sediment, rust, bacteria and suspended solids in the water, remove the odor in the water, and remove metal ions and radioactive substances such as calcium and magnesium in the water to completely purify and soften the water.

Do you need a water purifier? Yes, you need it!

Posted on by

Do you need a water purifier? Yes, you need it!

At the end of summer and autumn, people’s drinking water will increase greatly.
Microorganisms are more susceptible to reproduction during hot seasons.
The safety of drinking water is also particularly prominent.
Some people pick up a cup of water directly,
Some people take water from the faucet and then boil it with a kettle.
But are these waters really safe and clean?
It’s really Too Young Too Naive.
It can only be said that the ideal is full, but the reality is very skinny.
01
– The truth about water pollution –
After the bottled water is opened, it will take too long to be placed.
The water dispenser is not regularly cleaned and disinfected.
These are all likely to cause new pollution to water quality.
Even the water coming out of the tap in the house,
There is no guarantee that it will be innocent.
They pass through water plants, reservoirs, valve faucets, etc.
After a long pipeline,
Can come to your home.
This process may be
Infiltrating rust, mud, microorganisms, etc.
Affect your water quality.
02
– How much water people need per day –
research shows,
People are already in a state of micro-dehydration when they are thirsty.
Active hydration is very important.
An adult drinking every day
At least 1500-1700 ml of high quality
Drinking water (about 7-8 cups).
——Source: “Chinese Dietary Guidelines (2016)”
03
– The taste of water can also be optimized –
Tap water may contain
Residual chlorine, volatile organic compounds, disinfection by-products, etc.
Affect the smell and taste of drinking water.

The trend of the water purifier is not going to buy!

The trend of the water purifier is not going to buy!

As the saying goes: People take food as the sky, food as the water, and water as the net. However, in daily life, we cannot fully understand whether the fruits and vegetables we eat every day are green foods, nor can we decide whether the air will be fresh tomorrow?
The only thing that controls is the water that goes into the body every bite.
Because water is the “source of life”
Why use a water purifier?
On earth, where there is water, there is life. Life originates from water, what kind of water is healthy, and more and more people are drinking less tap water, and they are becoming less and less practical. They are also increasingly aware that drinking water is a serious science. problem.
In fact, after the tap water is boiled, there is still no way to remove dirt, heavy metals, volatile substances and bacterial carcasses in the water. Even if it is disinfected by chlorine, these problems will still exist, and after chlorine gas is used, residual chlorine will be present in the water.
Therefore, boiling water can only eliminate some bacteria, and there is no way to deal with sediment, rust, heavy metals and so on. A water purifier will be needed to further address these issues.
What are the benefits of using a water purifier?
For the family, installing a household water purifier can be said to have a small water plant at home.
Not only is the purity of the water high, but it is also very convenient, so that people can drink healthy high-quality water at any time, and it is safer than bottled water and bottled water, and can save a lot of money for the family.
1. Cleaner than boiled water
Although the boiled water is boiled, some bacteria have died, but the alum, sediment, rust, high-temperature bacteria, chlorine, heavy metals and other harmful substances in the water cannot be removed even if they are boiled.
2. Save peace of mind, save money, save money
Many people use bottled water instead of tap water, but the bottled water on the market is mixed and the quality is worrying. In addition, the bottled water must be consumed within a certain period of time. Exceeding the time limit, bacterial microbes are abundantly produced and endanger human health.
3. More effective removal of harmful substances
The working principle of the water purifier is to purify the water layer by various filter elements (such as PP cotton, activated carbon, reverse osmosis membrane, ozone sterilization, etc.) to achieve the purpose of removing impurities.
The tap water passes through the PP cotton filter element, the granular activated carbon filter element, the sintered activated carbon filter element, the reverse osmosis filter element and the silver-loaded activated carbon filter element at one time to remove other substances such as sediment, rust, colloid, bacteria, suspended matter and the like in the water.
The biggest use of the water purifier is to purify the tap water. The water purifier filters the suspended solids, bacteria, rust, algae, microorganisms and other impurities in the tap water through the adsorption of activated carbon and other filter elements, so that the drinking water of daily life becomes pure; The filter can also filter out the residual chlorine in the tap water, and the filtered water is more healthy.
4. Don’t worry about your child drinking safely
Drinking habits can make children smarter. Experts survey found that some parents in the pregnancy, pregnancy, because the drinking water is not healthy, resulting in poor baby development, poor health after birth.
It can be seen that the purity of drinking water is directly related to the health of children. The younger the child, the higher the proportion of water needed in the body, and the greater the impact of drinking water quality on the child.
