How much do you know about harmful substances in water? Top 10 brands of water purifiers

There are three main categories of hazardous substances in water.

1. Heavy metals: including rust, sediment, lead, mercury, zinc, chromium, etc., often drinking water with excessive heavy metals is easy to cause human bone pain, dementia, stones and other diseases;

2. Pathogenic microorganisms: Drinking water with excessive bacteria is very easy to cause cholera, hepatitis A, cold, SARS, avian influenza, infectious diseases, etc.;

3. Organic chemicals: Organic chemicals such as residual chlorine in chemical fertilizers, pesticides, and tap water are very likely to cause human cell mutations, tumors, malformations and other diseases.

What are the hazards of organic matter to water bodies?

The organic matter in the water has a common characteristic, that is, it is necessary to carry out biological oxidative decomposition, which needs to consume the dissolved oxygen in the water, resulting in a lack of oxygen in the water. At the same time, spoilage fermentation occurs, causing bacteria to grow and water quality to deteriorate. Organic pollution from industrial wastewater can also reduce the quality of products.

What are Total Solids, Dissolved Solids, and Suspended Solids in Water?

All impurities in water except dissolved gases are called solids, and solids in water are divided into dissolved solids and suspended solids, and the sum of these two is called the total solids of water. Dissolved solids refer to various inorganic salts and organic matter that are still dissolved in water after water has been filtered. Suspended solids refer to those less suspended substances such as sediment, clay, organic matter, and microorganisms that are insoluble in water.

What is the salinity of water?

The various salts in water are generally in ionic form, so the salt content is the sum of the various cations and anions in the water.

The salt content in water is different from dissolved solids because dissolved solids include organic matter in addition to dissolved salts in water.

What is the hardness of water?

There are some metal cations in the water, the same metal cation is combined, in the heating process of the water, due to the evaporation and concentration, the formation of scale on the surface layer affects the conduction, the total concentration of these metal cations is called the hardness of water. Generally, the metal cations contained in water are mostly calcium, magnesium, manganese and potassium, if its concentration is more than 100ppm, it is called hard water, and when it is less than 50ppm, it is called soft water, and hard water also has the difference between permanent hard water and temporary hard water. Hard water often causes great damage to boilers and has a great impact on human health.

The main harmful substances are metals, chlorine, chlorides, water alkali is not large, you can choose a water purifier, 3M, Aihuipu targeted filtration filter element, filter out impurities more comprehensively. Other precautions can be found in Q I.

Water purifiers with RO (reverse osmosis) principle can achieve the effect you want. This is an industrialized process, which has been simply applied to life by the Chinese.

There are big differences in all kinds of products on the market, but the core components are monopolized by a few companies, so there is not much difference in the effluent quality of various brands of products, so don't think that 3000 yuan is better than 1500.

It is worth noting that the "microfiltration" filter element and the "activated carbon" filter element must be replaced regularly when the weather is hot, and the cycle should be shorter than in winter, otherwise, it is easy to form secondary pollution and microbial multiplication. If the filter element is not changed for a long time, the water that comes out is more terrible than the microorganisms of tap water, and then contaminates the subsequent RO membrane, and the water purifier will become a burden.

The RO process is as follows:

Tap water (or other raw water) – microfiltration——— activated carbon – reverse osmosis (RO) membranes——。

Some will add ultraviolet or ozone disinfection behind RO, which plays a role in the control and killing of microorganisms. It is recommended to pay attention when purchasing.

In addition: the water purifier can not completely replace drinking water, simply drinking clean water, easy to cause the loss of trace elements and minerals in the body, especially the elderly and children, try not to let them drink clean water, including pure water, mineral water, mineral water on the market.

Life Hacks:

Once the tap water is boiling, boil for a few more minutes, then remove the lid and let it dry for a few minutes before using.

Because the water is heated in the process, the disinfectant in the tap water will be heated, and a chemical reaction will occur, producing halides, which are carcinogens.

Manually hand-beaten, you don't give points and you're decadent, hehehe.

The water purifier is to filter out the ordinary impurities in the water, but there is no way to filter heavy metal ions. To remove these substances, they must be removed through processes such as ion exchange resins or reverse osmosis membranes.

If someone says that the ultrafiltration machine (UF machine) can be removed, it is fooling you, whether to remove it or not, you must look at the filtration accuracy, one ten-thousandth pore size filtration RO membrane, and one-thousandth of the ultrafiltration membrane, do you think the accuracy is better? What I am doing now is the product of Cixi Shuimiao water purifier, which is mainly based on pure water machine, and the ultrafiltration machine has a peculiar smell in the water in summer, so it will kill people. I hope I can give you something to gain.

At present, the market is mixed, look at it yourself, or buy practical and economic products for home use: you can choose to advertise less, domestic brand-name products.

If you want to be luxurious and have face: choose one with more advertising.

The basic filtration performance is okay with various famous brands in the domestic market. A little advice, think for yourself.

Beautiful! That's what we use.

The direct drinking water purifiers produced by companies on the market with the "Approval Document for Sanitary and Safe Products Involving Drinking Water in China" can filter out most of the heavy metals, which fully meets or even exceeds the direct drinking water standards formulated by the Ministry of Health of China, and can be drunk with confidence. For example, the ultrafiltration membrane direct drinking water machine is pure physical filtration, the filtration pore size of the ultrafiltration membrane is generally about microns (the size of the general bacteria is about microns), and the ultrafiltration membrane filtration pore size used in the Colvis water purifier is microns, as long as the impurities and bacteria are filtered out, and then the chlorine and heavy metals are filtered with sintered activated carbon or antioxidant ceramic filter element, and the trace elements (minerals) required for the benefit of the human body in the water are retained.

There is also a RO reverse osmosis water dispenser on the market, which is to be added by electricity, and the water that comes out is pure water, and the TDS (calcium and magnesium ion content in the water) value is generally within 10ppm. The lower the TDS value, the purer it is, because it no longer contains minerals and trace elements in water.

Water purifiers are different from other electrical appliances, the product is important, but after-sales service is more important. Because she has to change the filter cartridge regularly. Therefore, you not only have to enjoy the manufacturer's free installation service, but more importantly, you can have the manufacturer's regular after-sales tracking service, such as a reminder one month before replacing the filter element and free door-to-door replacement of the filter element.

Therefore, when you buy a water purifier, you should not only consider the product, but also the manufacturer. It's best to have a company with multiple stores or service points in your local area, and of course the manufacturer or marketing center is better in the local area.

Only in this way can after-sales service be guaranteed and timely.

OK. We all know that masks should be worn for epidemic prevention and epidemic virus, and qualified disposable masks are composed of three layers, the outer layer of non-woven fabric, the middle layer of meltblown non-woven fabric, and the inner layer of spunbond non-woven fabric, of which the melt-blown cloth is produced by PP cotton, which shows that the material used in the PP cotton filter element and the mask in the water purifier is the same, and it is not an exaggeration to say that the water purifier can filter out the coronavirus in the water.

And according to the "National Science and Technology Resource Service System for Novel Coronavirus" released by the Institute of Virus Prevention and Control of the Chinese Center for Disease Control and Prevention on January 24, 2020, the new virus is about 100 nanometers, and the filtration accuracy of reverse osmosis water purifiers is about nanometers, so reverse osmosis water purifiers can effectively filter out viruses and disinfection by-products in water.

Just like the Hanston reverse osmosis water purifier, the use of independently developed reverse osmosis membrane, the filtration accuracy has reached microns, and the average diameter of the new coronavirus is microns, which can easily intercept and remove the new crown virus in the water, and Hanston's excellent purification technology and high-quality raw materials can remove bacteria and viruses can reach more than 90%, ensuring double drinking water and water safety.

At present, the water purifier brands that have done well in reverse osmosis water purifiers include Hanston, Dorrance, Omet, Midea, etc., all of which are brands with good reputation.

Yes, if consumers install water purifiers for the purpose of improving the quality of drinking water and obtaining healthy and safe water, 80% of the reverse osmosis water purifiers on the market are qualified.

The types of harmful substances removed by the water purifier are as follows:

Removal of heavy metals: A water purifier brand that has truly passed the heavy metal removal test standard of the Center for Disease Control and Prevention under the Ministry of Health of China, and can remove heavy metals such as lead and cadmium without electricity. There is no need to worry about the threat of industrial contamination to drinking water.

Removal of rust Bleaching powder Organic pollutants: It can remove the rust remaining in the water Bleaching powder (residual chlorine) organic pollutants bring natural taste and odorless drinking water, so that children prefer to drink water and grow up healthily.

Retention of beneficial substances: While removing harmful substances, it can also retain the beneficial minerals required by the human body in drinking water, so as to meet the needs of people with different physiques for healthy drinking water, which is safe and healthier.

A reliable water purifier is able to remove harmful substances from the water. Of course, it takes a lot of technology to solve it, and membrane separation technology is the right direction, but to solve chemical pollution, activated carbon is also needed.

As the name suggests, water purifiers are used to remove harmful substances from water. However, there are too many water purifiers on the market at present, including ultrafiltration direct drinking machines, reverse osmosis water purifiers, etc., of course, there are genuine and shoddy ones.

The water purifier has more than 100 patents, and the water purification effect has been achieved, and it has obtained international NSF certification to effectively filter out heavy metals, residual chlorine and other harmful substances in the water.

Water purifier, also known as water purifier and water filter, is a water treatment equipment that deeply filters and purifies water quality according to the requirements for water use.

The water purifier that is usually talked about generally refers to a small filter used for household 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, impurities, toxins, heavy metals, etc. 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 minerals in groundwater in many places.
