Use household water purifiers to get healthy water

In recent years, the situation of water pollution has become more and more serious. However, in the area of ​​drinking water, people are still directly brushing, cooking, and rinsing milk with tap water containing rust and dissolved substances. Long-term drinking of such unhealthy water can lead to constitutional problems. Poor, the resistance weakens naturally, and there are more and more people who gradually suffer from kidney failure, cardiovascular and cerebrovascular diseases, leukemia, cancer, and heavy metal poisoning. As people's pursuit of healthy life and water quality requirements become higher and higher, as well as the maturity of domestic household water purification technology, household water purifiers will be more widely used in the daily life of ordinary families.

First, the role

Home water purifiers are small water treatment equipment. The structure of domestic water purifiers is roughly divided into several types, such as coarse filtration, activated carbon adsorption, ion exchange resin, hollow fiber, reverse osmosis membrane, and gold filter. It can effectively remove chlorine, heavy metals, bacteria, viruses, algae and suspended solids in the water. Post-activated carbon will further remove all kinds of organics, making the treated water clear, clean and sterile. Domestic water purifier can not only remove residual chlorine and odor from the water, but also remove compounds that are heavier than carcinogens. It can also remove harmful substances while retaining trace elements and beneficial minerals in water and restore natural mineral water. The tap water soup processed by the kitchen water purifier is more nutritious and delicious, and the cooking tastes more delicious. In addition, the purified water has enhanced dissolving power, and when cleaning fruits and vegetables, the surface stains and pesticide residues can be more fully removed.

Second, the working principle

1, activated carbon

More commonly used, multi-purpose nature, coal, shell (nuclear) and other carbon-containing substances are made by chemical or physical activation methods. It has a very large number of micropores and specific surface area, and therefore has a strong adsorption capacity, can effectively adsorb organic pollutants in water. The formation of some oxygen-containing functional groups on the amorphous surface of the activated carbon can make the activated carbon have chemical adsorption, catalytic oxidation, and reduction performance, and can effectively remove some of the metal ions in the water.

2, reverse osmosis

One of the separation techniques that uses pressure to move water through a synthetic membrane. The membrane allows only pure water to pass through and contaminants are removed.

3、Compound type

When a process is difficult to remove harmful substances in water, the use of two or more processes is compounded. Such as activated carbon adsorption, ultraviolet sterilization, activated carbon adsorption, reverse osmosis, activated carbon adsorption, microfiltration (ultrafiltration), polypropylene microfibers, activated carbon, microfiltration (ultrafiltration) and so on. In the compound type water purifier, the membrane technology has a good performance in the purification of the water purifier, especially in the removal of microorganisms (bacteria, algae, etc.), and some of the excellent water purifiers can directly drink raw water. Has been welcomed by the majority of consumers, has become a hot spot for the development of water purifiers.

Second, the selection technique

1, Health Permit Approval Document

Users must understand the importance of product quality when purchasing water purifiers. Manufacturers of water purifiers must obtain the sanitation license of the higher health supervision department, and pass the appraisal of the technical supervision department, which conforms to the national “Drinking Water Quality Standard”.

2, suitable filter important

The first-generation water purifiers are mainly filtered through simple activated carbon, ceramics, etc., which are easy to breed bacteria, pollute water sources, and do not reach the effect of clean water sources; second-generation water purifiers use various artificial polymer membranes to filter and are harmful to water removal. The effect is significant, but its fatal flaw is to filter out trace elements that are beneficial to the body. The third-generation water purifier adopts nano-crystal filter technology, which solves the defects of the second-generation water purifier and filters out harmful substances and heavy metals in the water. So when everyone chooses a water purifier, be sure to ask about the filter technology and filter materials used to see if they can meet their own needs.

3, safe and effective sterilization

The water purification equipment adopts two methods of sterilization, one is to add disinfectant, the disinfectant can kill a part of bacteria, but the disinfectant contains a trace of chemical components harmful to human health; the second is ultraviolet sterilization, ultraviolet sterilization technology is internationally recognized as the most effective One of the sterilization technologies, because the UV sterilization is safe and efficient, it can quickly kill almost all bacteria; and UV sterilization uses physical principles to sterilize, without any chemical agent, and will not have side effects on the human body.
