How to get healthy drinking water

With the continuous improvement of living standards, people pay more and more attention to healthy drinking water, but there are still many doubts about how to obtain healthy drinking water. Recently, kaineng environmental protection (Stock Code: 300272) will publicize relevant issues in the name of "doctor of water". Today, the first thing to discuss is the characteristics of KDF copper zinc alloy filter material and its role in water treatment.

High zinc content in purified water means more harmful substances are replaced

Kaineng environmental protection most water purifiers are equipped with KDF copper zinc alloy filter material imported from the United States and high-quality coconut shell activated carbon. As a safe and effective water purification filter material, KDF has been widely recognized in the world. It has been certified by the National Health Foundation (NSF) of the United States, and is defined as "microbial inhibition device" by the environmental protection agency of the United States. In China, KDF has also obtained the health safety inspection report from the national health department.

KDF can exchange electron with residual chlorine and heavy metals in water. If the content of this kind of substance in water is higher, more zinc ions will be exchanged. These principles can be seen by searching "KDF" in Baidu Library, such as "the zinc released from KDF treatment medium has obvious control effect on microorganisms, and zinc can prevent the synthesis of enzymes, thus affecting the normal growth of organisms and inhibiting the reproduction of microorganisms".

Why does the zinc in purified water exceed the standard? There are many reasons for this phenomenon. For example, due to the special water quality of Huangpu River in some areas of Shanghai in the previous period, waterworks increased the dosage of chlorine in water to ensure thorough disinfection and sterilization. In addition, due to the old local water pipelines, the residues of chlorine and heavy metals in water increased. In this regard, kaineng sales and service personnel will specifically recommend the water purifier with KDF filter material, but KDF will increase the zinc content in the effluent in order to deal with these harmful substances. This is a normal phenomenon in the period of poor water quality. The increase of zinc content in water, in turn, also shows that it eliminates more harmful substances, indicating that the performance of water purifier is excellent.

Zinc content in drinking water is an index of sensory properties, and zinc is beneficial to human body

What does excessive zinc mean? According to the hygienic standard for drinking water in China, the zinc content in drinking water should not be more than 1mg / L, but it is a "sensory and general chemical index". When the zinc content is high, milky white phenomenon is easy to appear in the water, which is not acceptable to some residents. However, zinc content is not a toxicological index. Horizontally, there is no zinc content index in WHO drinking water standards. According to the American drinking water quality standard, the limit of zinc content is no more than 5mg / L, which is a recommended sensory index. Many health products and nutritious products can also show that zinc is beneficial to human body. For example, the manual of "Sanjing brand zinc gluconate oral liquid" states that every 100ml oral liquid contains 35.3mg zinc. The content of zinc in children's formula milk powder and milk with zinc is much higher than 1 mg / L.

Copper zinc alloy was first developed and utilized as an effective water treatment material in the United States. In fact, it has a long history in China. Brass is the alloy material of copper and zinc. In ancient China, brass was used as a vessel to hold water and food. Most of the faucets in modern life are made of brass. When heavy metal pollution occurs, zinc will overflow into water and food, but it is beneficial and harmless to human body.

Kaineng environmental protection has and will continue to make a responsible commitment: our water purifier is connected to normal tap water, and we will be fully responsible for any direct health damage caused by the increase of zinc content in the effluent.

Scientific and rational view of safety and health standards

At present, people pay more and more attention to water and food safety, but many people are not clear about the requirement of "health" besides "safety". Generally speaking, the government is in charge of safety and the family is in charge of health. But health and safety are different, sometimes even contradictory. For example, the waterworks will add chlorine in the water to avoid the growth of bacteria and viruses in the water during transportation, which is for safety reasons; but from the perspective of health, after the tap water enters the household, it is better to remove the residual chlorine before the residents use it, because chlorine is harmful to the human body. The book "safe drinking water and scientific drinking water" written by Fu Jiamo, academician of the Chinese Academy of Sciences, and edited by Professor Cai Zugen clarifies that "at present, chlorine containing disinfectants are the mainstream disinfection methods in domestic water body disinfection", "its disadvantage is that it can remove bacteria and also produce some disinfection by-products, including trihalomethanes, haloacetic acids Haloacetic acids and trihalomethanes are "carcinogenic, teratogenic and mutagenic" substances, which pose a potential threat to human health

The chlorine in the water purified by the water purifier is removed. This kind of water is of course healthy and good for drinking. However, according to the sanitary standard for drinking water, the chlorine content of tap water in residents' homes should not be lower than 0.05mg/l, and the water without chlorine is not up to the standard. But for users, it's healthy drinking water.

Kaineng environmental protection products advocate natural methods to remove harmful substances in water and retain beneficial substances, so as to get healthy drinking water. The treatment object of kaineng domestic water purifier is municipal tap water. Kaineng's products will further improve the quality of drinking water. According to the product design, under the condition that the tap water is basically normal (the residual chlorine and heavy metal content in the water is normal), this water purifier can effectively remove heavy metals and residual chlorine, and the zinc content in the water will be within the standard. However, when the quality of tap water fluctuates, especially when the residual chlorine and heavy metals seriously exceed the standard, it is easy to have a higher zinc content, which is a harmless and healthy phenomenon.

To sum up, the copper zinc alloy filter material represented by KDF is a unique filter material in today's water treatment industry, which can not only eliminate residual chlorine and heavy metals in water, but also retain beneficial substances. Of course, any kind of water treatment process is not perfect, but it can be improved by the engineers of kaineng through technical means.

Kaineng environmental protection as an industrial tourist spot, welcome all walks of life to visit and experience

As a listed company in the domestic water treatment equipment industry, kaineng environmental protection has long been committed to developing and manufacturing water purifiers / softeners for the whole house, terminal water purifiers and commercial drinking water purifiers that adopt different technical solutions and meet different water quality requirements of customers.
