How to get healthy drinking water

With the continuous improvement of living standards, people are paying more and more attention to healthy drinking water, but there will be many doubts about how to obtain healthy drinking water. In the near future, Kaineng Environmental Protection (stock code: 300272) will publicize and popularize related issues in the name of "Dr. Water", and today we will first discuss the characteristics of KDF copper-zinc alloy filter media and its role in water treatment.

High zinc levels in clean water mean more harmful substances are displaced

Most of the water purifiers are equipped with KDF copper-zinc alloy filter material imported from the United States and high-quality coconut shell activated carbon. KDF has been widely recognized worldwide as a safe and effective water purification filter material, and has passed the National Sanitation Foundation (NSF) certification and is defined as a "microbial suppression device" by the US Environmental Protection Agency. In China, KDF has also obtained a health and safety inspection report from the national health department.

KDF can exchange electrons with residual chlorine and heavy metals in water, and if the water is high, more zinc ions will be exchanged. These principles can be seen through Baidu library search "KDF", such as "zinc released in KDF treatment medium has a significant control effect on microorganisms, zinc can prevent enzyme synthesis, thereby affecting the normal growth of organisms, to achieve the purpose of inhibiting microbial reproduction".

Why does the purified water exceed the zinc standard? There are many reasons for this phenomenon. For example, in some parts of Shanghai, due to the special situation of water quality of the Huangpu River in the previous period, the water plant increased the amount of chlorine in the water to ensure disinfection and sterilization, coupled with the outdated regional water pipelines, etc., the residue of chlorine and heavy metals in the water increased. In this regard, Kaineng sales and service staff will recommend water purifiers equipped with KDF filter material, but KDF causes the zinc content of effluent to increase in order to treat these harmful substances. This is a normal phenomenon that tends to occur during periods of poor tap water quality. The increase in zinc content in water, in turn, indicates that it eliminates more substances harmful to health, indicating that the performance of the water purifier is excellent.

The zinc content in drinking water is an indicator of sensory traits, and zinc is beneficial to the human body

What does it mean to exceed zinc? China's "Drinking Water Hygiene Standards" stipulates that the zinc content in drinking water should not be greater than 1mg/L, but this indicator is "sensory properties and general chemical indicators". The higher zinc content is prone to milky white in the water, which makes some residents unacceptable to the senses. However, zinc content is not a toxicological indicator. Horizontally, there is no zinc indicator in the WHO Drinking Water Standards. The American Drinking Water Quality Standard stipulates that the zinc content limit is not more than 5mg/L, and specifies that this indicator is a recommended sensory indicator. Many health products and nutritional products can also show that zinc is beneficial to the human body. For example, the instruction manual of "Sanjing brand zinc gluconate oral liquid" states that each 100ml of oral liquid contains 35.3mg of zinc. The content of zinc in children's formula and zinc-added milk is much higher than 1mg/L.

Copper-zinc alloy was first developed and utilized by the United States as an effective water treatment material, in fact, it has a long history of use in China. Brass is the alloy material of copper and zinc, our country used brass as a vessel in ancient times, containing water and food, modern life faucets are mostly brass products, zinc will also overflow and enter water and food when encountering heavy metal pollution, but it is beneficial and harmless to the human body.

Kaineng Environmental Protection has been and will continue to be responsible commitment: our water purifier is connected to normal tap water, if the zinc content of the effluent increases and causes any direct health damage, we are fully responsible.

Scientific and rational view of safety and health related standards

There is a growing focus on water and food safety, but many people are unaware of the requirement of "health" in addition to "safety". Generally speaking: the government manages safety, and its own health is important. But health and safety are not the same and sometimes contradictory. For example, the water plant will add chlorine to the water to avoid the breeding of bacteria and viruses during the transportation of the water, which is for safety reasons; However, from a health point of view, it is better to remove the residual chlorine before residents use it after tap water enters the house, because chlorine is harmful to the human body. The book "Safe Drinking Water and Scientific Drinking Water", written by Fu Jiamu, 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 disinfection", "Its disadvantage is that some disinfection by-products are generated while removing germs, including trihalomethanes, haloacetic acid... Halogoacetic acid and trihalomethanes are 'trigenic' substances (carcinogenic, teratogenic, mutagenic), and these trigens pose a potential threat to human health. ”

The chlorine in the purified water of the water purifier is removed, and such water is of course healthy and good water for drinking. However, according to the "Drinking Water Hygiene Standards", the chlorine content of tap water in residents' homes cannot be less than 0.05mg/L, and the water without chlorine is not up to standard. But for the user, this is healthy drinking water.

Kaineng Eco-friendly products advocate natural methods to remove harmful substances from water and retain beneficial substances, so as to obtain healthy drinking water. The treatment object of Kaineng household water purifier is municipal tap water, and Kaineng 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), Kaineng environmental protection This water purifier can not only effectively remove heavy metals and residual chlorine, but also the zinc content in the water will be within the standard. However, when the quality of tap water fluctuates especially and the residual chlorine and heavy metals seriously exceed the standard, it is easy to have high zinc content, which is a harmless and healthy phenomenon.

In summary, the copper-zinc alloy filter media represented by KDF is a unique filter material in today's water treatment industry that can eliminate residual chlorine and heavy metals in water while retaining beneficial substances. Of course, any kind of water treatment process is not perfect, but it can be perfected by Kaineng engineers through technical means.

As an industrial tourism spot, Kaineng Environmental Protection welcomes visitors from all walks of life

As a listed company in the domestic human settlement water treatment equipment industry, Kaineng Environmental Protection has long been committed to the research and development and manufacture of whole house water purifiers/water softeners according to China's water quality characteristics, as well as terminal water purifiers, commercial purification water dispensers and other products that adopt different technical solutions to meet different water quality requirements of customers. We are pleased to see that tens of thousands of users in Shanghai alone are satisfactorily enjoying the high-quality water purifiers

Kaineng products have been adopted by major events such as the Olympic Games, World Expo, and World Swimming Championships, and nearly 50% of its products are exported to Europe and the United States.
