Yes, if the technology is immature, you are most afraid of secondary pollution.
Common drinking water:
(1) Purified water
"If the water is too clear, there will be no fish." The water is too clear and contains very few minerals, causing small molecule water to turn into large molecule water, which cannot easily pass through the cell membrane of the human body and loses activity. Long-term drinking of this water will reduce the body's immune function and cause the loss of some beneficial nutrients in the body. In particular, children, the elderly and pregnant women suffering from cardiovascular disease and diabetes are less likely to drink this water.
(2) Oxygen-rich water
When you drink this kind of water, when the oxygen molecules in the water enter the body, a small part of them will be converted into superoxide free radicals, which are what cause human aging. One of the biggest culprits.
(3) Mineral water
Mineral water should be said to be healthy water, because it comes from nature after all. But not all mineral water is like this. This first depends on whether its water source is contaminated, secondly it depends on the depth of its water intake, and finally it depends on its processing and packaging process. Especially this last item is very important. Natural water is living water and is extremely susceptible to "secondary pollution", especially when it is put into buckets or bottles. Of course, this does not deny the benefits of mineral water. For now, mineral water is still the best we can drink. It’s better water to drink, but it needs to be pointed out that mineral water is still macromolecular water.
(4) Electrolyzed ionized water
Ionized water can be divided into positive and negative according to the oxidation-reduction potential (ORP) value.
1. Positive ionized water
When the ORP value is positive, it is positive ionized water. It is alkaline, has high oxygen content, has astringent and bleaching effects, and can be used for beauty and hairdressing. When its positive potential reaches 1000mV, it has an instant killing effect on bacteria and other microorganisms.
2. Negative ion water
When the ORP value is negative, it is negative ion water. It is alkaline and has a sweet taste. It can be said to be the best drinking water at present. It is both drinking water, health water and medical water. In the process of producing this kind of water, the tap water is generally purified first, and then through the positive and negative electrodes, the water molecule clusters are broken up, made smaller, and rearranged under the action of the electric field, so that the ORP of some of the water is at a positive potential, and the ORP of the other water is at a positive potential. The ORP of part of the water has a negative potential, and finally positive ion water and negative ion water are obtained through membrane separation technology. Under the action of the electric field, ions in the water will migrate, with positive ions moving toward the cathode and negative ions moving toward the anode. Therefore, after this water is left for a certain period of time, the ORP value will change, which means that the shelf life is limited, and it usually returns to ordinary tap water after 30 hours. Due to this shortcoming, it is difficult to carry out industrial production. In recent years, small electrolytic ionized water generators have developed rapidly and begun to enter households. In newly built homes in Japan, electrolytic ionized water generators are generally installed. It has a history of use in our country for more than 10 years.
Kangfuxing electrolyzed water machine has many invention patents and is used by many government agencies, banks, and high-end residential areas. I have also discussed with my family about buying one,,,
