Pure water refers to H?O without impurities, referred to as purified water or pure water, is pure, clean, does not contain impurities or bacteria in the water, such as organic pollutants, inorganic salts, any additives and various types of impurities, is in line with the hygiene standards for drinking water as the raw water. Through the electrodialyzer method, ion exchanger method, reverse osmosis, distillation and other appropriate processing methods and made, sealed in containers, and does not contain any additives, colorless and transparent, can be directly consumed.
So it does not contain minerals.
Main Function:
Water containing too many minerals in the body will cause unnecessary burden on the human body, and there are minerals that the human body may not be able to absorb, and if the long-term accumulation of the body, it will have a direct impact on the human body's health.
But pure water for a short period of time to help excrete toxins in the body, long-term drinking may lead to excessive lead content in the body. Because calcium and lead in the human body is a competitive relationship, an increase in one side, the other side will decrease, and vice versa, a decrease in one side, the other side will increase, pure water in the absence of calcium, the human body will absorb a large amount of lead, which leads to lead in the body of the excessive lead content.
The reverse osmosis membrane that filters pure water removes the bacteria and impurities in the water, but also filters out the trace elements in the water that are beneficial to the human body, and long-term consumption will lead to a lack of trace elements in the human body, resulting in stunted growth in children and adolescents, and causing trace element deficiencies in older people.
Preparation process:
Pure water can be produced by electrodialysis, ion exchanger, reverse osmosis, distillation and other appropriate processing methods, sealed in containers, and does not contain any additives, colorless and transparent, and can be consumed directly.
Pure water for drinking process for:
Pollution prevention and control:
Measures to control microbial contamination Pure water is a special kind of product, once contaminated by a few microorganisms, it may exceed the standard, and even flocculent precipitation and other consequences. Therefore, the control of microbial contamination is a very important work of the production enterprise. The above analysis shows that the measures to control microbial contamination of pure water should be comprehensive, and can not overemphasize one aspect and ignore other aspects, because any part of the production process is contaminated, will affect the quality of the product.
1, strengthen its own health management, strengthen the awareness of the quality of food hygiene, designate a leader responsible for health work, the establishment of a full-time health inspection agency, strengthen the water source, packaging, filling room air and product testing, the development of water management, sterilization, filling, packaging to personal hygiene in all aspects of the hygiene management system, and designate a person to supervise the implementation of the strengthening of food hygiene knowledge training and learning. Focus on mastering sterilization methods and clear microbial contamination of key links easily.
2, according to the characteristics of the water source, rational and scientific design of the production process, equipped with the necessary water treatment and production equipment, select the sterilization system in line with the water disinfection. China's mineral water and pure water more than the use of ultraviolet light, ultrafiltration and ozone as sterilization and disinfection sterilization facilities. But many years of experience has proved that the first two kinds of poor reliability, is the main factor causing product failure, and the use of ozone sterilization is considered to be the best method at present.
3, regularly strengthen the production of the whole process of piping, containers and filters and other related facilities to clean and disinfect, do a good job of bottles, caps and filling room disinfection. It is understood that most manufacturers of pipelines and packaging disinfection using chlorine dioxide (ClO2), the drug has a strong oxidation and disinfection, but to strengthen the quality of disinfection drugs to ensure its disinfection effect.
