Anonymous users2024-02-06Some time ago, the country came up with a new standard, which is very demanding. You can find the information of this standard when you go to the "Gongbiao Network"!
Standard number: GB 17323-1998
Standard name: bottled purified water.
Standard Status: Active.
Date of implementation: 1999-1-1
Promulgating Departments: State Bureau of Quality and Technical Supervision.
Brief introduction: This standard stipulates the technical requirements, test methods, inspection rules and markings, packaging, transportation and storage requirements for bottled drinking water.

Anonymous users2024-02-05Summary. The state requires the ozone concentration of purified water to be between ozone solubility in water applications. The low value is used as the minimum concentration required for water disinfection and purification, and the high value is used as the achievable concentration value of "ozone water disinfectant".
Tap water ozone is opened, and the solubility value of the international standard is kept for 4 minutes, that is, the CT value is.
The residual ozone concentration in the water is kept at the effect for 5 10 min to achieve the purpose of disinfection.
What is the ozone concentration of purified water required by the national standard? The minimum amount can be sterilized!
Hello, shouting that I am a teacher of Xiaoxiang, an expert in education, an expert in education Q&A, I have consulted 1000+ people, I have seen your question, and quickly prepare the answer to the "National Standard for Pure Water Ozone Concentration" for you, give me two minutes of time code words, thank you Zheng Qianbi, please wait a while.
The state requires that the ozone solubility of pure water is between hail concentrations and water applications. The low value is used as the minimum concentration required for water disinfection and purification, and the high value is used as the achievable concentration value of "ozone water disinfectant". The ozone of the tap sail water is opened, and the international conventional standard is the solubility value of the acreage, which is maintained for 4 minutes, that is, the CT value is.
The residual ozone concentration in the water is kept at the effect for 5 10 min to achieve the purpose of disinfection.

Anonymous users2024-02-04Legal Analysis: The safety standards for ozone are:
Legal basis: Measures for the Administration of Mandatory National Standards of the State Administration for Market Regulation
Article 35 The numbering of mandatory national standards consists of the mandatory national standard code (GB), sequence number and era number.
Article 51 Where a mandatory national standard involves a patent, it shall be implemented in accordance with the relevant administrative provisions of the national standard concerning patents.

Related: The Chinese National Standard GB T 23960-2009 stipulates the definition, classification, requirements, test methods, marking, packaging, transportation and storage of high-concentration ozone water. Among them, high concentration ozone water is defined as an aqueous solution with a chemical formula O3 and a solubility greater than g 100 ml containing more than 60 mg l of ozone.
The standard stipulates the technical requirements for high-concentration ozone water, including ozone gas content, pH value, solubility, impurity content, etc., and also describes the test methods of high-concentration ozone water in detail to ensure that the quality of high-concentration ozone water meets the national standards and related requirements. <>
National Standard for High Concentration Ozone Water.
National standards for the use of high-concentration ozone water.
Dear, I'm glad to answer your <>
The national standard for high-concentration ozone water meets the requirements of the GB2760-2011 standard, and is mainly used for bleaching, preservation, antiseptic feasts of aquatic products, dried fruits and other foods, as well as sterilization and disinfection <> of food production equipment and containers

Anonymous users2024-02-02The concentration of ozone in the air is an important indicator of air quality. Stinky potato cover oxygen is a toxic gas that can cause harm to the respiratory system if inhaled too much by the human body. As a result, various countries and regions have issued standards to safeguard people's health and quality of life.
Ozone concentration standards vary in different regions. In China, for example, the national standard stipulates that the hourly average ozone concentration in residential and commercial areas shall not exceed 160 microgram cubic meters, the daily average ozone concentration shall not exceed 100 microgram cubic meters, and the annual average ozone concentration shall not exceed 60 microgram cubic meters. In the United States, the national standard stipulates that the 8-hour average concentration of ozone must not exceed 70 parts per billion (ppb).
Under the strict implementation of ozone concentration standards, the harm of ozone to the human body can be effectively avoided. However, ozone** and the mechanisms of formation vary from region to region, so in practice the standards for ozone concentrations implemented need to vary from place to place. For example, industrial pollution and vehicle emissions can lead to an increase in ozone concentrations, so ozone concentrations in cities tend to be high.
In addition to the regulations and regulations, there are also steps that individuals can take to reduce the hazards of ozone. For example, avoid strenuous exercise in an environment with high ozone concentrations, and choose a cleaner environment for outdoor activities. Strengthening ozone monitoring and control plays a very important role in ensuring people's health and safety.
In short, ozone concentration standards in the air represent an important task to protect people's health and improve their quality of life. It is necessary for all sectors of society to work together to strengthen ozone monitoring and governance, and effectively reduce the impact of ozone on the human body and the environment. <>
Difference Between Purified Water and Distilled Water.
Purified water is a clean aerobic molecule that contains trace amounts of mineral plants needed by the human body, and is also living water (fish do not die in it). Whereas distilled water is stagnant water (without oxygen the fish will die immediately in it). Purified water is not the same thing as distilled water at all, so distilled water cannot be compared to purified water. >>>More
Look at the concept of water purifier, if some minerals are retained, it is fine, because a large part of the minerals in the human body are ingested through water, and the intake from food alone cannot be satisfied. If the mineral content in the water is low or even none, then you should usually supplement with mineral tablets. >>>More
Water does not contain other trace elements.
Tap water and purified water, on the other hand, contain substances other than water and are not pure. >>>More
I think there are two main reasons:
1.That is, purified water can be produced in large quantities, and the production process is relatively simple. The natural mineral water source is less selective, and the output will not be very large, and the real mineral water ** is relatively small. >>>More
Boiled water or purified water Because they are soft water, there is no harm to the human body And pure water is hard water, which can be harmful if you drink it for a long time In recent years, with the change of people's consumption concepts and the enhancement of environmental awareness, mineral water, mineralized water, pure water, distilled water and space water have appeared on the market. Manufacturers of mineral water and mineralized water advertise that their drinks contain a variety of minerals needed by the human body, which can dispel diseases and strengthen the body, and are the best drinks; Some also claim that "mineral water is better than pure water, distilled water and space water, and these pure waters not only remove the harmful components of the human body, but also discard the beneficial components of the human body". Not to be outdone, the manufacturers of space water and pure water say that pure water has high purity, which is easy to dissolve food nutrients in water and be absorbed by the human body, and is easy to discharge harmful substances in the human body; Some even claim that "the human body does not need to absorb minerals from water, mineral water is harmful to the human body, and the biggest danger is the formation of stones". >>>More
