What Are The Safety Standards For Drinking Water?

What are the safety standards for drinking water?

Water pollution is becoming increasingly serious, resulting in great safety risks for people's drinking water. In addition to visible impurities such as mud, red worms, and rust, there are also invisible hazards such as residual chlorine, bacteria, and heavy metals. These all affect people's health. So what are the safety standards for household drinking water?

Suspended matter

Suspended matter in water is particles with a particle diameter of about 10nm-0.1um. Visible to the naked eye. These particles are mainly composed of silt, clay, protozoa, algae, bacteria, viruses and high molecular organic matter, and are often suspended in the water flow. The turbidity of water is also caused by such substances.

Rust

Tap water always has a rusty smell. Many residents living in old communities often encounter this problem. The reason is that the problem usually lies in the galvanized water pipes used. This galvanized pipe is iron on the outside and zinc on the inside. It is easy to rust after water corrosion. Many old communities use this pipe, so the water from the tap at home is yellow and has a rusty smell. Long-term drinking of "rusty water" may cause vomiting, diarrhea, uremia and metabolic disorders.

Heavy metals

Heavy metal pollution mainly comes from industrial pollution, followed by traffic pollution and domestic waste pollution. Industrial pollution is mostly discharged into the environment through waste residue, wastewater, and waste gas, and is enriched in humans, animals, and plants, thus causing great harm to the environment and human health.

Microorganisms

Common microorganisms in water include nine types of organisms, including bacteria, actinomycetes, cyanobacteria, yeast, mold, algae, viruses, protozoa, and metazoa. Their structures are very simple. A cell or a group of cells differentiated into a simple one is an organism that can live independently and undertake all the functions of life activities. Although they are small, their entire body surface has the function of absorbing nutrients, which makes them have an extremely large appetite. If the sugar consumed by a bacterium in one hour is converted into the food that a person needs to eat, then this person will have to eat for 500 years. Microorganisms not only have a large appetite but also eat everything. Organic matter, inorganic matter, and even the latest synthesized complex organic molecules may be eaten by microorganisms. Microorganisms can reproduce very quickly. If it were not for the suppression of the environment and food, the total amount of offspring produced by a bacterium in 24 hours would be equivalent to the weight of 4 earths.

The World Health Organization has made the following six clear regulations on water quality safety.

1. It must be clean water, not just clean in appearance, but the bacterial content must not exceed the standard.

2. Weakly alkaline water, running water with a pH value of 7.5-8.5, is conducive to balancing the pH in our body, neutralizing harmful acidic metabolites in the body, improving the acidification of the body, and keeping our body in an alkaline environment forever. Then the chances of high blood pressure, high blood lipids, and diabetes will gradually decrease.

3. Negative potential water, sufficient oxygen-rich, with reducing properties, neutralizes and removes excess free radicals in the human body, reducing free radicals to non-toxic water metabolism out of the body, and negative ions can help the human body remove harmful oxides: chromates, nitrites, and inert metals. Improving the activity of SOD can protect the blood vessel wall and cell wall from free radical damage, and has anti-fatigue and anti-aging effects.

4. Nutritious water, rich in minerals and trace elements. Including calcium, iron, zinc, selenium, and iodine, which are easily lacking in Chinese residents.

5. Small molecular water, the shape of its water molecules is hexagonal, which is equivalent to the amniotic fluid in the mother's body.

6. Water rich in dissolved oxygen can excrete and metabolize toxins and acidic toxins in our bodies. It keeps us healthy and delays aging.

This is the water purifier. The water purifier can solve the secondary pollution of tap water. After tap water is disinfected with chlorine, it can kill viruses and bacteria, but it cannot remove heavy metals, volatile substances, etc.; after tap water is transported long distances through pipelines, it is susceptible to secondary pollution, so tap water is boiled before drinking, but boiling can only solve the problem of bacteria, but cannot solve the problems of mud, rust, heavy metals, volatile substances, and bacterial corpses. Moreover, the residual chlorine in tap water will produce chloroform after high-temperature boiling. Chloroform is a standard carcinogen, so just boiling it will not fundamentally improve the quality of drinking water, and it will cause serious hidden dangers to health. The water purifier can solve the secondary pollution of tap water.

Water purifiers can effectively separate and remove various pollutants, such as bacteria, residual chlorine, heavy metals, volatile substances, rust, silt, and other impurities and harmful substances in the water. The cost is much lower than other aquatic products. The water tastes good, the water quality is weakly alkaline, small molecules, and strong activity, and can be drunk directly without boiling, so it is increasingly accepted by many families.
