People say that water is the source of life, but in daily drinking water, many people are still vague about the concept of tap water, pure water, mineral water, and can't tell what is in it. The following story is mainly between the three. The difference.
First, the basic concept of tap water, pure water, mineral water
1. Tap water is natural water processed by water plants. After chlorination or purification treatment, it is chlorinated and disinfected for use as drinking water. Untreated water is not tap water and is not drinkable.
2. Drinking pure water is made from water that meets the sanitary standard of drinking water, and is prepared by electrodialysis, ion exchange, distillation and other appropriate processing methods. It is sealed in a container and does not contain any additives. Drinking water.
3. Mineral water is an uncontaminated underground mineral water that naturally emerges from the depths of the ground or is artificially exposed; contains a certain amount of mineral salts, trace elements or carbon dioxide gas; under normal circumstances, its chemical composition and flow rate Dynamics such as water temperature are relatively stable within the range of natural fluctuations.
Second, the difference between tap water, pure water, mineral water
1. The difference formed
The tap water is flowed from the natural water through the water pipe (or pressurized by the first pump house) into the water plant. Before entering the water purification structure, the coagulant is added - aluminum sulfate or polyaluminum chloride, and lime is added to raise the raw water. After alkalinity and pre-chlorination (depending on the quality of the raw water), it enters the grid reaction tank to form a scented flower, which flows through the honeycomb inclined tube sedimentation tank for sedimentation separation, and then passes through the gas-water backwashing filter for filtration and enters the clean water. After the pool is chlorinated and disinfected, after a certain period of time, it will be pressurized and transported to the water supply pipe network through the secondary pumping station for drinking and production.
Pure water is made from water that meets the sanitary standards for drinking water. It uses a variety of techniques to remove most of the harmful, toxic, and odorous substances in the water, such as heavy metals, trihalomethanes, organic matter, radioactive substances, and microorganisms. The direct and potential hazards of health are then marketed in barrels for people to drink.
