In today’s serious water pollution, tap water is no longer the first choice for people’s daily drinking water. As pure as before. In my memory, what impressed me the most was when a customer told me that “the tap water is undrinkable”. So what about boiled tap water? Which is safer, boiled tap water or purified water?
Pure water, referred to as clean water or pure water, is pure, Clean water that does not contain impurities or bacteria is made from water that meets the sanitary standards for drinking water as raw water through electrodialysis, ion exchange, reverse osmosis, distillation and other appropriate processing methods , sealed in the container, without any additives, colorless and transparent, can be drunk directly.
Pure water, pure water quality, does not contain any harmful substances and bacteria, such as organic pollutants, inorganic salts, any additives and various impurities, effectively avoiding various germs Invasion of the human body.
The advantage of pure water is that it can effectively and safely replenish water to the human body, and has a strong solubility, so it has a strong affinity with human cells and can promote metabolism. Purified water is the first choice for making tea. Brewing tea with pure water will ensure good tea quality and will not leave scale.
Tap water is produced after purification and disinfection by tap water treatment plants Water for people’s living and production that meets the national drinking water standards. It mainly draws rivers, lakes, groundwater, and surface water through the water intake pumping station of the water plant. The water plant is processed by the water plant in accordance with the “National Drinking Water Relevant Hygienic Standards” through processes such as sedimentation, disinfection, and filtration, and finally transported through the water distribution pumping station. to each user.
Because tap water is transported by pump power or gravitational potential energy, it is affected by the structure of the pipeline, especially the material of the water storage tower and pipeline (stainless steel metal pipe, PVC, etc.), The water supplied to users by pumps through water transmission and distribution pipelines often does not meet the sanitary standards for drinking water.
Due to serious water pollution, the water source is polluted, the water pipes are rusted and bacteria grow after long-term use, and the treatment and disinfection of tap water are not rigorous. Therefore, tap water in most places does not meet the quoted standards.
Boiled tap water
Generally, tap water should be boiled drink. But boiling water only kills most of the bacteria in the tap water and keeps the ions.
When water is boiled, the oxygen content in the water will drop sharply. When raw water is boiled, the chlorine in the water will mix with organic compounds, turning nitrate into nitrous acid salt, so that the human hemoglobin becomes nitrosylglobin, and the red blood cells lose their oxygen-carrying capacity. Therefore, it is not safe to drink tap water after boiling.
If the water is boiled and left for too long, it will become aged water, and the toxic substances in the aged water will increase as the water storage time increases.
Therefore, tap water is not pure water after being boiled. It is best to drink the boiled water on the same day. Experiments have shown that drinking boiled water that has been naturally cooled and left for no more than 6 hours is the most beneficial to human health. Compared with boiled tap water, pure water is much safer and can be safely drunk.
