Why Do You Have To Drink Filtered Water?

It is said that no one can live more than 3 days without water, and water is as precious as gold to the thirsty. Water maintains the life of all things and can also be used to generate electricity. It is also a natural chemical solvent. All industrial production uses this property of water. Water is so important, do you know how many types of water there are? Let's break it down.

Surface water

That is, the water that exists on the surface of the ground without artificial treatment in nature. Surface water includes spring water, stream water, river water, river water, lake water, etc. Most of the surface water is not directly drinkable.

Mineral water

The unpolluted underground mineral water, which gushes out naturally from deep underground or is developed artificially, contains a certain amount of mineral salts and trace elements. Mineral water usually requires strict testing before drinking. For example: when the iodide content in mineral water is 0.02-0.05 mg/L, it is beneficial to the human body, and when it is greater than 0.05 mg/L, it will cause iodine poisoning.

Mountain spring water

Mountain spring water intake points have higher requirements on water sources, which are natural clean water with a quiet environment, no pollution, stable PH value, and minerals and trace elements that are beneficial to the human body.

Groundwater

Groundwater refers to the water that exists in the rock voids below the ground. With its stable water supply conditions, groundwater has become an important water source for agricultural irrigation and urban water, and has become an essential water resource for human society. However, groundwater is usually hard and cannot meet domestic water needs.

Tap water

Tap water refers to the water that meets the corresponding standards produced after purification and disinfection by tap water treatment plants. The tap water in most cities in China has secondary pollution. The tap water must be boiled and cooled before drinking, but it has not yet reached the comprehensive purification standard.

Hard and soft water

Any water that does not contain or contain a small amount of calcium and magnesium ions is called soft water, otherwise it is called hard water. Roughly divided according to the total hardness value of water, the total hardness 0-30ppm is called soft water, and the total hardness above 60ppm is called hard water. In natural water, unpolluted rainwater and snow water away from cities are soft water; spring water, stream water, and groundwater are mostly hard water.

Pure water

It is filtered again on the basis of ordinary drinking water. It does not contain impurities and pollution-free water, which is safer to drink. Household water purifiers can filter pure water. The pure water filtered by high-quality RO water purifiers is pure and does not contain any harmful substances such as various impurities, pollutants, additives, bacteria and viruses, etc., effectively avoiding harmful substances Invasion of the human body. Purified water has many effects in quenching thirst, relieving fatigue, promoting metabolism, and moisturizing the skin.
