When we drink hot water, we find that some hot water is very pure, while some hot water has more scales in desalination equipment. What is the reason for this? Originally, water has hardness, low hardness scale less, high hardness scale more, together to understand their differences.

Characteristics and Differences of Soft Water and Hard Water

Softness and hardness of water depend on the content of calcium and magnesium minerals. The hardness of drinking water determined by water equipment in China's electronics industry is to convert dissolved calcium and magnesium into calcium carbonate, which is measured in unit of calcium carbonate content per liter of water. When the content of calcium carbonate in water is less than 150 mg/liter, it is called soft water, and when it reaches 150-450 mg/liter, it is called soft water. Hard water, 450-714 mg/l is high hard water, higher than 714 mg/l is especially hard water.

Soft water refers to water that does not contain soluble calcium or magnesium compounds or has less content. In natural water, rainwater and snow water are soft water. Springs, streams and rivers belong to temporary hard water, some groundwater belongs to hard water, and distilled water is also artificial soft water.

Hard water refers to water containing more soluble calcium and magnesium compounds. For example, some wells and springs. Hard water is not directly harmful to health, but it will bring a lot of troubles, such as using water to form scale, reducing the washing power of soap and detergent, etc.

Advantages of using soft water in drinking water:

Soft water can thoroughly remove the dirt in the skin cells. After cleaning, the skin has no tightness and exquisite luster. Because soft water is rich in organic minerals and has strong decontamination power, only a small number of unloading paste can be obtained excellent unloading effect, but also loved by beauty lovers. Soft water is used for regular bathing and can relieve dry skin.

When skin injury occurs, the affected area should be washed with soft water first, and then soaked with soft water with degreased cotton, gauze, towel, etc. to gently rub the affected area, which can promote wound healing. Frequent use of soft water shampoo can also make hair soft, natural, not dry, restore natural luster.

The advantages of using soft water in household water are as follows:

Cleaning utensils and porcelain are as clean as new without water stains. The use of detergents is reduced by 53% and the cleaning time of kitchen is reduced by 50%.

The holes of shower nozzles are no longer white scales and water flows in all directions. Toilets, sinks and bathtubs are no longer yellowing and scaling.

When washing clothes, they are soft, clean and fresh in colour. The repair problems caused by the use of hard water in washing machines and other water-using equipment are reduced.

The repair times of wall-mounted stoves or electric water heaters have been greatly reduced, the life of water heaters has been greatly prolonged, the gas and electricity costs of water heaters have been reduced, and the pipes installed in the internal walls of families are not scaled and blocked.
