water softener system
(1) The differences between hard water and soft water are:
1. The material content of water is different: soft water contains no or less soluble calcium and magnesium compounds, while hard water contains more soluble calcium and magnesium compounds.
2. Soft water is not easy to produce soap scale with soap, while hard water is the opposite. Hard water does not cause direct harm to health, but it will bring a lot of trouble to life, such as scaling on water appliances, reduction of washing efficiency of soap and detergent, etc. This can be used to distinguish between hard water and soft water.
3. Hard water can be transformed into soft water after treatment. Hard water after softening refers to the softened water obtained after the content of calcium salt and magnesium salt is reduced to 1.0 ~ 50 mg / L. Using the DC power supply as the power, the ions in the water can selectively pass through the ion exchange membrane to obtain soft water.
⑵ what is hard water and soft water
1. Hard water contains more calcium and magnesium, while soft water contains less calcium and magnesium.
2. Streams and rivers will carry minerals in stones in the process of flow, that is, hard water, steam, rain or snow water without minerals is soft water
3. When soap is used in water, it is difficult for calcium and magnesium to react with soap, and it is hard water without foam.
(3) why is water divided into soft water and hard water
In daily life, it is often seen that some water or boiling water tools will have scale, which is difficult to clean. Some people say that because it is hard water, hard water is prone to scale. Is the water soft or hard? What is the difference between hard water and soft water? "Hard water" refers to water with high hardness, that is, the amount of salt dissolved in water. Calcium and magnesium are the two most common minerals in water. The higher the content of calcium, magnesium and other minerals, the harder the water is. Generally speaking, springs, streams, rivers and some groundwater are hard water, because it is easy to dissolve metal ions in soil and rocks. Rainwater, snow water and artificial distilled water have low mineral content and belong to soft water.
Hard water contains a variety of impurities. Bathing with this water for a long time will lead to less hair and rough skin. In fact, the best way is to use soft water. However, the water softeners on the market range from 1000 yuan to 10000 yuan, and it is troublesome to arrange waterways and circuits in advance. Blackberry jam has found a solution to this problem: change the shower. The water gently softens the shower equipment, which has won the American Industrial Design Excellence Award.
(4) what are soft water and hard water
Hardness of water,
It mainly refers to the content of calcium carbonate and magnesium carbonate, expressed in "mg calcium carbonate / L water" or "ppm".
Soft water refers to water whose hardness is less than 8 degrees.
Hard water usually refers to water whose hardness is greater than 8 degrees.
