Definition of soft and hard water
What is hard water? What is soft water?
We use the index "hardness" to measure the total concentration of calcium and magnesium ions in water. The equivalent of 10 mg of calcium oxide per liter of water is 1 degree, the hardness is less than 8 degrees as soft water, and the hardness is higher than 8 degrees as hard water.
"Hard water" means that the water contains a lot of dissolved minerals, especially calcium and magnesium. Hard water does not pose a direct health hazard, but it can bring a lot of troubles to life, such as scale formation on water appliances, and reduced washing efficiency of soaps and detergents. In daily life, mineral water and tap water are hard water; rainwater and snow water are soft water.
What are the hazards of hard water?
1. Washing clothes with hard water wastes water. Due to the formation of insoluble precipitates when reacting with soap, the washing effect is reduced.
2. In industry, mineral precipitation in hard water will cause boiler scale, hinder heat conduction, and even lead to boiler explosion in severe cases. Due to the problem of hard water, the maintenance and replacement of equipment and pipelines in the industry cost tens of millions of yuan every year.
3. The harm of hard water to the human body. People who do not drink hard water occasionally drink hard water, which will cause gastrointestinal disorders; cooking fish and vegetables with hard water will destroy or reduce the nutritional value of food because it is not easy to cook; making tea with hard water will cause Change the color and aroma of tea and reduce its drinking value; using hard water to make tofu will not only reduce the yield, but also affect the nutritional content of tofu.
