What is hard water?
Hard water refers to water containing more soluble calcium and magnesium compounds. The hardness of the World Health Organization (WHO) defined, depending on the water content of calcium and magnesium ions in the number 1L of water, hardness of less than 120mg / L of soft water exceeds 120mg / L of hard water.
hard water on human health affect it?
hard water will give us the daily life and physical health have a great impact.

How to reduce water hardness?
for people who are not suited to hard water, reduce water hardness is necessary.
want to reduce water hardness, the easiest way is to boil. In the heating process, the calcium and magnesium ions in hard water will precipitate to form scale.
