Softened water and other water differences

Raw water is water that has not been treated. In a broad sense, the water before entering the water treatment process is also known as the raw water of water treatment. For example, the water that the source feeds into the clarifier is called raw water.

Softened water refers to the hardness of the water (mainly calcium and magnesium ions in the water). In the softening process, the water reduces the hardness and the total salt content is unchanged.

Desalinization refers to the extent to which salts (mainly strong electrolytes dissolved in water) in water are removed or reduced. Its electrical conductivity is generally 1.0~10.0μS/cm, resistivity (25℃) (0.1~1.0) ×106·cm, and salt content is 1~5mg/L.

Pure water refers to the strong electrolyte and weak electrolyte in water (such as SiO2.CO2, etc.). To be removed or reduced to an extent. Its electrical conductivity is generally :1.0~0.1μS/cm, electrical conductivity (1.01.010.0)×106ω·cm. The salt content is 1mg/L.

Ultrapure water
Refers to gases, colloids and organic matter (including bacteria, etc.). The conductive medium is almost completely removed in water. It was also removed to a very low level. Its electrical conductivity is generally 0.1~0.055μS/cm, resistivity (25℃)>10×106Ω·cm, salt content is 0.1mg/L. The ideal pure water (in theory) conductivity is 0.05μS/cm, and the resistivity (25℃) is 18.3×106.
