What Are the Standards for Using Pure Water in Various Industries?

With the technological development of various industries, the demand for pure water is increasing. Traditional water purification systems can no longer meet their needs, which highlights the advantages of professional pure water equipment. Industrial pure water equipment can meet the water requirements of various industries. Every industry has its own standards for pure water. Below is a brief overview:

1. Conductivity ≤ 10 μS/cm: Animal drinking water (pharmaceutical), pure water for general chemical raw material preparation, pure water for food industry preparation, deionized pure water for rinsing in general electroplating, pure water for hardening and desalination in textile printing and dyeing, pure water for polyester chip production, pure water for fine chemicals, purified drinking water for domestic use, and other pure water with the same quality requirements;

2. Conductivity ≤ 4 μS/cm: Pure water for electroplating chemical production, pure water for surfactant production in the chemical industry, purified medical water, pure water for liquor production, pure water for beer production, purified drinking water for domestic use, pure water for general cosmetics production, pure water for hemodialysis machines, and other pure water with the same quality requirements;

3. Resistivity 5~10 MΩ/cm 

4. Pure water with resistivity: 10~15 MΩ·cm: Used in animal laboratories, for rinsing glass shell coatings, electroplating, coating glass, and other applications requiring the same purity.

5. Pure water with resistivity ≥15 MΩ·cm: Used in pharmaceutical production, oral liquid production, high-end cosmetics production (deionized), electronics coating, optical material cleaning, electronic ceramics, advanced magnetic materials, and other applications requiring the same purity.

6. Pure water with resistivity ≥17 MΩ·cm: Used in animal laboratories, for rinsing glass shell coatings, electroplating, coating glass, and other applications requiring the same purity. Softened pure water for magnetic material boilers, pure water for sensitive new materials, pure water for semiconductor material production, pure water for advanced metal materials, pure water for anti-aging material laboratories, pure water for non-ferrous and precious metal smelting, pure water for nano-scale new material production, pure water for aerospace new material production, pure water for solar cell production, pure water for pure water wafer production, pure water for ultrapure chemical reagent production, high-purity water for laboratories, and other pure water with the same pure water quality requirements;

7. Pure water for ITO conductive glass manufacturing with resistivity ≥18 MΩ.CM, pure water for laboratory use, pure water for electronic grade cleanroom cloth production, and other pure water with the same pure water quality requirements.
