How to calculate the water and electricity resistance rate of ultra pure water equipment? 

Ultra pure water equipment will determine the water quality of the produced water based on its electrical resistivity, which is closely related to the physical properties and chemical reactions, temperature, purity, and flow rate of the measured material. Recently, a customer inquired with us about how to calculate the conductivity of water produced by ultra pure water equipment. Below is a detailed introduction from Wanda Environmental Protection professional customer service.

The electrical resistivity (or conductivity) of water is influenced by the purity, temperature, and various factors in measurement. The measurement of pure water electrical resistivity (or conductivity) is achieved by selecting a dynamic measurement method and using temperature compensation to convert the measured value into a resistivity of 25C for easy measurement and comparison.

The resistivity of water refers to the resistance between the opposite sides of a 25px cube at a certain temperature, measured in S2 M or MS2. The conductivity of mo is the reciprocal of the resistivity, expressed in s/cm (or μ S/cm). The electrical resistivity (or conductivity) of water reflects the amount of salt in the water. It is an important indicator of the purity of water. The higher the purity of water, the lower its salt content, and the higher its electrical resistivity (conductivity).

Reasons for Unstable Resistivity of Ultrapure Aquatic Water and Electricity

1. The salt content in the inlet water is too high.

2. The C02 content in the inlet water is too high.

3. The pH value of the influent deviates too much from the neutral value: the pre-treatment cannot meet the EDI influent conditions. If the salt content of the raw water is high, it is recommended to use a two-stage R0 reverse osmosis equipment as the pre desalination

Maintain conductivity between 1-3 μ S/cm is preferred. The inlet water has a high content of C02, so it is recommended to use a degassing membrane or degassing tower to remove C02. The pH deviates too much from the neutral, and pH adjustment is used to

The pH value of EDI inlet water should be between 7 and 8.

Ultra pure water equipment can effectively remove impurities from raw water, can operate continuously, provide 24 hours of water supply, and maintain a long-term stable outlet resistivity of over 15M&2 CM. EDI ultra pure water technology

There are great advantages and development prospects in process design.
