What factors affect the resistivity of pure water produced by EDI ultrapure water equipment?
Release time:2022-09-22
Many industries require industrial pure water for product processing and manufacturing, and the quality of industrial pure water directly affects the use of product equipment and laboratory results. Therefore, industrial water has extremely high requirements for the quality of pure water. During the production of pure water, sometimes the electrical resistivity of the effluent water cannot meet the specified requirements. Today, we will learn about the factors that affect the electrical resistivity of pure water produced by EDI ultra pure water equipment?
The customization of pure water equipment is mainly based on the hourly water consumption, with specifications ranging from 0.25T/H, 0.5T/H, 1T/H, 5T/H, 10T/H, 15T/H, 100T/H... 1000T/H. The main reason for setting the size of the equipment specifications is that the produced pure water will be affected by natural factors and the electrical resistivity will decrease over time.
The resistivity of pure water produced by EDI ultrapure water equipment is mainly affected by factors such as water temperature, pretreatment, and reverse osmosis membrane.
In general, the inlet water temperature of the equipment is around 25 degrees Celsius. After the reverse osmosis membrane is put into use, the amount of filtered water will gradually decrease. Therefore, many times when choosing, the demand for water production will be increased.
The pretreatment of raw water is mainly aimed at removing impurities from the water, which can prolong the service life of the equipment while preventing the impact of impurities such as particulate matter in the water on the electrical resistivity of the effluent.
When the reverse osmosis membrane needs to be cleaned in a timely manner after a period of use, excessive impurities on the reverse osmosis membrane can also lead to an increase in conductivity.
The quality of incoming water varies in different places, and when carrying out pure water treatment, it is necessary to first test the quality of the raw water before determining the pure water treatment process.
