What is an ultrapure water system?
Ultrapure water system is a highly efficient water purification equipment, which is specially used to remove all impurities in water and provide extremely high purity water. It is used in fields that require extremely strict water quality, such as chemical analysis, laboratory research, semiconductor manufacturing, pharmaceutical production, etc.
Working principle:
Ultrapure water system combines reverse osmosis, deionization, ultrafiltration, ultraviolet disinfection and other technologies through multiple purification stages to further improve the purity of water and reach the standard of ultrapure water. The general treatment process is as follows:
Pretreatment:
Activated carbon filtration: removes chlorine, odor, and volatile organic matter from water.
Sedimentation filtration: removes large particles of impurities in water, such as sand, soil, etc.
Softening treatment: removes calcium and magnesium ions from water and reduces the formation of scale.
Reverse Osmosis Treatment:
The water is treated with reverse osmosis membranes to remove most dissolved ions, bacteria, viruses, and organic matter. RO membranes can remove most dissolved solids in water, usually reducing the total dissolved solids in the water to very low levels.
Deionization Treatment:
The remaining ions in the water (such as sodium, calcium, magnesium, chloride, etc.) are removed through ion exchange resins. This step further removes almost all dissolved ions in the water, ensuring that the water quality reaches a very high purity.
Ultrafiltration Treatment:
The ultrafiltration process can remove tiny particles, microorganisms, etc., further ensuring the purity of the water quality.
Ultraviolet Disinfection:
Ultraviolet lamps are used to disinfect bacteria and viruses in the water to ensure that there is no microbial contamination in the water.
Final Treatment:
After all the purification treatments, the water will be further removed through some precision filters to ensure the transparency and purity of the water.
Features:
High purity:
Ultrapure water usually has a very low conductivity (generally less than 0.1 μS/cm), which means that it contains almost no soluble ions, microorganisms or organic pollutants.
Stability:
Ultrapure water purification systems can stably provide high-quality water sources to ensure accuracy and reliability in experiments or industrial production processes.
Multi-stage purification:
Ultrapure water systems usually include multiple stages of treatment, each with a specific role to ensure that the water quality reaches extremely high standards.
Intelligence:
Ultrapure water systems are equipped with intelligent monitoring systems to detect water quality in real time, automatically adjust operating status, and promptly remind maintenance or replacement of filter materials.
Application areas:
Chemical analysis: Water source for high-precision analytical instruments to prevent impurities in the water from affecting the analysis results.
Biological experiments: Ultrapure water is required in cell culture, molecular biology experiments, etc. to ensure the accuracy of experimental results.
Semiconductor manufacturing: Ultrapure water is used in chip manufacturing and cleaning processes to remove tiny impurities or contaminants.
Pharmaceutical industry: Ultrapure water is generally used in the preparation of injections to ensure product quality.
Laboratory research: Ultrapure water generated by the laboratory ultrapure water system can prevent impurities in the water from affecting experimental data.
