The laboratory ultrapure water machine is a water level gauge of laboratory water purification equipment. It is a water treatment device that removes all solid impurities, salt ions, bacteria and viruses in water by filtration, reverse osmosis, electrodialysis, ion exchanger, EDI, ultraviolet sterilization and other methods. Laboratory ultrapure water equipment testing is used in medicine, electronics, chemical industry and other industries. In biophysical and chemical laboratories and other industries, the laboratory's ultrapure water machine can usually produce two specifications of pure water and ultrapure water.
The working principle of the laboratory ultra-pure water dispenser is: the tap water is carefully filtered, the activated carbon filter is pre-treated, the particulate matter such as sediment is filtered, the odor is adsorbed, the tap water becomes cleaner, and then the water quality is purified through reverse osmosis The device performs desalination. The water quality of the pure water intake water storage tank can reach the national three-level water standard, and can discharge the waste water generated by the reverse osmosis device.
The reverse osmosis pure water is subjected to deep desalination treatment by the purification column to obtain first-grade water or ultra-pure water. Finally, if the user has unique requirements, ultraviolet sterilization or micro-filtration and ultra-filtration devices are added to remove the remaining bacteria in the ultra-pure water , Particles, heat sources, etc. The filter element, activated carbon filter element, reverse osmosis membrane, purification column, etc. are relatively raw materials for life. The filter element and activated carbon filter element are actually the guardians of the reverse osmosis membrane.
If they fail, then the reverse osmosis membrane load increases, reducing short-lived, if the network startup continues, and then falls when water quality occurs, it will be responsible for improving the purification column, and the purification column life will be shortened. The final result is an increase in the use of ultrapure water as capital.
