Laboratory Ultra-Pure Water Equipment RUPC

Xinrui Laboratory Ultrapure Water System is a water purification equipment for laboratory use. It is a water treatment device that removes all solid impurities, salt ions, bacteria, viruses, etc., from water through methods such as filtration, reverse osmosis, electrodialyzer, ion exchanger, and ultraviolet sterilization. Xinrui Laboratory Ultrapure Water Equipment is widely used in industries such as pharmaceuticals, electronics, chemicals, and biological and physical laboratories. Laboratory ultrapure water systems typically produce two types of water: pure water and ultrapure water.
Laboratory ultrapure water systems are generally divided into four units: pretreatment, reverse osmosis, ion exchange, and terminal ultrafiltration. Tap water first passes through the pretreatment unit to remove larger particles, suspended solids, and some organic matter. It then enters the reverse osmosis unit, where ionic substances and macromolecular substances (such as viruses, microorganisms, etc.) are removed by retention. After that, it goes through the ion exchange unit to purify and ultrapurify the residual trace ions left after membrane removal, reducing the ion content in the water to trace levels. Finally, technologies such as UV and ultrafiltration ensure that microorganisms, organic matter, and pyrogens in the ultrapure water meet the requirements of various experimental applications.
Working Principle of Xinrui Laboratory Ultrapure Water System
The working principle of the laboratory ultrapure water system is that tap water undergoes pretreatment through precision filter cartridges and activated carbon filter cartridges to filter out particles such as sediment and adsorb odors, making the tap water cleaner. It then passes through a reverse osmosis device for water purification and desalination. The purified water is stored in a storage tank, and its quality can meet the national tertiary water standard. Meanwhile, the wastewater produced by the reverse osmosis device is discharged. Reverse osmosis pure water undergoes deep desalination treatment through a purification column to obtain Grade 1 water or ultrapure water. Finally, if there are special requirements, ultraviolet sterilization or microfiltration, ultrafiltration, and other devices are added after the ultrapure water to remove residual bacteria, particles, pyrogens, etc., from the water. Precision filter cartridges, activated carbon filter cartridges, reverse osmosis membranes, and purification columns are all materials with a relative lifespan. Precision filter cartridges and activated carbon filter cartridges actually protect the reverse osmosis membrane.

Technical Principle of Xinrui Laboratory Ultrapure Water System
Ion exchange in ultrapure water systems is a special solid adsorption process that occurs in electrolyte solutions with ion exchangers. Generally, ion exchangers are water-insoluble solid granular materials, i.e., ion exchange resins. They can absorb certain cations or anions from the electrolyte solution and release another type of ion with the same charge symbol in equivalent amounts into the solution. This is known as ion exchange. Based on the types of ions exchanged, ion exchangers can be divided into two major categories: cation exchangers and anion exchangers.
