Laboratory ultrapure water machines are roughly 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 ultra-purify the residual trace ions left after membrane removal, reducing the ion content in the water to trace levels. Finally, technologies like UV and ultrafiltration ensure that microorganisms, organic matter, and pyrogens in the ultrapure water meet the requirements of various experimental applications.

As a top-tier pure water system manufacturer in China, since its establishment, Xinrui has adhered to the philosophy of "Your needs, we create" and the spirit of "professionalism, stability, progress, and innovation." It has consistently focused on the innovation and development of laboratory, medical, and industrial ultrapure water products, committed to providing professional and comprehensive pure water system solutions for laboratory, medical, and industrial clients.

Ultrapure water is produced using distillation, deionization, reverse osmosis technology, or other appropriate supercritical fine techniques. Today, ultrapure water is widely used in fields such as biology, medicine, and the automotive industry. This water contains almost no impurities other than water molecules (H?O), and certainly no bacteria, viruses, chlorine-containing organic matter, or the mineral trace elements required by the human body. Ultrapure water has no hardness, a sweet taste, and is often referred to as soft water. It can be consumed directly or boiled for drinking. Ultrapure water is a level that is difficult to achieve through general processes. For example, if the resistivity of water is greater than 18 MΩ*cm and close to 18.3 MΩ*cm, it is called ultrapure water.

Using methods such as pretreatment, reverse osmosis technology, ultrapurification treatment, and post-treatment, the conductive media in the water are almost completely removed, and non-dissociating colloidal substances, gases, and organic matter are reduced to very low levels in water treatment equipment.

The desalination core component of the ultrapure water system equipment is the imported reverse osmosis membrane module. The ultrapure water system equipment is typically composed of the pretreatment section, the reverse osmosis host section, and the post-treatment section.

Technical Requirements
