Definition of ultrapure water

Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including organic and inorganic compounds, dissolved and particulate matter, and dissolved gases, as well as volatile and non-volatile compounds, reactive and inert compounds, and hydrophilic and hydrophobic compounds.

UPW and the commonly used term deionized (DI) water are not the same. In addition to the fact that UPW has organic particles and dissolved gases removed, a typical UPW system has three stages: a pretreatment stage to produce purified water, a primary stage to further purify the water, and a polishing stage, the most expensive part of the treatment process.

What is ultrapure water system?

Ultrapure water system is a kind of pure water treatment equipment used in laboratory environment. Its main purpose is to provide high-purity water source and remove harmful substances in water, such as impurities, ions, bacteria, etc. It can be used for various analytical experiments in the laboratory, such as drug analysis, environmental analysis, food analysis, etc. Ultrapure water system can provide water of various purity according to the needs of the experiment, such as ultrapure water, deionized water, purified water, 、

etc.  

Why we need ultrapure water system?

1. Ensure the quality of the experiment: The laboratory pure water machine can provide high-quality water, which is the basic requirement of many experiments. In experiments in the fields of chemistry, biology, physics, etc., the purity of water has a vital impact on the experimental results. The use of laboratory pure water machines can avoid experimental errors caused by water quality problems, thereby improving the accuracy and reliability of the experiment

2. Improve work efficiency: Laboratory pure water machines usually have a large water storage capacity and the function of rapid water production, which means that experimenters do not need to spend a lot of time waiting for water preparation. This not only saves time and improves work efficiency, but also reduces errors caused by waiting for water preparation during the experiment.

3. Protect experimental equipment: The use of laboratory pure water machines can also protect experimental equipment. High-purity water can reduce corrosion and scaling inside the equipment and extend the service life of the equipment. High-purity water can also improve the performance of the equipment and make the experimental results more accurate.

4. Environmental protection and energy saving: Laboratory pure water machines usually use advanced filtration technology and energy-saving design, which can effectively reduce the waste of water resources and energy consumption. This not only meets the requirements of environmental protection, but also reduces the operating costs of the laboratory.

5. Easy to manage and maintain: Laboratory pure water machines usually have intelligent management systems that can monitor the quality of water and the status of equipment in real time. This allows experimenters to manage and maintain equipment more conveniently, ensuring the normal operation of the equipment and the stability of water quality.

Application of ultrapure water system

You may have applications that require uncommonly pure water standards, such as:

• Biotechnology
• Pharmaceutical
• Cosmetics
• Medical devices
• Food and beverages

1.Medical/Laboratory Processes: In medical processes, pure water's bacteria-free and mineral-free purity ensures the quality and stability of the solution. Pure water extracted by a water purifier can also be used to clean instruments and equipment, and high-purity pure water can also be used for tissue cell culture, blood separation and other experimental projects.

2.Pharmaceutical Industry: Pure water in the pharmaceutical industry can be used to prepare culture media, prepare aqueous solutions, and wash containers and equipment. It can also be used as a solvent for the preparation and manufacture of raw materials in the processing of pharmaceutical and nutritional products, pharmaceutical preparations and analytical reagents.

3.Microelectronics/Semiconductor Manufacturing: In semiconductor manufacturing, pure water can absorb minerals, enhance the effect of detergents, and its dry and residue-free performance can be used to rinse and clean semiconductor wafers. It is also used for wet etching, bacterial testing and other links throughout the manufacturing facility.

4.Automobile: Pure water is less used in the automotive industry, generally for applications in batteries and cooling systems.

5.Cosmetics: Pure water is often used in the testing of hair care, skin care, body care, baby care, sunscreen and cosmetic products, and its stable characteristics can improve the accuracy of data.

‌Main parameters of ultrapure water system

Water inlet requirements: Ultrapure water machines usually use city tap water as inlet water. The inlet conditions include TDS (total dissolved solids) less than 250ppm, temperature between 5-45℃, pressure between 0.02-0.25Mpa, and pH between 3-10.

Water output: The system water output is 120 liters/hour at 25℃, the maximum output of ultrapure water is 2 liters/minute, and the maximum output of reverse osmosis water is also 2 liters/minute.

Water quality indicators: The resistivity of ultrapure water is 18.25MΩ·cm@ 25℃, conductivity is 0.054μs/cm@25℃ (<0.1μs/cm), heavy metal ions <0.1ppb, total organic carbon (TOC) <10ppb, bacteria <1cfu/ml‌

‌Reverse osmosis water indicators‌: TDS ≤ inlet TDS × 5% (stable desalination rate ≥ 95%), divalent ion separation rate 95%-99% (when using new RO membrane)‌
