The current market standard for industrial water quality is around 18.25MΩ.CM, commonly referred to as ultra-pure water. This type of pure water can be used in the electronics manufacturing industry, laboratories, food processing industry, etc. Is it true that all pure water equipment can produce pure water with a resistivity of 18.25MΩ.CM? What is the typical resistivity of pure water produced by general pure water equipment?
The water treatment technologies for pure water equipment include: deionized water technology, EDI ultra-pure water technology, reverse osmosis water treatment, desalination water treatment, purification water technology, laboratory pure water production, ultrafiltration technology, and softening water technology. The quality of pure water produced varies depending on the water treatment technology used, and the treatment plan is generally customized based on the industrial requirements for pure water quality.
Hongsen Environmental Protection pure water equipment can produce pure water at six levels: 0.5MΩ.cm, 2MΩ.cm, 10MΩ.cm, 15MΩ.cm, 18MΩ.cm, and 18.2MΩ.cm.
The higher the resistivity requirement for pure water, the more various water treatment processes need to be combined to produce it. The resistivity of high-purity water is generally around 18.2MΩ.cm.
When selecting equipment, attention should be paid to the PP filter element, RO reverse osmosis membrane, activated carbon, and ultra-purification column. If the PP filter element is left for a long time, it may show a brown appearance, which indicates it is used. When the water production exceeds 10L per day, the RO reverse osmosis membrane needs to be rinsed more than 5 times. Activated carbon can remove odors and organic substances from the water, and the ultra-purification column is used when high purity water quality is required, achieving ultra-pure water levels through deep desalination of reverse osmosis pure water.
The above is a summary of the approximate resistivity of pure water produced by pure water equipment. Different levels of water quality requirements can be customized according to user needs.
