Is reverse osmosis or deionization used for pure water production in the semiconductor industry
Release time:2023-05-08
The electronic semiconductor industry has extremely high requirements for pure water, and the water quality needs to meet certain standards before it can be used. With the increasing number of pure water equipment models on the market, even after determining which model to use, the processing workshop mainly focuses on water treatment processes. The quality of pure water treated by different water treatment processes is different.
The common water treatment processes on the market currently include reverse osmosis technology, bipolar reverse osmosis, deionized water technology, EDI ultrapure water, etc. The pure water used in the semiconductor industry mainly includes reverse osmosis and reverse osmosis technology. Which of these two water treatment processes is more suitable.
The reverse osmosis water treatment process can remove about 96-99% of salt substances in water, and achieve water purification by intercepting organic matter, bacteria, ions, pollutants, etc. contained in water through reverse osmosis membranes.
Deionized water technology removes anions and cations from water through exchange resin, but there are still some soluble organic compounds in the water, making it a suitable industrial water production method that does not require high water quality.
Shanghai Yishuo adopts a combination of reverse osmosis water treatment technology and deionization technology for the pure water process in the semiconductor industry, and its pure water quality can reach 18.2 M Ω CM。
The choice of water treatment process is not only related to the quality of the water used, but also to the quality of the raw water. The specific water treatment process flow can be directly queried at Shanghai Yishuo.
