Is reverse osmosis process or deionization used for the production of pure water in the semiconductor industry

As is well known, the electronic semiconductor industry has extremely high requirements for pure water, and the water quality needs to reach a certain standard before it can be used. With the increasing number of pure water equipment models in the market, even after determining which model, the processing workshop mainly focuses on water treatment technology. The quality of pure water after different water treatment processes is different.

At present, the common water treatment processes in the market include reverse osmosis technology, bipolar reverse osmosis, deionized water technology, edi ultra pure water, etc. The pure water used in the semiconductor industry mainly includes reverse osmosis and reverse osmosis processes. 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 the water through reverse osmosis membranes.

Deionized water technology removes anions and cations from water through exchange resins, but there are still some soluble organic compounds present in the water. Therefore, this is a type of industrial water that does not have high water quality requirements.

Hongjie Water adopts a combination of reverse osmosis water treatment process and deionization technology for the semiconductor industry pure water process, and its pure water quality can reach 18.2M Ω. CM. 

The selection of water treatment process is not only related to the water quality of the water used, but also to the quality of the raw water. The specific water treatment process flow is directly referred to Hongjie Water for scheme inquiry.
