Electronic ultra-pure water standards:

Electronic grade high purity water is divided into five levels: Ⅰ, Ⅱ, Ⅲ, Ⅳ and Ⅴ level

Ultra-pure water process:

Two-stage reverse osmosis + EDI + fine mixed bed or polished mixed bed

Ultra-pure water process description:

In the modern large-scale electronic industry with ultra-pure water system, reverse osmosis + EDI + polishing mixed bed process is the latest development of the process, the application of large systems rarely, we continue to explore, practice and optimization, The water system with advanced technology, low investment, compact structure, large volume of water and high quality has been successfully operated stably. It has solved the defects and shortcomings in the process flow and has well controlled the running cost.
