Semiconductor ultra-pure water equipment
Thread Content
The factory needs to install a set of ultra-semiconductor ultra-pure water treatment equipment. After consulting several companies, the results were not satisfactory: some stated that the standards should follow the national standard \"Electronic-grade water – 2013 version\", while others said that third-party testing could only achieve levels of 0.1 ppb. Do any experts who have used semiconductor-grade ultra-pure water equipment have any recommendations? It would be best if it’s in the Yangtze River Delta region. (Note: The factory is located in Suzhou; the water used is tap water. The output volume is approximately 0.5 tons per hour, the resistivity is >18 megohms, and TOC
The conventional process is two-stage RO + EDI + polishing mixed-bed resin, or RO + cation resin + anion resin + ordinary mixed bed + polishing mixed bed
