1. The manufacturer prepares a complete URS (user demand) according to its own raw water quality report, its own production capacity and the characteristics of process water.
2. Strictly screen the manufacturers of pure water equipment and try to find some companies with GMP certification experience. Don't worry about money, it's still true that it's worth it now.
3. Strict pure water contract should be signed, and all equipment configuration should meet the requirements of URS.
