The pharmaceutical factory’s ultrapure water device is designed specifically for pharmaceutical factories that use purified water, high-purity purified water, and injection water. The purified water produced by the pharmaceutical factory’s ultrapure water device can be used for vessel cleaning, sterile high-purity purified water suitable for ultrasonic cleaning, water for oral and tablet drug preparation, pure steam generator water, injection water suitable for injection drug packaging cleaning and injection drug preparation water, etc. The ultra pure water equipment in pharmaceutical factories mainly adopts EDI ultra pure water technology, which is a new desalination technology formed by the organic combination of electrodialysis technology and ion exchange technology. It can effectively remove all ions from water, and the effluent resistivity can be stable at 15M Ω CM or above, continuous operation, no chemical pollution, high water utilization rate.
