The process of ultrapure water:

1. The process of using ion exchange is as follows:

Raw water → raw water booster pump → multi-media filter → activated carbon filter → water softener → precision filter → cation resin filter bed → anion resin filter bed → anion resin mixed bed → microporous filter → water point

2. Adopting a two-stage reverse osmosis method, the process is as follows:

Raw water → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → First stage reverse osmosis → PH adjustment → Intermediate water tank → Second stage reverse osmosis (with positive charge on the surface of the reverse osmosis membrane) → Purified water tank → Pure water pump → Microporous filter → Water point

3. The process of using EDI is as follows:

Raw water → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → Primary reverse osmosis machine → Intermediate water tank → Intermediate water pump → EDI system → Microporous filter → Water point
