(1) The technological process of ultrapure water equipment is:

1. Pretreatment system → reverse osmosis system → intermediate water tank → coarse mixed bed → fine mixed bed → pure water tank → pure water pump → ultraviolet sterilizer → polished mixed bed → precision filter → water object (≥18MΩ.CM) (traditional Craft).

2. Pretreatment → reverse osmosis → intermediate water tank → water pump → EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polished mixed bed → 0.2 or 0.5 μm precision filter → water object (≥18MΩ.CM) (the latest technology) .

3. Pretreatment→first-stage reverse osmosis→dosing machine (PH adjustment)→intermediate water tank→second-stage reverse osmosis (positive charge reverse osmosis membrane)→pure water tank→pure water pump→EDI device→ultraviolet sterilizer→0.2 or 0.5μm precision filter → water object (≥17MΩ.CM) (the latest technology).

4. Pretreatment → reverse osmosis → intermediate water tank → water pump → EDI device → pure water tank → pure water pump → ultraviolet sterilizer → 0.2 or 0.5 μm precision filter → water object (≥15MΩ.CM) (the latest technology).

5. Pretreatment system → reverse osmosis system → intermediate water tank → pure water pump → coarse mixed bed → fine mixed bed → ultraviolet sterilizer → precision filter → water object (≥15MΩ.CM) (traditional process).

(2) The technological process of pure water equipment is:

1. Adopt ion exchange method

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

2. Adopt two-stage reverse osmosis method

Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → first-stage reverse osmosis → PH adjustment → intermediate water tank → second-stage reverse osmosis (the surface of the reverse osmosis membrane is positively charged) → Purified water tank → pure water pump → microporous filter → water point

3. Adopt EDI method

Raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → primary reverse osmosis machine → intermediate water tank → intermediate water pump → EDI system → microporous filter → water point
