1. Pre-treatment 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 process)
2. Pre-treatment → reverse osmosis → intermediate water tank → water pump → EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polished Mixed bed → 0.2 or 0.5μm precision filter → water object (≥18MΩ.CM) (the latest process)
3. Pre-treatment → first-stage reverse osmosis → dosing machine (PH adjustment) → intermediate water tank → second-stage reverse osmosis (positively charged reverse osmosis membranes) → purified water tank → pure water pump → EDI device → ultraviolet sterilizer → 0.2 or 0.5μm precision filter → water object (≥17MΩ.CM) 17MΩ.CM) (the latest process)
4. Pre-treatment → reverse osmosis → intermediate tank → water pump → EDI device → pure water tank → pure water pump → ultraviolet sterilizer → 0.2 or 0.5 μm precision filter → water objects (≥ 15MΩ.CM) (the latest process)
5. Pre-treatment 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).
