Process description of laboratory ultrapure water equipment

The laboratory ultrapure water equipment is a set of high-end water production equipment dedicated to laboratory water. However, because different experiments have different requirements for water quality, the laboratory ultrapure water equipment has the preparation of different specifications of ultrapure water.

Laboratory ultrapure water equipment process

  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 → polishing 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)
