Vacuum coating cleaning wastewater treatment system

1、 Pretreatment system → reverse osmosis system → intermediate water tank → coarse mixing bed → fine mixing bed → pure water tank → pure water pump → ultraviolet sterilizer → polishing mixed bed → precision filter → water object (≥ 18m Ω.Cm) (traditional process)

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 μ M precision filter → water object (≥ 18m Ω.Cm) (new process)

3、 Pretreatment → primary reverse osmosis → dosing machine (pH adjustment) → intermediate water tank → secondary reverse osmosis (positive charge reverse osmosis membrane) → pure water tank → pure water pump → EDI device → ultraviolet sterilizer → 0.2 or 0.5 μ M precision filter → water object (≥ 17m Ω.Cm) (new process)

4、 Pretreatment → reverse osmosis → intermediate water tank → water pump → EDI device → pure water tank → pure water pump → ultraviolet sterilizer → 0.2 or 0.5 μ M precision filter → water object (≥ 15m Ω.Cm) (new process)

5、 Pretreatment system → reverse osmosis system → intermediate water tank → pure water pump → coarse mixing bed → fine mixing bed → ultraviolet sterilizer → precision filter → water object (≥ 15m Ω.Cm) (traditional process)
