Double pass RO system with EDI system for hospital medical


This is 500LPH double pass RO system with EDI, apply in Pharmaceutical Industry.
It can be produce ultra pure water 15-18 MΩ.cm
Below is feed water quality request before EDI:
1.Inlet water :1.conductivity less than 10us/cm)
2.hardness ≤1ppm(by CaCO3) matter :TOC when <0.5ppm,can not be checked
4.heavy metal: ion< 0.01ppm Fe 、Mn 、transitional metals
5.silicon < 0.5ppm(by SiO2 )

In that case, the raw water should be treated by RO water treatment system.
