Input water quality standards
In order to make sure the best treatment of the EDI System, It’s better the input water quality meets the below table :
| Raw Water | Output of RO System, the Conductivity ≤ 10 μ/ cm |
| PH value | 6.5—7.5 |
| Temperature | 5℃–38℃ |
| Working Pressure | 0.15—0.4MPa |
| Hardness | ≤1ppm(Take CaCO 3 as sample test) |
| organic matter | TOC <0.5ppm,it’s better none |
| Oxidant | active chlorine(Cl 2 )< 0.05ppm;
ozone(O 3 )< 0.02ppm |
| Heavy metals | ions < 0.01ppm (including Fe, Mn) |
| Silicon | < 0.5ppm(by SiO 2 ) |
| CO 2 | CO 2 < 3ppm, if the CO 2 > 3ppm , you can use
NaOH adjust the PH value |
| Particle | ≤1μ m |
