Chloride content in deionized water
Thread Content
Can reverse osmosis combined with a mixed-bed resin reduce the chloride content in deionized water to below 0.5PPM?
Sure, it’s fine to drop it to 0.
However, this depends on the quality of your water inlet and the service life of the membrane.
But I can’t do that; the chloride content is 5PPM, while the requirement for newly installed equipment is less than 0.5PPM! What should be done?

The carbon filter has a water conductivity of 0.238 ms/cm and a chloride concentration of 32.8 mg/L. The conductivity of the water coming out of the mixed-bed is 1.06 us/cm, with a chloride level of 2.8. Something seems wrong with these values.
Both mixed-bed and electrodialysis can meet your requirements. The analysis data you provided indicates that at least one of the values, either chloride or conductivity, is not reliable.
Primary desalination + mixed-bed treatment reduces the chloride ion concentration in the effluent to below 0.02 mg/L.
