Consumables

Ions will remain in the water

Potential recontamination of purified water and reduced flow rates

Chlorine, chloarmine and organics remain, increasing the burden on downstream consumables which will need more frequent and expensive changes

High levels of organics and inorganics remain in the water reducing the functional life of the DI pack

Increase in airborne contaminants and potential recontamination of purified water
