Treating High TDS

[Water Pro]

I've run into another application with extreme TDS. 2100 to be exact. They currently have a 2cf softener to treat 117 hardness. They also have 6ppm iron. I'm treating the iron with cl injection/retention. The existing treated water is a surprising 5gpg the evening before regen. They don't want to afford a whole house RO.
My question is, what do you think about using anion resin to remove the cl- from the na+cl- using anion, the allow the softener to only remove the na+. As it is now, I imagine excess Cl- ions are entering their drinking supply after the softener.
Thoughts?

Using an anion resin will typically result in no TDS change. We use anion resin to target specific contaminants and replace them with chloride. This will tend to dealkalize the water as well. Common contaminant reduction includes sulfates, nitrates, tannins, etc, which will be replaced with chloride so no reduction in TDS. If they want to reduce TDS, RO or similar technology...
