View Full Version : strong anion DI resin product question

08/27/2014, 06:28 PM
I want to setup something for dealing with high CO2 in my well water. I know the best way is to purge with air prior to the DI stages, but I am planning on adding a strong anion cartridge prior to my mixed bed DI resin cartridges. I will regen the strong anion resin myself (I've done mixed bed regen and it works fine for me, but separating the resin is a pain).

So my question: I don't see a pre-filled strong anion 10" cartridge? Unless it's the "silica free DI cartridge"?

The silicafree is a color indicating anion cartridge. We also have semi-conductor grade non-indicating anion as well. Call JR tomorrow if you want the semiconductor grade instead. The part number is DI-SF-10. Also ask him for two of our refillable DI cartridges. They are very good, and do not have the thick pad that are in conventional cartridges. They provide less of a pressure drop, in which, pressure drop hurts your membranes performance in rejection and production.

That would be the one.

Thanks for the super quick (after hours even) replies! Certainly reaffirms my decision to switch all my BRS filters to yours (very excited about your 99% rejection RO membrane).
