so the anion doesn't need to soak in acid? or did I miss something?

Ok so the Lye recharges the anion and the acid recharges the cation. thus creates the reaction needed remove the rest of the TDS after the RO membrane.

That last pat is more of a question. does the anion and cation create a chemical reaction when Ro water passes through it?
