Separating mixed bed Di resins

[JoJo]

Brad,

I just got a used TWP from Christy. Once I have enough spent cartridges, I plan to separate the resins,"lol" I planned to take several emptied cartridges and modify them into a 3 column TWP (carbon,cation,anion). Is this possible or do I have buy 2 additional base units. My plan is to fill 1 cartridge, fill with carbon and install it to the base unit. Take 2 emptied ones , cap them at each end and install i/p and o/p fittings , fill 1 with cation the other with anion and run them daisey chain to the o/p of the base unit "carbon". Will this work? Any suggestions? Thanks!
