Does RODI filtration remove chlorine/chloramine?

[Malcontent]

guess I will be adding two more cartridges to my already 8 filter cartridge rodi. Will add then after the sediment filter and before the membrane.. any suggestions..send them to me...
Now I know why I was burning through resins so quick, Chloramine causing it ..Thanks for the info..
1. sediment
2 carbon
3 coconut carbon
4 rodi membrane
5 cation resin
6 anion resin
7 mixed resin
8 silicate buster.

I have lower than typical chloramine at 1-1.3 mg/L yet 2 carbon stages required me to replace them annoyingly often so I added a 3rd. Then I added a booster pump and added two more carbon stages. Bulk loose carbon (Calgon Centaur) by the cubic foot is the most economical. I like to put a sediment filter or carbon block behind them to catch the charcoal fines though.

I’m sorry, but that conclusion about burning through di cartridges with chloramine makes no sense. Chloramine getting through an ro is largely uncharged, and even if somehow it got thorough as chloramine and then somehow broke apart into chlorine and ammonia, we are only talking about 1-3 ppm of tds to bind to the di. Most folks have more than that getting to their di, regardless of chloramine or not.
