Chloramine and Membranes

[GoVols]

Yup that they will I never said they would not, I am just saying that they do not physically remove Chloramine they break the bond between the Chlorine and Ammonia and absorb the now free Chlorine and the Ammonia is allowed to move on to the DI resin where it will be removed.

Thank You,

Duly Noted :)

With ro/di you must worry about sediment filter getting clogged

Not really at all. When the working pressure on your guage drops below its normal reading it a signal the filter is beginning to clog up.

carbon lifespan or cloramines and chlorine will destroy the membrane

Even if the carbon reaches it adsorption capacity it still reduces chlorine/chlorine to harmless chlorides through electron exchange.
And in regards to DOCs - "Organics are rarely an issue on municipal water " (Russ Buckeye Hydro)

then a full deion resin bed can release ammonia iirc.

You measure TDS both at the RO outlet, & at the DI outlet. If the DI is no longer reducing TDS then its replaced. Same with the RO membrane.
