RE: RO and chlorine


For the water here in central Texas the carbon block pre filter on a RO unit
will break the bond between the chlorine and ammonia found in the
chloramine, but the feed water still has ammonia left in it and the RO
membrane can not remove the ammonia as its molecules are too small. The only
solutions are to treat with a ammonia converting chemical such as Prime or
Amaquel or keep a seeded bio filter in the storage tank. The waste water
will also have ammonia, but will be more toxic at the higher ph.

Does an RO unit remove chlorine and chloramins (sp?) from the RO unit? I
am assuming it does. But does it also remove chlorine and chloramins from
the "waste" water?
