We are using DM water in process. The DM water rinse stores in 60 KL tank.
after some time we get off smell in water, which is not in fresh DM water?

It may be an odor due to amines that are coming from the anion resin. This is common on new anion resins, and on resins that have been idle for a long time and then put into service. It is most commonly associated with Strong Base Type I resins with trimethyl amine functional groups.
