Recycling of water after Ion Exchanger Backwash
(OP)
We are trying to reduce our plants consumption of water. I am planning to recover the water discharge from a Cation exchanger when its regenerating. Is this ok? Any contamination it might bring?

GarySCWSVI has present the options for saving water with the DI equipment. Have you thought about RO in front of the DI?

At risk of sounding obvoius, audit the demin plant (or softener, whatever it is) to understand it better first (eg: quality of each waste stream as regeneration progresses .. online conductivity data would provide insight). Make sure the demin plant is 'tuned up' (using the right amount of water and regenerants (NaCl or H2SO4?) in the first place, etc). Gary has certainly identified good opportunity ... commonly practiced where water is highly valued, so it is proven good opportunity at that!
Sounds worth pursuing. Good luck.

Does this make any sense in terms of the safety of water, ie. drinking it?
Thank you.

If you want to recover the water and do not have rinse recycle, send it to a cooling tower or some other water consumer on the site.
