Removing acetaldehyde from ethanol

Has anybody ever had to remediate a large volume of acetaldehyde contaminated 200proof ethanol?

I’ve read it can be distilled out due to large difference in boiling point.
I’ve heard it can be filtered out using AC
But the one that is interesting me is using ion exchange resin beads

Just wondering if anybody has tackled this one before. I have 11,000 liters I would like to not just dispose of.

Thanks

How did it get in there? I would still go for distillation

It occurs naturally over time. The totes are about 4 years old
