Packing DI Resin

[RaymondL]

When replacing and refilling DI resin I'm wondering what the best method is to ensure uniform distribution in the canister.

1. Pour a bit and bang the canister on a surface after each pour.

2. Pour and use some sort of stamper thing to press down on the resin to compact it.

Would 2 cause problems with being too compact?

I do bang bang on the table, lol.
Either way as long as your not smashing it.

I have tried both ways and think tapping on table works better. I 3D printed a tool for packing which works good when the canister is not full but when it is towards the top i end up making a mess.

I’ve always filled up the canister and packed it down with the bottom of a beer bottle - the bottle fits perfectly into the canister. I do not think you need to worry about overpacking it within reason.

Ok folkes... are you sure you are doing the right thing? None of your methods will achieve results anywhere near my compaction method, which is:
- add resin
- pour some RO water on top of resin and SLIGHTLY shake the pod (no need to agressively bang it!) allowing water to slowly drain from the bottom of the pod
- repeat until no more resin can be added

Here's another free advice from Borat: as output TDS goes up over time, don't replace resin. Just open it and add some extra resin and use my compaction method. Most often TDS goes up not because not because resin has been depleted but because compaction has become imperfect and water created channels in resin.

What a fantastic idea!!! Never would have thought of that, so thanks for sharing. What you suggested makes sense - adding RO water and letting it drain will ensure that resin is 'packed'

Thank you!

I usally just use a bottle to compact it but I'm going to try @Borat method next time.

No... packing it too tightly is not a concern.
