Recharge di resin

[rhody605]

I have been looking at recharging my own di resin. Here is an artical I came across.

http://reefkeeping.com/issues/2008-09/nftt/

I have about 10 pounds worth of resin. Some used some been recharged by someone else. Worth a try I'm thinking.

I would keep the two resin types separated after the process.

Let me know what people think about it.

pretty sure its hydrochloric acid and caustic soda


availible at your local rona (hydrochloric acid = muriatic acid) which is used for controlling ph in pools and cleaning concrete etc and caustic soda aka lye is also easy to get locally

So far I have found muriatic acid at rona. 4L for $15

And Lye crystals (sodium hydroxide) at home hardware 3KG for $24.

Everything else is just containers and such.

the article says the acid wash is optional but i'd probably do it as well. make sure the stuff is working as close to new as possible.

what were the lye crystals sold as? do you have a picture of the container?

This is what I found. I have not tried purchasing it yet though.

remember it calls for high quality HCL or recharging exchangers, buy cheep stuff and don't expect the best job.

most stuff you can get at the hardware store is very diluted also.

Good call to check the concentration. Will have to see what % that one is. I was doing some reading and I guess a standard concentration is 32%. After that its an industrial strength and is harder to find.

most stuff you'll find at the hardware store is under 10% and the pool ones at HD and such are 14%. most places don't carry stronger stuff anymore.

doing this now you got buckets of hazardous chemicals to store or disposal of
