Anyone tried re-generating their spent resin instead of binning it?

[SeanK]

Couldn't see it being cost effective plus some of the chemicals needed aren't the type of chemicals you would want
around your home the same goes for the waste leftover.
Not worth the hassle in my opinion.

[slap bash]

I do it all the time you need sulfuric acid or hydrochloric acid ( builders use to clean cent of brick work) and caustic soda. I save all my spent resin and do a 5 liter at a time maybe twice a year. I use a large water bottle which I cut the base off and added a tap to the bottle top which fits in a stand spout down.

So many on here are buying recharged resin on this forum without even realizing that`s what they are paying hard cash for. Businesses will not tell you this as it makes them money, keep they dumb and exploit there ignorance.

[slap bash]

Some time Sean K you don`t know what you are talking about. The water over after recharging will be less harmless the than di water as it is only salty water and can go down any drain. I have tasted it and I am still alive to tell the difference. Believe me I do my homework and research it a lot befor I do thing like this.

The caustic and acid is neutralised when mixed together.   If anyone is thinking of doing it then its much easier and less hassle to keep your resin separate instead of mixed bed.  That way you are eliminating the separation process before your regenerate it.

[Peter Fogwill]

Seemingly self regenerated resin last longer than bought mixed bed, as its not deteriorating in the bag before use.

How do you figure that out Peter do you regenerate di resin yourself?

[Peter Fogwill]

Have done in the past smurf.  All it needs is traces of the chemicals on say the cation resin to be left and as soon as it touches a grain of the anion resin it will discharge it.  Its easier selling and using mixed bed but its open to more problems. 

[slap bash]

Thanks Peter for that imfo as to keep the cationic and anionic separate. This would explain why so many are having problems with resin. It`s probably been store to long and badly with slow sales. I have considered using them in separate vessels for my di.
For Seam K if you mix acid and caustic together in equal strengths and parts  you will  produce salts the type will depend on the nature of the acid and lime in the water. 
It happens so often on this forum when a nugget of knowledge is shared it`s killed by misinformed opinions not facts. I mean this in the best possible way.
Before I write something I do a lot of research, which I find  interesting. Cleaning glass is a very boring thing so finding out how things work attract my interest and keeps  me interested .

What's the "Solo system" then slap bash!

[Peter Fogwill]

Yes slap bash was thinking that myself.  Not rinsed properly I expect or stored too long before sale.  Another possibility could be the fact that one of the mixed bed can't rember if its the cation or not but is more expensive than the other, and the mix might not be equal with more of the cheaper one.

Biggest drawback I can see is the rinsing out of the chemicals. How thoroughly do you rinse out the caustic soda? I would imagine any residue left in the resin will react with the Acid to produce salt water which will be absorbed by the resin so it will already be somewhat discharged. But probably cheaper than new resin but I expect it not to last as long as new.

[Peter Fogwill]

Rinsed very thourghly  both resin.  Very cheap to do as you can use the acid and caustic over and over again.  And can last longer than shop bought resin for the reasons you just mentioned, and what I stayed above. 

[johnny bravo]

our lass would kill me if i started to do this.

[Gerald Ash]

This is all very interesting and I can see the logic in keeping the two types of resin separate but can you buy it separately in the first place?

[Peter Fogwill]

Yes you can buy them separatly.  Don't know if it would be cost effective though if it was longevity you were after. And if it was to regenerate you would be as well starting off with mixed bed and separating it, and then keeping it separate.

Doesn't quite add up unfortunately 5 litre x 2 times a year  = 10 litres  less than half a bag = less than £40 hardly £200 pound per year saving.

He said 5 litres at a time which to me means 5 litre batches. He could do 10 batches twice a year. You're being pedantic.

[Peter Fogwill]

It could be set up in a garage out the way and in such a way that you don't even have to touch the chemicals.  It could mean the difference in using DI only and all the advantages of that.  They use atomated plants in industries that use a lot of DI water, all we need is someone to design a small one for window cleaners.  It could be as simple as disconnecting a couple of hoses, reconnecting a couple of hoses, throwing a couple of switches and the jobs done.
