Regen Di Resin - Thread Split From Reefsupplies Thread.

[Neopimp]

===================
THREAD SPLIT FROM DISCUSSION ABOUT SHORT DI RESIN RUNS
++++++++++++++++++



-- ALL resin changes color whether it from blue to brown... or brown to gold brown ... they all exhibit a slight change/shift in color.
-- The color change will happen from top to bottom or bottom to top depending on your flow
-- Resins are pretty tough and can last for decades if you decide to regenerate them yourself. Iron is a poison to the Cation(i think) resin but not to the extent it seems to be reported here.
-- The chances of a bad "batch" is pretty low due to the manufacturing process itself.
-- If you are not getting color change and suffering breakthrough early then you are getting channelling through the resin cartridge.... path of least resistance etc etc. They need to be packed evenly to avoid it.
-- They will exhaust much faster if the preceding filters are leaking by.
-- Hard water will deplete them faster as well.


Typically Anyways


I'd like to trial some the "bad" resin if anyone is around the sarnia area.

some valuable info there @Neopimp
you can regenerate DI resin??? I know how to regen phos and nitrate remover but..... I have never heard that before.
whats the basics to that and are the results worth the effort?

Regenerating requires a nice outdoors afternoon, Strong Acid... Strong Base... Bunch of containers... Safety gear, and enough resin to make it worth while.


1. Place all used resin in a bucket.
2. Bubble air through resin for a while, this will seperate the Cation from the Anion resin (One is more dense so one will stay at the bottom and one will move to the top)
3. Remove the Cation resin from the Anion Resin.
4. Soak Cation resin in a diluted strong acid (Might be muriatic??? have to check). Drain. Repeat. Rinse couepl times with water
5. Soak Anion in diluted Base (Lye ? or Caustic Soda?) Darin Repeat, rinse a couple times .
6. Mix the resins back together and rinse again.

Done.

now if you had a 5 gallon pail of the stuff that woudl be enough to last a coupel years... I keep my used stuff.


You could regen your resins dozens of times and still have a good run until it breaks through again. Each regen does take a little life from the resin though.

At work we have A DI train... 20ft tall Cation exchanger 20 ft tall Anion exchanger and then a Mixed Bed (which is what our DI stuff is). We regen them every couple days and the life on them is almost a decade. We get ~2600 tonnes of water before the trains break through and conductivity starts to rise. typical conductivity is .1uS.



For everyone..... 1TDS or uS water is still damn clean water.

Sh!t, Iv'e been tossing it.

I think everyone should save their DI resin and I will hold a DI Regen Kegger this summer

Is there a way I can like this more than once?

hmmmm ok. so I should save all my DI resin for a nice summer day?
just LMK when you would like to come over @Neopimp to guide me through the first attempt. BEER and BBQ will be provided. LOL

haha.. dont think

count me in!

 

[Neopimp]

here is one way to do it.

I do not think its worth it until you have more than a what he is doing. And I do not htink that his mixtures are what i have used.

 

[zoomster]

Splitting this off was a great idea!

A purolite dealer when first talking with him, and him not totally understanding my process and application suggested something like this for my own home. Not QUITE as big but basically said you can run straight resin, not even RO through it. That you can even rent the units from water places. From there he went on to explain regeneration. They will do it for me if I wanted. $80 bucks, but that's with a MIN. of 7 cuft. For those not sure that would be over $250 canister refills.

HAHA start collecting... we deal with purolite for our stuff at work. .. 7 cu ft ... better start saving or just buy 20 bucks in chemicals and a case of beer.

Can it be dried, I assume centrifugal force would work.

 

[Neopimp]

drying out resins are not good for them... they will crack as the moisture is pulled out... keep them in a zip lock bag
