How to recharge DI resin

I do not consider myself a chemist, as for the lye and water mixing I did follow the TWP directions. I did not find any splattering issues when I added the lye to the water. I was watching for it but nothing really happened in my containers.
I also added the lye to the muriatic acid with no issues there. This may be due to the additional water used to rinse the resin.
So if I did the process backward from the post above there must be a margin of safety from mixing water with the chemicals, than directly out of the containers they are sold in.
Thanks for the complements

im doing this at work using two di chambers ( we go throu one di tower a week so we went with two different resin ( on kati one ani)
all that we do is hold a bucket up and run the wateracid and water/lye throu the chambers ( one to kati one to ani) and thats it.. dont even bother taking them out of hte ro unit
 
FYI to people reading this post, this is a really great way to run a DI only system and not waste all the water using a RO. This saves me a ton of water, if water usage is an issue for you. You can also make 100 gal of clean water in about an hour with 0 waste water.
 
I have 410 tds coming into my home from the city water system. Last year I saw 525 tds. I would be lucky to get 1 week of usage of my di resin before I had to recharge. Recharging is a good thing but doing it as a weekly core does not sound like fun.
I have read some of the information on di filtering and the water saving sounds good. The concept is interesting but not for Wichita, KS.
 
It is also not sufficient for removal of all substances. DI only can be used, but suitability is highly dependent on. the input water.
 
Bean - While I usually am in agreement with you, i disagree with your angle on hybrids.

It's more a matter of WHAT pollutant we are trying to avoid. Hybrids can drastically reduce CO2 emissions and could potentially reduce the US dependence on middle eastern oil. For me, that is a good thing.
 
If you want to debate hybrid cars and their environmental impact, the Lounge is the best place for that. No need to discuss that here. I want to learn about recharging DI resin. :)
 
I would agree with the oil part... but I think the whole C02 thing is laughable. Carbon offsets anybody :) Did I mention I planted 25,000 harddwood trees this spring... Where do I apply for my offsets?

As for the resin... Yes it does stick to everything. With some planning (as mentioned above) the recharge can be done in the canisters without every removing the resin. A local refer does just that for his greenhouse system.

MrSpiffy... relax :) we can certainly stay on topic and all learn (discuss) something tangent at the same time.
 
By all means, discuss! :) I just don't want any whining, bickering, or petty verbal slapping like little kids. (Can you picture that? Some threads certainly make me picture that!) It's amazing how quickly that can happen, sometimes.

With such touchy topics like global warming and environment (I lump these topics in with firestarters like religion and politics. :rolleyes: ), I just want to make sure we don't start a flamewar for no reason. It would be odd to argue over the environmental impact of lead/acid or NiMH batteries and hybrid cars, when the discussion started with recharging DI resin.

I didn't mean to interrupt! Sorry. :)
 
Back to the main topic, I have talked to a friend and he is giving me enough resin to do a photo shoot. I will be posting as soon as the recharge is done.
 
very cool. I have a bucket full of used DI-- and it just so happens my time is cheap!!

bean- if you think hybrids are an environmental joke, have you ever looked at how the bulk of hydrogen for "environmentally friendly" fuel cells is made???
 
Sweet! I'd love to see a photo shoot!

Isn't hydrogen produced using electricity to separate water into hydrogen and oxygen? That electricity's gotta come from somewhere. (i.e. coal-burning power plants..?)
 
A common misconception. most is produced by splitting hydrogen off of hydrocarbons (like coal) at high temps (like 1000*C), consuming energy and releasing a lot of carbon monoxide and other nasties.
Electrolysis is just too inefficient to be commercially viable right now.
 
Well, in either case, it's still not exactly "environmentally friendly", if you ask me... You still need all that heat from somewhere, which requires burning fuels.
 
... now if we put a rechargable di at the end of your cars tail pipe.....

no really


are you recharging both resins in the same thing or are you seperating htem first.

because i dont think you can recharge both together you have to seperate them

to seperate the DI resins i found the easiest way is to hire an illigal imigrant to sort each bead one by one...
no really.
if dump them iin to a brine solution when they settle one type will be on top of the other ( then jsut siphone out) ahrd to do if you dont have much di ( and your going to get some of the lower layer when you suck off the upper layer no matter what you do) only makes sense when doing in large quanities

now sadly i forget what ones float and what ones sink
 
oh i see you did talk about it.
but apparently a heavy brine solution makes it easier to seperate..
try it next time and let us know..
( since i dont intend to do it this way ever again)
 
The all of the di resin starts in a lye bath. Then the cition resin sinks. A gap is formed that separates the anion resin from the cition. With a baster the top layer is removed and put in another container. The cition resin is then rinsed and drained; it then is put back into its container. The acid is then added to the cition. Both cition and anion resins then sit for about an hour. They are then rinsed and combined.
I will be doing this again tomorrow. I do not see how a heavier lye solution will make any difference, the resins separate very nicely.

A.T.T.R. Have you done this before?
 
I'm running a DI Kati/Ani system since I'm on a well and don't want to waste water with an RO membrane (nor do I wish to monkey with putting said wastewater in my washing machine, garden, etc.).

My incoming TDS is over 400. My only regret is not having more resin, since I have to recharge quite often. It's pretty simple, however, since my cation and anion are in separate chambers. I may DIY additional chambers from 4" PVC and the Spectrapure bulk resins.

Regardless, I can get 0 TDS water without wasting a drop. That is what is important to me.
