Rechargin a Kent Deionizer

[dmirza]

I have aKent deion 200R Deionizer. I want to re-charge the cartridges but I don't know how. I know it involves lye and Muratic acid, but I don't the exact process of recharging. Does anbyody know how to reacharge a deionizer?

Cation gets recharged with acid and anion gets the lye. I don't remember the amounts of each though. I'll check when I get home.

How many gallons are you getting out of that unit?

don't know how many gallons I get out of the unit. I haven't really been measuring it and I haven't kept it clean.

Do I soak the beads in muriatic acid/ lye or do I need to drip it?

How long does it need to spend in the acid/lye?

 

[CarlC]

If the resins are heavily contaminated I would soak them. Otherwise a nice slow drip will do the job.

When I have done my resins in the past I usually soak them. I find it easier than dripping. Altogether with the strength of chems I'm using it takes about an hour from start to finish.

do you have to dilute the chemicals at all?

 

[CarlC]

Oh ya! If you added them straight you'd probably melt the resins.

Ok here you go-

Mix 18 ounces water with 6 fluid ounces of Lye.
Mix 12 ounces of acid to 12 ounces of water. Add acid to water, NOT water to acid.

I mix these a day ahead of when I am going to do my recharge. I use old plastic milk jugs to store the mix's. When you mix the water and Lye it is going to get VERY hot. I have a 5g bucket of cold water handy to put the lye mix container in after I get done shaking it. You might have to shake the mix a few times since some of the lye will harden in the bottom of the container.

Like I said I prefer to soak my resins. I don't know if this mixture will produce enough if you plan on dripping it into the canisters.

thanks carl, that helps a lot.

i think you need to have the cation and anion separate from one another in order to recharge them separately in their respective solutions.

that's why i never did di resin recharge...it seemed like more pita than it was worth.

I have a kent deionizer, where the cation and anion are seperate.
