View Full Version : How to regenerate "KENT Mixed Bed Resin Cartridge"?

October 28th 03, 09:44 PM
I am talking about KENT deionization stage of multistage RO filter.
Is there a way to regenerate its functions to the original level
by treating with chloride acid (or other solution) or the only way
is to buy the new catridge and replace old one with it?
It is not very expensive, but throwing this away seems like a big
waste and Mother Nature will hate me for not seeking other options ;-)

I have heard you can do this Muratic acid, but do not recall the procedure.
You should be able to find a generic procedure by searching on altavista.
My concern would be that you could not get the ends to fit tightly and there
would be resin in your final water. Also, what were you going to do with
the stuff below the floss filter? Is that just carbon?

I've never tried to "regenerate" a DI filter resin. what I have read is
that the chemicals required to do it (and I don't recall what they are at
the moment, I'm sure Boomer will though) are very dangerous to skin and
lungs. doesn't seam worth it to me.

Yes & No but don't bother....... as it is a "Mixed bed" and you would have to separate all
the different resins and threat each one with x, y or z solution. You would also have to
know what resins they are and I'm sure Kent will not tell you. Kent's Mixed Bed DI's are
suppose to be disposed of once exhausted

Thanks. I have found on the KENT website they make separate cationic/anionic resins
and market them as "rechargable". I guess since I have exchausted my mixed bed anyway
I could buy one cartridge with first kind and the whole new module (canister+resin)
for the second kind. Then, after both connected serially will exchaust I could try
to regenerate them. Have you seen these resins in any stores? I cannot find them...
I have to write to KENT for this info maybe.

Yes, one of them is 5% HCl, but when you regenerate your resin
you do not drink nor inhale the stuff... ;-)

I was planing to put the regeneration fluid in the bucket
and then pour resin balls in it. After a minute or two
I would repeat with fresh fluid and put it back to the cartridge.
Of course my imagination faced reality could be the problem here...
I have no idea if these cartridges are easy to open/close.
Never done it before... :-)

I have found the info on their website http://www.kentmarine.com/MAXRpg2.pdf
Looks like their MAXXIMA-R filter has two regenerable resin cartridges.
They even describe the regeneration process in the document pointed above.
Now, when I know the name of the filter it is used in it should be easier
to get this regenerable resin in stores. Thanks everyone for their input.
p.s. Is there a way to test if the carbon prefilter is still good or need replacement?
This is again a part of my filter which I am told to replace every 6 months, but I am
not sure what is more importand: how much dirty water passes trough it or the time
is was first wet. In my case the filter is not used too much, I am making about 10
gallons a week, so I would expect this carbon prefilter to last much longer than 6 months.

When to chang the prefilter is depend on your water where you live. The
general way is to use a TDS to see how efficient your RO [DI] is doing. You
also can tell by the pressure gauge on your RO [if equiped].
Remove the DI if you have one and just measure RO only and read the reading
of your TDS. If it reading like say about 10ppm or so, you can try changing
the prefilter and see if produce better result. If you have like 3- 5ppm, I
would say it ok. You do not want your DI to take on extra load of work due
to prefilter or carbon block.
Note:
For general use, 10ppm would be ok for yourself but I would change if it go
upto 5ppm and the DI will bring it down to near zero. Also check your carbon
block if prefilter is not the cause.

Test your water for chlorine. If anything more that 0 appears, it is time to replace them.

How the carbon prefilter influences amount of TDS after RO filter?

I have pressure gauge - what is the method you are talking about?

I have only one stage prefilter in front of my TFC membrane.
I was told it is activated carbon but since the cartridge
cannot be opened I am not really sure what is inside...

Thanks for the link. Have you done it before with this recipe?
What is thi secret way to separate resins? Is it just water? ;-)
From the description I am taking that anion and cation resins
differ in specific weigt, so they will separate when water will
flow up way the column... Am I guessing it right?
And one more thing - acording to some sources mixedbed resins
work better in producing cleaner water than separated resins.
The article states the opposite. Which is true and why?

no. i don't use a di. i've heard no one, over the years, state that this was
either hard to do or didn't work. gary's been around these groups pitching
this for at least 5 years, if not longer, although i haven't seen too many
posts from him in the last couple of years.

yes. different weights will float one type.

i wouldn't know. i'd bet gary does. his page has his email address. i'd
suggest asking him.

When prefilter either get clog or have excess of sediment, some of it will
go thru the rest of thes stage. The final result will be higher TDS.

You can tell how efficient your RO is doing by the gauge. When you first
have your RO, it should be efficent and the gauge indicate higher pressure.
But as time go by, the prefilter lose it efficiency, it pressure will
decrease.

Sorry, I did not realize you have only two stage RO. I assumed you have
something like Marc have.
OT here or buddin'in.....
Why not use a 4 or 5 stage RO/DI setup? This way your DI will not depleted
too fast. The 1 to 4 stage will reduce as much as it can and DI will finish
the last stage. From that, your DI and membrane will last longer and do not
really need to change often. The last time I check, the DI and Membrane are
costly when compare to prefilter [sediment] / carbon block when time to
change it.
According the KENT DION 200R
http://www.petsolutions.com/cgi-bin/cgiitmls?m=ThisP&p=1024.150000&l=37
It just a DI unit with one prefilter that trying to do all the work / load
before DI. Then DI will finish the rest if any sediment pass thru the first
stage.
This is what I am seeing:
Prefilter > Cetiion Rasin > Anion Rasin.
I forgot to mention, when DI need to change by it color indication. I did
not realize this. All DI will need to change when their color change to
reddish-brown tone (?) regardless of original color which indicate
depletion. Typically it will begin changing color from the bottom up (I
think).

This is the second attempt since the first reply did not answer your
question regarding regenerate DI but to how or when you need to change your
DI.

I understand, the gauge is in front of the whole set?

In my case there is similar situation. Prefilter is actually sediment
filter (10u) and carbon filter in one. Then I have TFC RO membrane.
After that, I added DI based on mixed resin.
I am not sure how do I influence performance of the filter if I sort
resin into two separate parts: cation and anion resin and put them
in the separate canisters... Whould they work better mixed or separated?

Regarding DI refills, this local vendor sells DI resin and the clear refillable cartridge, for $20.
http://www.dallasmarine.com/RODI.asp?search=RODI
I believe it is the color-changing kind, but be sure to ask them.
