BRS bulk resin . Difference between Blue and Pro mixed bed

[chicago]

Quick question.. what is the difference between the mixed bed di resins as follows

1. Mixed Resin (blue one "recommended"). The one I usually get... stated on the site as
BULK DEIONIZATION RESIN (COLOR CHANGING)

vs.
2. Pro Mixed Resin
PRO SERIES MIXED BED DI RESIN (COLOR CHANGING)

The site states..
Mixed Bed Cation Resin (purple) - Most commonly used after single bed resins to polish any remaining contaminants. It contains both positive and negatively charged ions and will change from purple to amber as the cation resin is depleted. It is also perfect for single canister DI systems that have an excess of positively charged ions like calcium, magnesium, aluminum, ferrous and ferric iron.

Mixed Bed Anion Resin (blue) - The most commonly used resin in single or dual canister RODI systems and contains both negative and positively charged. The anion beads contain a blue color changing indicator that will turn to an amber color when it is exhausted. This resin is excellent for systems that have an excess of negatively charged ions that are not removed by the membrane, like phosphates, nitrates, sulfates, etc.

To be clear...They both CONTAIN AND MIX OF ANION AND CATION?
If they are both a mix.. I see one is used more for positively charged and the other for more negatively charged.. I did watch the videos but would like further clarification.

have total of 7 canisters.. 5 canisters available for resins..
was thinking.. cation>anion> mixed Purple bed (cation) > mixed Blue Bed (anion) > ?

BRS? Randy?

Thank you

I want to know too !

Good question I was looking at these options the other day.

I had the same question a couple weeks ago when I switch out my resins. I was surprised BRS didn’t have and explaintion if the difference in the product details. I also found it interesting that the Pro Mixed resin costs exactly the same as the bulk mixed bed.

The cation mixed-bed resin (purple) contains a color-chainging dye on the cation beads. The anion mixed-bed resin (blue, the "standard" resin) contains a color-changing dye on the anion beads.

If you do not have a single-bed setup, use the blue anion mixed-bed. In most tapwater, the anion resin will get depleted first. As a result, you want a color change on the anion resin (the blue beads) so that you can accurately tell when one of your resins is depleted. The cation mixed-bed is more designed for use as a final polish after two single beds (cation > anion> cation mixed-bed). This is because the most likely ions to still be present after the single cation and anion beds are ions that will deplete the cation resin more quickly. As a result, you want a color change on the cation resin to know when your cation mixed bed is depleted.

As a note there is no such thing as a cation mixed bed. Mixed be indicated that there is a combination of two or more types of resin beads. In this case the mixed is a combination of Anion and Cation exchange resin beads. BRS is now selling 5 different ion exchange resins. (1) Bulk Color changing DI (mixed bed anion and cation) (2) Bulk DI (non color changing mixed bed) (3) Pro Anion Exchange DI (color changing (4) Pro Cation Exchange DI (color changing) and (5) Pro Mixed Bed DI(color changing anion and cation). The question is, is there any difference between the bulk color changing (in which only the anion resin beads change color) and the pro mixed bed (in which both the anion and cation beads change color) other than the fact that the cation beads change color in the pro resin.

To me, if that is the only difference I don't see the advantage. As they have previously stated in their videos is it typical for the anion resin to reach it capacity first. In a mixed bed situation you would not want to continue using the resin once either one of the resins exhausted. So it wouldn't really matter if all of the blue beads changed color and you still have capacity left in the purple beads, you would change that resin out right away. Don't get me wrong I like the idea of the individual resin. Basically you aren't throwing out cation resin that still have life in it, but in a mixed bed situation I don't see the point.

Of course. The reason I categorized these resins as such is to avoid confusion. Both the OP and Bulk Reef Supply categorize the resins in the way I described. Perhaps you should email Bulk Reef Supply and ask them to correct their site descriptions:

If you're looking for "benefits" of using the pro vs the bulk, I don't think there are any. They're both specific tools and have specific applications. There's no "benefit" to using a hammer over a screwdriver, unless you're trying to drive in a nail. And vice versa with the screwdriver and a screw. If you only have mixed beds, stick with the bulk resin. If you have a single bed setup, get the pro mixed bed as a final polish. BRS might be able to clarify further, but so far, this is what their marketing and promotional materials have said.

If there are no differences between the Pro Mixed Bed and the Bulk Mixed Bed why would you sell both. You could just as easy use the "Pro" individual cation and anion resin and then follow them with the bulk if there are no differences other than the color changing.

Looking closer at the BRS description for the Pro Series mixed Bed be it does appear that the description is a little bit weird, in that is states that there is a mixed bed cation and mixed bed anion, and they only seem to sell a Pro Mixed cation (purple). Again, When talking about ion exchange resin, when you say mixed bed it indicates that there is a mixture of both anion and cation resin. It is possible that the Pro Mixed cation has a higher ratio of cation to anion beads, but the description doesn't state that. If this was the case you would want to use this in a situation where you ran individual resins in series and still have a larger amount of positively charge ions coming out prior to the mixed bed.
