DI resin

I changed out my color changing DI resin in one of the 2 canisters because about 1/3 of the cartridge to 1/2 was brown. I was also getting 5 tds coming out of the filter. My question is: Do I need to change out all the resin or just the brown/orange part? I changed the whole thing but I was thinking about if I am throwing away money when I don't save the DI resin that hasn't changed color. :confused:
 
My TDS doesent start to rise until probably 85-90% of my resin is brown. Considering you have 2 canisters of it, is it possible the inside container isnt seated properly? Maybe the seal at the top isnt completely setting and water is escaping without going through the resin. To me it just seems odd that even with that much resin left over your TDS is creeping up.
 
My resin usually gets half orange and then the other half is blue. Spectrapure said this is normal. I didn’t ask them about reusing the still blue resin.

Yeah I am not sure about the top seal on the canisters. I will look at it next time I go down stairs. I think I will also try to salvage some of the resin that is still blue next time. I don't think it could hurt anything to try it.

Since my incoming water is so high I have been toying with the idea lately of trying to recharge my resin. Have a small bucket of used going but haven't totally decided if I will or not. TDS lately has actually been down to Mid 300 incoming. Usually, especially in the summer, incoming runs 575 to 650

Start as I know it's actually two different types of resin. You could ask in one of the manufacturer forums.

? You are saying that there are 2 different kinds of resin in the BRS bag of DI resin?
 
So... is only one kind of the resin we get in our BRS resin color changing and therefore not all of it will change when it is depleted?

You have anion and cation resin. You can buy them seperate also. I am using two canisters filled with anion first. Then two with cation. I get 200g of zero tds till one can of anion is used up. Then I refill and switch canisters of anion. I have yet to change any cation. BTW I have 5-600 incoming water on well thru softener.

I haven't looked into this separation of the two resins before. Is it cheaper or more cost effective to run them like this in your opinion?

I guess it depends on your water situation. In mine it saves me money. I second the brs video recommendation.
 
There should be no reason to change your DI yet if half of it is still blue. I am guessing your membrane is bad, was was the last time it was replaced?

I have steady TDS over 300 in my house and I don't start getting anything over .000 until the resin is over 80-90% brown, the first .5 micron filter needs replacing or the membrane needs to be replacing.

I replaced all my resin in November and am still under 50% brown with a TDS .002 because my first filter needs replacing. To put that in perspective, I run about a 250 gallon system with about 3 1/2 gallons of evaporation a day.
 
Running separate Cation then Anion & last Mixed canisters

I thought the BRS DI video recommended to run 3 canisters after your RO unit, 1st with Cation, 2nd with Anion and last with Mixed bed? This was supposed to save media & expense. Did I misunderstand the video? Thanks

I don't know I will have to watch the video. I have an empty canister just hanging there on the wall so if this is the case I will have to look into hooking it up.

BRS VIDEO called "œDoes mixed bed DI resin really need to be mixed?". Check it out and let us know what you think.
