Ro/Di anion media

[rlman41299]

Hello I have a spectrapure maxcap 180gpd system and hoping that someone can enlighten me with my question. The system has 4 canisters and I added an additional canister for a mix bed resin. Now the last the 2 canisters are filled with cation DI and anion DI canister respectively. So my system is basically water in, sediment filter, carbon block, 2 membrane, cation resin, anion resin then last is the mixed bed resin.
Now my question is, I am using 3-4 times as much anion resin compared to the cation and mixed bed resins. The last time I replaced the anion resin the output tds reading on this canister was 2 tds and I have another product water monitor after the mixed bed resin which was also reading 3 tds. Now I know that my mixed bed is not exhausted since it has not changed color yet. But as soon as I replaced the anion resin with a new new one the TDS from the mixed bed out put changed to 0 tds.
Also why would I be using 2-3 times more of the anion resin compared to the other 2. My water is being fed from a water softener with a huge activated carbon tank before the water softener so chlorine is no longer in question since I am sure the activated carbon removes it.
Anyone care to explain further? Thank you.

Are you on a well? if so, that is it 100% CO2 from well water exhausts anoin very quickly, I run 3 anion canisters after my 1 cation, and before my mixed bed. when anion 1 exhausts, i move #2 the #1 posion, #3 to #2 then new one to #3 position. Keeps water at zero, but spending a lot of money on anion. Been trying to figure out a way to gas off well water before RODI ..... Hope this helps.

If your going through more anion that just means your feed water is high is negatively charged molecules.

Your water softener would be removing cations or positively charged moleculesz and dumping sodium (an anion) into your water

So basically your feeding your system with the cations largely removed and dumping in more anions for removal.

thank you both for the reply. S end question is. Do I need to do anything to make it better? or my system is fine?

As for a well water? I don't know. all I know is it is fed by the city.

Sometimes neighborhoods are fed by a community well, not a water treatment plant. Find your exact water source then I can try to help from there. let me know !!

I checked our map and it says "ground water". I assume that is well water?

YEP........ Community Well water.
I'm trying to figure out a degassing method for my personal well. I have not come up with a solution yet, but going to incorporate a few of my engineer friends to try and come up with a solution.

The east way is to let it sit with a bubbler, then return and pump it through DI after it off gasses. But that's not the most practical.

DIY CO2 Degassing Chamber for RO/DI

Well, I learned the hard way that the water coming out of my well has a high CO2 content. I burned through a pound of DI resin and only got 40 gallons out of it.... To keep this from happening again, I could either buy lots of RO/DI water or remove the CO2 from the RO water before I pass it...

If this was for sale and it could easily handle making 100 gallons of RODI per day, I would buy it.

I blow through anion way faster than anything else. I believe it's from high silica in my water. Also I think the mixed bed resin can be depleted without changing color. Like if it's really old. Something to keep in mind
