RODI, well water, insane DI consumption

[Feet4Fish]

Recently moved and now on well. Have well filter. Incoming TDS is 11, but burned through a whole canister of DI resin mixed bed in only 50 gallons!!! Have went out a well water test, but results pending. Any have a thought of the likely cause???

Most Likely culprit is co2 in the water. You can run the ro into a bin, toss a bubbler in it for a few days, then pump the water through the di to resolve the issue. Assuming co2 is the problem

What is your "well filter?" A sediment filter? Backwashing carbon tank?

A little more work but you may want to degas the RO water first. I started doing this and can get 400 gallons from my DI now.

I have the same issue. I never confirmed it’s CO2. I just deal with it.

I do however have 3 stages of DI though: cation, anion, then mixed. I can usually get about 80-100 gallons or so for each anion canister. The other two last a long time as long as I swap out the anion before it is all used up.

My water supply is high in CO2 so I run thru a degassing chamber then cation, anion, then mixed. I am getting about 2000 gallons from the anion now prior it was around 100.

Goes through a Springwell “well filter “ then a spin down, next a sediment then to the RODI

Can I ask how your degassing chamber is set up?

Flows into a vertical piece of 4” pvc with an air stone then it over flows into a 5 gallon container with a pump to pump thru the DI

If your incoming water is 11 ppm TDS (I’m assuming units since you didn’t say, what does it look like if you use only the RO and skip DI? My well water drops from something like 300 ppm at the well to 1-3 ppm after filters and RO. I don’t bother with DI since by the time I filter and then mix in salt the CO2 will be gone. I think people get any too obsessed with trying to get to zero ppm.

I was contemplating the same thing. The highest I have seen it go after the membrane is 2 ppm.

I split my RO and Di unit. I have a 34 gallon rubbermade collecting the RO water first. I then let it degas with a large airstone ( 8PPM water) overnight. I use a RO booster to pass the degas water in to the DI part. A little more work, but went from spending about 500$ in BRS Di resin per year to around 100$.

So I may have a CO2 issue as well, how do you test for it? My well water is crazy hard (1300ppm). Goes through a softener, and then RO gets it down to about 9ppm. Then, a BRS three stage DI system (cation, anion, mixed bed). The anion resin gets depleted after about 150 gallons, while the cation and mixed bed last much much longer. Or is this just normal?

ATI test on the RO water only showed silicon.

I installed an injection nozzle on my well to eliminate sulphur gas and I believe it also eliminated the CO2 issue associated with wells.It essentially ties in after the pressure tank and sprays
into the to your well casing,it degasses sulphur and I believe c02,I do not burn though di resin.If you use mixed bed color changing resin it's lifespan will be way less.I use non color changing and just change when tds raises above zero,I use only about 20 gallons of ro/di a week and my resin lasts about 6 months.
I also run my waste line back into my well casing so don't waste any water.
Icp always shows zero across the board.I also use a booster pump, essential imo as system pressure will drop too low for your rodi to be efficient before your well pump cycles back on to recharge pressure,I set my well pump to 60/40psi
