How to lower TDS and improve water quality
- Thread starter Mark...

Mark, don't count your chickens before the well is dug! Depends on the aquifer you're cutting into, because many Jersey aquifers are high in CO2, which will eat through DI resin within a day. Just hope you're not tapping one of those aquifers. If you are, there are fixes.
My old well was only about 50 ft and full of iron. I always bubble my ro water a week before running it though the DI. The new well is down 285 feet. Supposedly really nice water.
If you hit the same same water as me, you'll be fine. My well is almost 150ft and I have 50tds out the ground and no co2 issues.
They went 285, I'm hoping it solves my iron problems. They are still working on it. Major pain in the butt...
Edit: Just tested my iron and its gone from over 5 to 0.3...so far so good.
Wow. That a big improvement. When I first moved in I had my well completely serviced. It was pretty impressive when they fire high pressure water down the well head. I have a smaller version of old faithful in my backyard.

Making first RO and DI water since the new well. After making a fresh 25 gallons through the RO system, my TDS is 3. Before my TDS was 14 after bubbling for a week. Never has a TDS number for previously fresh RO water, but it must of been much higher than 14. My DI was do for replacing before the new well, but it is handling the TDS of 3 very well right now. I imagine the CO2 is decreased to nothing with the new well. Also iron is now 0 and ph 7.6
So all's well that ends well...

I think it is way down. Bubbling use to drop the tds a lot. Now without bubbling its only 3. When these batched are done, I'm going to bubble for a week and see if the tds of 3 drops.
Hows the tank? I have to see it.
Good news mark.

Mark, I'm not sure why your TDS is dropping over time with bubbling. CO2 has an insignificant effect on TDS.....considerably less than 1 %. That is, you can't use TDS to measure CO2.

By chance did you measure pH of the water pre and post bubbling. That would be a better indication of CO2 leaving the water.
I'll continue to scratch my head why the TDS would drop after bubbling....but it's not from CO2.
And congrats on a new and better well....that's the great news here. Dance

Ph was very acidiotic prior to the new well. In fact I had a tank on the system to raise the Ph. New well is a much improved 7.6 without treatment. Just glad the water is better.
pH of 7.6 without treatment....you have virtually no CO2 in that water. I'd now run that RO directly through the DI, eliminating the bubble step. That should make water production easier.
Yes, I did that yesterday....worked out great.
