Well Water Chewing through DI Resin

If you’re getting 90 psi as I think you said, that’s not a problem, at all

Don’t forget to change this while you’re at it

What is that called? I did not order a replacement for that.

Auto shut off valve

Auto shut off valve

As in a back flow valve or high pressure?

 

[BigJohnny]

The information. ~300tds out of the well, 25tds after RO membrane and 0 TDS after two canisters DI resin. Booster pump is getting pressure to 90PSI measured between membrane and resin.
System is the 150GPD.
Problem: I just replaced the tow stages of DI resin and after only making about 50 gallons mi Resin is already depleted halfway up the first canister. Also noticed it looks like it only used a partial of the first canister and started consuming the second canister as you can see from the pictures. This is older resin in the first that has been regenerated a few times so maybe it has lost its color changing ability and the stuff that did change right at the beginning was the new stuff. What are your thoughts on the rapid consumption? CO2?

You need new membranes

Hi/low pressure

ahh i only run it while i am here and down have a float on it or anything so its probably not that big of deal im guessing since it is only plugged in and running when the barrel needs to be filled.

 

[theMeat]

Yeah, but this is what makes the unit stop running when the float switch shuts. If it’s not working right then when the float switch turns off the product line the unit keeps running water through it but it all goes out the waste line, and cartridges get used up for no reason.
Good rule of thumb is change flow restrictor and auto shut off valve whenever you change the membrane

 

[JordanM]

Ok i will have them add it to my order or get one from amazon.

Using this calculator
https://www.hamzasreef.com/Contents/Calculators/CO2DIDepletion.php

and entering your numbers, we get

If the water is 15 ppm TDS, the % consumed by CO2 is 13%.
If the water is 30 ppm TDS, the % consumed by CO2 is 7%.

So you won't see a huge improvement by degassing the well water (about a 10% DI lifespan increase).

 

[JordanM]

Ok well thats good news. Hopefully the only issue is the membrane then. Im thinking of running the silicabuster, then the maxcap then a regular BRS Bulk Mixed DI. Does this sound right? Will the silicabuster and maxcap be consumed as fast as my current resin by the CO2 or will it last longer? Of course this will also have the new 99% membrane from spectrapure so I am sure that will improve things a bit.

 

[theMeat]

Think silicabuster right before the di resin

 

[JordanM]

So the maxcap first then silicabuster then the brs resin?

 

[theMeat]

When you say maxcap, do you mean the RODI unit itself?

Do you have a spectrapure RODI system?

 

[JMetaxas]

I chew through DI resin. Maybe 100 gallons per cartridge. I know it's high Co2 in my well water.

 

[JordanM]

No, I have the BRS system. I assume all these canisters will fit in typical 10" housings and the membranes are the same size as well?

When i say Maxcap I mean the maxcap Super DI. I bought this package with the silicabuster:

Yes, the membrane housings are interchangeable.
I use a spectrapure ro membrane in a melvesreef rro/di system

 

[JordanM]

Do the DI canisters fit in the carbon block housings?

 

[mfinn]

Do the DI canisters fit in the carbon block housings?

All the 10" canisters (housings) and different carbon blocks and sediment filters and pre-filled di containers should all be interchangeable, from the reputable vendors.




Had to add, as long as they are 10" sediment filter, carbon blocks, and pre-filled di resin containers.

Great info
Gotta love this site

So maxcap, then silicabuster.

Silicabuster is a di resin. So BRS resin after that is not needed, but should last a long time if you put it after the maxcap and silicabuster
