Well Water Chewing through DI Resin
- Thread starter JordanM
- Start date
Might be easier to use two restrictors on each and then T them back into together after the restrictors. I know the larger the number the higher the waste ratio and lower tds you will have so if anything I want to go larger since im not paying for the water and it just goes back into the ground after.
Ok my ph is around 7.9 and the alkalinity is 300ppm from the Hanna HI755. I was gone for 9 hours to work today and you can see the di resin has been consumed twice as much as it was this morning and looks like it only made less than 1/3 of the barrel so about ~18 gallons of water. Please let me know if it is CO2 i am dealing with or just bad membranes as I want to get some water ASAP as i want to start the cycle on my tank. Still have OTDS coming out but the in is now reading 15 as i look at it but it was reading 30 when i got home.
Also just checked and this booster pump is tied into the afr605, which i am asuming is an automatic way to control the flow which states that it is rated for 500ml/min.

Im guessing this may be part of the issue as well since this is for a 50gpd membrane.

As someone who has been thru this personally with a private well of my own it’s a pain! I agree you need better rejection rates from the membrane but more than likely you co2 as well. Only way to deal with that is degassing the ro water before running it back thru the di canisters. I have tried a couple different ways of doing it and got tired of it. Spectrapure actually has a diagram of a degassing tube on their site somewhere. I found the process more than I wanted to deal with so now I buy resin from BRS in bulk and repack the
canisters. Yes I still burn thru resin but the initial cost of bulk vs prefilled canisters much less.
