BRS triple DI saver ....

[ca1ore]

Ive been running the triple saver unit for a while. Cation never depletes, anion depletes the fastest and mixed somewhere in the middle. After changing the anion, I’m getting higher TDS after the cation and anion stages than before them. TDS is 8 out of the RO stage (and into the triple saver) but 16 after cation/anion then 0 after the mixed bed stage. Makes no sense to me. TDS should be lower after the cation and anion stages, and it’s burning through the mixed bed. Any ideas?

From what I've read this is typical after individual stages of single beds. Randy explained it somewhere I'll try and dig it up.. I know I get 0-1 after my RO membranes and 2-3 after my single stages then 0 out of my mixed bed...

I know the video .... says TDS after the cation jumps but after the anion it should be close to zero. Something is clearly amiss.

I was referring to Randy Holmes-Farley not Randy from BRS lol

ah, ok ....

Still odd because in the past mixed bed lasted a long time, now it’s depleting even faster than the anion. Maybe I’ll pull the unit apart to see if anything is observably broken.

Do you notice any channeling going on in the Anion stage?

No, I’ve actually become quite adept at packing the resin into the cartridges. Haven’t replaced the cation since I bought the unit, perhaps there something going on there. Odd ....

Humm... loose seal on the cartridge itself maybe?

I’m assembling the tools .... sledge, reciprocating saw, pry bar and steel toed shoes (those that follow my build thread will know why). I’ll get to bottom of it .....

Turns out that the cation was spent, but not observably so …. at least, not to my eyes. Partly user error as I had not used the sponge under the cap when putting the resin into the holder which allowed the water to partly channel. Back to TDS of 1 on the output of cation/anion.

Glad you got to the bottom of it! So the channeling allowed the interior resin to exhaust but kept the exterior portion from being effected so there was no noticable color change going on.

Yup ……. BRS guys had told me generally 5 anion to 1 cation .... I had gone through 6 anion so kind'a stupid on my part to have not looked more closely ..... sigh.

 

[ca1ore]

Having more issues with this unit ..... may dump it and go back to just using mixed bed. Replaced both anion and cation and getting 23 output after the two stages . &$*#@$. Maybe a bad batch of resin? Tired of wrestling with this thing.

how are you measuring TDS ?

 

[cvysochin]

I run 4 resin stages due to high co2. Cation-> anion -> anion -> mixed. 450 tds in, roughly 4 tds after RO membrane, then roughly 10 after cation, and 0 after first anion, 0 after 2nd anion. 0 after mixed. I've ran the same mixed resin for probably thousands of gallons, as long as I stay ontop of replacing the anion as soon as it exhausts (about 300 gal per cartridge). I used to never get more than 50 gallons per mixed resin cartridge = huge waste of $. If tds is anything above 0 after the 2nd anion, I know it's time to change the cation. It always takes a while for the tds numbers to settle after swapping resin. But, I did get a bad batch of cation once. Nonetheless, huge fan of BRS resins.. they've saved me a huge amount of money.

I’ll do a bit of work on it. Maybe it is just a bad batch of resin .... or the inline TDS meter is on the fritz. Funny how one piece of equipment always seems to be the problem child .... triple ‘saver’ for me I guess.

make sure inline probes are aligned correctly in water line. they can only go one way to read correctly

I just replaced my Anion and mixed yesterday and saw this same thing. Thought I did something wrong but in the end, you need to let the unit run for a while before it stabilizes out. After switching I was getting 12-14 in line 2 but 0 after mixed. Let it run for about 3 gallons and then I was getting 2 on Line 2 from then on out. Just took some time

Now I'm getting 32 on the output of the cation/anion. About to punt this thing.
