Di resin turns brown after first use...(BRS)

[350gt]

I did my normal Saturday maintenance and I had some RO filters and resin I picked up from BRS a couple of weeks ago, so I swapped them...I let 5-10 gallons of water flush through there before putting the water into my mixing bucket. I then made 5 gallons for my frag tank and was about 5-10 gallons into my brute for my display tank when I noticed the color changed to light brown..... The same color it says that it turns when expended......It's never done this with buckeye resin......My membrane was replaced not to long ago, so what happened? I don't have a TDS yet, waiting to pick one up Wednesday... The one I had crapped out on me....Can my water be that bad? At the most 20-25 gallons ran through it before the color change.... Only half is light brown.....

[Sherita]

Sounds like you have some major tds coming out of your membrane. Borrow a tds meter and check your tds coming from the membrane going to the di resin. I bet you will find out it's really high.

[350gt]

Ya Louis is getting some Wednesday, so I guess I have to wait...

It took a couple of months for my resin from buckeye to change to any color....

Could my membrane be fried?

[Sherita]

It could be bad for some reason, but that would be unusual. It might not be well seated in the housing. I would take the membrane out and then reseat it in the housing. I think that's where I would start. If that isn't it, then I would give Russ a call at Buckeye.

When mine went nuts I tried everything. I wound up replacing it. Mine did the same thing, it was eating di resin like crazy. Never did figure it out.

[Cammed_02]

When you pull the membrane lubricate the black o-rings with some petroleum jelly. Some water may be getting past them and exhausting your resin.

[Gseclipse02]

i dont know if im going to the reatraunt in the morning but i have a service call i have to do around 6 ill meet you off the highway and let you use my tds meter .... lmk shoot me a text

[350gt]

I think it might not be seat properly..... Heard what seemed to be bubbles after I changed all the filters and fired it up....

I remember thinking to myself that I have never heard that noise before..... Well I did order more than one kit, so should I change out all the filters or just the resin?

All good JT, I crashed early so i missed your post. No sweat if you can't drop by....

Exactly what I'm going to try and do today.... Thanks!

[350gt]

OKay so thanks to JT i got access to some #'s.........

water entering unit 315ppm

Before DI resin 210

water leaving unit 002ppm


And whats totally puzzling is the water entering the membrane is reading at 410ppm higher than what is entering the unit...... it this normal?

[350gt]

thats with less than 30 gallons through it...

so your normal tap is 315

ur ro is 210

and di is 002?

im lost with the 410 whats that ?


ur membrane is shot it seems which is causing ur di to go also ..

[350gt]

yes tap is 315

and water leaving unit is 002

let me rethink the other parts its early...... LOL

[Gseclipse02]

lol....

[350gt]

its early and I woke up to find that my skimmer went nuts over night and dumped water all over my living room......

[Sherita]

Blargh, that's nasty.

is the 002 coming from the membrane, or from the di? What is the measurement coming out of the membrane? Also, the higher number coming from your prefilters indicates that you need to flush them. Disconnect the line from the prefilters TO the membrane and flush at least 5 gallons of water through there.

Looking at your di resin, it sure looks like your membrane has some issues. It's either not seated, the housing is cracked, OR you have the same weird problem that I had (which I could never track down).

First thing needed is the tds coming out of the membrane, before it gets to the resin.

[Sherita]

Ok, I missed one of your posts, sorry. Before di resin is 210. Your membrane is either shot, not seated, or has an internal crack that is letting water bypass. I would start by pulling the membrane and checking very carefully the o rings on the bottom for damage, also check the cup it seats in that is in the bottom of the housing. Somehow, water is bypassing your membrane. 210 coming out of the membrane is WAY too high. Should be more like 4-6.

[350gt]

RO water 260

after membrane 275

I think membrane was replaced january of this month.... need to look it up....

[350gt]

002 was in a 5 gallon bucket I made when I noticed the resin turned bad..... it was my last batch for top off water.


I checked again and 010 is whats being produced right now. I dont plan on using it and will check out the membrane in a minute. Might just order a new housing and membrane if I need to.

[Gseclipse02]

RO water 260

after membrane 275

I think membrane was replaced january of this month.... need to look it up....

the two measurements in theory would be the same thing ..... ro water and after the membrane is the same .....

[350gt]

im lost.......

keep in mind... I dont usually wake up until 10....

[Big_Pun]

if your getting high number after membrane either it's not seated right or it's shot...

[Big_Pun]

did you disconnect the line from the RO membrane and check water coming out it... the line that goes from membrane to the DI resin... sounds like you testing waste water

[alton]

I made the mistake of moving my Ro system in the garage this summer and my membrane did not last long. I have since moved it back inside the washroom

[350gt]

After membrane?

Before membrane

[350gt]

Is this thing even tube up correctly? Something seems wrong..


I did buy the unit used and never touched the tubing.. Except when I replaced the membrane.... Tell me I didn't...

[Big_Pun]

you have pretty fingers lol!!! yea you have some probs with the membrane. check if it seated properly . or just may need a new one. do you have a flush kit on the filter??

[350gt]

No flush kit... Going to pick one up and my own Tds meter from Louis this week hopefully...


And ya I use to be a finger model..... But just the middle one.

[Sherita]

Take a pic of the top of the unit, so we can see the tubing. That would be a good place to start.

You don't need a flush kit, just disconnect the line going from the last prefilter to the membrane. That will flush the prefilters without sending water to the membrane.

[350gt]

[Sherita]

I just sent you a pm with a link to a photo showing what tubing goes where. Should help at least eliminate that as an issue.

[350gt]

I have it all apart now...

But after the carbon it's going into the end close to the waste line out... Then exits the end cap to the Di resin...


Is this right?

[Sherita]

Call me 325-two one four-0135

Description does not sound right. Will be easier on the phone.

[350gt]

Wow thanks for the link......


It was all set up wrong.....


I guess this is why I blew through so much resin so fast.... The bulk reef stuff lasted way longer though....


Im an idiot.... Lol

[Big_Pun]

I'm home now if you want to bring it by I can check it out

[350gt]

Heading to work in a few.... Can you do me a favor and just take a pic of asov on yours so I can figure out which tubing goes into each socket...

[350gt]

Sherita was tons of help over the phone but we were limited as she has a different unit and different asov...


But thanks a bunch sherita....

I don't think I messed things up as the tubing was cut to specific lengths, so there was little to no way I hooked them back up in the wrong places..... But who knows..


Just want to tube it up right and see what happens.... I checked the membrane and the seal was in good condition... I have a extra set of filters that I will put on after everything is correct...

[Big_Pun]

home and location of my tank and gear are two diff places lol

http://www.bulkreefsupply.com/store/video?file_name=69

[Big_Pun]

also mine would confuse the heck out of you as I have two RO membranes piggy backed to make 150gph an there are lots of tubes lol

[350gt]

Lol thanks for the link....

The problem with mine is that I have a different asov

http://i712.photobucket.com/albums/ww125/gsrt5/54f28686.jpg

Most asov like sheritas are both in on one side and out on the other...... This one ofcourse has to be different... Lol

[350gt]

I made the mistake of moving my Ro system in the garage this summer and my membrane did not last long. I have since moved it back inside the washroom


Thanks, yes ever since that last discussion about RO units placement and temps in garages.. I have been looking for another place for mine.

[Sherita]

That asov is designed for systems with pressure tanks. Not likely to be the issue, but I can't say for sure.

I'm still saying that the tubing is wrong. It looks complicated, but it's really not.

housewater>prefilter/carbon blocks>asov in>asov out>ro membrane in (the single fitting in the screw on cap)>membrane>center fitting on membrane house goes>asov in>asov out>di resin. The offset fitting on the membrane housing goes to your waste line.

The flow restrictor should be in your waste line as it exits the membrane housing. It's a vital piece of equipment, as it creates backpressure so that the membrane can function properly.

Can you get a better pic of your asov where it's marked in and out. I can only see the upper part of it.

Thanks again sherita!......This is just a quick mock up as I will get all the tubes cut to size....


http://i712.photobucket.com/albums/ww125/gsrt5/ed305290.jpg


We lowered the Tds coming out of the membrane to 016!..... And now me pressure reads 52-55... It's been at 42 since I bought the unit...... Meaning I didn't retube it up wrong, it came that way... Just glad I can now enjoy real RODI water instead of wondering why my pressure was low or why was burning through filters....




Now to explain to the wifey why I mopped and why there is wet plastic baggies all over the garage.....

Sherita again, if there is anything I can ever do for you in town..... Lmk..

[BuckeyeHydro]

When you pull the membrane lubricate the black o-rings with some petroleum jelly. Some water may be getting past them and exhausting your resin.

Please DON'T use any petroleum jelly on o-rings. Food grade silicone grease only. Petroleum jelly will ruin the orings.

[BuckeyeHydro]

Your ASOV has a "horseshoe" type flow pattern, like the ASOV on the left below:
http://i224.photobucket.com/albums/dd293/BuckeyeFS/_MG_4800.jpg

The ASOV on the right has a "straight through" flow pattern.

We can email anyone instructions that cover both if the PM us a request w/ their email address.

Russ

[Sherita]

Glad I could help ya out. That TDS will probably drop to 4-6 after you run the first 5 gallons through there.

Your reef will love ya now :)

I was advised from Spectrapure to do this when my membrane wasn't seated correctly, fixed it right up.

[350gt]

Lol

Looking back at how it was set up..... I am wondering how it even produced water for me....
