my no waste ro/di system

[kwa]

hello. im new to rodi system ect. I actually dont have a aquarium yet put do plan doing a small salt water setup in the very near future. but purchased a rodi setup for a organic gardening project to remove chloramines. i kept trying to figure out what i was going to do with my waste water. i have a 75gd with the the water saver setup. since i will be using it for organic gardening and only really got it to remove the chloramines out so i can have thriving beneficial micro organisms that the chloramines would otherwise kill. With all that being said. I seen how the water saver just recycle the waste water from the first ro membrane. so i was thinking why couldnt I just recycle the second ro membrane waste water through like a 2 stage carbon block and di. since i see people using ro wastewater for their gardens. I woul have both the ro water and the ro waste going through a carbon block and di dumped into the same storage tank. p.s. i have my ro setup at moment tied into the washer machine line, which im sure my pressure is greatly reduced because i have 2 ge 10"x4" whole house with chloroguard filters. as of know it looks like my waste to ro is 2:1 upto 3:1. i could install the same setup before the filters but feel like it would be less effective at what im trying to achieve(waste water would be potentially dirtier) since i plan on combing the water anyways. I hope this all makes since and any input/info/ideas would be greatly appreciated. im trying to stick with something so i can setup up officially. thanks again and to azdesert i seen you on several forums, since ive been researching rodi systems and would love to hear your feedback. p.s.my tab is about 150-155, waste water about 185-190, ro about 5

If you use ro water, the water would run through the carbon block and whatever comes out should be mostly free of chloramines, no? The ro just removes most of the dissolved solids, so are you sure you're actually looking for ro water? Don't you want the dissolved solids to help with your plants nutrientsm

I dont necessarily need ro your right as i got a away years ago with just a 3 stage filter setup . but got sold on the idea of a brs 6 stage universal rodi since that was specifically under the chloramine setups. plant nutrients is all in the soil. p.s. also plan on using my ro setup for drinking water. hopefully save a few dollars from not buying bottled water

If I'm understanding you correctly then I don't think that setup will work, at least not from a $$$ standpoint. Running your RO water thru the DI with a tds of 5, the DI resin will last you about 900 gallons. If you run your waste water thru it, then the DI will only last around 25 gallons.

Go check out the BRS video on Youtube on this very topic! Double DI is recommended for people with Chloramines in there water.

Chloramines are hard to get rid of i always wonder if that stuff they use for freshwater to help neutralize chlorine and chloramine if it really worked.
If so you could use it while mixing your water?
I'm asking not telling btw i don't wanna hear someone rant at me if it doesn't really work.

I always put a couple of drops of Seachem Prime in my RO/DI water just in case any chloramines made it thru. I can swear that many years ago that the salt makers put a dechlorinator in their salts.

thanks for the replies. i will look into the liquids. for whatever reason it doesnt seem like the liquid stuff to neutralize chloramines isnt widly used by growers, I will have to investigate a little more to see why this is. But off the top of my head it may have something to do with the chemicals used at least for more organic gardening. thanks again

Forget BRS, talk to long time vendors who really know what they are doing. I love their chemicals but they don't have a clue with RO. Water saving just is not that easy and there are way too many variables to sell a one size it's all system. Membranes must be flushed, there is no getting around it. Reduce the waste and the membrane eventually fouls and fails, driving your replacement costs up and treated quality down.
Legitimate vendors have been studying this for 3 plus decades or more and there is no simple solution.

Talk with vendors like Spectrapure, Buckeye Field Supply and PurelyH2o it even AWI and AquaFX, all have a much much better knowledge of RO/DI and will not steer you wrong. Buy your chemicals from BRS but leave water treatment to the big boys.

Seachem Primes you have to have double DI or use Prime. It breaks down the chemical Chloramine into ammonia and chlorine which together makes Chloramine.
It also neutralizes heavy metals and breaks down the ammonia which is left over after it breaks down the Chloramine to ammonia and chlorine.
Double DI grabs anything that passes through the DI first stage plus I've done my own testing in the past so that why I backed their video on BRS.

I'm just trying to direct people to very reliable information.
