Eliminating wastewater for Ro/Di?

Thanks for the tips Henry. Unfortunately, my Ro/Di is in the garage and my washing machine is upstairs on the second floor. It's simply not feasible for me to plumb the wastewater up there, and I'm certainly not going to carry a million buckets up there.

I do usually dump a bucket in the toilet after I dump the dirty water from a water change in it... to flush it clean.

You can add a second stage to your existing RO/DI. You don't need to replace it, just expand it!

I bought the add on di with a filled, refillable cartridge it was only 45 from awi. Took me about 2 mins to install. 2 push fittings and your done

Why not get some additional tubing and run the waste water to a drain or toilet some place? The water is almost at line pressure, so you can even go up. Since the tubing is flexible, you can easily fish it through walls and so on.

Also, just because it's called waste water as far as the RO/DI unit is concerned, it doesn't mean you can't use the water some place else.

interesting comment... i never though of that... this opens up a lots of possibilities... ::)
thx for the great idea! now i can advise others for the same. :)

BTW:
I am using Cati-Ani, the generation process did have some waste ~20 gals for Model-5 (for ~350g of water production in my case TDS=160+, GH=40+ ), according to the manual, if did it 100% precise, it will be neutral and can be reuse, BUT i will never trust that, and just dump them out. If you are not using a lots of water, probably be less headache to use RO/DI, no need to worry the recharging... IF there is some place near by me can recharge Cati-Ani, that would be excellent... oh, well, may be some 10+ yrs later when Cati-Ani getting more popular then.

Dave - I could probably get a longer piece of tubing and just run it out of my garage, or right into my bathroom in the house (right across from the garage entrance door). That is a good idea that I will consider, thanks.

I do use some of the "wastewater". I usually fill up a few small water jugs that we use to make iced tea and stuff with. I also fill up larger water jugs that I will take to water the plants and stuff, but not as much in the winter. This is really only a small percentage of what is "wastewater" though.

Malulu - You might want to talk to Richie (ricwilli) about recharging the Kata Ani. I know he recently got one and seems to have it all figured out now. I wasn't even aware of those systems when I bought my Ro/Di, or else I may have considered one.

Nick and Phyl - As far as adding a second stage, I might also consider doing that. My current setup has 3 canisters across the bottom, and then the 1 DI filter across the top. Click here to see it. How/where would I mount another DI canister to this?

I still find it funny that we give out tanks better water then ourselves! LOL

Reread Malulu's post....He has Kati Ani, in fact I think Richie learned from him.

Tanks, that unit pictured does not have DI on the top. That top canister is your membrane. You need to clip on another one of those and add some tubing to it to reduce some wastewater. Simply adding DI is not going to help with wastewater. I know the Filter Guys sells an add on Kit and all other vendors sell the components seperatly I believe.

If you are looking to upgrade, OGII is selling a RO/DI unit that has a wastewater ration of 1:1 instead of the usualy 1:5

Taz, I think it's funny that our tanks get better water than we do too, haha.

I did read malulu's post, and at the end he mentioned wishing there was a place nearby that recharged kata ani. If he taught Richie, than I guess that wouldn't help him. I just knew from reading Richie's build thread that he had some troubles but figured it out... so thought that might help malulu. I guess I should have reread Richie's post here to know that he did go to malulu's to find out what he needed to do. Anyway, they both obviously know how to recharge them, so this whole point is moot.

You are correct about the DI not being the top one, it is the one on the far left. I don't know what I was thinking when I typed that. :-[ I guess I was thinking I needed a "2nd-stage", and pictured what the 2-stage DI's look like (usually 2 filters across the top).

So you are saying I would need a second membrane and tubing + clips/hardware to reduce wastewater? Not another DI cartridge?

Mnat - thanks for the tip. As I said before, I don't think I'm ready to upgrade since my Ro/Di is fairly new, but I might consider adding a stage if that helps reduce wastewater.

just make sure it will not Freeze... else, when you expect some water generated over night, and then find out NONE in the morning due to the cold weather at night time...

charging the cati-ani is not fun, if i can find someone to do it, i would loved to hang it over... in fact i just did one charging on the past weekend, with Ron's help to take a lots of pics, and will post the steps within the next few days.
 
I dont know how far you can run the waste water line, i'm sure it will produce some kinda backpressure, don't know if it will have a negative effect though, just a thought
