Salt Water Mixing Stations Let's See Them

[TheWB]

I would say that if you measure the TDS from your waste water and compare it to your tap water, that would tell you if it's really worth your while. If it's higher from the waste line, than probably direct it off into your yard so it's not just running down your drain.

Thanks for responding. I live in the Pacific Northwest so there really isn't much of a need to water my lawn with the wastewater. What I'm more interested in is if there's a way to just keep cycling the wastewater through the ro/di system so that I get all processed water suitable for using in the aquarium with very little wastewater left. I know this is weird, I'm just sort of wondering if anyone had tried to do something like that and if they were successful. I'm thinking you would have to disconnect the water supply from the ro/di unit, put a pump in a container containing the wastewater and plumb it back into the ro/di unit and let it run through its process with that water.

I'm sure I'm overthinking this whole process but I figure I'm probably not the first person to come up with this idea so I thought I'd take a shot that someone on here might have tried to do it.

There are units out there that are made to have zero waste water. The problem tho is that they're very expensive. I'm sure you could try to achieve what you're describing and sounds like it would work in theory, but you would have to replenish your input water as it would become your product water.

The TDS of the waste water will be higher than the tap water. The TDS of your product water will be higher when you add a second membrane to use the waste water from the first.

Welcome to the real world, TheWB!

How many gallons of water you think is needed to wash a single blue jeans pants??

And for each nut you consume? How many gallons of water does that requires (per nut)?

How about a pound of beef?

It's unbelievable how much water is "wasted" in small daily things we can't imagine.

I do have an spectrapure, but didn't get the second membrane, but I also think it's a bad idea to run to the drain that water, so in the summer, I let my waste water to flow over my grass...

Winter is more complicate here in Colorado, but I'll think on something.

Also, you'll reduce your filter's life on passing again and again a high TDS water into your system. Oh, and of course, for a double membrane systems, you'll have to have more than 85 / 90 psi in your line, otherwise ot will not work well.

Thanks Fishresponse. The higher TDS of the wastewater never occurred to me. That's the obvious reason why an RO/DI unit doesn't come with some sort of re-circulation option. I figured there must have been a reason but I couldn't think of what it was so I asked the question. I still don't like the idea of wasting that much water but at least now I won't also waste a bunch of time trying to figure out how to modify my system when that wouldn't be productive.

FYI ruralking has 12% rebate sitewide right now for laborday weekend. Free shipping + 12% rebate on tanks isnt a bad deal.

What's the point of the valve above the pump in the line going from the pump to the top of the SW container? Is this to control flow rate?

If it is a true union ball valve and there is one before and after the pump it can be used to close off the pipe and remove the pump for maintenance, etc. Without having to drain anything.

Just finished setting mine up this weekend. I am using gravity to feed the RODI into the Salt Water container below. I then have the APEX DOS running my AWC.

This is my entry way closet. The hubby let me take it over. Hehehe and he did the plumbing, he's not into fish so I guess he loves me.

PB links repaired where possible.

Is the ball valve that some of y'all use on your outlet end of a pump just for flow control?

I"m referring to the double water tank set ups with the pump usually in between the water tanks.

Here is a shot of all my plumbing parts, Cepex Ball Vales and I will have two Spears True Union check valves as well on each side before the water hits the tee that will go into my PanWorld px40.

I am going with Two 25 gallon Ace Moto Vertical Storge Containers with lids with two 3/4'' buclkHeads. which i PICKED UP @ RuralKing for 65.00 a pcs with FREE SHIPPING. Every other place like Plastic-Mart, Tank Depot wanted more in shipping then the barrel. This time I'm going with Sch 40 BLUE pipe instead of the red I used on my station. Ones I am done with my station it will somewhat look like this one, see pix # 3. The only difference between mine will be it will have an extra Cepex ball valve on each side, incase I need to get a couple of gallons out of my fresh or saltwater barells.

What's the fittings for the bulkheads that is used in pic #3? I"ve got two 40 gallon ace moto's with a panworld 50px-x. Bulkheads are 3/4", but pump is 1" inlet/outlet.

Scratch the last couple of posts.

This is what I've done so far. Everything is dry fitted at this point. Will this set up work?

I added the tee and spout last minute so I can pump to the sump for water changes. Originally I was just going to gravity flow, but assuming the tee/spout works, do I even need the ball valves on each end at the bottom? Maybe just the right side for rodi water?

Salt water in the left and rodi water will be in on the right tank.

Well your end ball valves will let you drain the tanks to somewhere.

I rigged a bottom mix line on my salt tank as well to stir up salt.
You may want an easy way to get RO out for mixing additives etc. I use a siphon hose but a small faucet would have been cleaner.

Yeah, what about another ball valve above the spout (outlet to the salt tank)? I could then pump either water tank through the spout right?

I Still may keep the ball valves on each end of the bottom tho. Feels like a lot, but the options later could be useful.

Following. Planning on building one out of two 55 gallon drums

So my layout I'm hoping will be ideal. The tank is going on one side of the wall and the mix station will be on the other side in the garage. I plan on having one for RO storage and one for saltwater. On the plumbing I want a fill line that I can run to the tank and use for easy water changes.

So I have a newbie question. I have two 55gal drums plumbed together with a pump and my RODI unit overhead.. I have a heater and temp probe in the salt water barrel and the other barrel is for just RODI water.. do I have to have some kind of constant circulation in the salt tank to prevent the water from spoiling? How do you guys do it?

No absolutely not.
