Monster RO system. At my house.

joekool · Jun 5, 2014

I got this setup for my house do to saltwater intrusion in my well at the house. Tds at my house is 1770 range. But after tomorrow no more.
Unfortunately I won't be able to use all that waste water do to high salt content. I will however still use the RO waste water from my 6stage I will use for my fish tank. So you might say double kill on two RO setups but the house is one thing and my reef is another.

I have only some of the equipment in my garage and the rest is getting delivered tomorrow morning and will be hooked up.

Believe it or not the system is made locally in the USA thats amazing.

I will update as it goes.

Well that certainly is a serious piece of equipment there, should help save your RO/DI unit from a premature death... lol

Currently installing system. It's a monster. The company makes systems all the way to city size.
Posting more pictures soon.

Now that's a serious treatment system! Bet that set you back a little $$. Can't do without water though.

Cost is 5k ya not cheap but better than salt water at every faucet. That was why my tds was1775 now it will be much much lower. At least my other RO will last much longer.

Getting about 1.25 GPM with 3 GPM waste going to play with it. Guy sold it says he prefers to waste more so the membrane lasts longer. I personally would like less waste. He had it set to 4:1 so I adjusted it to closer ratio of 3:1 concentrate to permeate.

Just ran my inside RO for the tank and I'm down from 24to 26 tds to 1tds post membrane. So my DI will last much longer now going from 1 to 0 is not much. Oh yeah! :clap2:

Wow water is so nice. I took a shower and it felt great. Doesn't even need a softener. Everyone should have one.

Buckeye Hydro · Jun 13, 2014

Nice. The RO system IS a softener. A softener is a device the removes hardness - you can do this by exchanging the hardness for other ions (this is what a softener does), or by simply removing the hardness (this is what the RO does).

Looks like you have a back washing carbon tank, and then a 20" x 2.5" sediment filter in the blue housing on the unit.

You must have a needed valve on the concentrate line - I don't see adjustment knobs on the flow meters.

That's a 5 micron sediment filter

Buckeye Hydro · Jun 13, 2014

Is the feedwater to the RO softened?

Russ

joekool · Jun 13, 2014

Yes 5 micron sediment. No softener at all.
Haven't checked the of produced water yet but I get 0 tds after membrane on 6 stage in house.
There is a valve for the concentrate and one for pressure going into membrane. Running at 1.5 gallons permeate and 2.5 gallons concentrate.

There is a lot of salt in our well.

Wondering if I should go to a sediment filter lower than 5 micron

Buckeye Hydro · Jun 13, 2014

Concerning the amount of waste water - you have 2 issues to consider - 1) recovery (usually talked about in this hobby as the waste to permeate ratio). 2)The minimum concentrate flow for your membrane. Worry about No. 2 first, and then get what you can re No. 1.

2.5 gpm flow on a 4" membrane isn't enough! Run it like that and you WILL shorten the membrane life. Your concentrate flow should be no lower than 3.0 gpm. That's a 4" x 40" membrane - think of all that membrane area! Minimum design concentrate flow on a 4" is typically 3 or 3.5 gpm.

I worked through this very same issue (on a different size membrane) earlier this week with a commercial client that was only getting 5 to 6 weeks out of his expensive membranes.

Don't cheat on this!

You going to put some sort of cover over it? Would stink for the sun to make it deteriorate prematurely.

Buckeye Hydro · Jun 13, 2014

I agree.

Buckeye Hydro · Jun 13, 2014

Did you have your well water tested? How was the hardness? Maybe hardness wasn't an issue and a softener as pretreatment for the RO isn't needed.

Russ

joekool · Jun 13, 2014

They guy didn't test anything but the salt level but he does install a lot of these systems in my area. There was so much salt in my waster that the softener couldn't regen properly. They converted the softener into a filter and changed the circuit board.

He also had my concentrate at 4 gallons and permeate at 1 I would feel more comfortable moving it to 3:1 waste ratio. I'll move it to 3 instead of 2.5.

What is a good max pressure to run these big membranes at to be most efficient.

Also yes it is a back flushing carbon filter with something else in it like gravel.

Most of all the water is awesome. Spot free. Better than city water. I can wash my truck and not dry it but I do lol. Very nice to take showers with and my wife says her hair is softer.
