Is there a reason?

Is there a reason that I shouldn't run two RO units at the same time . One after the other ?

I can't think of a reason you can't, unless it possibly has something to do with the DI water running through your filters again. Why it would damage them I do not know....

Ask Dwayne at MS. He is a water treatment guru. If anyone would know for sure it'd be him. Achillestang2002 I think he is on here....

I run two 90gpd in series...no probs.

Let's see some pics of that Zeovit tank!!

I would imagine you would want some sort of pump between them to create the pressure needed for it to operate correctly. I don't know that for sure but everything I have read states thta you need a certain amount of pressure for proper filtration.

Just started the zeovit only method back up .Give a couple months to get everything stable again .


How do you have yours set up with the two Ro systems ?

 

[Nanook]

I have mine in parallel....not in series. It is the standard Spectrapure 90gpd RO membranes.

my question is why would you want to? With a good set of filters and new DI resin you will get 0 TDS. So if you run it through a second filter what would you be accomplishing as you've already removed everything?? The only thing I can see that you would accomplish as you would be waisting a certain ammount of water as waist water through your second filter.. water that was perfectly good. And by creating more back pressure, you won't get as much flow through your initial filter there by making it less efficient. So the only thing I could see you gaining by doing this is making more waist water and less final product that isn't any better quality than if you were only using one filter.

That's my thought but I could be wrong... anyone have a contradicting thought?

John I would imagine you can run the effluent line from the first into the membrane input on the second. I never thought of hooking two together.
