RO Unit

[kain]

I apologize if I am asking in this in the wrong section. I have a RO unit that I need to replace the filters on. Initially it was set up for drinking water and has a reserve tank. The GPD is pretty low. I think I think I get like 1.5 gallons an hour or so. Is there any way to switch out the filters to increase the GPD? I am in the process of setting up another tank and would prefer it if I could get more than 1.5 gallons/hour. Thanks in advance.

That is rather low for our type of use. But since it's for drinking water what Tds is it on the way out of the last stage. Usually they don't have many stages unless it's a super ro. Also you will need a DI stage and probably better membranes.

There are a few sponsors here that will help you if you post on their forums, they might not troll around.

Cool thanks for the info. It's a 5 stage RO unit with a tank.

What you can do is get a new RO membrane rated for higher GPD and just change out the flow restrictor. I have no clue what your system looks like though and if it's even capable of that.

Jason over at Tropical Reef in Rancho can help you out he just got a bunch of RO/DI stuff in from BRS.

Exactly what I was going to say. Even the Tropical Reef part seeing where you are located. hahaha

Bring it with you, I'm sure he would help you get it it up to speed...

Hahaha, pain in the butt I know, but since they are all different, this way he can see what he needs to replace...

Use a better rated membrane and hook up a booster pump. Not only will it produce more but your good/waste water ratio will vastly improve.

Wrong thread my bad

I second the booster pump, and if your input water is really bad, I definitely recommend a prefilter on the pump to extend it's life...

Without the pump, it takes me 3 times as long to fill my storage container...(sometimes I forget to plug it in haha)
