RO unit membrane

Hi guys,

ATM I have a 50GPD rodi unit, and I'm looking to cut down on waste water.

So my question is, if I add another 50 GPD membrane onto the water water tube, do I need a second flow restrictor on the second RO membrane?

Thanks

Jonty

I'm assuming you mean the waste water tube. If so, I doubt it will work. RO membranes need about 40psi of water pressure to work and I doubt you get that much pressure from waste water.
