Air water ice RODi second membrane ?

[toky916]

Hey guys I have a air water ice 75gpd I was wondering if it's possible to add a second DI to this unit to help eliminate waste water.

Has any one done this to this exact unit ?

You cannot eliminate was waste water..
BUT you can add a second RO (NOT DI) to reduce the amount of waste per gallon of output.

I have a BRS 75GPD RO system and recently added a second RO membrane and increased the output to 150GPD. The output of the first membrane goes into the second membrane. So some of the wastewater is returned as clean RO/DI water, but there is still some wastewater.

How much is it a lot less ? I was thinking it was DI haha.

I've never measured it, but it looks like the same amount of wastewater but double the amount of RO/DI water. I have a 20 gallon storage tank that fills up in half the time since I added the second membrane. The BRS website says it cuts the wastewater by 50%.
