Have 2 RO/DI units, can I run Waste water from one to the other?

I have 2 ro/di units and was wondering if I can take the waste water from one and run it to the other unit to make more water with less waste?

The first unit is a 4 stage unit with a prefilter/carbon block/RO/DI. The membrane is a 150gpd filmtec.

The second unit is a 5 stage with a 75gpd filmtec membrane. If this could be done, I would think I would not need the prefilter or the carbon block since this is already done on the first unit.

My water pressure is sky high if that matters at all.

Let me know your thoughts.

Thanks
Ray
