Q: Can this be used along with the 1:1 membrane? If so, do I end up getting better than 1:1 ro to waste?

Q: i currently have the The AquaFX Barracuda RO/DI 100gpd. 2 questions should i be doing some sort of maintenance/cleaning after each use and storage? Second question with the piggy back membrane i see there are 2 option 50 GPD and 100 GPD. I have plenty of pressure so if I purchased and installed the 100 GPD piggy back will my AquaFX Barracuda RO/DI now yield around 200GPD? Thanks

Depends on your water pressure, if you have enough water pressure to run the waste into the Piggyback; then you will basically cut your concentrate in half. If you have higher pressure then you will see a better result. Pressure is a factor that determines efficiency. So; the second membrane will produce 4 parts BUT you get twice the output. So you the overall is 2 to 1

Trevor,
That is a good question. We have not used the 1:1 membranes that way. The membranes are designed differently , so theoretically that should work. Keep in mind...the "waste" is actually a concentrate stream, the membrane splits the stream into permeate and a membrane rinsing concentrate stream. I believe we can safely say it will work, but for how long, until the membranes clog?

Good Morning, You just need to keep your membranes wet upon storage. If you have a flush kit, use it, before storing.

Water quality is important as well. If your water Quality is bad, running the waste into another membrane will beat up the 2nd membrane faster.
