    Default Off-The-Shelf Reverse Osmosis System

    I am wondering if any off-the-shelf R.O. systems, like these (see link below) would work for concentrating maple sap. Obviously I'd need to collect the waste line instead of the filtered-water line, but if this would work it would save me some time fabricating something.

    Thanks!

    Sure, plenty of folks doing that. Lot's of discussion on it here if you look around (search).

    For example,

    2018 - 20 bags, 1050L sap, 17.6L syrup

    Most of these systems have an active carbon filter and a remineralizer for drinking water. These would have to be removed. And just the RO membrane used

    Commercial RO’s work fine, the principal is the same except we keep the stuff they flush... I have a Nimbus CIV 4000. Simple procon pump with a recirc system. I can get 8% for 2.5 in one pass. It’s a great alternative to the expensive maple RO’s.

    agreeing with what everyone else has said, Id like to add if you can find one of the used commercial ones and want to use it, it will work fine. you will just have a bulkier setup with un needed stuff on it. I think You would be better off getting all new and make a compact setup. If its available cheap and you dont mind the space/mess of it all go with the used.

    Might want to take a look at this site www.robucket.com

    Apart from that there is great information here on the build your own diy RO setups. Building my own and using an aquatech pump rate 1200 gpd and 3 x 400 gpd membranes. On cold sap I'm hoping for 7% or better at 15 gph and on sap above 45f in excess of 20 gph. Also have a good dialogue going with the guy from robucket.
    2017- Started small- 90 taps and made 7 gallons. Long days and a few nights on a 1x2 and turkey fryer. Caught the bug!

    2018- Bought a homebuilt 2x4 and built a small scale RO. # of taps? (More then last year,), predominately Reds, @ 210, with about 90 on vacuum. Finished out with 21 gallons.

    2019- moved up to 100 gph procon for my home built RO. Small mods to the 2x4 arch. Worked on my vac setup and mainline. Set about 220 taps this year and finished with 21 gallons again.

    I presume you meant www.therobucket.com

    Anyone know where you can get those multiturn plastic needle valves used in that setup?

    Thanks. I use one similar to that too. I just find that its less than 1/2 a turn from fully closed to too far open, so I'd like something with finer control.
