    Default Daddy, where does permeate come from?

    So...a brand new season ready to start....time to unpack the membranes from their preservative baths and flush them clean in preparation for the season! But wai! I used all my permeate for my end of season flushing/washing/rinsing! I certainly didn't keep a tankful all year long to develop mold and slime and whatevs.

    Where do you get your pre season permeate?

    I really only have access to city water and, if pushed, some well water.

    Anyone? Anyone? Bueller?

    I use city water. I pump it into my cleaned permeate tank and let it set for 3 days to minimize the chlorine, then I run my RO and flush , then do a soap wash 10 minutes, then a rinse 5 minutes minimum. I haul 275 gal,and I use it all to clean my 250 gph RO, then I'm ready to concentrate.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    1. Allow to sit in an open-top tank for 48 hrs. Sun and aeration/agitation will hasten the process.
    2. Find a local producer who has already concentrated sap and get spare permeate from them.
    3. Run city water through a deionizing cartridge (slowly).
    4. Use sap and toss the first concentrate out.

    I think I have a small bubbler pump lying around I can use to agitate/aerate. Thanks for all the suggestions!
