How much water can be removed?
Hey all,
So on a 4x40 membrane, how high of sugar content can you go before the membrane starts to plug? I want to remove as much water as possible and with my upgraded 330 procon pump I will be able to process sap much faster than last year, meaning multiple passes. I have a recirc line on the unit. I can give more info if that is needed to determine output.

2022 - 210 on 3/16 shurflo, homemade vac filter & water jacket canner - 104 gallons
2021 - 215 on 3/16 shurflo, added 2nd membrane to RO - 78 gallons
2020 - 210 on 3/16 shurflo, upgraded hp pump on RO - 66 gallons
2019 - 150 on 3/16 shurflo, Deer Run 125 dolly RO - 73 gallons
2018 - 120 on 3/16 shurflo, 2x6 raised flue w/hood, homemade arch w/ AUF & AOF - 34.5 gallons
I use 3 4x40s and with recirculation i get to 10 sometimes 12%

Do you find your membrane performance drop off at a certain conc %?Originally Posted by OGDENS SUGAR BUSH

The performance possible depends on several factors. Some of those are pressure and the particular membrane. The higher the pressure you can attain, the more water you can remove, but on the flip side, the higher the pressure to more heating the concentrate gets and this heat is not good. What pressure do you expect? I just looked at the specs on one Procon 330 which showed 250 PSI as max. I only checked the one. At 250 PSI you may well need to run maybe 3 passes, remember, each pass raises the temperature which increases the microbial activity. Keeping the concentrate cold is vital. The best way is to match your RO output to the evaporator evaporation rate. However many of us on a limited budget can't do that.
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.
yes usually after 8% pressure starts to climb and i would have to open up the concentrate needle valve to keep the pressure down and the flow up
