    For all the home-builders of RO, I say just go for it. There's enough info on here for free to build one and be successful right out of the gate. I have 4 seasons on mine and I did not fully...

    I was quoting you a performance for a series setup. The recovery rate is not double (30% vs. 15% with one membrane) with 2 in series. It's 27.75% because the second membrane is starting with a...

    Your numbers make sense. There might be some minor total flow differences in real life though. Sap temp plays a role as does starting sugar content but you have the right idea on the theory. You...
  4. When you close down needle valves to increase...

    When you close down needle valves to increase pressure in the membrane, the flow across the membrane slows down and hence your concentrate flow decreases and permeate increases. However, the slow...

    It sounds more complicated than it is. You are just splitting the concentrate flow to discharge and recirculation. I am adding a membrane to mine and undecided about another pump. Easy enough to...

    True except the commercially made units sometimes have a re-circulation pump to keep fluid moving across the membrane while under pressure. It's a feature I wish I had. But, I do have a...

    Maybe your pre-filter is plugging and dropping the feed pressure to the membrane? If so, your permeate would would drop and possibly your concentrate flow would increase. At least in theory. When...

    I have this exact press. Hand pump works fine for 10-15 gallons of syrup depending on niter and how much DE. If the window plates are full of DE and you add more, you will have a tough time. I...

    When the niter in the sweet you poured back into the pan settles on the bottom of the pan, gases coming out of solution from boiling build up below the silt and "pop". Happens to me every year and...

    I picked up 190 gallons today and broke over 3500 gallons. After tomorrow, we "made it" since I was hoping for 3600 gallons. I think I'm at around 75 gallons made, maybe a little more. I am...

    I picked up 395 gallons today. Some of that was from yesterday and a little from the last run. Luckily no spoilage. I am still making fairly light syrup. It was running well when I pumped out...

    Same here on running out of energy. I had 1270 gallons from Monday through Thursday this week and the sugar was never below 2.3. I'm cleaning pans tomorrow and gearing up for another big week,...

    I find hot permeate for 24 hours works well but in the syrup pan I usually need to use vinegar. You could mix vinegar with the permeate and just bring to a boil then shut down. Pressure washer...

    Another 370 gallons today. I'm just over 1000 gallons in 3 days and it's still running. I had a feeling this would happen. Syrup still looks light to me but it should darken soon.

    You tee off the line right before the pump inlet and run from there to the tank. Put a weight on it to keep it submerged. I use a needle valve to regulate the flow. Just a trickle keeps the...

    I have 4x40 RO (home-built) and I use a recirculation line. The concentrate line tees after the outlet of the membrane and then to two needle valves. One goes to the concentrate flow meter, the...

    Exactly. I'm using a Delavan 70B 3.5GPH at 150 PSI. You may want a PSI gauge on the fuel pump so you know approximately how much fuel it's burning. Higher PSI, higher fuel consumption. I run a...

    One of best sessions I ever attended at Verona was the off-flavor class. It's well worth it to try the different off flavors. You will not forget them.
