I made a little video on how I have been able to get my CDL 12" vacuum filter to work well. Hope this helps.

Never thought of doing that with DE - thank you!
I have been using a CDL vacuum filter for the past three years and here is a link to how I finally got mine to work well. Hope it helps:...
I have had the same problem and I believe it is air locked. Very easy to fix. You can turn the pump on and then pop the tubing out of the quick connect of the output side. Then put it back in. I...
Sorry for the late response but my account was locked for some reason and was just able to get back in. For new membranes you can flush with clean, non-chlorinated water, for about 1/2 an hour. I...
Sorry I haven't checked the site in a while. That happens to me as well so I try and clean my permeate tank as often as i can. I test it with my refractometer and although it reads 0 there is still...
sorry my account had been suspended for some reason. I have run my 6 membrane system in series, parallel and a combination of both. To process lets say 150 gallons of sap from 1.5% sugar to 7.5-8%...
Mattatuck Madness is my site and you are correct - you will not see pressure until you are processing sap. Good luck.

This is what I have developed over the past several years and my system performs well all season.
Glad it all worked out!
This sounds like a bad membrane and I would guess by that amount of sugar in the permeate that it is most likely your 2nd or 3rd one in series. Attach separate lines to each housing for your...
Don't worry about pressure when you are running water - most likely well under 100psi more likely around 60psi. You should also leave the needle valve wide open when flushing so there will be little...
I actually have had very good luck on drops and sap bags with Gorilla Tape. Not sure if it is smell or that they don't like chewing on it but it seems to work very well.
Still going in Watertown. My trees are located in a very cold area so usually 2 weeks behind everyone else.
Most of those membranes are rated for up to 300 psi most likely your water filter housing will leak first.
Over the past two years I have been running 6 membranes in series and have found that I am able to get an 8% concentrate starting from 1.5% sap in a single pass. If the sap is cold in the 30s about...
Here are some directions they have worked really well for me.

I was no longer able to edit the old website so I needed to take it down. Here is a link to the new one: https://sites.google.com/view/mattatuckmadnessmaplesyrup/home
eustis - have you closed the needle valve - this will create the back pressure that forces the water through the membranes. If you have please make sure you have it plumbed correctly. If not send...
Amazon.com 50 pack for 68 dollars...
MsBoucha - I would not let the soap solution sit in the membranes - it is a cleaner not a preservative. Permeate or in your case well water is enough to keep them moist. You can always just run it...
You are just about spot on with your numbers from my experimenting over the past several years. I run my system at a little higher pressure usually around 125-135psi and depending on the temperature...
In theory the 2 x 400s should perform better but I did not notice a difference in running 6 x 150gpd membranes and 3 x 400gpd membranes. The 400gpd membrane housings started to leak at pressure...
If you think of a membrane like paper towels. The material is in a long sheet and there are millions of microscopic holes so small that only water molecules can fit through. Then it is rolled up...
