I’m in exactly the same boat an im very interested in membranes for the same reasons, dry ice and winterisation.
How do we get these membranes ? i googled but with no luck.

Google: Nanofiltration membrane organic solvent, the top few results.
Sterlitech has a housing for the small membranes.
Look familiar?

I looked everywhere for that lolo, i could find pdf’s, contact e-mails… but nor price lol.
Thank you !

Idk if you could do co2
I have something better for terp seperation anyways I can do it with membranes
I was the first to start talking about the idea

Youll get that with an 1812

I member 
Lol
But yeah this would be a sweet idea to play with forsure for the c02 cats, I’ll send you over a write up I have that could help with r&d on it if you want

Very nice!
This post intrigued, Room Temperature Winterization and Solvent Removal - #90 by Noah
I thought thats pretty damn good for one cycle.
I think because a room temp extraction of butane is much different in terms of wax’s and lipid pickup vs room temp ethanol we’ll have an advantage there as well in terms of amount of clean up to do, assuming quality material.
Butane picks up way more fats and lipids

I would assume that your seeing waxes accumulating in early runs and dispersing in later runs, preventing the formation from being as large, clear, or fast to crystalize. I agree with the PH raising out of the effective range after multiple runs with any media types.
250 from an 8040 sounds right. An 1812 might do 30L, not 300L. Well… not more than once.

I clarified that was feed rate. Which is half of what @Kingofthekush420 said he feeds, @ 3gpm
Still confused on the ratio though, thinking of it as a batch or cycle process without inline recycling, if @noah is permeating 80% of his thc on his first cycle(previously linked), and lets say we are filtering 100g of oil/solute. So we dissolve in lets say 50:1 solvent ratio and have a 5L solution, in one cycle if we are as experienced as Noah we’d get 80% of our goods, so lets its 50% for average joe and 4 total cycles to call it good. We’re filtering 20L total(assuming adding back the same total of solvent). which at 3gpm or even 150lph we’ve cycled through our total in 8 minutes. I must be missing something!

Youre not gonna get 80% through on a single pass
Idk where you’re getting that info but its not in the link you provided.

I know I may not, but is he? or what am I not understanding about his statements, he says 20% rejection rate on the first cycle, so the rest is in the permeate no?
To be clear for everyone else reading along, “rejection rate” does not mean final cannabinoid conservation/loss. Roughly speaking, it refers to the amound of cannabinoid that does not permeate in one cycle

Hes saying the first cycle he gets 80% of the cannabinoids out
Then he does another cycle to get the other 17% out

The link before expired, which I didn’t know happened, but here’s the video put up earlier in the thread. I had to change the resolution and compress it a little bit

Can you expand on your experiences with ceramic membranes? Did you trial for both desolvation and winterization?
For all those interested in the tech, I found the following graph from Inopor to be extremely helpful in understand possible curves and not hard lines, pdf warning, pg 2 for graph: http://inopor.com/images/documents/downloads/en/productsheet/datasheet-ceramic-nf-membranes.pdf
And also thought I’d share just because this perspective blew my very high mind “if the tubular ceramic filters had the diameter of earth, they could separate out out tennis balls.”, Cleaning waste water effectively - YouTube
If the tennis ball is cannabinoids, a soft ball is the fats/wax, and the terps are a golf ball, floating in a sea of butane marbles.

Well done matey
Alright, this is an amazing place guys!
I do follow F4200 on IG!
Cool

Anyone can get stones in a scientific freezer. They crash out. It shows how your previous extraction method did. After they re up to room temp. You have to have the hand crafted intellectual property im your head to finish it off!
