I wanted to make a thread where we can post color remediation results from membranes.
Here’s my results from today using ethanol denatured with heptane
Crazy how well it worked. Hplc confirmed passage of terpenes and cannabinoid, I tried to winterize some of this stuff in methanol and nothing.
Super happy with these results.
Not be a party pooper, but can someone also post coas pre and post to show there is the same amount of cannabinoids if not more in the post processed awesome goodness?
Is that before vs after or retentate vs permeate?
In for the pictures! And data! Always the data!
These are RO filters? What psi do these operate at?
Unfortunately the in house analytical hplc my partner is running wont generate a print out
Ill have 3rd party testing done soon
This is nano filtration technically
The big membranes in one of my videos are ROs
This should allow me to do terpene seperation
Retentate VS permeate
Ill evaporate some as soon as I get enough for my 20L
Do you reprocess the retentate when running membrane filtration?
For water filtration the retentate is waste water correct?
Some water filters have a “recycle” option also you can use if its coupled with a softener.
That’s an arbitrary question that depends on what you’re trying to do. Yes retentate = RO waste water. However if you’re running solvent recovery, the retentate is your product.
I posted these before. Both in the medium of ethanol. Before vs after (retentate not shown)
With water filtration you dispose of the retentate instead of recirculating it
The permeate is the good stuff that makes it through
So these are “Nano filtration membranes”?
The winterization membrane that did this color remediation is
Anything promising on the horizon for butane?
How many times would you recirculate the retentate?
Also, thanks for humoring my noob questions, this is something new to the forum after a bit of slowness, so it’s definitely piqued my curiosity.
I got it, I asked Trinity to upload nanofiltration. Its basically a level before RO and depending on the way it laid(spiral/flat) coupled with pore size particles can be targeted. RO does not target and just filters everything out. The big + is being able to run lower pressures and specifically target particles.
Nanofiltration is a separation process characterized by organic, thin-film composite membranes with a pore size range of 0.1 to 10nm. Unlike reverse osmosis (RO) membranes, which reject all solutes, NF membranes can operate at lower pressures and offer selective solute rejection based on both size and charge.
You would circulate it till you reach your desired concentration or no permeate is coming out
ROs do not reject all salutes, if they did the PH of your water wouldn’t come out alkaline. You need a deionizer after your RO to fully remove everything.
There are some things that make it through RO and RO is generally anything below 100 Daltons in molecular weight.
The membrane im using for solvent seperation is an RO membrane
Nothing truly gets all solutes at. The tightest RO membranes typically look for 99.5% salt rejection
