Been trying since mid 2018. So far have only used Magsil PR, tried to layer powdered carbon, but totally blocked flow. The first pic is a before and after filter, the next couple of pics are same material but ran at different temps. Haven’t achieved a true “water” BHO yet, but using sub-par material, and only magsilPR, to date.
Wasn’t aware of you or OGcannabis, just took it from the pesticide remediation SOP, and figured it would work inline for CLS.
Very nice. It’s awesome to see that other people are and have been at it for a while.
Don’t go heavy on the clay.
That bottom one looks nice
This thread will be really helpful, and excited to participate in it. Those were literally the first runs we did. There are some better ones. But Im going to do some different filter packing tomorrow and will keep everyone posted as well. I just don’t have activated alumina, but I have everything else. So may it begin.
Nice what was the order you used your powders on this one?
These photos were taken almost a year ago, now. It can definitely be done at kilolab scale and speed, which is where most facilities operate in making shatter and other THCa products.
Im on the smaller columns by mid week… i was thinking surface area and patientky weaiting on a 6x3" w sintered disk welded in… but looks like considering what you saying about tighter in smaller columns i csn try this by mid week when powders arrive… Im down for that minimum order of 15kg too…Are you guys(carbon chemistry) in Co.?
What filtration was used to achieve these results?
I would love to know as well 
Cotton depth filtration, as I always use with alkane based cannabis extractions. The key is finding the right color removing media and applying it properly. This particular method was funded by my research benefactors, so they essentially purchased exclusive rights to use it. I can say you folks in this thread are getting warmer, though! 
This is fantastic. I’ll be trying this method on a winterized cryo etoh extraction very soon.
I need to spend like a day compiling all this data between these two threads really, but @Photon_noir hinted at the same thing mentioned by @Waxplug1 about a higher ph in the solution.
A point was made about bentonite clay and alkaline solutions vs acidic solutions earlier by @Cryo13.
I know in another thread, probably the degumming threads there is talk about increasing ph etc. I’ll do more research in the morning. Edit: I found a few tidbits about clear distillates with the use of mag-sil and/or cbleach(carbon and bentonite) and ph being related to the effectiveness of the mag-sil too in the Pesticide Remediation thread… Coincidentally from March of '18.
I can’t wait to apply the compiled data to a filter cake setup and hit you all up with my thoughts on how I’ll proceed. Sounds like there will be different temperatures to account for based on the solvent used too, thank you for that tidbit as well @Photon_noir.
I can’t wait to see what that extraction looks like after evap @Dred_pirate! Too bad about the pvpp though, I really thought we were on to something with that.
Am I looking at depth filtration wrong? My understanding from a quick read is it almost sounds like I could fill a matrix of cotton with my various types of filter media to help prevent channeling and increase the efficiency of the media itself?
Yep, we are in Aurora, CO
Matrix of Cotton to prevent channeling, you say? 
I’m wondering if maybe I used that word wrong, ‘matrix’, lol… I’m just thinking it sounds like I could fill a certain ‘tightness’ of cotton with my filtration media. I could really be understanding that all wrong, but I seem to remember encountering something like a powder filled cotton filter in other real world applications… Vacuum cleaners maybe? shrug Been busy sampling new material options today so this post is kinda everywhere… Some aquariums run a fine filter floss prefilled with ac. Any thoughts guys?
I saw a bunch of the wine adsobants coming in pre-made filters too.
I’m not ruling pvpp out. It’s back on the train. I got to get some in my dewax chamber partway down on the bottom triclamp. I put a filter ring in and paper, put a little pile there. After pulling it out, it “adsorbed” a bunch of colors. I will be trying this post dewax, as well soon.
@CuriousChemist22 and @Dred_pirate how did you guys incorporate the pvpp into your system. I haven’t posted much on this subject just been observing until my system is ready to incorporate fining agents. Any who what I want to try is get either pvpp or sparkolloid. Rather than making a filter patty I believe a combination of the pvpp and sparkolloid should be added to an in-line dewaxing chamber that way you can Maximize the surface area of these fining agents. If you read the application of some of the fining agents most of the sops have the agent being added directly to the product they intend on purifying. Then they agitate the solution and let the powders settle before filtering through a bed of celite and betonite. Then after the dewaxing chamber have it flow through filter some filter plates packed with celite,betonite and magsil. I also have another idea involving “cotton” and “steel wool”
I feel the pvpp will do best, after dewax. I want to stall after the dewax chamber in another jacketed clamber, and warm it up, in that chamber I want to put the pvpp and investigate this sparkloid. Then when I open that chamber through the bed of celite and bentonite.
During this time bringing the solvent to a warmer temp. The rumbling from the jacket should allow for the fining agents to do their work creating agitation until pressure is built. Also making recovery easier for me, as the solvent will be warmer and I won’t have to heat it
Man if you sypher through all that sounds a lot like my idea a while back…
Think we may be getting somewhere…
Where you please the last clear run after purged?
Yesterday’s? Small amount but it has zero color. I jarred it and letting it sugar. It was too runny for me to do anything else with.
Today’s came out really nice, but had some color, but still a win. I must have saturated it all the way through. I was also running out of silica when loading this one.
And I don’t remember that. We’ve been talking about it for a while now. Hahaha
Heating the solution definitely should help. I’ve been wanting to find a solution that will allow the run time to be just as fast or similar in time. I remember reading some of these agents are actually useful for removing fats and I feel that would be most logical to find an agent that removes color and and pick up fats to that way you can possibly speed up the dewaxing process.
Tomorrow or they day after I should be receiving my Sous Vide which should help with my recovery time. Once I have that issue solved I’ll re ordered my in line dewaxing spool and some fining agents/ absorbing agents so I can start making water clear extracts
