Ive been using my lenticutlar setup for a few years now and i love it. one filter is good for 1000gallons or 500lbs of biomass being ran through it. you can get backflow plates to clean them even to stretch em. we get our tincture to -50c then winterize filter then go to a carbon filter at 110f.
Carbon lenticular filters are not meant for âfiltrationâ. The purpose of the carbon is for decolorization and adsorption of chlorophyl. If you took loose carbon, placed it in your tincture, and then mixed, you wouldnât call that filtration, nor would you expect it to remove your waxes/fats.
The reason we impregnate carbon into lenticular filters is so loose carbon does not have to be used in the production environment. If you have used it, you know it gets everywhere. Additionally, it forces contact time which eliminates the need for 20/30/40 minute mix times.
As for filtering with a carbon impregnated filter, yes, there are some filtration qualities due to itâs inherent composition. It starts with the same base, cellulose and a wet strength resin. At that point we add the filter aid. In this case Powder Activated Carbon (PAC), but in a lenticular manufactured for âfiltrationâ we would add diatomaceous earth (DE) or perlite to accomplish the bulk filtration. By just adding PAC, you loose the throughput and the efficiency of the DE as a filter aid. Therefore, you are really just filtering with cellulose, which does work, but does not have efficiency and dirt (wax) holding capacity as the lenticular with DE.
For a proper filtration train for cannabis extracted with Ethanol, you would be best to use the same steps found in our CannaSkidâ˘, Stage 1- Prefiltration Stage, 2 - Lenticular with DE, Stage 3 - Lenticular with PAC, Stage 4 - Final filtration
You can find the details on the CannaSkid⢠and all four stages at our website:
If you have any questions regarding filtration Iâm happy to help.

Donât know what size your lenticular is but you can almost certainly get considerably more gallons thru it by prefiltering with a bag filter of some sort. My lab went from getting a max of 10-12k lbs processed with a 2x16" Pall lenticular housing to regularly getting over 35-40k lbs processed by adding a #1 bag filter housing with 10 micron bags from Duda Diesel ahead of the Pall lenticular.

Hey Guys, we are a local sanitary filter housing and stainless steel equipment manufacturer in zhejiang province of China. Weâve exported huge Qty of lenticular housing, and bag housing you guys mentationed to the North American market, usually some of our clients process wine, some of them use it for CBD extract application.
We can supply singe housing and multi stages filtration skid, contact with me to get compatitive quotation roypxc@163.com

Hello EL_Z, we recommend a 0.45um or 0.2um membrane cartridge downstream of the carbon module to polish out an fines that may migrate downstream. Thanks, gregh@heyesfilters.com
@jws66m ErtelAlsop manufactures true plate and frame filters up to 36" square. Unlike the pig filter, which uses filter paper, our plate and frame filters utilize depth filter media (same filter media a lenticular uses). We have a good number of labs utilizing this technology as it can do 2 or 3 stages of filtration in the same pass, plus the filter media is much cheaper in sheet form as compared to lenticular form. The photo attached is a 12inch diamond model running 4 stages of filtration in a Connecticut lab. It utilizes 1" inlet frames on the first filter bank to capture biomass from centrifuge (acting as a pre-filter) and goes through a 1 micron depth media. In the second back it uses a high efficiency activated carbon, and in the 3 filter bank it uses 0.45 depth media impregnated with diatomaceous earth. Additionally, our filter media impregnated with Carbon Chemistryâs T5 could also be used in one of the stages.
If you have any questions feel free to reach out.
Thanks,

I would be very i treated in talking with you regarding using the lenticular filter with BBO

Is there anyway to replace CRC with a larger 16" lenticular Filter using Filtrox Bentonite and or activated carbon? Would there be an unintended consequence of catching tarps in the filter? The ASME housing I have is rated for 150psi, the filter material seems to be compatible with butane⌠Anything Iâm missing?
If you can find bentonite clay impregnated lenticulars Iâd say give it a shot?
Youâd definitely catch terps with activated carbon, and itâs important to check how the carbon was activated. Plus the usual orange glow of carbon filtered hydrocarbon extracts, which isnât necessarily a bad thing, more of a perspective thing. Carbon is very non selective relative to other options out there.
Zeta potential would be a concern possibly? like, one usually isnât concerned about âshear forceâ (not quite the right word) in a traditional column filter set-up, but possibly it may be a concern in a lenticular form factor?

@batches @Fungnificent ErtelAlsop manufactures bentonite lenticular but only in 12 inch at this time. You can use 12 inch filters in your 16 inch housing, but as expected the filtration area is less per unit.
