I’m putting Silica into the 3’ crc first then the B80 or T5. Much better flow.
try using the media the other way. b80 or t5 then silica. ive always had good luck with silica on the top of my stack.

Looks like silica is bigger than b80 so that’s why i did it. I have been doing it the way you are but the fines -1u-5u make make a mess of my disks.
I have a solution of you’re willing to actually do it.
yea. im game for anything that helps me learn

You should consider sharing with the rest of the class bet we all could appreciate the tip

just dm me
there are many solutions for fines. first is paper filters, or a depth filter ( i call it a tampon), or you can use a filter aid such as celite 545 or diotamaceous earth. staging sintereds-- 20 micron/5micron/1micron.
and pre rinsing into a different collection pre run. We could spend quite a bit of time talking about the many filter aids, proper cleaning and maintenance of your sintereds help too. basically keep the clay off the sintered and clean them right after use.

If using a 5 micron, then a 0.2 after the 1 would be redundant. Would only be a drop in pressure and slow down flow.

This is a good option. But swapping it for a clean one regularly would be best.
that was bad placement of a period. would have a /20 micron/5 micron/1 micron
Even the 1 after the 5 would be a redundancy. If you are going down to the 0.2 like above.
I have a couple things in this picture.
2x Jacketed spools
1 Jacketed collector with w/Pour Spout
1 lid
What’s the recommended micron filters for making this a crc column? 10u > 5u > then 1u or 2u?
why the 1u or 2u? just quality or is flow aided by this size?
a 10 micron is redundant and just adds cost/cleaning to your mix.
5micron for the majority of your powders (with some form of either depth media or a paper filter over it to keep as much out of the mesh as possible).
Then a 1um filter or ideally, something finer to ensure you don’t have ultra fine particles coming through. Some of this is opinion and some of this is backed up by testing:
I’ve found, depending on what media I use, a 1um filter by itself will still allow some degree of fines through (“dry” running media and distilling off to test carry over).
Now this part is definitely opinion, and I know @Dred_pirate disagrees here as stated above, however I DO like to run a 1um over my .2um filter. I don’t get a ton of buildup on my 1um through the .2, but I think it keeps my .2um flowing unimpeded for longer. But it’s certainly not a requirement. Or, just swap all your filter assemblies more often.
I am a very large fan of gochemteks high flow .2um filter. Almost no flow reduction due to the large surface area (when compared to a sintered disc). Though I’d love to see what else y’all are using out there for your final stage filters! I know some folks are having good results using rolled felt of some sort in between a 5um and a 1um filter as a super fine depth filter, however I personally feel that allows for operator error in allowing for incorrectly rolled filters to allow media through undetected.

Would you go with only one jacketed spool, mix all the media together, and not use the second spool?
Use spool to add more space to keep crc filled throughout run without over filling.better to layer media IME
I do a fast filter paper->medium filter paper-> 1 micron steel disc held in place by pressure and gaskets
