Hi to all, got some powder to play with trying to remediate some eth extracted at -30C, not winterized.

First experiment: celite, bentonite, AC/PVPP mix.

Not too much Remediation…

Pass it 3 more times treu the same cake let see it then


Next attempt, duble AC/PVPP - Celite,
Clearly improving…

I will use the cakes for other really bad extracts…

Wich bentonite are you using ??
And what type if A-C ?
Is it hardwood ??

30% Activity PVPP, Calcium Sodic Activated Bentonite, and Selective Activated Carbon… No more info…

My Celite, and would like to try also:

Perlite Filtration Aid

But need to verify if compatible…

Calcium Sodic bentonite interesting
Whats the ph on that ? Sounds like 9-11 ph
Wich brand

Old cake running very dirty extracts…
