I am looking into filter aids capable of dealing with the worst sludge coming from MHRB or P. harmala.
I usually reduce MHRB or harmala tea to manageable amount, then let it sit overnight to allow fine insoluble impurities settle.
Then I decant the supernatant liquid and filter the rest.
My current weapons for fighting the slught include:
- repeated addition of hot water, sedimentation and decanting
- glass wool, funnel + vacuum filtration
- Celite (diatomaceous earth)
When filtering harmala sludge, the only thing that currently works for me is making a pad of Celite inside Buchner funnel, then adding mixing few spoons of Celite into the watery sludge, then filtering it with vacuum on. This procedure is however still quite lenghty.
I was thinking about these aids:
- sand
- aluminium sulfate (coagulant)
The sand provides coarser filter that Celite, hence might improve filtration speed.
As for the aluminium sulfate, it is often use as water purification aids in swimming pools, because it easily adheres to impurities, then falling to the bottom. It should not be filtered though.
I am afraid however, the aluminium sulfate will grab harmaloids with the impurities (in re-acidified sludge).
I might give it a shot though, but currently the easiest method seems to be just top up the sludge-containing beaker with hot water, mix it a bit, then decant the liquid.
This way most alkaloids get extracted without the tedious filtration.
What do you think and what you use?
