filtration of powdered activated carbon?

Recommended Posts

Hi Everyone,

I'm using powdered activated carbon to carbon filter my spirits but we're having trouble removing all of the carbon. Currently we're using a Pentek 10" cartridge filter with a 0.5 micron filter. It appears to remove all of the carbon but after a period of time we notice black sediment in the bottom of our bottles. What are other people using to filter out PAC? Any pointers or specific filter types/models?

Thanks!

I use granular for this very reason.

Anyone care to share what the advantages of PAC is over GAC? Is the (potentially) greater adsorptive surface area really worth the increased hassle to remove from the spirit?

There are more than one size granules for that very reason.

I can supply test size granules prior to purchase.

Powdered carbon can be easier IF you can filter it properly. It most definitely has a positive and profound effect of my distillate, I'm just trying to figure out the best way to filter it.

0.5 is too large for powder. Finish with 0.2 if you can. If your load is high, allowing to settle and decant is a good idea, as well as prefiltering at 1 micron.

Bluestar, thanks for the advice. What style filter do use? A simple catridge filter like a Pentek? Plate and frame? Any specifc models you could give me that you've had success with would be extremely helpful.

Thanks!
