Activated Charcoal – Particle Sizes | Realize Beauty

02/12/2016 · The grade of activated charcoal I use is from Coconuts and it has a mean particle size of 15 microns. Mean = middle. That means that 50% of particles are SMALLER than 15 microns and 15% are bigger. Please note that this is the grade that I am using currently, there are SMALLER mean particle size charcoals out there and LARGER. It is important ...

Activated carbon • Chiemivall

In cases when it is not possible to use GAC, either because of the characteristics of the carbon itself or those of the process, powdered activated carbon (PAC) can be used. The tiny particle size of powdered activated carbon (PAC) makes it an extremely effective adsorbent with a shorter contact time as the carbon comes in contact with the molecule to be adsorbed much more quickly.
