Filtration

Filtration is the process of separating solid material from a fluid mixture, this is done by use of a physical membrane, or filter, to capture only the solids that pass over it, while letting the fluid pass through. In the cannabis extraction laboratory, filtration is used at varying stages in the process, as well as in varying configurations.

When & Why do I need filtration?

Filtration is an essential part of the initial extraction process. While many extraction systems do incorporate a mesh sock, or bag, in order to keep particulate out of the solution, a second more fine filtration is almost always done. Often times filter media, like charcoal, diatomaceous earth, bleaching clays, and absorbents, will be added during this stage, as a means to selectively remove certain pigments, lipids, and various chemical compounds. At this point there is now no plant material, or particulate of any kind in the extracted solution and distillation can begin.
