Know Your Filter Media, A Concise Guide to Your Options

Filter wool can also be used as a biological filter medium. It is one of the best media to use in box filters, because it is easy to shape the mass of wool to fill the box nicely. Coarser media, like ceramic chips, tend to leave big gaps around the edges through which water will pass without being cleaned.

Charcoal - Wikipedia

Charcoal was also used historically as a source of black pigment by grinding it up. In this form charcoal was important to early chemists and was a constituent of formulas for mixtures such as black powder. Due to its high surface area charcoal can be used as a filter, and as a catalyst or as an adsorbent. Metallurgical fuel

Adsorbers have been used principally to control the emission of VOC. The control of VOC emissions typically reduces the concentrations from between 400 and 2,000 parts per million (ppm) to under 50 ppm. Adsorption technology can now extend the range of VOC concentration from 20 ppm to one-fourth of the Lower Explosive Limit (LEL).

Filtration - Wikipedia

Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated. Filtration, as a physical operation is very important in chemistry for the separation of materials of different chemical composition.
