Subsequent layers, however, still have adsorbing sites and a capacity to adsorb impurity, which increases through the depth of the media.

The initial layers make first contact with the fluid and as time and increasing fluid volume is passed through this layer they are the first to become saturated with impurity.

Due to the depth (thickness) of the sheet, it is possible to consider the structure as being made up of a series of layers containing PAC.

This is due to process fluids more efficiently contacting carbon particles immobilized into a sheet matrix.

At an optimized flow rate, the probability of contact between the impurities and carbon particles is greater in carbon-impregnated sheets.

There are two reasons for the improved efficiency of sheet-based adsorption compared to bulk mixing adsorption processes. Pall can assist customers to select a suitable product from its range of activated carbon products. Once the specification is established, careful small scale or laboratory trials are useful to determine which grade of activated carbon works most effectively and how much carbon media is needed per volume of product. If over treatment occurs, the product may be irreversibly stripped of desirable color and/or aromas. If the process is not well defined, the final product might be under treated resulting in uneccessary rework. In either case, the process must be very well defined so that the results are repeatable. Sometimes the specification will be a measurable change like color, but in other cases the specification maybe based on a taste profile.

To successfully apply activated carbon to your process, it is important to carefully define the desired specification for the final treated product. Typical uses of activated carbon in distilled spirts are: The force is very strong, but works over short distances only and is sensitive to the distance between the carbon‘s surface and the adsorbate molecule. While particles may be removed, there is no significant filtration action. Adsorption is caused by London dispersion forces, a type of Van der Waals Force which exists between molecules. The varied pore structure gives the carbon its very large surface area (approximatley 2500 m 2 /g) and also allows the carbon to adsorb a wide range of compounds.Īctivated carbon works by adsorbing the compounds it is removing. It differs from graphite by having a random imperfect structure which is highly porous over a broad range of pore sizes which can be divided into three groups: Activated carbon mainly consists of elementary carbon in a graphite like structure. Activated carbon filtration is used to effectively clean spirits by removing impurities.
