Activated Carbon lenticular Depth Filter
Request a QuoteDescription
Powdered Activated Carbon (PAC) plays a critical role in the chemical, food & beverage industries, where it is commonly used for decolorization, removal of undesired by-products, and correction of taste, odor, and color profiles. However, the use of traditional bulk PAC has significant drawbacks in terms of handling the bulk carbon powder, cleaning process equipment, and the time and costs associated with carbon removal from the process. In contrast, immobilized activated carbon provides significant advantages in handling, cleaning, and cost saving. Lenticular modules with AC Series media filter alleviate these challenges by incorporating activated carbon within a robust matrix of cellulosic fibers, fully capitalizing on the benefits of immobilized carbon over conventional PAC. Moreover, AC Series immobilized carbon filter media exhibits superior adsorption efficiency compared to an equivalent amount of bulk PAC, significantly reducing overall process time and increasing product recovery.

Adsorption Capability
The pore size distribution of activated carbon determines its specific adsorption mechanisms. Key properties such as iodine number, methylene blue adsorption capacity, and molasses number define its performance characteristics. Pore sizes vary between micropores, mesopores and macropores. Macropores and mesopores generally serve as pathways for molecules to enter carbon particles and are critical to adsorption kinetics. Macropores function as transport pathways, while adsorption occurs in mesopores and micropores. small molecules, such as methylene blue(molecular weight: 319.86 Da), are primarily captured in micropores. Therefore, the methylene blue dynamic binding capacity is widely used by activated carbon manufacturers as a reference for decolorization efficiency. For Ac Series depth filter sheets,over 200 g/m2methylene blue is adsorbed.
