Types of Activated Carbon

Coal-Based Activated Carbon

Coal-based activated carbon is available in four principal types: bituminous, sub-bituminous, anthracite, and lignite. Its unique pore structure—comprising micro, meso, and macro-pores—makes it highly effective for adsorbing a wide range of contaminants, from small chemical molecules to larger organic compounds. Coal-based activated carbon by CarbonFresh is available in several forms, including granular (GAC), extruded (pelletized), and powdered, providing flexible solutions for various industrial and municipal applications.

Coconut Shell-Based Activated Carbon

Coconut shell-based activated carbon is distinguished by its high micro-pore content, which delivers superior performance in removing small organic molecules, as well as reducing disinfectant byproducts (DBPs) in drinking water. CarbonFresh's coconut shell-based GAC is the ideal choice for potable water filtration, industrial processes requiring precision adsorption, and recoveries of precious metals.

Wood-Based Activated Carbon

Wood-based activated carbon is characterized by a macro-pore structure, making it highly efficient in removing larger organic compounds such as MIB (2-Methylisoborneol) and Geosmin, as well as for liquid decolorization. It plays a critical role in food and beverage industries, especially for the improvement of product color and stability. CarbonFresh offers premium wood-based GAC solutions to meet diverse industrial needs.

Production Methods for Granular Activated Carbon

Granular activated carbon by CarbonFresh can be produced directly through carbonization and activation processes or through secondary re-agglomeration of powdered raw materials. This flexibility ensures that high-density, high-activity GAC is specifically tailored to meet unique industry requirements. Its robust structure leads to longer operational life and optimal performance in various filtration systems.

Applications of Granular Activated Carbon
