Engineered Excellence: Matching Activated Carbon Type to Contaminant Molecular Size

Engineered Excellence: Matching Activated Carbon Type to Contaminant Molecular Size

Selecting the right activated carbon is an engineering decision driven by the specific contaminant challenge. The most critical factor in this selection is the relationship between the contaminant's molecular size and the activated carbon's pore structure. Our factory specializes in producing three distinct products—Granular Activated Carbon (GAC), Coal Based Activated Carbon, and Coconut Shell Activated Carbon—each offering a unique adsorption profile.

Coconut Shell Activated Carbon is dominated by micropores, making it the best choice for small molecules like chlorine, VOCs, and light gases. Coal Based Activated Carbon offers a balanced mix, including meso- and macropores, providing a high capacity for medium-to-large molecules such as complex organic colorants, heavy metals, and industrial solvents. Granular Activated Carbon (GAC), regardless of its raw material base (which can be coal or coconut), is defined by its particle size for use in long-term, fixed-bed systems for continuous liquid and gas flow. By understanding the target impurities—small, medium, or large—our technical experts can guide you to the precise carbon product that maximizes adsorption efficiency, minimizes operating costs, and ensures optimal purification results for your specific application.
