Technical Advantages

High Mechanical Strength & Cost-Effective Purification

Our coal-based activated carbon is manufactured from premium bituminous coal through steam activation, delivering exceptional hardness (>90%) and abrasion resistance for demanding industrial applications.

With iodine adsorption values exceeding 900-1000 mg/g and customizable particle sizes (4×6 mesh to 12×40 mesh), it ensures optimal performance in drinking water treatment, wastewater purification, and air filtration systems. The high bulk density (350-550 kg/m³) and superior CTC adsorption (50-90%) make it ideal for VOC removal, solvent recovery, and gas-phase applications.

Available in granular (GAC), powdered (PAC), and columnar forms for maximum operational flexibility.

FAQ

Q1: Why choose granular carbon over powder for sugar decolorization?

A: Granular carbon enables continuous counter-current operation, easier separation, and thermal regeneration - reducing overall operating costs versus single-use powder carbon.

Q2: What is the typical EBCT (Empty Bed Contact Time)?

A: For sugar applications, EBCT typically ranges from 20-40 minutes depending on liquor concentration and target color specifications.

Q3: Can DC be regenerated after use?

A: Yes, DC is suitable for thermal reactivation, recovering 90-95% of original activity after proper regeneration.

Q4: Is DC certified for food contact?

A: Standard DC meets food-grade specifications. NSF-certified variants are available upon request for specific regulatory requirements.

Q5: How does DC compare to wood-based carbon for sugar applications?

A: DC offers superior mechanical strength for continuous operation, while wood-based carbons may provide higher decolorization rates. The optimal choice depends on process configuration and economic factors.
